Here is a simple circuit which helps to know how SR Flip Flop can be designed using NOR gate. In the circuit diagram, there are two input terminals S and R. The SR Flip Flop is one of the fundamental ...
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).
