Protogen Head part 8: PCBs, head frames, and printers

by



I want to build a Protogen head using a frame I’m sourcing elsewhere and electronics and exterior finishing by myself. This is part 8 of the series, where I go over several things that have arrived in the last few weeks, including the PCBs that were designed in the last part.

I’m writing the bulk of the code for this project myself, using TinyGo.
Main code: https://github.com/ajanata/gotogen
Simulator: https://github.com/ajanata/gotogen-simulator
Text buffer: https://github.com/ajanata/textbuf
LED panel driver: https://github.com/ajanata/aykevl-things/tree/matrixportal-hacks
I2C DMA driver + other fixes https://github.com/ajanata/tinygo-drivers/tree/mine
