The little PCB's turn up today so i can really get going on getting my RGB dumb icicles done. Each drop will be a constant 7 RGB leds so that i can use my normal 28v DC i use for all dumb strings. The little pcb was designed to put the dropping resistors on and provide a simple t-junction from the horizontal power run. Like this The front has the resistors and drop wiring. The back has the horizontal main cabling I will be using the C9 covers like this Next step is to design the 3D printer channel to hold each pcb, we are working on 100mm spacing as i have 20M of gutter and a little over 200 of the RGB sections already soldered up.
