@Tech_girlll 1. Don’t be the tragic hero
2. Deliver actual value, not another refactor

Thanksgiving night KiCad goblin mode: designed a tiny dual IR encoder board for servo / motor tests and sent it to #JLCPCB.

@gregisenberg I have a hunch that they will come back.

[Aaron Qian @aq1018]

@luke_pighetti Give me some solid metrics and I’ll believe you.
