Yay! It's not the best one out there (Simon's is awesome) but the components are EASY to find and it took under two hours from start to finish.

Next step: Add a switch and a power LED. The LED will probably just be patched right against the regulator and the yellow power lead was left so long to allow for the switch.

Enjoy.
