Hairdryers and Blowers

The race track for maker central was built to race wind powered strandbeest against wifi controlled strandbeest, the trouble with the wind powered version is finding the wind indoors. This means letting people blow spittle all over everything, providing some kind of wafting device which usually ends up as a whacking device or an electric fan. I bought a few cheap hair dryers but they barely shifted any volume and couldn't make the blades spin. I've used these squirrel cage blowers before for other projects and know they can really shift some air.

The fan runs off a simple 12V power supply which is passed through a microswitch in the handle. The lever for the switch bent into a button shape to form a trigger, that way the fan is only on when it is required and pointing in the right direction.
