PCBs / Panels for sale

Over the past several years i made PCBs and Panels for quite a few Thomas Henry DIY projects, as well as for my own fonitronik DIY projects.
These are available via retailers, in general i don't have any stock and won't sell directly.

If something is out of stock just bug the retailers to re-stock.

Thomas Henry Projects

Over the past  couple of years i had the privilege and pleasure to publish PCBs and front panels for several Thomas henry designs. Thomas Henry contributed quite a lot great designs to the synth-DIY community. He published several books on the same topic. The designs are either making use of ICs that have not been used this way before or try to use easily available common parts. Either way the designs are unique and the results are great.

To the right you will find my documentations for the PCBs i provided for his projects so far.

If not provided in my documents the original schematics and BOMs can be found in the Thomas Henry subforum at electro-music.com.
