Aren’t ball races and marble runs fun? Wouldn’t they be so much more enjoyable if you didn’t have to climb back up the ladder each time, as it were, and reset the thing? [Johannes] wrote in to tell us about a wee robot with the Sisyphean task of setting a ball bearing on a simple but […]

The nanoSplatch™ nSP250 is a surface-mount antenna for embedded WiFi/WLAN and other 2.4 GHz or 5.8 GHz ISM or U-NII frequency band applications. It uses a grounded-line technique to achieve outstanding performance in a tiny surface-mount package. The nSP250 exhibits low proximity effect with a very hemispherical radiation pattern, making it ideal for handheld devices

New modulation method increases operational lifetime of switching power units through digital, highly dynamic control and the use of film capacitors. Switching power units are used for the power supply of many electrical devices, e.g. computers, LED lights or laser welding equipment. They convert alternating current from the mains into the direct current required by

WebUSB connects remote devices directly to the browser via the web A awesome feature in Chrome is support for the WebUSB API, which allows web apps to communicate with USB devices, once user consent is given. This opens up a ton of cool possibilities for the future of web application and hardware interoperability, but may

Nui is an IR controlled volume controller for analog audio. It sits between your audio source and speakers and can amplify or reduce the volume using IR commands (and eventually BLE). Why do I need this? It all started because I have my trusty Logitech Z-2300 speakers and subwoofer I purchased back around 2004/5. They

This is my school project for the 5th year of high school (I’m Italian, we have 5 years of high school). It consists in an artificial hand controlled by a glove with flex sensors. The artificial hand reproduces the movements of the hand with the control glove, wirelessly. The hand and the glove works both
