first electronics project. I found this last second so i couldnt do much more than this because of the time constraint. Made in 5~ hours. I have access to a 3d printer and will print the case myself (possibly iterating on it to make it look better.)

Parts list / BOM:
*Seeed XIAO RP2040 1x505TL link
*9x MX-Style switches 450-500TL (this was the only listing i found and it sells 10 so price is approximated.) link.
*EC11 Rotary encoder 1x32TL link
*9x Blank DSA keycaps (wasnt able to find a listing on this one, i can source it myself when i find it.))
*9x SK6812 MINI-E LEDs 35TL~ (same with the switches, the only listing i could find sold 10 so approximate price.) link
*9x Through-hole 1N4148 Diodes 9x0,41 ,3,67TL link

Total: 1025TL~ = 24~ US dollars
