It models unit economics (CAC, LTV, churn, cash flow, and runway) through an interactive multi-page dashboard. What was challenging: Styling Streamlit beyond its default look — injecting custom CSS for dark-mode cards. Also structuring engine.py to make the projections feel realistic. What I’m proud of: Turning simple code tests into a complete, clean SaaS-like dashboard and getting it deployed live on Streamlit Cloud. How to test it: Click “Try project” (its on Streamlit Community Cloud!) for the live demo. In the sidebar, go to Simulador (Simulator) , pick a scenario or tweak the sliders (initial cash, CAC, churn, price) to watch the metrics and charts update live.", "repo": "https://github.com/EngThi/ownStartup", "demo": "https://ownstartup.streamlit.app/"}]...

One thing that was bugging me was that I had originally put a video on the app, but Streamlit renders it with that standard video player UI (progress bar, controls, play button), which just didn’t fit the vibe of a dashboard. So I swapped it for an animated GIF instead! Now it sits cleanly on the simulator sidebar, looping nicely without any player controls getting in the way . For the simulator itself, I encapsulated the simular_cenario parameters into organized cards and blocks. It makes the data much easier to digest, pairing nicely with Streamlit’s native callouts like st.info with their own accent colors. On app.py , I also organized the other modules into their own structured cards. For navigation, I organized the sidebar options with clean selectable radio dots and unified the whole UI palette: Kept the standard Streamlit white and default accent colors (like the red highlights on active selectors). Replaced the plain look with a deep dark-slate / navy background, paired with crisp light gray for labels and titles to keep high contrast and readability. Added some extra CSS (which I used AI to help me dial in) to handle card borders, hover states, and spacing. Overall, it finally feels like a cohesive, custom web app rather than just a bunch of default Streamlit widgets thrown together ✨ ."}, {"post_id": 83822, "ts": "2026-10-28T17:48:47Z", "hours": 0.8639, "text": "I kept tinkering around here and made the initial version of the README .

Streamlit automatically picks it up like a slug/route to load multi-page navigation on the site, which is honestly really neat. Basically, for app.py I just wrapped up the integration and cleaned up the imports. In engine.py , the core logic was already pretty much settled, so I mostly had to finish tweaking the simulator interface itself. I also dropped a video showing the general UI along with some screenshots 📸. Man, after all that downtime coming back to it a bit last week and diving in way more this week I managed to make some serious progress!

Then, using the projected data returned by the function, I was going to use pandas and its DataFrame to pack and organize everything neatly together 📊. Later on, as I was testing things and brainstorming ideas with AGY , the plan is to turn all of this into a nice graph using Streamlit 📈 . There was a quick error showing up in the image — took a quick look, and it seemed like an unclosed parenthesis somewhere in the code. I poked around and tweaked it, but I’m not even sure if it was just missing, placed in the wrong spot, or had an indentation issue where Python didn’t register it as closing that specific call.

For now, I was thinking about actually adding the simulators and the whole core startup idea itself 📊. I created three files (haven’t really edited all of them yet), including engine.py . Basically, it’s a function I just put together that takes startup data monthly metrics and all that and runs tests and calculations related to, well, running an actual business.

I utilized the exercises I had already been working on—specifically the functionsand adapted them for the app. This includes the sections on statistics, data simulation, and so on. I’m not very experienced with CSS yet since I don’t use it often, I asked Antigravity to add some styling to give the page a more premium look, given that Streamlit supports the standard web trio (HTML/CSS/JS). I also came across FastHTML, which encapsulates these technologies; the API and the way it handles standard web operations using Python are pretty cool. It’s less abstracted and feels closer to “standard” web development. There’s a sidebar to access the sections I set up—four of them: General , Anomaly Detector , Statistics , Simulator , and Journal . Since I’m not fully comfortable with modularization yet and tend to get lost when the file or project size grows, that Agent helped me organize the code and use the correct functions and parameters.

Hi, I’ve started this new project… It had been a while since I last worked with Python , and when I did, I didn’t have my laptop with me. I was using Acode on my A05s , which wasn’t exactly great for development. Actually, I think it’s one of the best—if not the best—mobile options out there, but having the ergonomics and capabilities of a machine “built for the this” is so much better! I was sitting here wondering, “What kind of project should I do?” I wanted something useful. I know "useful" is subjective, but I look for things I connect with and find interesting (which inherently adds a bit of utility). I have a basic grasp of Python, but I haven’t done much hands-on practice—mostly just watching videos and doing class exercises last year. Because of that, I went a long time without building anything serious, and I decided there was no point in forcing myself to tackle something “advanced” right away. I started by writing a few things (what you see in the image) and testing some language features, but it didn’t really flow well, and I didn’t feel like I was actually learning anything new (truth be told, I already knew those little bits). In the course I’m taking now, the instructor uses C; I’ve been really digging into the fundamentals and practicing with hands-on exercises based on how C works that’s the approach I enjoy . Starting strong, mastering the basics, and building up from there. Since I never really did that with Python, I’m going to do it now! My plan is to work through some exercises, cover the language fundamentals, and eventually build a portfolio site—kind of like a project diary—using something like Streamlit or Dash. That’s about it. :)
I didn’t explain this earlier, but the exercises I’m doing are *mostly about file manipulation *sort of an introduction to Pandas and working with Data And that image there is of M365 Copilot . I managed indirectly to get access to it through the institution where I’m taking the course. I’m using it for studying and things like that. I asked it to generate exercises for me to do This first one asks to read numbers from a file and print the average
This new exercise was basically meant to read only the numbers from the file (specifically, integers). The template only included the letters/string "abc" but the code handles anything that isn’t a number because I used the isdigit function He mentioned that this exercise would involve try-except blocks, but I didn’t quite understand why at first. After completing my version , wondering about his comment, and imagining how it might work, I searched for the code block on Google ; using the AI-generated overview , I learned about the different types of exceptions (basically, the errors that could occur).
Man , this one took quite a while … I didn’t think it would take so long, and I thought I’d be able to do most of it on my own, but the for loop logic kept throwing errors because it was iterating over an index that didn’t exist I think its funny/strange how I forget certain things (I wouldn’t say easily ), even though it wasn’t that long ago that I learned or understood them. I don’t printed the final code… so get the source code on the repo: C3
This one was a bit different… what the M365 exercise wanted was for me to find values that fell outside the norm . I had studied variance and standard deviation back in school, but I honestly didn't remember anything about them . I managed to handle the initial part—up to the summation fairly well (more or less what’s shown in the image, though it was far from right) . I tried various approaches and attempted to recall the formulas or rather, not the exact formulas, but the underlying logic and the mathematical steps I needed to implement. I’ve included the simpleC4.py file here so you can see roughly what I was attempting earlier. I ran quite a few tests, executing the code after every new mathematical operation to verify everything was correct; I also had to comment out certain lines to debug and figure out how far the code got or what needed fixing.
I did exercise 6 . I skipped 5 , actually I think I started it pretty much, but I decided to come to this one. Here I had to enter the logs and see the occurrences of the events, only 'ok' and 'fail' . If there were failures , it would show how many there were . I even had the general logic, the code was well structured, but I was trying a defense loop right at the beginning of reading the user input. It had to be only ok and fail, so it was becoming an infinite loop. Actually, I wanted to do this input validation part: it can't be empty and only allows the strings I mentioned Then I researched and looked at some things until I put a piece of the code into Chrome and that overview created by AI appeared and simply gave me the input block ready… I was using: if len ( status ) < 1 or any ( resultado != permitidos ): # logic was using while True
M365 Copilot had assigned that exercise, but as I mentioned earlier, I skipped it. I didn’t quite grasp what it was asking for—I just did what I thought made sense and moved on to number 6… After finishing number 6, I asked it exactly what it wanted me to do, since I hadn’t understood the previous task. It explained something like this: you need to generate normal data and insert an anomaly. The dataset would consist mostly of normal values, with very few abnormal ones. It provided this pseudocode to illustrate the logic: if random < error_chance: generate unusual value else: generate normal value
So, for Exercise 7 , I basically took what I had done in the previous ones and combined everything. I would input the numbers, and the program would recalculate the z-score to determine the standard deviation component. It then displayed the input , the total , and any anomalies . That’s essentially what I did. I still need to improve an understand better the input validation and how I use the .split() function/method. I hadn’t included this image in the post, so: C7complted
This one was trickier . I need to improve how I use functions and keep variable scope in mind. This new file adds modularity to Exercise 7 . It contains functions for all the program’s processing tasks statistics , anomaly detection , results , status , displaying the report , and generating the report file . The part involving the file output was throwing an error because it didn’t recognize the total variable. I tinkered with it for a while, and since I’m using the Antigravity IDE , I decided to hand the problem over to the Agent , it basically changed the code to use len(dados) as a parameter (I really should have thought of that :| it was pretty simple, but I just got stuck). In the end, it was generating two files: one in the script’s directory and another in the directory where I was running it . (I use a "Run" extension (exactly Code Runner , so I just click it and it executes the file —whether it’s compiled or just the source code, since it’s an interpreted language.)
Now I’m working more with functions here. I made two simple ones that take three numbers as parameters and return the sum , and another that checks if the number passed as a parameter (int) is even . I had almost everything right, but I looked at it and thought "man, there's a way to improve/make this shorter" , so I sent it to * AI Mode on Chrome (I use it because it's much more integrated with search engines, can see websites, docs, stuff like that, forums, etc) and it gave me this which I thought was pretty cool : return num % 2 == 0 The result of this is a boolean value , and when printing you just need to check the value of the variable which is already True or False , and that’s it. Pretty cool …I had already done an exercise in C to check if something is a palindrome in my course.

