GT35pro 35mm DOF adapter power unit.

I've added the GT35pro power unit picture here. The power unit takes one AA size battery and has a jumpstart button. It uses a standard 3.5mm mono/stereo jack on both ends to supply power to the adapter. So if your cable craps out, you can easily get a replacement at any store that sells audio accessories. I will incorporate a power on indicator in the near future.For the motor to vibrate properly, it cannot vibrate too fast. Sometimes when the power is turned on the motor will not start spinning as it is set to rotate at a slower speed. Press the jumpstart button and it will start the spin. The small hole you see near the jumpstart button is the adjustment for the vibrating motor speed. You need a small flat head jewel screwdriver to adjust it. It has been preset by me and there should be no reason to adjust it, unless you know what you are doing.
