Need a hand with your coffee? Builder Evan "treefort" Booth can help you with that. It turns out a coffeemaker is good for more than just making coffee—you can also use it to make a bionic hand.
In this fast motion video by Evan Booth, professionally known as Terminal Cornucopia, an engineer who "build[s] stuff out of other stuff," Booth turns a Keurig K350/300 2.0 Brewer into a prosthetic hand that is able to bend, move its fingers, and pick things up.
The five-minute video makes the building process seem short. But it took Booth 199 hours, 56 minutes, and 36 seconds to build the hand. He had no engineering plan in mind, "just a general idea of how things should be constructed." The only non-Keurig materials he used were adhesives and a 12v external power supply (a small adaptor). The tools he used were pretty common, too: a rotary, a heat gun, and common hand tools like screwdrivers.
Booth's Terminal Cornucopia began with a single question: "Can common items sold in airports after the security screening be used to build lethal weapons?" While it would be difficult and require some insane ingenuity, Booth determined that yes, it is possible to turn the trinkets and other objects sold or found in shops and restaurants into weapons.
"All these findings have been reported to the Department of Homeland Security (TSA) to help them better detect these types of threats," Booth wrote on his website.
Still, not all Booth's engineering acumen goes toward such morbid questions and equally terrifying answers. The Keurig-made bionic hand is one example, of many. In fourth grade, Booth used pens, erasers, and a Pop-Tarts wrapper to turn a pencil box into a model rocket launchpad. Looks like Booth was destined for second-hand engineering from the start.
