Recently, I wanted to build a Sleepy-LED Eye as an add-on indicator for a small personal project. My idea is a near-replica of the iconic breathing pattern used for the “sleep” indicator in Apple ...
In this project eight LEDs are connected to PORTC of a PIC18F452-type microcontroller, and the microcontroller is operated from a 4MHz resonator. When power is applied to the microcontroller (or when ...
The LM3914 LED bar graph driver was an amazing chip back in the day. Along with the LM3915, its logarithmic cousin, these chips gave a modern look to projects, allowing dancing LEDs to stand in for a ...
An AVR chip is used to design a great programmable LED which provides fun and a good building block for playing with collective behaviors. An AVR chip is used to design a great programmable LED which ...
While regular Hackaday readers already know how to blink a LED with a microcontroller and have moved onto slightly more challenging projects such as solving the Navier-Stokes equations in 6502 ...

Someone built a system that lets them "pour" LED pixels from a display into and out of their monitor
All the fun of fluid dynamics without any of the real-world mess.
