23C3: Blinkenlights

29.12.2006 2:19

The center of attention in the Art & Beauty section of the Congress are again various things made out of blinking LED diodes. This year people from the Lochraster joined people from the Blinkenlights project which I remember from the 21C3.

Here's the newest invention from the Blinkenlights project: the Pocketlights. This beta version disintegrates when picked up but the final version should enable you to bring LED displays where none thought possible :).


This is a complicated simulation of one of the simplest toys. Unfortunately you can't see how it works from this (terrible) still picture. It has a two-axis accelerometer and simulates a tiny ball placed on a flat surface. The position of the ball is indicated by a lit led on the dot-matrix display. The final effect is that you can move the pixel by tilting the circuit.

This is Borg 3D. I've seen its simpler predecessor on 21C3. It's basically a 3D display made of LEDs in a metal wire matrix with 8x8x8 pixels. It's controlled by an Atmega microcontroller which drives the display with the help of some multiplexing circuitry (multiplexer "rows" are connected to 8 horizontal planes of LEDs and "columns" are connected to 64 vertical columns).
