Good day to all the awesome DGC’ers and a very special thanks to the Dude, Scotty and Guru for keeping it real.

I have been building LED systems for a few years with my main objective being low cost and efficiency. Finding part and suppliers is very hard where I live and shipping is a bad word. Its about a 12-14 hour drive to the closest big city, very nice drive. So I must keep the cost down. Sometimes finding one mans trash and turning it into another mans grow treasure. Old computers are a good example. They have heat-sinks, wires, power cords and the case can be used for the housing. Stores that are closing up shop may have some aluminum casing and shelving that can be used for building frames. When it comes to LEDs and drivers, it gets a little harder to lower cost.
