great, thank you very much!. Meanwhile Mr.Janssen was so kind to answer quickly to my request at Elektor Forum. He is a very friendly and helpful person and think that the pople from Elektor would support a video of this session, but he didn't know were it will be stored. We were faster than him ;-). Thx Chris again! I sent him the Link to support other requester too!
I will watch the video now :-) Good luck with your projects!
