Finished my second prototype today:
124 ligtht blue box switches ( this one is my home board, so clicky is not a problem)
Both of my boards:
The top one is my original build - Hako true switches and MT3 Suswatari, green backlight meant for the office (the blue F-keys and blanks are row one SA keys)
The bottom is my new home buld - Box light blue with MT3 /dev/TTT, amber backlight. The extra F-keys are from the extras kit.
Both feature my custom QMK buld that always asserts num lock, so I can re-use the key.
Edit: I had some issues with the keyboard resetting while plugged into a switch if I turn the yellow backlight up to high. Running from the PC is fine. I just checked, and with a 100 Ohm resistor, the green 1.8mm leds draw about 7.3 mA while the yellow draw about 11.3mA. So over 124 leds, that gives a draw of about 900 mA for green instead of 1400 mA for Yellow. So if you are on the fence between the two colors, I would go with green.