There are methods/arguments used in string slicing that reverse the string and check if it’s a palindrome in just 5 lines of code… I really didn’t know that.
It ended up that I didn’t work much yesterday… I was studying Chemistry :/ Now I finished the palindrome function , I just had to pass the data, set the parameters, call the function, and that’s it. I’ll continue with the other two and then I’ll probably start the Streamlit part.
I finished the last two functions. Actually, they ended up being three because in the second file I did two. The first exercise was to return the price of a product with tax already included. The function received parameters for the value and the tax, and then I applied the tax to the value and printed it. The second one was a converter from 24-hour format to 12-hour format. For these two (I’d say both could use quite a bit of work) I didn’t put any input validation or code defense. Basically, that’s it.
I was working on improving the readability and logic of my files. Often , I’d finish an exercise and depending on the time just go to sleep or shut down my laptop without really testing whether the logic was sound. There were about two or three files like that, so I had to go back and tidy them up a bit . Now that I’ve started using Antigravity , I feed the file to the Agent , and it analyzes my logic, my solution, and so on.

What I mean is, if my logic and command of the tools are at a satisfactory level for the work I’ll be doing, I can move forward without worrying about making mistakes , forgetting things, or lacking a tool or technique I should have already mastered.
Today I started playing around with Streamlit. I took a quick look at the formatting and did some research to get a basic understanding of how it works. For now, I ran some local tests and eventually built this "little page" with it. Here’s what I used: st . text_input # For text input... st . write # To write text st . markdown # Renders Markdown formatting st . image # To render an image; I even added a caption Yeah, that was it.
I just started the app now. Before, I was looking, not exactly at the docs, but at the library’s syntax, some projects on Streamlit Cloud , the ones people like the most , and a bit of the repo to understand and see what it has to offer. I was just testing the colors here, formatting I saw there is the .streamlit/config.toml to configure its applications . In the images , I only made a sidebar and some kind of mocked options and put an icon that shows up in the browser tab :>
I spent quite a bit of time on this part… To give you a quick overview: I improved the app’s interface experimenting with various elements, especially the charts and related features. I utilized the exercises I had already been working on—specifically the functionsand adapted them for the app. This includes the sections on statistics, data simulation, and so on. I’m not very experienced with CSS yet since I don’t use it often, I asked Antigravity to add some styling to give the page a more premium look, given that Streamlit supports the standard web trio (HTML/CSS/JS). I also came across FastHTML, which encapsulates these technologies; the API and the way it handles standard web operations using Python are pretty cool. It’s less abstracted and feels closer to “standard” web development. There’s a sidebar to access the sections I set up—four of them: General , Anomaly Detector , Statistics , Simulator , and Journal . Since I’m not fully comfortable with modularization yet and tend to get lost when the file or project size grows, that Agent helped me organize the code and use the correct functions and parameters. It’s easy to forget things like passing file paths as strings, missing commas , or similar details errors that can take a long time to track down if you aren’t testing thoroughly throughout the development process.
After finishing those tests and kind of setting up that minimal dashboard with the anomaly generation, detector, statistics, simulator, and journal parts, I spent some time here and there testing out other Python stuff and everything. It’s already been four months I hadn’t really been able to work much on this back then, but now I’m back and I’ll be able to mess with it a lot more. For now, I was thinking about actually adding the simulators and the whole core startup idea itself 📊. I created three files (haven’t really edited all of them yet), including engine.py . Basically, it’s a function I just put together that takes startup data monthly metrics and all that and runs tests and calculations related to, well, running an actual business. Then with Streamlit , I’m planning to use its native components like charts and other widgets to organize things and make both the dashboard and the overall app interface feel way better . For now, I pretty much just drafted the function signature and a few test routines to get things rolling.
In this other part, I finished the function and everything else the general organization, the loop over the data, how the variance of the parameters would work, and the kind of things that happen inside an actual company, right? Basically this whole little startup simulation. I was also hooking it up into app.py to pull the dictionary. Then, using the projected data returned by the function, I was going to use pandas and its DataFrame to pack and organize everything neatly together 📊. Later on, as I was testing things and brainstorming ideas with AGY , the plan is to turn all of this into a nice graph using Streamlit 📈 . There was a quick error showing up in the image — took a quick look, and it seemed like an unclosed parenthesis somewhere in the code. I poked around and tweaked it, but I’m not even sure if it was just missing, placed in the wrong spot, or had an indentation issue where Python didn’t register it as closing that specific call. Basically, that was it for now!
For now, I basically made simulator.py run the simulation and have the data that will show up and the interface stuff on Streamlit . So that second image there is basically the file. I also took that data from engine.py to transform it and do all that. Then you can make the graphs and other stuff like that. Oh, I’m already sort of thinking about it, I was just looking here. It’s just that some sliders are missing, other input parts 🔢 , and then actually showing the metrics and plotting everything .
Here, I finished integrating what I already had in app.py . I had the simulators, module parts, and everything else now I hooked up the other apps into it, so everything is fully accessible! I set up the pages/ directory and moved simulador.py in there. Streamlit automatically picks it up like a slug/route to load multi-page navigation on the site, which is honestly really neat. Basically, for app.py I just wrapped up the integration and cleaned up the imports. In engine.py , the core logic was already pretty much settled, so I mostly had to finish tweaking the simulator interface itself. I also dropped a video showing the general UI along with some screenshots 📸. Man, after all that downtime coming back to it a bit last week and diving in way more this week I managed to make some serious progress! Things are feeling much smoother around here now, and it turned out really cool. I liked it! 🚀
I kept tinkering around here and made the initial version of the README . Basically, besides that, I added a requirements.txt and finished working on some things in the other files . And I also deployed it to the Streamlit Community Cloud . So now I have my demo URL and it’s available there, looking pretty good. I didn’t understand what caused that error. I don’t know if it was Zed's automatic saving 💾 or something like that, depending on whether I edited it and there was a space and then the parenthesis didn’t close. For me everything was OK, but it’s easy to fix…
I ended up tweaking and polishing a lot of things compared to the last devlog especially the colors, the general presentation, and how the dashboard elements sit together 🎨 . One thing that was bugging me was that I had originally put a video on the app, but Streamlit renders it with that standard video player UI (progress bar, controls, play button), which just didn’t fit the vibe of a dashboard. So I swapped it for an animated GIF instead! Now it sits cleanly on the simulator sidebar, looping nicely without any player controls getting in the way . For the simulator itself, I encapsulated the simular_cenario parameters into organized cards and blocks. It makes the data much easier to digest, pairing nicely with Streamlit’s native callouts like st.info with their own accent colors. On app.py , I also organized the other modules into their own structured cards. For navigation, I organized the sidebar options with clean selectable radio dots and unified the whole UI palette: Kept the standard Streamlit white and default accent colors (like the red highlights on active selectors). Replaced the plain look with a deep dark-slate / navy background, paired with crisp light gray for labels and titles to keep high contrast and readability. Added some extra CSS (which I used AI to help me dial in) to handle card borders, hover states, and spacing. Overall, it finally feels like a cohesive, custom web app rather than just a bunch of default Streamlit widgets thrown together ✨ .
Ships:
What I made: A startup financial simulator built in Python with Streamlit. It models unit economics (CAC, LTV, churn, cash flow, and runway) through an interactive multi-page dashboard. What was challenging: Styling Streamlit beyond its default look — injecting custom CSS for dark-mode cards. Also structuring engine.py to make the projections feel realistic. What I’m proud of: Turning simple code tests into a complete, clean SaaS-like dashboard and getting it deployed live on Streamlit Cloud. How to test it: Click “Try project” (its on Streamlit Community Cloud!) for the live demo. In the sidebar, go to Simulador (Simulator) , pick a scenario or tweak the sliders (initial cash, CAC, churn, price) to watch the metrics and charts update live....

