[QUOTE="i13, post: 84766, member: 21708"] He's incorrect at 2:47. It does not matter which direction the electricity flows through the strip; you can power it at either end and it will work. The data and clock signals only work in one direction though. The power injection every 50 pixels only applies to nodes. Strips seem to go further. Assuming he means negative when he says ground, he hasn't injected the positive. He'd get even better results if he did. The way he did it also created a ground loop (circular negative wire through the pixels). You can usually get away with this but it can occasionally cause flicker. [/QUOTE]

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