You cannot undertake any DIY project without the right tools, and one of the most vital is the venerable screwdriver. There are plenty of fancy driver sets out there, but you've still got to twist your wrist to do the work. The Wowstick is even fancier because it does the twisting for you. This is a super-compact electric screwdriver currently cleaning up on Kickstarter that looks like a pen and comes with up to 56 different bits.
The Wowstick has an aluminum unibody design with two buttons around where your thumb would rest on a pen. These buttons rotate the bit clockwise and counter-clockwise. The body is 16mm in diameter and weighs about 50 grams. There's also a cap that covers the bit attachment when not in use. At the opposite end, you have a microUSB port for charging. Points for not using a DC barrel or proprietary connector, but a more modern Type-C plug would have been better.
