Electronics
In my younger years I spent almost al my time building things with Lego Technics. These were mainly
elevators and robots. Since this was in the pre-mindstorms years, I had to create my own computer interface
and low-level software. This is where I learned the basics for building robots.Later I became more and more interested in electronics. I first took apart various machines, but I was not able to assemble them again. This way I learned a lot about TV's, videorecorders, old computers and stereo equipment. Later I discoverd how to repair these machines and this was even my job for a few years until I had too many requests and I took too much time to fix all those machines.
In the meantime, I also learned how to design and build machines. First projects were a TV pattern generator, an amplifier and a CD player from Elektor.
