I have a quick concern. If you are running the entire rig off of a Mini-B usb port, they only provide 500mA. You might have to pigtail two USB Ports togeather to get 1A of current so you won't either burn out the host USB port or cause the computer to shut the port down completely due to overloading. Esepcially if your Touch Pro has the high-current charge hack running to let it draw 900mA off of the Bus. Either that or get a few Lithium AA cells to add auxillary power to the chamber. Just my $.02
