30 Key Keyboard

I had some spare parts around and always wanted to experiment with a 30 key keyboard. So here we are. ###Parts + 1 [KB2040](https://www.adafruit.com/product/5302/ "KB2040") + 30 MX switches + 30 MX keycaps + 30 [diodes](https://www.amazon.com/BOJACK-Switching-IN4148-Electronic-Silicon/dp/B07Q4F3Y5W/ref=sr_1_1_sspa?crid=2ODR6QNWGS6UG&keywords=1n4148+diode&qid=1672705459&sprefix=1n4%2Caps%2C170&sr=8-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUExOFU3WkdSUzJGSURBJmVuY3J5cHRlZElkPUEwMjE0MjA4M0JBUkkyUUdMTlRURSZlbmNyeXB0ZWRBZElkPUEwMzY2ODU4MVlQWkEwMFNRVjVQNCZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=) + 24-gauge solid core wire + 11 - M2 4mm knurled nuts and associated bolts + 2 - M3 4mm knurled nuts and associated bolts + [socket pins](https://www.amazon.com/gp/product/B07W5HBRMP/ref=ox_sc_act_title_5?smid=A286O29JJYZD4N&psc=1) for KB2040 ###Optional + 30 [Amoeba Royales](https://github.com/mtl/keyboard-pcbs/tree/master/amoeba-royale "Amoeba Royales") As with any hand wire keyboard, it's helpful to understand the theory behind how a keyboard works. There are a lot of materials out there so Google away. I used socket pins in the opposite direction, so the "pin" is soldered to the KB2040 and I push in the column and row wires into the socket side. I also made use of some amoeba royales to make it hot swappable. They are optional, they can help with the wiring to keep it at a lower profile and help give it a cleaner look. I then programmed with QMK with my preferences of layers, combos, tap dances, etc. There are a lot of materials out there for QMK too, so Google away again. Works great as is, but as always have some things I'd do differently for a v2 + create a wire channel to connect the T to Y for row 1 + create a wire channel to connect the G to H for row 2
