All around electronics, software, mechanics, computer stuff and other things you can find here:

documentation / description of my projects
tutorials - from programming to "bomb" building
the engineering / tinkering blog (in German); mostly about all kinds of technical topics
other stuff (old projects/tutorials, code snippets, and the like)

By the way, I am Cypax, technics nerd and hobbyist. And on these pages I describe all the oddities I disassembled, analyzed, modified, repaired, programmed, broke or constructed.

More information about me can be found in the Info and, if there are any more questions, here are the FAQ.
