2023-06-20 (Tu) KeyBoardolier Repairs

Some of the most important notes I kept about this keyboard were ways to improve the next iteration so problems, like repairs, would be simple. One key on the right side did not work, and I could feel the cold solder joint. Three keys on the left stopped responding after I installed the offhand buttons, probably due to yanking a diode lead off its spot with the wires I pulled through.

I modified the program to turn on an LED whenever I held a key so I could test all my connections. I opened the covers, which took 12 nuts and 8 bolts. Excessive hardware was another issue I noted. I found the problem, a dislodged diode, and repaired the joint.

The right side was easier because I did not have to remove any protective hardware. My soldering iron could reach the cold joint without burning the surrounding material. I tested all the buttons with the LED feedback, even the offhand keys, then sealed it up. Hopefully, for the last time.
