What we’re seeing is Lichtenberg Figures form from an electron beam getting zapped into an acrylic prism. The electric trail of the lightning strike is so badass. It’s like trapping a lightning bolt in a glass box forever, a force of nature on display.
Here’s a fun video showing the rainbow of colors that anodized titanium can become. There are blues and purples and gold and it all changes so fast. It’s basically magic (or science!) that just applying voltage to a piece of titanium in an electrolytic bath can transform the color completely.
Looks like you screwed with the wrong old man today, punk. I may look grey and infirm, but I'm packing a million volts of incapacitating, jaw-clenching self-defense. Or offense! This grandpa's crazy! The Zap Cane also has a flashlight. Beware!
In this week's Gizmodo University: Discover Electronics, we're diving headfirst into the principle theories of electronics. The second of four classes in this series, "Volts, Amps, and Ohms" is presented in conjunction with Sparkle Labs.
The technology behind the MotoCzysz E1pc isn't just the future for motorcycles, it's the future of electric vehicles. When you have 10x the battery power of a Prius and 2.5x the torque of a Ducati it's easy to see why.
[Cue Fairytale music...]Once upon a time, a geek found that he had way too many gadgets, and too few AC outlets to use them all at once. A simple powerstrip would have been a easy fix, but because he considered himself a serious gearhead, he wanted *special* powerstrip.
Researchers at Rensselaer Polytechnic Institute and MIT have developed a battery that uses carbon nanotubes and paper to make a flexible battery that can be cut by scissor and could eventually be printed. The energy density is fair, at about 110mAh/gram, and small prototypes are powerful enough to power small fans.…
