This is the final version of the Touchpad Self Powder USB hack. This was achieved by wiring a 5V DC to DC Step Up from Sparkfun.com directly to the battery and then attaching it to a USB extension cable. The extension cable is then attached to a USB OTG cable and the device of your choosing.
Note this Step Up's current is rated at a typical output of 300mA, not the standard 500mA USB output, so some devices with a higher pull may not work. The majority of flash drives, keyboards and mice should work without issue.
The Y cable was made from a Micro USB cable and a standard extension cable.

The 5V DC to DC Step Up can be purchased here: http://www.sparkfun.com/products/8290
