Over at Hackaday, a quadcopter made from ewaste.
"It’s pretty obvious that the main rotors are PC Fans, 140mm in this case. Normally, these wouldn’t be able to create enough lift to get out of their own way except the on-board 24v Dewalt cordless tool battery bumps up the fan speed to 15,000 rpm."

I really enjoyed this whole thread... thanks guys, I needed that!
Tier 1 of the maker movement, where the guy only makes a proof of concept that never flies. These guys usually become middle managers & make $50 billion on kickstarter donations.
Euan, I really want to make a quad frame using sticks taken from trees. Just lash them to together with twin. I guarantee you I could make it fly. I've been wanting to do it just to show how easy and simple it is to build a quad frame.
Fake or not...dammit, someone has to do this.
Fake or not i know where to look for some prop guards now :D
