What kind of potentiometer did you use? Ohms?

There are three sets of LEDs. Each LED in each set is wired in Parallel, that is (+) to (+) and (-) to (-). Then each of the sets are wired to the next set (+) to (-) in series. The two remaining leads from the end two sets are wired to the battery. Thus, each set is only connected to one third of the 9V battery, or 3Volts.

Did you put any resistors in to prevent the LEDs from being burned out by the 9V? If so, what value, how many, and where?

Thanks for the write up, looks awesome!

Any shots with this in the dark or sample images to see how much light this thing throws off?

Test shots. Works great in light, a bit too bright at night time though if your eyes are adjusted to the dark. Haven't messed around too much with the dimmer at night time but its a must.