Reviving my old project (and changing from slack auth, to hackclub auth…
sooo, quick one, addded slack auth again…for getting notifications….so orpheus knows that…but need to add some helpers and stuff now, meaning will be a small hustle to add that completely, also made a plan for the visualistaion….thank you, gooddd nighttt
soo, cleaned up the filesystem…aka dont have just one file anymore, but some more readable order….and tried making a slack notification helper…like when you get mentioned, a new message pops up in a thread you are in, you get a dm or smth…orpheus will show you, that part is not completely tested…soo could be that it does not work…dont know tho
Got notifications tunning…sadly cannot manage to make the onclick work yet, trying several things for that…web api…tauri notification plugin…and one more npm package i forgot, and nothings seems to work rn…this is my biggest todo rn bc i dont want the actual orpheus himself have any text…or buttons or anything on the screen…thats why i have choosen to make the config over notification that should open a modal
ouch….sooooooooooooooo Tried like 3 different approaches to make the notification onclick work on windows…first the web notification api with onclick handler, then tauri’s notification plugin with registerActionTypes, then even tried using the windows crate directly with WinRT ToastNotification.Activated events…none of it worked, turns out windows just doesnt fire any in-process event when you click a toast unless your app is properly registered in the start menu with a COM AUMID which is a whole thing ended up going with a system tray icon instead which is honestly the better solution anyway…left click opens the config modal, right click gives a menu with Open Config and Quit…no buttons or text on screen, orpheus just sits there being cute which is exactly what i wanted also cleaned up a bunch of dead code from all the failed attempts, removed the old permission flow, the test notification button, startup notification spam…its much cleaner now next up…idk man…smth fun, like ui, or homepage…no more backand for now (and sorry for calling orpheus he/him a few times, always forgetting it haha)
well after getting only slack notification…i asked myself…why not show also system notifications (only windows bc I dont even know if orpheus works on other os) yeaaa tried like 2 diffrent approches….settled on using the windows lib creating a nother tauri command…anddd its sad this complete thing took me almost 4h just to see orpheus holding a letter…like not even stacking letters…just holding them… and the scnd image is just the complete (hopefully final code for getting the image (got a little help by my friend deepseek for it in the end…i hate windows))...

Like istg, why do they have to be so strict? Anyway, you’ll see what i mean by that down below. THis session was all about fixing the deployment bugs. I was almost done and then these f bugs ruined it. This devlog has only abt 30 mins logged because i had the help of ai to fix this because this was way way out of my expertise. Here are the changes. I used ai for this devlog though cus i didn’t understand what it did (but i only used it for htis devlog): Problem 1: The [UNSUPPORTED_FEATURE] Vite Crash My very first Vercel build crashed immediately with a “Top-level await is currently not supported with the ‘iife’ output format” error. Apparently, the satellite.js library I use for SGP4 orbital propagation runs heavy calculations using Web Workers and WebAssembly. By default, Vite tries to bundle everything into an older iife format for maximum browser compatibility, which completely choked on the newer await feature inside the worker file. I fixed this (with the help of ai) by explicitly telling Vite’s internal bundler (Rolldown) to output modern ES modules for both the main thread and the background workers. I created a vite.config.js file and updated the configuration (see vite.config.js in the github repo) Problem 2: 404 Missing 3D Models After fixing the build, the site successfully deployed, but my 3D models (like the ISS and Hubble) and Earth textures threw 404 Not Found errors in the console. Because I was loading these assets while the app was running in my Three.js code using string paths (e.g., ‘/models/iss.glb’), Vite didn’t know they existed and simply excluded them from the final production build. I moved my models and textures folders into Vite’s public directory. Anything placed in the public folder gets copied exactly as is to the root of the final build. This bug wasn’t too bad but the next one was absolute hell. Problem 3: API, Cloudflare and CORS block This was the hardest part. Orbit Lens fetches live Two-Line Element (TLE) data for over 16,000 satellites directly from CelesTrak. It worked perfectly when i hosted it locally, but on Vercel, the browser instantly threw a 403 Forbidden error. CelesTrak uses Cloudflare to prevent automated scraping. When Cloudflare saw an Origin header coming from a deployed Vercel frontend instead of an normaly IP like my computer’s, it blocked the connection. Attempts to use public proxies (like allorigins) resulted in 408 Request Timeout errors because the multiple mb big satellite data took too long to transfer. To fix this, I used Vercel’s Native Rewrites (i have no idea how to use this so i asked ai to do it for me). “I” ;) created a vercel.json file in the root directory to act as a silent backend proxy. By fetching from my own local route (/api/celestrak), the browser doesn’t trigger CORS security. Vercel’s backend intercepts the request, strips the frontend Origin header that was triggering the firewall, and routes the raw data back to the application. This worked! And the website is finally live and i am about to ship the project!"}, {"post_id": 60005, "ts": "2026-09-02T03:10:06Z", "hours": 1.5539, "text": "OrbitLens Devlog #12: Added README.md and ARCHITECTURE.md In this session, i added the README and ARCHITECTURE.md.

