Charge your smartphone using human power (and other stuff you missed)
A thesis project that may be the closest thing we've come to Tony Stark-level holograms? A 3D-printed implant for the skull? Yeah, we're definitely living in the future. As such, it can be easy to forget that the simplest things (such as electricity) are also the most vital, which is why we have inventions like this...
Instructables user The King of Random is indeed a little random. After all, what else would you call someone who could turn a cordless electric drill, some yarn, a salad fork, a mixing beater, a piece of lumber, some aluminum foil, and some tape into an electrical generator? (Well, aside from "awesome," anyway.)
Okay, this isn't so much important as it is just too cute for words. With the help of an Arduino Uno board and Clavia Nord Beat, a MIDI sequencer app for the iPad, the folk at Opificio Sonico have certainly turned Lego Bionicle's Toa Mata into something worthy of the price tags associated with the collector's editions of these little guys.
While there's plenty to be said about keeping good passwords and avoiding sites with questionable security certificates, some folks have apparently come up with a solution to password theft via screen captures and, er, over-the-shoulder scrutiny: Placing multiple cursors onscreen to confuse snoops. The current setup features five cursors and foils would-be password snoops half of the time, but its creators say that with 20 cursors, the system would prevent password-peeping 99 percent of the time.
