2023-05-28 (Su) KeyBoardolier Care Bear keyboard rewired

I soldered six 10KΩ pulldown resistors to the column inputs and linked their common side by bending one lead over its neighbor. I added Kapton tape to the leads overhanging the keyswitches and Arduino where it might touch the metal case. I made a micro USB extension from the Arduino port to a socket on the top of the keyboard to keep enough clearance to the enclosure.
Pulldown resistors and Kapton tape

My makeshift extension worked because I could read serial data from the Arduino through the same connection. My faulty diode arrangement meant I could only read one key in each column, but that would be fine for a macro keyboard. I attached keycaps from a selection of whimsical summer-themed caps and plain black.
