Decided to share an older "project" of mine - ms sculpt wireless to wired conversion (also, it runs qmk, so we get all its features). A sensible person would order a custom pcb (such projects exist on the web, take a look if you're interested), but I went with removing all the components except from the ribbon cable connector, sending the PCB smooth, gluing a piece of discount card to isolate the traces, gluing a Chinese rp2040 on top, and wiring all the necessary traces to it. No, it wasn't fun. Yes, it works.
Bonus: when I disassembled it now I found out the type-c wasn't soldered well and decided to separate from the board:

So, here we go: using phone as a poor man's microscope (note: also, still works)

The end result kinda doesn't give it out, so whatever (insert your frontend -- backend jokes here)
