Relay Adder

Media Summary: Just in time to be a few days late to Pi Day, I built a machine that computes the digits of pi with In this video we learn about the basic theory of binary adders and I build and test the PCB for my 16-bit NOTE: The schematics incorrectly show the NPN transistors in reverse, with collector / emitter swapped. This is my first attempt at ...
