Welcome to leyanda.de!

My name is Andreas Fiessler, electrical engineer and passionate hobbyist in my spare time. Beside my regular job as a research engineer my interests include all kinds of electronics, microcontroller, robotics, light effects, amateur radio (DH7AF) and much more.

This website is an attempt to collect and publish my previous and upcoming work on various DIY projects - or at least some of them. 

If possible, I try to provide more or less detailed instructions, source code, and schematics so you can use it as a basis for your own work.

I am always happy to hear about your ideas, comments or questions regarding my projects.

One exception: please do not try to use me as a free of charge consultant for general questions which can be answered by brief research (e.g. how to use a microcontroller).
