During my summer vacation I've been working on electronic projects. I've made power regulators, I've made light shows, I've even used a dip switch. My favorite thing I've made, though, is a POV (Persistence of Vision). 
A POV is basically a bunch of LEDs that when you wave your hand while holding it it makes either words or drawings. The lights pulse so that when it's moving really fast it makes a display. Persistence of Vision is sometimes used in clocks, but we are going to put ours on our ceiling fan [editor's note: so that when the fan whirls around, you can read "Sam and Ben's Room" all night every night].
