The cell phone holder can be found in many cellphone shops or at eBay.
Disassemble the cell phone holder into three pieces-gripping cradle, goose-neck, and suction cup. We don't need the suction cup.
Wrap the grip tape around the goose-neck, and attach the goose-neck with bicycle flash light mount.
Mount the goose-neck on the umbrella tube. Bend the goose-neck to adjust the angle of the pedestal head.
Put the pico projector inside the gripping cradle, and connect the pico projector with iPod Touch.
