As an electronics rookie, one of the first things they tell you when they teach you about logic gates is, “You can make everything from a combination of NAND gates”. There usually follows a ...

What’s the weirdest computer you can think of? This one’s weirder. [Dr. Cockroach] figured out a way to create an inverting NOT gate from just one LED and two resistors (one being a photo-resistor).

The screen of NandGame looks like this. We will install a NAND gate on the purple board and build a new circuit. The explanation of the circuit to be assembled is written on the left. The language can ...
