This is very simple and useful project which gives an idea about how to build the simple logic gates i.e. AND, OR & NOT gates using one of the universal gates – NAND Gate. This is very simple and ...

Using just two NAND or inverter gates its possible to build a D type (or ‘toggle’) flip-flop with a push-button input. At power-up the output of gate N2 is at a logical ‘1’, ensuring that transistor T2 ...

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 ...

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).

Spin waves can be applied to low-power multi-input-multi-output logic gates based on its wave functionality realized without electron travelling. In particular, spin waves propagating in yttrium iron ...
