"Don't shoot!"
This is my Arc Raiders Anvil build. I got the main 3D model from Thingiverse here but you can find my remix for the files here. In order to kit this Anvil out with sounds and lights, I used a Pi Pico for the main board, a 3W Class D MAX98357A amp, a 3.7-volt battery, a simple switch, three NeoPixel LEDs, and a speaker. The Pi Pico runs CircuitPython, and the code I wrote for this project can be copied from here. Forewarning: the code is pretty sloppy and not commented out.