Change 1: Firstly, i realised that the dropdown i had implemented was the default dropdown and it didn’t rlly fare well when there were 16000 items to choose from. So i made a custom dropdown, which looks much better than the default one, and made a funciton along with it that shows like the first 200 items matching the search query or, if nothing in being searched, the first 200 items in the list that the API gave. This made the entire experiene so much better because the default dropdown looked kinda ugly cus it took the whole length of the screen. Normally, this wouldnt take too long but i accidentally deleted the wrong eventListeners multiple times because satFilter and satSearch were so similar. So i spent like a good amount of time trying ot find the problem, and it turned out that i justmodified or deleted the wrong thing. Change 2: I found a problem with the filtering system, more specifically in filtering the space stations. Previously, i just had all the satellites with ISS or CSS in their names classified as space station because there are only two space statoins in space right now (ISS and Tiangong) so i filtered any satellites with those two names. But i failed to take into account that other satellites might also have ISS or CSS in their names so instead of two satellites showin up, 16 satellites were avaialbe in that filter. And these were not space stations but rather other statellits which had like ISS or CSS in their names (e.g. Swisscube). So i changed the filter to filter the space stations by their respective NoradIDs, which worked. Change 3: This change wasnt too big; i modified the expanded map layout becaues how it was before led to it having a lot of blank space and probalby wouldnt have looked good in differnet devices."}, {"post_id": 59360, "ts": "2026-09-01T03:31:31Z", "hours": 4.2022, "text": "OrbitLens Devlog #10: mobile layout implementation + better loading screen I am nearing the first ship of this project so this session were just about the final aspects that needed to be improved Change 1: I completely changed the loading screen. Firstly, it now displays the loading percentage that accurately shows the real time progress. Secondly, overall it just looks much better. Thirdly, i also implemented an error notification in the main dashboard in case the API doesnt work and so the website doesnt look like it’s broken Change 2: I added a mobile layout option. by that i mean that if the user is accessing this website on a mobile, it won’t be completely botched (hopefully) p.s. i know this devlog isnt that detailed as my previous ones and that’s because there isn’t much to talk about in this session cus the main changes were in the styles.css (and i’m hella tired)"}, {"post_id": 58733, "ts": "2026-08-31T08:54:43Z", "hours": 6.5158, "text": "OrbitLens Devlog #9: implemented satellite filtering + earth connecting line and complete UI overhaul Now that the website has a proper engine and everything was working well, i decided to add some more stuff. I had two goals for this session. One was to add a satellite filtering option where the user can filter categories of satellites. The other is to change the ui because there were many imprefectoins. Here is a breakdown of what i changed and the challenges i faced: Change 1: I added a global filtering system to fiter satellites by categories. To do this i first built a string-matching engine directly into the TLE parsing loop. As the engine downloads the TLE data from the API, it scans the satellite names and tags them each with categories. I didn’t really know what to categorise them so i thought of some categories and i asked ai to think of some categories. These are the categories: StarlinkOnewebCommsNavigationWeatherand Other/Miscallaneous (which i impemented later; read below) I then wired the HTML dropdown directly into the WebGL gpu loop. Instead of deleting unselected satellites (which would take up too much gpu memory), the gpu simply multiplies their matrix scale to 0, 0, 0, which would just hide them. But there was a challenge that i faced, though it wasn’t a big one. When i first implemented the filter, I noticed that the total satellite count dropped to around 12,000. It turned out that all the satellites that didnt fit into any cateogry were not shown at all so i expanded the categories to include an OTHER category. I also had to make some changes in the raycaster or the users would accidentally be clicking on the hidden satellites. Change 2: I also added a line connecting the selected satellite directly to its exact spot on the Earth’s surface directly beneath it. I did this by first pre-allocating a THREE.BufferGeometry with exactly two vertices. Inside the animation loop, i then took the satellite’s live 3D coordinates and use a .normalize() math function. Because the Earth has a radius of exactly 1, normalizing the 3d coordinates perfectly attaches the bottom of the line to the planet’s surface. But, i ran into a bug where the line would randomly disappear depending on the camera angle. After some research (ai) i found out that this was caused by Three.js’s “Frustum Culling.” The code calculated the line bounding box once when the websited started up and when the camera moved away from that initial box, the gpu assumed the line was out of sight and stopped rendering it to save memory. So i just added a line of code (frustumCulled = false) that just overrode that. Change 3: Lastly, i essentially completely rewrote the styles.css to change how the ui looked cus i didn’t relaly like how it looked before. So this was the third change."}, {"post_id": 57886, "ts": "2026-08-30T06:40:40Z", "hours": 6.5181, "text": "OrbitLens Devlog #8: Scaling the 3d globe and some other stuff In the last update, i finally implemented the 2d map so this time i want to take this website a step further since the foundation is stable enough. I decided to go from tracking 5 hardcoded satellites to over 16,000 space objects. Here is what i changed, how i changed it and the challenges i faced: Change 1: Originally, i just added the starlink satellites to what i already had which was my initial goal. but the thing was, i was requesting the API for thousands of satellites, which did work once and all of them were stored in localStorage but for ‘testing purposes’ (i was just stupif), i cleared the localStorage and re-requested the TLE which it then instantly rejected cus of its ‘anti-bot firewalls’ and i got ip banned for like a couple of hours and it gave a 403 error aswell. To fix this, i read some CelesTrak documentation and i realised that there is a way to ismply request all the satellite (every satellite that it had) data in one request. Apparently there was a special search query (‘active’) that i could’ve used but instead i individually fetched everything. So once i used that query, i got all of the satellitse (a bit more than 16000) rendered on the earth but it was laggy, which leads to my second change. Change 2 To fix this massive lag caused by the 16000+ satellites, I completely replaced the standard 3D mesh pipeline with THREE.InstancedMesh so that instead of creating 16,000 individual sphere objects (which would like instantly crashes the browser), i can feed the GPU a single geometry and material, along with an array of 16,000 matrixes. That means now the gpu like renders everything in one go. But, I hit a massive 5-second freeze whenever a user clicked the ISS (which makes sense cus this was a 4k extremely detailed 3d model). The thing was, WebGL delays uploading heavy 3D textures to the GPU until an object is actually rendered on screen. And because the ISS model was hidden on startup, the compiler skipped it, so the website was stuck trying to render it when i selected the ISS. I solved this by forcing the renderer to draw one “dummy frame” with all models visible during the loading screen, which, in a sense, ‘warmed up’ the GPU. Change 3: The lag was better but it was still there and i realised the problem was that each of the dots representing a satellite were smoothly moving in space. This smooth-moving physics applied to over 16000 dots was what slowed down the website. To fix this, I rewrote the loop that propogates the satellite dots so physics calculations wouldn’t choke the main JavaScript thread. To do this i built a system to process the satellites in batches of 4,000 satellites per frame instead of all 16,000. Second, i scrapped geodetic trigonometry (latitude/longitude conversions; see one of the earlier devlogs) and replaced it with direct Earth-Centered, Earth-Fixed (ECEF) 3D vector rotation. Initially, our batches were too small, causing satellites to visually ‘teleport’ instead of smoothly gliding, which looked really glitchy. But by upgrading to matrix rotation, i managed to get a huge increase in speed. This allowed me to crank the batch size up and get that smooth motion across the entire thing. Change(s) 4: There were still some small bugs in the visual aspects like the dots disappearing or the transition jump (see previous devlog(s) to understand) and stuff but i took care of them."}, {"post_id": 56499, "ts": "2026-08-28T09:22:18Z", "hours": 3.8858, "text": "OrbitLens Devlog #7: Implementing a 2D orbit map To expand the functinality of the website, i wanted to add a 2D world map that has the 3d orbit projected on to it. Here is a breakdown of what i built, how i built it and the challenge i faced. What I Built: I made a 2D projection of the 3d globe using the HTML5 Canvas API that runs at the same time with the WebGL 3D engine. The map automatically appears when a satellite is selected, and fetches live telemetry to draw exactly one full orbital period (half past, half future). The orbit line looks like how it does on the 3d globe with a yellow line representing the past trail and a dotted blue line representing the predicted future track. I also built an “EXPAND” toggle that expands the map to fill most of the screen if the user wants to take a close look. Challenges: If a satellite flies east across the Pacific Ocean (where the International Date Line is), its longitude coordinates suddenly jump from +179deg to -179deg. I originally didnt take this into account and it had like this massive, horizontal glitch streak entirely across the screen cus of the sudden coordinate shift. To fix this, I programmed a strict mathematical distance gate into the drawing loop. If the engine detects that the X-coordinate has jumped by more than half the width of the canvas, it forces the renderer to break the current stroke (mapCtx.stroke()), lift the ‘pen’, and begin a completely new path on the opposite edge of the map (mapCtx.beginPath()). When plotting a full 90-minute orbit, the beginning of the yellow line and the end of the cyan line do not connect perfectly, leaving a massive gap. I originally thought this was a problem and tried for quite a while to fix this and i double checked the math formulas again and again. But i realised this isnt a math error, it’s just physics. While the satellite flies in a continuous circle, the Earth is physically rotating underneath it. By the time the satellite completes one lap, the ground has shifted roughly 22.5 degrees to the east, pushing the satellite’s relative ground track to the west. So i just left it like that to accurately represent the Earth’s rotation. This was the biggest problem and took the most time to fix. Three.js orbital camera controls are incredibly aggressive about capturing mouse events. The 3D engine was always suppressing the HTML ‘click’ events, making the “EXPAND” button not work. Not only that, the standard inline CSS was pushing the 3D canvas down the page, which misaligned everything and didnt allow me to select the satellites at all. To fix this, fisrt, i locked the 3D canvas to a fixed background layer (z-index: -1) to completely isolate it from the UI layout. Second, i bypassed the WebGL event interceptors entirely and connected the code that handles the expansion directly to a global window function (window.toggleMap) and just injected the button with the HTML onclick attribute. This fixed everything and now it works really great."}, {"post_id": 55587, "ts": "2026-08-27T15:15:22Z", "hours": 6.2028, "text": "OrbitLens Devlog #6: Implemented Sun and the day night cycles + camera panning improvements The core engine was working smoothly, so this session was focused on the ui and aesthetics and realism. Here are the changes i made, how i made them, and the challenges i faced: Change 1: Implemented the Sun The first major goal was replacing the static and boring lighting the 3D earth originally had with a Sun. To do this, I wrote a custom Solar Ephemeris algorithm. Using the current Julian date, it calculates the sun’s exact Right Ascension, Declination, and Earth’s Greenwich Mean Sidereal Time (GMST) to pinpoint the real-time subsolar vector. Since this was some complicated math, i had to use some ai for this. But in a WebGL engine, lights are purely mathematical vectors and there is no physical object in the sky. So when i first added a solid white sphere, it literally looked like a flat plastic toy and looked really ugly. To fix this, I abandoned the 3D ball and built a 2D Sprite using the HTML5 Canvas API to generate a radial gradient. By using Additive Blending to the material, I forced it to mathematically layer the light over the space, which created like this blinding, light that looked like the sun, which was good. Change 2: The Day/Night City lights cycle: To make the globe even more realistic, I wanted the night side of the Earth to have like the night time city lights rather than just a dark shadow. To build this, I added an 8k night-map texture (from Solar System Scope) and implemented a WebGL fragment shader into the Three.js’s native MeshPhongMaterial using a compiler hook. But there was a problem, the free night map that i implemented had this blue tint to it, and when i tried to correct it, it literally turned to this muddy, polluted yellow. To fix this, I programmed the shader to intercept the texture data, remove the color tint by calculating luminance, and pass it through a smoothstep noise gate. Anything below a 10% threshold was forced to pitch black, while populated areas were recolored with a warm golden orange hue. And it worked great! Change 3: More camera improvements Despite the previous session having to do with correcting the camera engine, there were still some stuff that i fixed here. The problem was since i removed OrbitControls in the last session (read previous devlog), once i had like hte earth upside, it was very hard to make it upright again. like at one point, i had the entire europe upside down and Africa was at the top of the globe but i couldnt get it back to normal. To fix this I changed the code so that the panning controls thing swaps between OrbitControls (for the 3D globe) and TrackballControls (for the satellites/spacecrafts). But there were some more challenges: When a zoom-in animation (read previous devlogs) finished (after selecting e.g. a satellite), the camera would like glitch backward into a less zoomed in position which was kinds uncomfortable to look at. Because the satellites were moving a static transition speed couldn’t catch them before the animation finished, so the final frame was a bit glitchy and the screen like jumped a bit. To fix all of these problems, I first made sure that disabled camera controls are completely turned off so they can’t fight the active zoom animations. I also made it that instead of moving at a steady speed, I added a speed-up effect as the camera gets closer to the target. This ensures that the camera glides smoothly into place right on time without any jerky jumps."}, {"post_id": 55313, "ts": "2026-08-27T01:49:10Z", "hours": 7.3289, "text": "OrbitLens Devlog #5: Camera panning improvements and performance updates After the changes from Devlog #4, all the math and the 3d models were all working but i faced some problems in other aspects of the website. Here are soe of the changes i made: Change 1: Correct orientation This was a small change, but i noticed that some satellites were a bit too big (like Aqua) and were positioned wrongly, so i just chaged teh scale and the rotation to make it a bit more realistic Changes 2, 3, and 4: The camera improvements I faced a lots of problems with the camera and how it worked. Before, i couldn’t rotated in all directions around the earth or the satellites because they were using OrbitControls so i swapped that out with TrackballControls, which allows for 360deg panninh There was also like a rubber band effect where the camera, when the camera lock was selected as satellite, zoomed in towards a satellite, i couldn’t interact with the satellite at all. THis was because as the satellite’s moving, the camera is also actuvely trying to catch up so it never actually ‘ended’ its animation so i was blocked from interacting with the satellite. To fix this i implemented delta tracking. The engine now calculates the exact mathematical vector the satellite moves every frame and shifts the camera’s physical position by that exact same amount, which worked. Previously, switching targets caused the camera to travel in a straight line, clipping through the Earth, which looked kinda unprofessional so I engineered a custom transition that separates the camera’s direction from its altitude. Now, when you select a new satellite, the camera zooms out, tracels in a an arc over the globe, and zooms in to the destination satellite. The animation still needs a lot of improvement cus some parts are still a bit glitchy, but i’m happy for now. Change 5: I implemented it that the TLEs are now stored in the actual localStorage for like 6 hours and then fetch new TLEs. So the user will always have the latest TLEs cus they update evey 12hrs."}, {"post_id": 54315, "ts": "2026-08-25T08:17:16Z", "hours": 5.8253, "text": "OrbitLens Devlog #4: Adding multiple satellites In my last update, I finally got a 3D model of the ISS rendering on the globe with a basic UI dashboard. It looked cool, but I wanted to scale it up. I wanted to add multiple famous satellites on top of the ISS: The Hubble Space Telescope (HST)NASA’s AquaNASA’s TerraTiangongISS (which already exists) At least for now. Maybe in later stages, I can add Starlink satellites or sth. Here is waht I built, how I built it, and the challenges I faced. Change/Challenge 1: the orbit that looked like a slinky I hardcoded a 90-minute orbit line (the ISS orbit time). But other satellites have different orbital periods, so 90 mins fell short. Increasing it to a 12-hour calculation made the ISS orbit look like a massive slinky wrapping around the Earth cus its orbit is only 90mins. I fixed this by dynamically calculating the exact total orbit time using the satellite’s math: const periodMinutes = Math.ceil((2 * Math.PI) / satrec.no); const halfPeriod = Math.floor(periodMinutes / 2); Change/Challenge 2: IP ban (again) The JS fetch() doesn’t consider a ‘429 too many requests’ (i got this cus vite reloaded the page every time i saved something) response as a network error, so it tried calculating the HTML error page as orbital math and crashed. I fixed this by manually checking the response.ok HTTP status. If the API blocks me, the code redirects to an “Offline Fallback Mode”—loading a hardcoded string of ISS TLE math so the app survives. Change/Challenge 3: improper API request After like 4 hours, I realized I still wasn’t getting a proper API response even though the IP ban would have worn off. I looked at the code and realized I was pulling data for all five satellites in one go by just comma-separating the values in the URL like this: …/gp.php?CATNR=25544,20580,48274&FORMAT=tle (each number references to a satellite) But after CelesTrak’s documentation, it strictly dictated that the CATNR parameter only accepts a single catalog number. The server rejected the request, my code assumed 0 satellites, and the engine crashed. The fix: Writing five separate fetch() blocks is messy, and implementing an await fetch() in a for-loop creates a slow “waterfall” effect (waiting for one to finish before starting the next). I fixed this with JavaScript’s Promise.all. I created an array of the exact NORAD IDs, mapped over it to generate separate, perfectly formatted fetch requests, and Promise.all fires them all at the exact same time. Change/Challenge 4: I wanted 3D models for all of these. I found Aqua and HST easily from NASA. I found Terra, but it was fetching some other incompatible file I didn’t have, so I just scratched the Terra model. Tiangong was the biggest pain—everywhere I looked was either paid or on Sketchfab, and I cant create a Sketchfab account cus of some stupid Epic Games restriction. Implementing the files I did have was the next issue. Hardcoding multiple GLTFLoader blocks would turn the code into spaghetti. Plus, 3D models from the internet aren’t scaled equally—my Hubble was massive, and my Aqua model was tiny. The fix: I built a central Model Registry object. It maps a satellite’s NORAD ID to its file path and a specific scale multiplier. Even better, I implemented a fallback for satellites I done have a model for. If I track a satellite (like Tiangong) but leave the file path as null, the code detects this and dynamically generates a glowing cyan sphere using Three.js math to take its place. Changes 5 and 6: I updated the dashboard to include a dropdown to select the satellite and the telemetry updates accordingly. I also added a camera toggle feature where the user can lock the camera to follow the satellite or stay locked on the Earth. Lastly, I implemented a custom loading screen while the models load.

