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 ...

System-on-chip (SoC) designs are becoming more and more complex, by whatever means you measure it: power domains, gate count, packing densities, heat dissipation capacities, etc. At such high packing ...

We’ve seen a few 1-D pong games recently, and they’ve all be controlled using microcontrollers. Inspired by some of these hacks, [mischka] built the monoPong using a handful of logic chips. The ...
