@awdev – Hack Club Scrapbook

Mon, Aug 26

My Aviary project is a study in aerodynamics. This is a pretty long overdue scrapbook but I got lift simulation working with the airfoil's angle of attack! Github: github.com/aaronw-dev/Aviary Specific Commit

I forgot to scrapbook this LOL, but I did a hackathon with my buddy @IngeniousAlbert . We created a Progressive Web App (PWA) called Codex. Website: codex.awdev.codes (it's a mobile site meant to be installed on mobile devices) Github: github.com/aaronw-dev/codex Devpost: devpost.com/software/codex-qwf8rg

After a long, long while, and lots of indecisiveness, #forge-dev Motherboard version 0.0.1 Alpha is ready for production! @ArnnavKudale and I will be manufacturing our prototypes using our Onboard grants. I can't wait to get 'em! Github: github.com/EmperorNumerius/Forge Website: forge.hackclub.com

I have been working on the Hack Club Shop (shop.awdev.codes) for the past while. I'd like to share that I have successfully implemented Shopify integration through my backend and product pages that are dynamically served through HTML templating.

For the past few months, I've been working on this. It's called Aviary, and it's a C# app that simulates different airfoils based on a standard file format. Currently the airfoils are hardcoded into the compiled program, but this is for internal use so I don't really care. You can take a look at the source code here: github.com/aaronw-dev/Aviary

I haven't posted in a while, but I've been starting to self-learn aerospace engineering. I wrote a little website here (please note that it works horribly on non-16:9 screens) that can parse airfoils from CSV and show them on a canvas. However, I realized that browser JS is the most horrible language to do what is basically CFD in, so I've been starting to move the code to C# and Raylib. Left image is my new C# version, and the right image is the old web version.

Got the buck converters working and powering the H bridge and microcontroller. Beeg battery with insanely high discharge rate. I've got some firmware on the microcontroller working with the H bridge, so it's almost time for some self-driving shenanigans. Just need to finish mounting my sensors. And I also burned like 5 of those stupid LEDs out yesterday. BRO THEY CAN'T EVEN RUN NICELY ON A DEAD 1S LIPO UGHHHHHHHHHHH

Custom 3D printed mount for my ultrasonic distance sensors. Brass inserts to bolt into the chassis.

Got my buck converters working! Voltage adjustments are in place. This is a 4S 3Ah LiPo with an XT60 connector. It connects the buck converters in parallel, meaning they don't have any voltage diminishment and extra current draw on one bus doesn't affect the other device. 12 volts from the buck converters is going to the H-bridge motor driver and 5 volts is going to the Arduino Mega (not pictured). Hope you guys like it!

Got some boards for a project. We have 5 ultrasonic distance sensors and 2 adjustable buck converters with voltage displays. Stay tuned for more developments soon 👀

Got some basic collision working finally. If you look closely, the bounces downhill go further than the bounces uphill. The little red sticks coming off each face are the normal vectors.

I found out how to calculate the normal vector of a line and wrote my own algorithm to normalize it within (-1, 1). It may not be amazing or look great, but it's the small victories that count. Next step: getting this to work with a physics system.

I am beginning my improvements on my JS physics engine, first with bounces. Now to implement surfaces with normals and normal reflections. This is quite fun!

I did a basic implementation of gravitational physics in one HTML file. I made it in 1 hour, and you can try it out here: aaronw-dev.github.io/physics-basics I will work to improve it, but for the time being, I think it's pretty decent.

Soldered two of my motors to the ESC. Did a test with battery, and it works amazingly! I got the du-du-du sound! Now to wait for the ESP32 (yes that's my FCU) and props to arrive.

I bought the HC-05 Bluetooth module a very long time ago and I recently dug it up in preparation for the hackathon. Just making sure it works, it clearly does!
