The only thing I purchased was a pair of cheep goggles to modify from dealextreme, everything else was removed from scrap electronics.
This is an easy soldering project suitable for beginners but could be done by twisting and taping wires. Please check out my videos, (part one links to part two) to see the project steps as I did them.
