Welcome
This page is intended to keep my little projects a bit better documented. I'm always losing my notes and some months later I can't follow my own thoughts anymore. 
But of course I'll be happy if someone is interested in something or if this documentation will even be helpful for other hobbyists. If you have any comments don't be shy and send me an e-mail. I'm just a hobbyist in electronics so there is much room for improvement.
