Building a Relay-Powered Pi Machine

Just in time to be a few days late to Pi Day, I built a machine that computes the digits of pi with relays.

Congratulations to Matt Parker and his team of human computers for calculating 139 digits of pi by hand. My machine hasn't even come close to that.

This year man has beaten the machines...
