12-foot DIY LED matrix display is an office must-have [Video]

If you need to leave someone a message, you could either entrust it to a Post-It note or you could go the slightly more obvious route and use a 12-foot long LED matrix.

An ATMEL Mega8 controls the various LED arrays, and gets its commands from a Linux-based embedded computer. That also runs a basic webserver, meaning that messages can be set via a website or even your smartphone.
Altogether the project cost around €200 ($273) though half of that was the lengthy sheet of acrylic that covered the front of the matrix.

‘Wireless’ humans could backbone new mobile networks

People could form the backbone of powerful new mobile internet networks by carrying wearable sensors. The sensors could create new ultra high bandwidth mobile internet infrastructures and reduce the density of mobile phone base stations.Engineers from Queen’s Institute of Electronics, Communications and Information Technology are working on a new project based on the rapidly developing science of body-centric communications.Social benefits could include vast improvements in mobile gaming and remote healthcare, along with new precision monitoring of athletes and real-time tactical training in team sports, an institute release said.The researchers are investigating how small sensors carried by members of the public, in items such as next generation smartphones, could communicate with each other to create potentially vast body-to-body networks.The new sensors would interact to transmit data, providing ‘anytime, anywhere’ mobile network connectivity.Simon Cotton from the i...
