Hi Sascha

Thanks for the kind words, I hope you like the Zagreb chess pieces as they where a present from my two sons this Christmas

It uses the Stockfish engine and the project software was written by Matt Shannon from America. The board is press sensory using tactile momentary switches under a semi rigid plastic chess board.

Unfortunately, Matt didn't completely finish this project because of pressure at work and therefore didn't release his software publicly. There are a few features still missing but luckily because I worked with him on the project, I was able to build a fully working prototype that I really like minus the missing features.

Here's a link to Matt's site. Sish - Computer Interfacing DIY Chessboards
