The projects presented here are currently being "worked on". This means that these projects are not yet finished, but will be completed in the foreseeable future. Since the project description is only written afterwards, it often looks as if a project is at a standstill. I can assure you that this is not the case. If you are interested, you are welcome to ask about the status of the project.

These projects were built and tested by me. I have tried to document them as comprehensibly as possible. Reconstruction should not be a problem. The complete project documents are available on request. Boards or complete modules are available in my shop. If you need further information, please just mail me.
