Here is an experiment with an 8×8 LED matrix, driven by a MAX7219 IC, controlled through an Arduino micro-controller board. A custom PCB has been made by Tan from DinoTech to tidy up all the wires connecting the LED matrix and the IC. It comes with a separate 12V power supply, in order not to drain everything from the Arduino board.[more]

This is a low power voltmeter circuit that can be used with alternative energy systems that run on 12 and 24 volt batteries. The voltmeter is an expanded scale type that indicates small voltage steps over the 10 to 16 volt range for 12 volt batteries and over the 22 to 32 volt range for 24 volt batteries. Power consumption can be as low as 14mw when operated from 12V and 160mw when operated from 24V.[more]

This circuit simulates fireflies with small microcontrollers. Note that every firefly acts completely autonomously, it is not a preprogrammed pattern. It is a self organizing system.
This is a remake of the fireflies which I did a year ago. I was always fascinated by the emergence of patterns. One I like most is the synchronization of hundreds or thousands of fireflies. First they flash randomly but after some time and influencing each other, they flash in sync.

The goal of this project is to provide as complete of a resource as possible for people interested in getting into creating artwork incorporating LED lighting. A secondary goal is to provide basic information on general engineering practices for creating standalone LED art.[more]

This is a LED art project with 95 RGB LEDs arranged in a 3D cylinder shape control with a microcontroller-based driver circuit. The LEDs are individually addressable, and when you power it on, the software cycles through a series of animations, e.g. various moving rainbowy patterns, “rain”, “fireworks”, and so on. It doesn’t serve much of a purpose but it is kind of cool to look at. The hardware and software are open source, so feel free to use/copy/extend whatever you find here. [more]
