Sonic Screwdriver

For the upcoming Nashville Mini Maker Faire, NashMicro is hosting a booth where they will be allowing participants to build “sonic screwdrivers”.  The screwdrivers will be part of a joint exhibit between NashMicro and the LeanKit TARDIS.  If you can’t be at the Faire, here’s how you can build your own sonic screwdriver at home using just a few cheap parts.
