mTroll MIDI controller hardware parts list

These are the main parts I used in my foot controller. Since you build your own hardware, it is totally customizable. LED color, switch configuration, switches with audible positive feedback, silent switches, table top operation, etc. Since this is built around the monome logic kit, you don't need to code the firmware or flash anything.

Common to all versions:
monome logic kit and more info (parts list)
FrontX panel mount USB cable
Radio Shack 1/4" TSR jacks (for expression pedals)

Version 1 (2007):
Ground Control Pro chassis
P26A-1D-BL Carling foot switches (clickless, momentary switches)
Jameco T1 3/4 Blue LEDs (these are almost too bright)
Radio Shack panel mount LED holders

Version 2 removed the LED holders and replaced the LEDs with a 3-wire RGB LED strip (2020):
5V Addressable RGB LED Strip WS2812B (WS2811)

Version 3 replaced the chassis/case, LEDs and switches (2026):
Expanded case fabricated at SendCutSend
P26A-1D-RND-MTL Carling switches (metal momentary switches)
Adafruit Breadboard-friendly RGB Smart NeoPixels
