Wii nunchuck controlled servo bot

[Stuart.Mcfarlan] is back. This time he has added Wii Nunchuck control to his servo bot. You may recall servo bot, or SERB, from a few weeks ago. Now the little bot can be controlled by either the joystick, or the gyroscope in the Nunchuck. Too bad its wired though, wireless is the next step right?

Measuring current through USB

[gmgfarrand] wanted to be able to measure the current being pulled through his USB.  He realized that even though he could just cut open the wire and measure at any point, a permanent tool for this would be quite useful.  This is a simple modification that shouldn’t take long. All you need is a spare USB cable and an enclosure. He ultimately filled his enclosure with glue to keep everything in there and solid. lets hope his soldering holds well.

900,000 volts at your fingertips

[Nickademuss] has put together these great instructions on how to build a 900,000 volt Van De Graaff generator. For those unfamiliar, Van De Graaff generators produce massive amounts of static electricity. They are usually the things you see in science centers that make people’s hair stand on end. [Nickademuss] put a lot of effort into this, he created 3D models and diagrams for many of the steps and gave a very detailed step by step breakdown.
