Often, it becomes necessary to interface an existing or new 5V AVR / PIC / MCU project to new devices that use 3.3V logic, like memory cards, sim cards, etc. Described here is a circuit that converts ...

A flip-flop is one of the most basic digital electronic circuits. It can most easily be built from just two transistors, although they can and have been built out of vacuum tubes, NAND and NOR gates, ...

An engineer has assembled the most complex logic circuit yet assembled in a single bacterium. The logic circuit, in which genes and the molecules that turn the genes on or off function as logic gates, ...

Here at Hackaday, we pride ourselves on bringing you the very freshest of hacks. But that doesn’t mean we catch all the good stuff the first time around, and occasionally we get a tip on an older ...
