Carbon nanotube pencil leads used for drawing sensors onto paper: " We’ve already seen a pen with silver-based ink, that lets its user draw electrical circuits on ordinary paper. Now, scientists from MIT have brought similar ‘hands on’ technology to the humble pencil – they’ve compressed carbon nanotubes together to form a pencil lead substitute, that has been...

Labstrip project wants to turn the iPhone into a mobile science lab: Mobile computing is changing the world. Tasks that could recently only be performed at a desk can now be done anywhere. It may be some time before an entire laboratory can be replaced by an iPhone, but the men behind a new Kickstarter project are taking an ambitious step in that direction...

I love this cool prototyping board Adafruit sells. Bex breaks it down: We now have a way to attach a Raspberry Pi computer to a plastic ‘dish’ with a full-sized breadboard. We designed it carefully to make it as easy as possible to attach and detach the Pi. Since the Pi computer does not have any mounting holes, we use these nifty plastic edge ‘grabbers’ – they are incredibly...

Tinker-friendly developer gadget Raspberry Pi has received a jolt of Android, with a functional – though incomplete – port of Ice Cream Sandwich for the super-cheap computer. A work in progress for some time, according to the Raspberry Pi team, but kept quiet because the build isn’t quite what you’d find publicly available, the Android 4.0 port could well turn the $35 PC into your...

The Arduino Wifi Shield is finally here! We’ve been working for a while on this new wifi shield for Arduino that is quite different from what you can find already on the market. Instead of just getting the usual pre-made module we decided to build a product that would encourage hacking and modifications so we decided to use an AVR32 processor running an open source version of TCP/IP and the...

The developers of the Raspberry Pi $35 mini PC has introduced a new kit which can help transform your Raspberry Pi into an Arduino style hardware controller, allowing you to drive motors or power robotics. The Gertboard kit comes with both an assembly manual and a user manual, together with plenty of programs to demonstrate how to get the most from your Gertboard and Raspberry Pi. Watch the...

The open-source Arduino micro-controller is a very useful piece of kit which has been implemented by hackers to power countless endeavors from Musical Umbrellas to Angry Birds Slingshot Controllers. For some projects however, the flexibility of the Arduino can be overkill and it's this issue which prompted Digispark to create a simpler, cheaper alternative - a tiny Arduino-compatible...

If you already have your hands on a Raspberry Pi and are eager to make some LEDs blink and read the status of pushbutton switches, I want to share with you this excellent tutorial by Tedb0t. He shows you the ins and outs (so to speak) of how to use the general purpose input/output (GPIO) pins on a Raspberry Pi board. He covers everything from physically connecting to the GPIO headers to...
