TV-B-Gone is pure subversive fun. If you don’t know it, it was invented by Mitch Altman and it is a universal TV remote control with a single button, the power button. You can only switch TVs off. No longer dumb advertisements everywhere you go. Just switch them off. Extra portions of fun in a MediaMarkt.
Just [...]

Back in March I published my first instructable called Programmable LED. The idea was simple, have a device that is able to record and play back light sequences. Light sequences are recorded with an LDR, a light dependent resistor and played back with an LED.
After a while some users at Instructables began to rebuild, modify [...]

DIY Tengu on a breadboard

When I first saw Crispin Jones Tengu, I was sure, I must have one. If you don’t know tengu and don’t want to follow the link, it’s a small face, made of LEDs, that reacts to music and sound.
It did not take long until I decided to clone this funny little device. All it needs [...]

Synchronizing Fireflies
May 11th, 2007 · 15 Comments · avr, instructable, led, simulation
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 rule behind this is very simple. All fireflies have nearly the same frequency for their flashing, but [...]

Programmable LED
May 9th, 2007 · 10 Comments · avr, instructable, led
Inspired by various LED Throwies, blinking LEDs and similar instructables I wanted to do my version of an LED controlled by a microcontroller.
The idea is to make the LED blinking sequence reprogrammable. This reprogramming can be done with light and shadow, e.g. you could use your flashlight.
How is it done?
It consists of an LDR, an [...]

LED Clock
May 5th, 2007 · 9 Comments · avr, led
So this is my approach of an LED clock. There are zillions of LED clocks out there. Mine is some kind of retro and minimalistic version. It consists of
AVR ATmega8, 8 Kb, 4.096 MHz
Everlight 2.3″, LED Matrix, 8×5 LEDs
some resistors, capacitors and a quarz
optional serial connection for configuration
The LED matrix is used in landscape mode, [...]
