3-day streak
I love wasting my money

Got some more progress done on the car.
I'm using Arduino IDE to debug some steering stuff for self driving RC car. LOOK AT THIS POTENTIOMETER GRAPH OOOOOOOOH BABY

Well at least I don't have to buy batteries now

I 3D printed a mock-up of the lower pipe flange design for my #the-trail project. Here's hoping I get in!

modelling a yagi antenna based off of this. almost done!

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 👀

I finally made physics go brrrrrr woot woot

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!
