DIY Mechanical Number Pad

Wanted a number pad to match my Atomic keyboard, had a top & bottom plates cut from Lasergist and wired myself.

I tried hand wiring switches and LEDs, but was a disaster. Went with Cherry MX breakouts from SparkFun electronics. Used a Teensy controller with custom layout written using QMK.fm

Backplate has hole for reset

Sides made of Lego
