In the spirit of cluster computing, the Turing Pi Clusterboard brings another dimension in the world of cluster computing for makers and hackers. The Pimoroni’s Cluster HAT gave us the power to connect up to 4 Raspberry Pi Zeros to create a cluster computer, the MiniNodes' 5 Node...

Controlling LED brightness through digital potentiometer and a LED driver from ON Semiconductor. Light-emitting diodes (LEDs) require a regulated current, and their brightness is proportional to the current that flows through them. Some LED drivers use an external resistor to set the...

Josh built this 6CY7 dual triode valve amplifier: I’ve always wanted to know what the “tube magic” was all about. There is much opinion in the science of music production, probably because music and its perception is highly personal and subjective. Ive always imagined that since...

I've seen a few other people experimenting with making custom LED displays using discrete LEDs so I thought I'd like to take my own stab at it. by sjm4306 @ hackaday.io TinyLED 7-Segment Displays -...

Cluster Computing brings the power of multiple computing units to serve one single purpose. If you are looking for some performance boost and you got yourself some freely available computing units, cluster computing might be what you need. Unfortunately, building yourself one is not that...

This counter is made only from an ATtiny13 and LED diodes. Did you ever need a cheap and simple (with one digit only) pulse counter? This is the maximum optimization and simplification. Thanks to Charlie Allen. The Cheapest and Simplest Pulse Counter -...
