Whoosh Boom Splat: The Garage Warrior's Guide to Building Projectile Shooters
William Gurstelleis the author ofAdventures from the Technology Underground,Backyard Ballistics,Building Bots, andThe Art of the Catapult. The number of hours he’s spent crafting fighting robots and catapults instead of working at, say, his normal job (as an engineer) is, in Bill’s own words “scary to contemplate, but it serves a purpose.” When not building devices that make stuff go whoosh, boom, and splat, Bill is a contributing editor atMakemagazine and writes frequently forWired,The Rake, and several other national magazines. He lives in Minneapolis.
