I joined later but I never read anything about such a list. On some forums, you are asked, if you agree, to put your location (city) on a map. It might be interesting for a teacher or a hobbyist to share ideas and design together some hardware with a "neighbour". Still, you are not completly alone and can post on the forum to receive some help.
Thanks for the answers, I do try to find a fellow Picaxer who lives in Elburg, and on a evening he was bussy to install a lighting artwork based on a 40x2, but it dit not succeed! So now i try to find him to offer expertise and some usefil picaxe things I made in my past sa special effect for film and theater.
