Keyboarding ain't easy?? What not to do when building a keyboard!!
summary
Build attempt uses DSA Dark Magical Girl keycaps on a custom PCB that never quite works: wrong KiCad drill and trace settings force a full reroute, hand-soldering tiny SMD parts fails despite stencils, and choosing individual four‑wire LEDs instead of ws2812 / neopixels creates routing chaos. Debugging uses a STM32 Nucleo dev board, a logic analyzer, and eventually rewritten Rust firmware, but many LEDs and USB drivers never behave and the project ends by buying a commercial keyboard.
