Ce bout de code permet de générer du son en stéréo en utilisant deux sorties PWM d'un ATMEGA644.

This page on Flex Solar Cells website displays very useful t

EAGLE is a professional software for designing PCBs. It's also pretty useful to create schematics. It is multi-platform and there is a very good "light" freeware version. Get it here:

Yesterday we met Bartaku, an artist who works at foam right next door to iMAL. For one year, Bartaku has carried on a huge research on solar energy.

There is a sleep mode available on Atmega chips, which makes them use only 10nA. See the following post on the Arduino website: http://www.arduino.cc/playground/Learning/ArduinoSleepCode

A website that containts a set of methods / libs / tools for ATtiny programming. Needs further investigations...

For the record, I found two examples of easy-to-build circuits for radio transmission:

• 1.5 V Transmitter
• FM transmitter

Stirling engines are able to produce energy using heat.

I managed to compile and upload AVR programs on my Mac using different tools: AVR-GCC, AVRdude and my AVRISP2 interface. I wrote a set of instructions for the Electronix people, see:
