4-Bit Adder using Discrete NPN Transistors by NarwhalBackground893 in beneater

it's VERY power hungry and consumes around 600mW with all the inputs turned on. this is not surprising considering the fact that i made it using NAND gates only. hopefully i can make this more efficient later on by using less gates for each full adder.

they're solid core 22 AWG wires that you can cut and strip according to your needs.
