A funny name for a funny gadget. We all know usual solar powered calculators, not a big deal if you calculate in light room but what should you do when you are doing that at night or in a dark room? Easy, just take a different calculator; Shake-u-lator will charge as you shake it.This calculator uses the Principle of Electromagnetic Energy to power itself. You just need to shake it side to side if its battery runs off the juice and it will come back from the dead. Faraday’s Principle is based on a magnet and a copper coil. When the magnet goes through the coil it generates a small amount of energy. Several shakes and its battery is fully charged.
Its LCD display does not take much energy just like its processor to make calculations so you will not have to shake it up that often.
You can find one and buy it online if you are interested, it will cost you about $ 19. Good luck.