One was to add a dashboard which displays some stats of the ISS and the other is to replace the red dot with a 3d model of the ISS. Here is what and how I implemented these stuff and the challenges i faced: Change/Problem 1: Before I even got started on the new stuff i wanted to add, i faced a big problem. While testing the physics code and other stuff, my build tool (Vite) was auto-refreshing the browser every time I hit save. This I spammed CelesTrak’s public API with dozens of requests per minute. This lead to me kinda getting IP blocked temporarily, at least that’s what i think happend because it always returned an HTML error page instead of a TLE string. My engine tried to calculate stuff with that empty TLE and just crashed the engine The fix: It is important to know that a TLE is not like a live GPS broadcast that gets transmitted every second. It’s literally like a mathematical snapshot of a ton of stuff of the ISS like its position and its orbit and NORAD only updates these TLEs like twice a day or sth. So I fixed this api problem by making it such that the localStorage caches the TLE once and uses it for the calculation for the next 12 hours and then updates the TLE after that. Change 2: Dashboard implementation I implemented a dashboard that shows up on the top left of the screen and shows the following stuff abotu the ISS: Longitude: the method i used to calculate this is in one of my previous devlogs (i think my last one). But here is a quick summary: To find coordinates I first calculated the Greenwich Mean Sidereal Time (gmst), which gives me the exact rotational angle of the Earth at that specific millisecond. I passed the ECI position (one of the previosu devlogs) and gmst into satellite.eciToGeodetic(), which projects the point onto the spinning globe in radians. I then multiplied those values by 180/pi to convert the radians into standard degrees latitude: same as longitude -altitude: The eciToGeodetic() function also calculates the distance from the satellite’s coordinates down to the mathematical surface of the Earth (the WGS84 or the ‘World Geodetic System 1984’ ellipsoid which is like a mathematical reference representation of the earth that is used in calculatoin and stuff). It outputs this directly as height in kilometers, which I then simply rounded to two dp. -velocity: The propagate() function outputs the satellite’s speed broken into X, Y, and Z axes (measured in km/s). To get a single speed, I calculated the magnitude of that 3D vector using the 3D Pythagorean theorem: v = squareroot(x^2 + y^2 + z^2) Change 3: To implement a 3d model, i first needed that 3d image. I wanted the highest quality NASA model available (Model D - IGOAL). I downloaded the official .fbx, converted it to a .glb, and ended up with a 255mb file. Which is really bad because shoving a 255mb file into a web browser would just crash the entire thing. So i just ran that through a draco compression and a texture compression (WebP 1024x1024) which brought the size to about 18mb which was much better. To render this, I used Three.js’s GLTFLoader with a dedicated Google WebAssembly DRACOLoader to decode the compressed math. The next couple of changes were just to make it more realistic: i changed the scale from 0.02 (where it was the size of a continent) to 0.001 (which made it a good size) the direction the ISS faced was not accurate at all so I wanted to rotate until its in the correct position. But because the animate() loop was actively using math to point the model forward 60 times a second, it kept overriding my manual rotation.

