Stelios's Place

A place for thoughts and ideas


   Just a few projects I'm working on from time to time. I have tried to describe the project in a DIY manner. Sketches, plans, circuits and code are freely available for anyone willing to build one of the projects. You can always sent me an email to ask me anything if you have problems replicating the projects.
