Voltage Regulator

Thought I would post some pictures of the voltage regulator. Although it sounds like the build tutorials will skip using the DC jack, I installed it regardless, as I will likely use this nice little kit for other projects in the future. For now, I'll solder a DC plug onto the end of my battery leads, making both more flexible down the road. One note: I could not find in the Solarbotics documentation for the kit what the correct polarity was for the jack. It ends up that the ring is grounded and the pin is powered. Make sure if you use the jack/plug combination that you get your polarity correct, otherwise you will likely damage your 7805 regulator, as I did once in the past on another project.