OrbitLens Devlog #4: Adding multiple satellites In my last update, I finally got a 3D model of the ISS rendering on the globe with a basic UI dashboard. It looked cool, but I wanted to scale it up. I wanted to add multiple famous satellites on top of the ISS: The Hubble Space Telescope (HST)NASA’s AquaNASA’s TerraTiangongISS (which already exists) At least for now. Maybe in later stages, I can add Starlink satellites or sth. Here is waht I built, how I built it, and the challenges I faced.

Changes 5 and 6: I updated the dashboard to include a dropdown to select the satellite and the telemetry updates accordingly. I also added a camera toggle feature where the user can lock the camera to follow the satellite or stay locked on the Earth. Lastly, I implemented a custom loading screen while the models load. P.S.Lots of info is compressed cus i crossed the 4000 char limit.
OrbitLens Devlog #5: Camera panning improvements and performance updates After the changes from Devlog #4, all the math and the 3d models were all working but i faced some problems in other aspects of the website. Here are soe of the changes i made: Change 1: Correct orientation This was a small change, but i noticed that some satellites were a bit too big (like Aqua) and were positioned wrongly, so i just chaged teh scale and the rotation to make it a bit more realistic Changes 2, 3, and 4: The camera improvements I faced a lots of problems with the camera and how it worked. Before, i couldn’t rotated in all directions around the earth or the satellites because they were using OrbitControls so i swapped that out with TrackballControls, which allows for 360deg panninh There was also like a rubber band effect where the camera, when the camera lock was selected as satellite, zoomed in towards a satellite, i couldn’t interact with the satellite at all. THis was because as the satellite’s moving, the camera is also actuvely trying to catch up so it never actually ‘ended’ its animation so i was blocked from interacting with the satellite. To fix this i implemented delta tracking. The engine now calculates the exact mathematical vector the satellite moves every frame and shifts the camera’s physical position by that exact same amount, which worked. Previously, switching targets caused the camera to travel in a straight line, clipping through the Earth, which looked kinda unprofessional so I engineered a custom transition that separates the camera’s direction from its altitude. Now, when you select a new satellite, the camera zooms out, tracels in a an arc over the globe, and zooms in to the destination satellite. The animation still needs a lot of improvement cus some parts are still a bit glitchy, but i’m happy for now. Change 5: I implemented it that the TLEs are now stored in the actual localStorage for like 6 hours and then fetch new TLEs. So the user will always have the latest TLEs cus they update evey 12hrs.
OrbitLens Devlog #6: Implemented Sun and the day night cycles + camera panning improvements The core engine was working smoothly, so this session was focused on the ui and aesthetics and realism. Here are the changes i made, how i made them, and the challenges i faced: Change 1: Implemented the Sun The first major goal was replacing the static and boring lighting the 3D earth originally had with a Sun. To do this, I wrote a custom Solar Ephemeris algorithm. Using the current Julian date, it calculates the sun’s exact Right Ascension, Declination, and Earth’s Greenwich Mean Sidereal Time (GMST) to pinpoint the real-time subsolar vector. Since this was some complicated math, i had to use some ai for this. But in a WebGL engine, lights are purely mathematical vectors and there is no physical object in the sky. So when i first added a solid white sphere, it literally looked like a flat plastic toy and looked really ugly. To fix this, I abandoned the 3D ball and built a 2D Sprite using the HTML5 Canvas API to generate a radial gradient. By using Additive Blending to the material, I forced it to mathematically layer the light over the space, which created like this blinding, light that looked like the sun, which was good. Change 2: The Day/Night City lights cycle: To make the globe even more realistic, I wanted the night side of the Earth to have like the night time city lights rather than just a dark shadow. To build this, I added an 8k night-map texture (from Solar System Scope) and implemented a WebGL fragment shader into the Three.js’s native MeshPhongMaterial using a compiler hook. But there was a problem, the free night map that i implemented had this blue tint to it, and when i tried to correct it, it literally turned to this muddy, polluted yellow. To fix this, I programmed the shader to intercept the texture data, remove the color tint by calculating luminance, and pass it through a smoothstep noise gate. Anything below a 10% threshold was forced to pitch black, while populated areas were recolored with a warm golden orange hue. And it worked great! Change 3: More camera improvements Despite the previous session having to do with correcting the camera engine, there were still some stuff that i fixed here. The problem was since i removed OrbitControls in the last session (read previous devlog), once i had like hte earth upside, it was very hard to make it upright again. like at one point, i had the entire europe upside down and Africa was at the top of the globe but i couldnt get it back to normal. To fix this I changed the code so that the panning controls thing swaps between OrbitControls (for the 3D globe) and TrackballControls (for the satellites/spacecrafts). But there were some more challenges: When a zoom-in animation (read previous devlogs) finished (after selecting e.g. a satellite), the camera would like glitch backward into a less zoomed in position which was kinds uncomfortable to look at. Because the satellites were moving a static transition speed couldn’t catch them before the animation finished, so the final frame was a bit glitchy and the screen like jumped a bit. To fix all of these problems, I first made sure that disabled camera controls are completely turned off so they can’t fight the active zoom animations. I also made it that instead of moving at a steady speed, I added a speed-up effect as the camera gets closer to the target. This ensures that the camera glides smoothly into place right on time without any jerky jumps.
OrbitLens Devlog #7: Implementing a 2D orbit map To expand the functinality of the website, i wanted to add a 2D world map that has the 3d orbit projected on to it. Here is a breakdown of what i built, how i built it and the challenge i faced. What I Built: I made a 2D projection of the 3d globe using the HTML5 Canvas API that runs at the same time with the WebGL 3D engine. The map automatically appears when a satellite is selected, and fetches live telemetry to draw exactly one full orbital period (half past, half future). The orbit line looks like how it does on the 3d globe with a yellow line representing the past trail and a dotted blue line representing the predicted future track. I also built an “EXPAND” toggle that expands the map to fill most of the screen if the user wants to take a close look. Challenges: If a satellite flies east across the Pacific Ocean (where the International Date Line is), its longitude coordinates suddenly jump from +179deg to -179deg. I originally didnt take this into account and it had like this massive, horizontal glitch streak entirely across the screen cus of the sudden coordinate shift. To fix this, I programmed a strict mathematical distance gate into the drawing loop. If the engine detects that the X-coordinate has jumped by more than half the width of the canvas, it forces the renderer to break the current stroke (mapCtx.stroke()), lift the ‘pen’, and begin a completely new path on the opposite edge of the map (mapCtx.beginPath()). When plotting a full 90-minute orbit, the beginning of the yellow line and the end of the cyan line do not connect perfectly, leaving a massive gap. I originally thought this was a problem and tried for quite a while to fix this and i double checked the math formulas again and again. But i realised this isnt a math error, it’s just physics. While the satellite flies in a continuous circle, the Earth is physically rotating underneath it. By the time the satellite completes one lap, the ground has shifted roughly 22.5 degrees to the east, pushing the satellite’s relative ground track to the west. So i just left it like that to accurately represent the Earth’s rotation. This was the biggest problem and took the most time to fix. Three.js orbital camera controls are incredibly aggressive about capturing mouse events. The 3D engine was always suppressing the HTML ‘click’ events, making the “EXPAND” button not work. Not only that, the standard inline CSS was pushing the 3D canvas down the page, which misaligned everything and didnt allow me to select the satellites at all. To fix this, fisrt, i locked the 3D canvas to a fixed background layer (z-index: -1) to completely isolate it from the UI layout. Second, i bypassed the WebGL event interceptors entirely and connected the code that handles the expansion directly to a global window function (window.toggleMap) and just injected the button with the HTML onclick attribute. This fixed everything and now it works really great.
OrbitLens Devlog #8: Scaling the 3d globe and some other stuff In the last update, i finally implemented the 2d map so this time i want to take this website a step further since the foundation is stable enough. I decided to go from tracking 5 hardcoded satellites to over 16,000 space objects. Here is what i changed, how i changed it and the challenges i faced: Change 1: Originally, i just added the starlink satellites to what i already had which was my initial goal. but the thing was, i was requesting the API for thousands of satellites, which did work once and all of them were stored in localStorage but for ‘testing purposes’ (i was just stupif), i cleared the localStorage and re-requested the TLE which it then instantly rejected cus of its ‘anti-bot firewalls’ and i got ip banned for like a couple of hours and it gave a 403 error aswell. To fix this, i read some CelesTrak documentation and i realised that there is a way to ismply request all the satellite (every satellite that it had) data in one request. Apparently there was a special search query (‘active’) that i could’ve used but instead i individually fetched everything. So once i used that query, i got all of the satellitse (a bit more than 16000) rendered on the earth but it was laggy, which leads to my second change. Change 2 To fix this massive lag caused by the 16000+ satellites, I completely replaced the standard 3D mesh pipeline with THREE.InstancedMesh so that instead of creating 16,000 individual sphere objects (which would like instantly crashes the browser), i can feed the GPU a single geometry and material, along with an array of 16,000 matrixes. That means now the gpu like renders everything in one go. But, I hit a massive 5-second freeze whenever a user clicked the ISS (which makes sense cus this was a 4k extremely detailed 3d model). The thing was, WebGL delays uploading heavy 3D textures to the GPU until an object is actually rendered on screen. And because the ISS model was hidden on startup, the compiler skipped it, so the website was stuck trying to render it when i selected the ISS. I solved this by forcing the renderer to draw one “dummy frame” with all models visible during the loading screen, which, in a sense, ‘warmed up’ the GPU. Change 3: The lag was better but it was still there and i realised the problem was that each of the dots representing a satellite were smoothly moving in space. This smooth-moving physics applied to over 16000 dots was what slowed down the website. To fix this, I rewrote the loop that propogates the satellite dots so physics calculations wouldn’t choke the main JavaScript thread. To do this i built a system to process the satellites in batches of 4,000 satellites per frame instead of all 16,000. Second, i scrapped geodetic trigonometry (latitude/longitude conversions; see one of the earlier devlogs) and replaced it with direct Earth-Centered, Earth-Fixed (ECEF) 3D vector rotation. Initially, our batches were too small, causing satellites to visually ‘teleport’ instead of smoothly gliding, which looked really glitchy. But by upgrading to matrix rotation, i managed to get a huge increase in speed. This allowed me to crank the batch size up and get that smooth motion across the entire thing. Change(s) 4: There were still some small bugs in the visual aspects like the dots disappearing or the transition jump (see previous devlog(s) to understand) and stuff but i took care of them.
