Fan fare

How easy it is to delight a gadget freak. Just stick a ditsy little LED tschotske in front of him (or in this case her) and she’s grinning like a monkey. (Do monkeys grin? Must check)
This is a tradeshow giveaway, a personal fan, battery-operated, with two flexible plastic blades and a single foil strip with 5 red LEDs running down the center of one of ‘em. Turn it on, and after awhile (if you baby the blade into the right position), it displays the words “100% SATELLITE TRACKING,” one right after the other.
OK. I know theoretically what’s going on here, but my brain’s not really comprehending how 5 little LEDs are making it do this. Seems like those LEDs would have to be flashing pretty fast…
–happy sigh–

Some LEDs have a switching frequency in the megahertz range.

Shows how long it’s been since I used the soldering iron for something besides sculpting wax, eh?
I always knew your were a Heathkit kind of gal.
