I have started a call for participation on http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1239034920 and http://www.freeduino.de/de/blogs/gatonero/aufruf-zur-teilnahme-der-froscon-2009. In Germany Arduino is until today very unknown. I couldn't activate participators for a lecture, because the German community is still very small.I'm really new to Arduino but I'm very much exited of it. Since several years I'm using and loving open source software and did some translations in the linux environment. Open hardware like the Arduino caused me to learn C/C++ after several attempts without any success.I would like to spread the idea of Arduino and do my part to found a community in Germany. I don't know exactly what a lightning talk is, but it seems too be nice for an introduction of Arduino.I hope to activate two or more colleges for this event.
