Learning about transistors

Sometime before the Circuitpython fiasco, I watched the below video about transistors to understand the mystery on this board:

The main frames I want to point out are diagrams of a diode and NPN transistor:

I noticed that the transistor looked like 2 diodes put together. I looked into it and found symbols like the below:

Since matrix scanners only scan one row/column at a time, it's likely safe to assume that the designers of the WK-50 used transistors as alternatives to dual diodes (e.g. BAT54C). 

I tried the KMK starter code and the keyboard matrix is configured as Row to Col.

Creating the layout in pog

Turns out pog can install/update KMK, which is nice.

Since I gave the board useful pinnames, it was barely an inconvenience to set up:

Then I got the ChordMap, moved the keys in the layout area to approximate the keyboard whilst still looking tidy and added the encoder pins:

I also needed to download the neopixel library and put it in the lib folder:
