Arduino ☛ This DIY experimental reactor harnesses the Birkeland-Eyde process
Creating an electrical arc isn’t very difficult, but controlling it is more challenging. For that reason, Marb used an Arduino UNO Rev3 to oversee his DIY reactor. Through a breakout shield, the Arduino controls the flow of power to the arc electrodes. That requires a large power supply, transformers, and a boost converter.
