I am a systems engineer that had worked so far for more than 30 years in academia and the communications industry. Now I have time to care about my hobbies and show the outcome to the public.

I have recently started to describe in this page the outcomes of my hobbies which are embedded electronics (schematics, mechanics, software), especially audio projects, quadrocopter development and finally also mobile communication (theory, concepts, algorithms etc.). All of this requires some mathematics …

Unfortunately most of the contributions are in its very infancy …

In the links you can find some final results and project descriptions on GitHub.

… so stay tuned for what will come within the next weeks, months and years …

Have fun in browsing this site and contact me if you should have any questions on my projects. I have some time left to answer …
