One possibility for extending wire lengths is to use a single pixel as a signal booster/repeater every so often. Say you want to have a display 50 feet from the controller, just wire in a single pixel every 15-20 feet along that cable. Each pixel regenerates the clock and data signals so you should be good then for another 20 feet or so.monkey141 said:Thanks guys, I appreciate the help. I ordered two different kinds, the larger 30mm circles and the smaller m5 size. I am not crazy about the quality of either like you have suggested, but I think I am going to give a go at the 30mm circles, and I am trying to plan everything out now. I will be sure to post back with what I end up with. I had started out earlier this year, building my own as well and then abandoned it when I found out about some of these, but clearly the quality (and long term stability) can be questioned.
My approach has been to build a controller that's inexpensive enough that I can put a separate controller wherever I need one. I will probably have 6-8 separate pixel controllers in my display this year, hoping for 2000+ pixels.
