Ever want to see what is inside a huge High Voltage Transformer? The Geek Group got one donated and took it apart for everyone to have a peek. The transformer is an old medical XRAY transformer, there is a huge safety disconnect contactor under the top cover and the entire case is filled with mineral oil for high voltage isolation. They spread it out over 3 videos and some

Stamps.com seems to be promoting their service in all corners of the web these days. Their scales are a big part of how their service works to allow you to print your own stamps at home. Only thing is the fully functional scale they provide is only good if it is connected to a computer since there is no display on it (looks like the new scales do have
   Rohit Gupta needed a way to speed up PCB etching. Heating the etchant and agitating it are both well known ways of speeding up the process. If you are on a DIY budget this normally means you will be stuck sloshing the etchant back and forth for 10 minutes or so. Rohit developed the Open Agitator which uses a CD-ROM Drive Drawer to shake a tray back and forth. A
Remember the Espruino we featured back in January? Check out their Espruino Kickstarter. The Kickstarter is fully funded so these will be produced and if you act fast you will be able to snag one for £19 through kickstarter. I am thinking that we will start to see a new group of web programmers that make the plunge to microcontroller programming with this device. This device is tiny and packs
If you are looking for some DIY home automation and want to play around with Pi and Arduino have a look at heimcontrol.js. James Bruce used it for a simple setup and you can see his results in the video below. “heimcontrol.js was created to gain experience in Node.js, MongoDB, Websockets and a lot of other great technologies that were used in the project. Take a look in the package.json for
 If you need to squeeze a bit more speed out of your Arduino project Overclocking with liquid Nitrogen might not be the best way but it sure looks like fun! Via: Dangerous Prototypes. “Why CMOS microchips could work faster when cooled? CMOS speed is usually limited by how fast transistors could recharge parasitic capacitances (gate capacitance and interconnect capacitance) via parasitic resistance/inductance of the wires. When cooled wire
