Splinter Bike - a bicycle built ENTIRELY out of wood

By Paul Ridden

Just over six months after making a joke bet in his front garden, Michael Thompson has lived up to his idle boast of being able to make anything out of wood. Unlike other bike designs where wood is just one of several materials used in the construction – like the duo from Audi and Renovo, which has a hardwood frame – every part of the Splinter Bike is made from either birch plywood, Lignum Vitae, Ekki or an old broom handle. Thompson's friend and accomplished triathlete, James Tully, now has the unenviable and certainly uncomfortable task of riding the 31 kg (68 pound) engineering marvel into the record books.

Thin-film flexible 'Paperphone' created

By Ben Coxworth

Researchers from the Human Media Lab at Canada's Queen's University have created a fully-functioning floppy E-Ink smartphone, which they also refer to as a paper computer. Like its thicker, rigid-bodied counterparts, the Paperphone can do things like making and receiving calls, storing e-books, and playing music. Unlike them, however, it conforms to the shape of its user's pocket or purse, and can even be operated through bending actions.

"This computer looks, feels and operates like a small sheet of interactive paper," said its creator, Roel Vertegaal, who is also the director of the Human Media Lab. "You interact with it by bending it into a cell phone, flipping the corner to turn pages, or writing on it with a pen."

TV in a Card brings video to brochures and greetings cards


By Paul Ridden

It is said that a picture is worth a thousand words, and a moving picture worth even more. Now a company in the UK is enticing businesses to go beyond the confines of eye-catching text, colorful graphics and product photos with TV in a Card.

The brainchild of Russell Lawley-Gibbs and Robert Green, a standard TV in a Card folder has A4 (297 x 210 mm / 11.7 x 8.3 inches) dimensions and opening the cover reveals a 4.3-inch, 320 x 240 resolution, 16:9 aspect LCD display powered by a custom board with built-in storage for about 30 minutes of video footage. There's an included speaker and headphone jack, and the Li-ion battery lasts about 1.5 hours before needing to be charged via the included USB port.

New type of rechargeable battery – just add water 

By Alan Brandon

Scientists at Stanford have developed a battery that uses nanotechnology to create electricity from the difference in salt content between fresh water and sea water. The researchers hope to use the technology to create power plants where fresh-water rivers flow into the ocean. The new "mixing entropy" battery alternately immerses its electrodes in river water and sea water to produce the electrical power.

Herding Swarms of Microrobots

Tiny robots self-assemble with a single command.

By Kristina Grifantin

Imagine a swarm of microrobots—tiny devices a few hair widths across—swimming through your blood vessels and repairing damage, or zipping around in computer chips as a security lock, or quickly knitting together heart tissue. Researchers at the University of California, Berkeley, Dartmouth College, and Duke University have shown how to use a single electrical signal to command a group of microrobots to self-assemble into larger structures. The researchers hope to use this method to build biological tissues. But for microrobots to do anything like that, researchers must first figure out a good way to control them.

"When things are very small, they tend to stick together," says Jason Gorman, a robotics researcher in the Intelligent Systems Division at NIST who co-organizes an annual microrobotics competition that draws groups from around the world. "A lot of the locomotion methods that have been developed are focused on overcoming or leveraging this adhesion."
