Flutterby™! :

When I was a kid I had a book that must have filtered down from my Dad's childhood, called "The Boy Mechanic". It came from a different era, when people built stuff, and had articles on everything from manufacturing your own O gauge model railroad track to building go-carts from scratch and on.

Sometimes I lose faith in humanity, I think that in this age of ridiculous software and "business system" patents (I was gonna provide a list, but it got too long) and grandiose government boondoggles we've lost that individual tinkering with real hardware that's given us so much neat stuff. The Roton is one such, The Carter Copter is another. There's also an unofficial Carter Copter fan site .
