The term “Charileplexing” is not a familiar one for many electronics hobbyists. Charlieplexing is a technique proposed in early 1995 by Charlie Allen (at Maxim Integrated) for driving a multiplexed ...
This open-source Enigma replica by the folks at [ST-Geotronics] is simply stunning. They drew their inspiration from a hilarious build we saw a few years ago that hacked a children’s toy into an ...
What’s the smallest RGB LED cube? A 1x1x1 cube is easy, but it’s a stupid joke and we’ve heard it before. No, to build the smallest LED cube, you’ll have to stuff 64 RGB LEDs into a cubic inch, like ...
Charlieplexing. The verb is an electronics technique apparently named after one Charlie Allen, an engineer at Maxim. It involves minimising the use of I/O pins on a microcontroller to drive a maximum ...
A few articles have recently appeared describing novel ways to increase the number of LEDs a microprocessor can drive with a limited number of pins (Reference 1). The standard multiplexing technique ...
