Yes, I'm aware of the strips and have played with the ones from sparkfun. Those are really cool but I want to individually wire and control tiny led's onto a device. Picture a christmas tree that you could do effects on using the lights. Actually what I want to do is embed them into the plaster on a wall during a renovation to make it twinkle and change colors.
- HeyLaughingBoy 14y agoIt's not at all difficult to build. However, if you really want the LEDs controlled individually, the problem will be the large number of connectors and wiring. If we assume that, as in your other post, you want to connect 100 RGB LEDs, then you need 100 four-terminal connectors. Assuming you are using 0.1" spacing (I find smaller spacing connectors to be unreliable), each connector will require at least 0.5"x0.75" of PCB space (you need to leave room to be able to plug/unplug the connector). Next each LED will also require a mating connector and 4x whatever length of wire you need and a mounting method. The first time I had a client who asked me to make up wire harnesses of 60+ wires, 4 feet long, it was a huge surprise just how labor intensive it was to build a dozen of them. And copper is heavy
- nathanstitt 14y agoYes, I'm not looking forward to the wiring/soldering job that's for sure. An affordable switching driver is what I was missing, but have just found one.
