After the binder clip stand, here’s another way to prop up your iPhone that you can make from everyday office supplies, courtesy the enterprising folks at Geeky Gadgets who were looking for an impromptu stand to better watch the presidential inauguration.
You’ll need four or five pencils, probably five to support an iPhone 3g.
Take two pencils with one rubber band at either end to make the horizontal phone support. Then make a triangle using two more pencils. Add the final pencil as the back support. You can adjust stability and support given by tightening the top rubber band.
One caveat: If you have a slippery desk, try making the stand with pencils that have erasers, putting the eraser end on the desk for added support.
