After this tedious step, he designed a PCB that hosts an Arduino Nano to accept input, two MCP23017 GPIO expanders to give it enough outputs, and CD4066BE CMOS switches to trigger the connections.

I was filming at the US Army's Mountain Warfare School in Jericho, Vermont, and one of the soldiers had just put an avalanche transceiver on me. It would tell people where I was if I got buried in ...
