Armed with a functional inverter, the next step was an OR gate. By combining NOT and OR gates, you can easily make a NAND gate, an AND gate, a NOR gate, and any other logic you can dream up.

1 NAND inverting gate and AND non-inverting gate Standard ... So, It would be inefficient to use an inverter when the inversion can be optimized away in the logic by using an inverting logic function ...

Here’s how an inverter works in this computer ... ping-pong balls can perform computation could seek our guide Make Logic Gates Out Of (Almost) Anything. And finally, a Hackaday salute to ...
