It's been a while since the last time I've updated this project. The reason is that I am waiting for the boards to be ready so I can assemble them. In the meanwhile I have translated the user manual for English language. Here is a link for the manual.

AT26-Chuck User Manual (draft)

The 'draft' status of the manual refers to the pictures, that are still from the previous format of the board (this was one a commercial product).