OrbitLens Devlog #9: implemented satellite filtering + earth connecting line and complete UI overhaul Now that the website has a proper engine and everything was working well, i decided to add some more stuff. I had two goals for this session. One was to add a satellite filtering option where the user can filter categories of satellites. The other is to change the ui because there were many imprefectoins. Here is a breakdown of what i changed and the challenges i faced: Change 1: I added a global filtering system to fiter satellites by categories. To do this i first built a string-matching engine directly into the TLE parsing loop. As the engine downloads the TLE data from the API, it scans the satellite names and tags them each with categories. I didn’t really know what to categorise them so i thought of some categories and i asked ai to think of some categories. These are the categories: StarlinkOnewebCommsNavigationWeatherand Other/Miscallaneous (which i impemented later; read below) I then wired the HTML dropdown directly into the WebGL gpu loop. Instead of deleting unselected satellites (which would take up too much gpu memory), the gpu simply multiplies their matrix scale to 0, 0, 0, which would just hide them. But there was a challenge that i faced, though it wasn’t a big one. When i first implemented the filter, I noticed that the total satellite count dropped to around 12,000. It turned out that all the satellites that didnt fit into any cateogry were not shown at all so i expanded the categories to include an OTHER category. I also had to make some changes in the raycaster or the users would accidentally be clicking on the hidden satellites. Change 2: I also added a line connecting the selected satellite directly to its exact spot on the Earth’s surface directly beneath it. I did this by first pre-allocating a THREE.BufferGeometry with exactly two vertices. Inside the animation loop, i then took the satellite’s live 3D coordinates and use a .normalize() math function. Because the Earth has a radius of exactly 1, normalizing the 3d coordinates perfectly attaches the bottom of the line to the planet’s surface. But, i ran into a bug where the line would randomly disappear depending on the camera angle. After some research (ai) i found out that this was caused by Three.js’s “Frustum Culling.” The code calculated the line bounding box once when the websited started up and when the camera moved away from that initial box, the gpu assumed the line was out of sight and stopped rendering it to save memory. So i just added a line of code (frustumCulled = false) that just overrode that. Change 3: Lastly, i essentially completely rewrote the styles.css to change how the ui looked cus i didn’t relaly like how it looked before. So this was the third change.
OrbitLens Devlog #10: mobile layout implementation + better loading screen I am nearing the first ship of this project so this session were just about the final aspects that needed to be improved Change 1: I completely changed the loading screen. Firstly, it now displays the loading percentage that accurately shows the real time progress. Secondly, overall it just looks much better. Thirdly, i also implemented an error notification in the main dashboard in case the API doesnt work and so the website doesnt look like it’s broken Change 2: I added a mobile layout option. by that i mean that if the user is accessing this website on a mobile, it won’t be completely botched (hopefully) p.s. i know this devlog isnt that detailed as my previous ones and that’s because there isn’t much to talk about in this session cus the main changes were in the styles.css (and i’m hella tired)
OrbitLens Devlog #11: Semi-final changes In this session, i focused on finding small aspects that need to be improved and improved them. Change 1: Firstly, i realised that the dropdown i had implemented was the default dropdown and it didn’t rlly fare well when there were 16000 items to choose from. So i made a custom dropdown, which looks much better than the default one, and made a funciton along with it that shows like the first 200 items matching the search query or, if nothing in being searched, the first 200 items in the list that the API gave. This made the entire experiene so much better because the default dropdown looked kinda ugly cus it took the whole length of the screen. Normally, this wouldnt take too long but i accidentally deleted the wrong eventListeners multiple times because satFilter and satSearch were so similar. So i spent like a good amount of time trying ot find the problem, and it turned out that i justmodified or deleted the wrong thing. Change 2: I found a problem with the filtering system, more specifically in filtering the space stations. Previously, i just had all the satellites with ISS or CSS in their names classified as space station because there are only two space statoins in space right now (ISS and Tiangong) so i filtered any satellites with those two names. But i failed to take into account that other satellites might also have ISS or CSS in their names so instead of two satellites showin up, 16 satellites were avaialbe in that filter. And these were not space stations but rather other statellits which had like ISS or CSS in their names (e.g. Swisscube). So i changed the filter to filter the space stations by their respective NoradIDs, which worked. Change 3: This change wasnt too big; i modified the expanded map layout becaues how it was before led to it having a lot of blank space and probalby wouldnt have looked good in differnet devices.
OrbitLens Devlog #12: Added README.md and ARCHITECTURE.md In this session, i added the README and ARCHITECTURE.md. The README.md highlights the basic features of the website, the tech stack used and how to run this project locally. The ARCHITECTURE.md goes deeper into how the code itself works so anyone perusing it can get a better idea on how i built this project.
OrbitLens Devlog #13: fixing deployment bugs 😭😭 Before i continue with this devlog, let me start by saying that modern security rules are the worst. Like istg, why do they have to be so strict? Anyway, you’ll see what i mean by that down below. THis session was all about fixing the deployment bugs. I was almost done and then these f bugs ruined it. This devlog has only abt 30 mins logged because i had the help of ai to fix this because this was way way out of my expertise. Here are the changes. I used ai for this devlog though cus i didn’t understand what it did (but i only used it for htis devlog): Problem 1: The [UNSUPPORTED_FEATURE] Vite Crash My very first Vercel build crashed immediately with a “Top-level await is currently not supported with the ‘iife’ output format” error. Apparently, the satellite.js library I use for SGP4 orbital propagation runs heavy calculations using Web Workers and WebAssembly. By default, Vite tries to bundle everything into an older iife format for maximum browser compatibility, which completely choked on the newer await feature inside the worker file. I fixed this (with the help of ai) by explicitly telling Vite’s internal bundler (Rolldown) to output modern ES modules for both the main thread and the background workers. I created a vite.config.js file and updated the configuration (see vite.config.js in the github repo) Problem 2: 404 Missing 3D Models After fixing the build, the site successfully deployed, but my 3D models (like the ISS and Hubble) and Earth textures threw 404 Not Found errors in the console. Because I was loading these assets while the app was running in my Three.js code using string paths (e.g., ‘/models/iss.glb’), Vite didn’t know they existed and simply excluded them from the final production build. I moved my models and textures folders into Vite’s public directory. Anything placed in the public folder gets copied exactly as is to the root of the final build. This bug wasn’t too bad but the next one was absolute hell. Problem 3: API, Cloudflare and CORS block This was the hardest part. Orbit Lens fetches live Two-Line Element (TLE) data for over 16,000 satellites directly from CelesTrak. It worked perfectly when i hosted it locally, but on Vercel, the browser instantly threw a 403 Forbidden error. CelesTrak uses Cloudflare to prevent automated scraping. When Cloudflare saw an Origin header coming from a deployed Vercel frontend instead of an normaly IP like my computer’s, it blocked the connection. Attempts to use public proxies (like allorigins) resulted in 408 Request Timeout errors because the multiple mb big satellite data took too long to transfer. To fix this, I used Vercel’s Native Rewrites (i have no idea how to use this so i asked ai to do it for me). “I” ;) created a vercel.json file in the root directory to act as a silent backend proxy. By fetching from my own local route (/api/celestrak), the browser doesn’t trigger CORS security. Vercel’s backend intercepts the request, strips the frontend Origin header that was triggering the firewall, and routes the raw data back to the application. This worked! And the website is finally live and i am about to ship the project!
Ships:
This is Orbit Lens, a real-time 3D satellite tracking website built using vanilla JavaScript and Three.js. It tracks over 16,000 live space objects around earth using real-time data from CelesTrak. It has many features including 3d and 2d orbit tracking, 3d models of select satellites (ISS, Terra, HST, and Aqua). It also includes a filtering feature where you can filter satellites based on specific categories Before testing this project, it is important to know some stuff: You will have the best experience if you access this through a laptop or desktop Sometimes, the api maybe down or is not responding to requests so please keep in mind that if you see an alert saying API not responding, it is out of the website’s hands and it an error outside of my control. That’s it. Thank you for testing this project and hope you like it :)...

