M'kay... I didn't figure I'd get any help on this particular subject. I went ahead and tossed together something.
I took out the six AA batteries in the battery pack. I found a 9v 200mA power transformer (closest I could find to 7.2v) and took it apart. I couldn't find the exact current rating of the motor but after some searching I found out that the charger puts out 200mA. I put in some round copper pieces where the batteries used to stick out of the battery pack. A few resistors later. Voila
I just wish Dremel made something like what I tossed together.
