After developing relay based logic gates and designing 1 bit full adder made from relays, the challenge was to link a few of these together to create a relay based binary adder. The overall objective was to create a relay based adder that could handle calculations of at least a moderately interesting size. A 4 […]

# Relay Full Adder Circuit

Having designed some logic gates using relays, I had the foundations of doing simple math with a pure relay circuit. This is where the adder comes into play. To understand how adders work you really have to start with a brief discussion of base 2 vs base 10 mathematics. Everybody should be familiar with base […]

# Creating Relay Logic Gates

I am not a computer scientist. Nor have I really had any CS courses. Far from it. I hold two degrees in literature and literary theory. So, when I started to wonder how computers work (since I use them every day!) I had to go about teaching myself. While I have some experience with contemporary programming […]
