Made an 8-bit adder entirely out of cake, comparators, and trapdoors! Just eat the cakes to input the 1s and 0s, and then start the calculation by eating the start cake! I know it's a bit on the larger side but that's just a side effect from eating so much cake..

It's an 8-bit rca, and the last photo shows the result of 01111011+11101010=101100101 (123+234=357).

Bon appetit 🎂
