Have trouble waking up on time? Meet the Wake-Up Machine. This contraption slaps the sleep away with a large rotating rubber hand.
Vlogger and self-described robotics tinkerer Simone Giertz invented the device because she says waking up in the morning sucks. "I was thinking, why not make an alarm clock that makes your bed a little bit less comfortable ... because it slaps you in the face?" she explains in a vlog.
12 Eye-Opening Alarm Clocks
Giertz, who lives on a houseboat, says she got a rubber hand Halloween prop and thought it would be fun to use with an alarm. Fortunately she cleaned the fake blood off first, since this whole idea is terrifying enough.
She took an old alarm clock and then wired it to an Arduino UNO microcontroller for the relay. The tripping alarm starts a strong motor. A few burnt transistors later and boom: The Wake-Up Machine was born. The first duct-taped version rotates in a way that catches her hair, prompting Giertz to rip the device's front part off the wall for a painful detangling.