I also implemented protocol versioning, which each brush specifies in its manufacturer data so the host knows what commands/values are available for the brush. In most cases, the newer the brush model (especially in the iO series of brushes), the higher the protocol, resulting in more available commands / data values to read from. I’ve also added the first incoming command: batteryLevel ! This method requests battery data from the brush, and depending on the protocol version of your brush, you’ll be able to view info like the battery percentage, estimated runtime, and even the technical specifications of the battery (like voltage, current, temperature, etc). From here on, all I’ll be doing is adding more support for commands!
I finished adding some more commands: deviceState which tells you what “state” the brush is in (running, idle, charging, etc), buttonState which allows you to subscribe to button events and notifies you when the power or mode button was pressed, and brushingTime which allows you to view the live stopwatch as you brush your teeth. I built a simple demo script to give you all a visual example of how these can be used!
I’ve finally finished working on the documentation! I also added a commands table in the README.md which lists all of the current commands and a link to their designated Markdown page. I’m preparing to publish it to npm.js now!
I spent some time cleaning up the package.json and implementing some bug fixes like adding reads and subscriptions to a queue (since before it would send them at the same time and crash the brush occasionally). Some newer brushes also require an “unlock code” to use the Bluetooth API, so I implemented that too! The first version is now live on npm.js!
I made a quick demonstration video and added some example scripts to the project!
Ships:
I built a Node.js library for bidirectional Bluetooth communication with Oral-B smart toothbrushes, without needing the app! The most challenging part was definitely reverse engineering the Bluetooth characteristic logic in the Oral-B Android app using jadx. Since testing out this project may be difficult for obvious reasons (not too many people have an overpriced smart toothbrush xD), the demo link will bring you to a sample demo video of how it works!...
