Finally got my hands on "Penny" last weekend, here is a result: https://www.youtube.com/watch?v=iT2JZWRhM9s

ESP32 dev board a lil-bit wider for original design but it's OK. Will fork project and publish my changes soon, after "polishing" code (I hope so).

P.S. By the way, we've already met on habr. I already received PCBs but not CPUs (from ali, for original design). But I'm thinking about adopt RPi Zero W (got a couple for the sale price, $5 each).
