Tip: Cheap Power Supply
 

A while back I was trying to get my panel wired and needed a power source. I ended up using a car battery charger without realizing that this thing puts out rectified AC. This caused a gigantic hum in my radio and I thought I'd barbequed the whole thing until somebody on here put me straight. I went back to the local electronics store in search of a power supply or battery. A guy next to me in line suggested I just get some lamp cord and a car cig lighter plug. Well 5 bucks and a half hour later I had all the power I needed straight from my Toyota truck. So simple and soooo cheap.
