For a workshop during our weekly HackJam open night, Sadale brought electronics kits that he designed and got produced. We followed the instructions and were rewarded with a circuit that can count up to three: You press a button, and the next LED will light up. There are three LEDs, and there is a reset button. One of us tried to add auto-reset as an additional feature.
Sadale originally created the kits for Toki Pona Day 2021. Toki Pona is an artificial human language. Fortunately for the rest of us, the instructions did have an English translation.
