[QUOTE="TerryK, post: 117835, member: 32169"] A rather poor and ugly example but... This is a Gilbert Engineering rabbit I had out for Easter. Total pixels 268 and for better or worse, power injected at 4 points (beginning, 2 in the middle near pixels 90 & 180, and the end). Fed with a single power injection cable fused at 15 Amp near the supply, cable length about 28 feet as I recall. Data and V- only from the controller, a RPi B+ and Pi-Hat via Beldon 2 conductor 20AWG shielded (I think). Shield is not used, just trimmed back and covered with shrink. Notes are in the graphic and to keep the insert size smaller resized to 1024x768 so the text suffered a bit. Fuses on the rabbit are 5 Amp. There may be an exception or two but from the connectors to pixels, wire lengths are no longer than about 20 to 25 inch. The tape (Yellow) on the PCV pipe hides most of the splices (fortunately).

The title of our introductory lighting manual contains a three digit number. What is that number? Clue: Display basics forum
