Announcing a new Quick Video: A Full Adder

When we used NPN transistors to build our logic gates, it implies they can be used for building bigger things. In this video I’ve built a full 1 bit adder from our second Introduction video, entirely from discrete transistors.

Build 8 of these–and you have an 8-bit adder.

The show notes include the complete circuit diagram.

So here’s the video.

And thanks for watching.
