Sometimes turning a screwdriver is just too strenuous an activity for its own good, and while electric-powered versions have helped alleviate the problem for quite some time, none have used a gyroscope to get the job done. Black & Decker has teamed up with InvenSense — which provided gyroscopes for Nintendo's Wii MotionPlus accessory — to release the Gyro 4V Max, what the companies claim is the "world's first motion-activated screwdriver." Now, DIYers only have to turn their wrist once in either direction to get the screwdriver moving at variable speeds with the help of a Z-axis MEMS gyrosope. Best of all, the Gyro's Lithium rechargeable battery can hold a charge for up to 18 months, leaving you with one less thing to worry about. The Gyro 4V Max can be picked up this October for $39.97 from Lowes, Walmart, Amazon, and BlackandDecker.com.
