After the wild success of the first workshop, it was time to make another one. Location and team remained the same: Marius and me had a room in Krikragaa HQ (in Pilies dirbtuves, Klaipeda) at our disposal. This time we have focused more on manufacturing process and simplified the circuit complexity as much as possible. Components: coin battery and flashing RGB LED. Skills taught: PCB preparation. Goal: make a flashing badge.
