DIY $5 Golf-Swing Trainer

Who needs to spend hundreds of dollars on fancy "As Seen on TV" golf trainers when you can make one yourself, easily. Old man winter may be keeping you off the links, but that isn't an excuse to not work on the golf swing. This training aid uses LEDs attached above the head of the golf club to analyze and perfect the swing. It costs a mere $5 to construct and could provide hours, upon hours of entertainment. It may not turn you into the next Tiger Woods, but at least it may eliminate the nasty slice or hook. Jump to see a video explanation of the device.
