This project came about because I have a decent amount of LED projects around my house and my friend asked me if I could turn one of those into a light he could put behind his TV! But he has his TV hung on the wall and didn't want to have any wires hanging down or anything that required being plugged in. I took a look at his TV, and it, along with most new flat panels, have a couple USB sockets on the side. And I thought PERFECT I can just use the 5 volt power out of the USB port!
This is a really simple project that looks great! You can use the idea of this project for many different ideas and areas-- not just for behind the TV!
Step 1: Parts and Tools needed
USB cable (cannibalize it off of any old or broken electronics)
Container (any container that you like, choose one that fits your project!)
Resistors (correct resistance for a 5-volt power supply and your LED's. If you are not sure check out the LED calculator)
LED's (any color you desire)
Spray Paint (whatever color or texture you want!)
Hot Glue Gun
