The paper is the circuit: Scientists create graphite-based paper circuitry

Given the low costs and extensive applications that could be possible with flexible paper circuit boards, we've seen many ideas for their production, from printing with silver ink to embedding chips within paper. Now, however, scientists have developed an elegant method for selectively changing the very nature of the paper itself into conductive graphite. Unlike polymer-based flexible circuits, these paper circuits are, ironically, able to withstand the high temperatures generally used in the production of electronics. Read More

Hand-held "sound camera" shows you the source of noises

If you work with machinery, engines or appliances of any type, then you’ve likely experienced the frustration of hearing a troublesome noise coming from somewhere, but not being able to pinpoint where. If only you could just grab a camera, and take a picture that showed you the noise’s location. Well, soon you should be able to do so, as that’s just what the SeeSV-S205 sound camera does. Read More

Making solar cells with a kitchen microwave

For most people, experiments involving a home microwave typically don't go much further than inflating a marshmallow like a balloon or reheating leftovers in plasticware – both with messy results. For metallurgists though, microwaves are sometimes employed to efficiently process metals, which is how researchers at the University of Utah found themselves using a secondhand kitchen appliance in their lab. Their resourcefulness paid off recently, when the team discovered a method for creating solar cell material with just a few basic ingredients and an old microwave.Read More

PayTouch lets you pay for purchases using your fingerprints

If you went into a store without any cash, cards or mobile devices, would you be able to buy anything? Well, if both you and the store were using the new PayTouch service, the answer would be yes – all that you’d need to do is place two of your fingers on the fingerprint scanners of the PayTouch terminal.

Honda teams up with Sekisui House on smart home robots

With one in five Japanese citizens now aged 65 or older, various robotics technologies are being developed to prolong independent living and improve quality of life at home. The main alternative to nursing homes and hospitals would be smart homes designed around the needs of the elderly. Earlier this week, Honda announced that it will test some of its life support robots in a mock household environment at the Future Life Showroom, in Sekisui House's brand new SUMUFUMU Lab.Read More

Daily Brick's Lego iPad Dock Kit: Review + assembly guide

When Lego kit specialist The Daily Brick made contact to see if we'd like to review its Lego iPad Dock Kit for Retina or iPad mini, bits were champed. This was partially because I don't actually have a Lightning dock for my Retina iPad, and partially because… you know… Lego. But as fun as Lego is, most of the joy is in the building. Is a Lego iPad dock really up to the rigors of daily use? Gizmag built one to find out.Read More

Klauf Light Bar: LED lighting made cheap, easy and extendable

The latest LED lighting product to hit Kickstarter, Klauf Light Bars are semi-portable, low-cost LED strips which can be connected end-to-end more or less straight out of the box. They come in 6-inch and 12-inch (15 and 30 cm) lengths, which can be arranged as you like up to a length of 15 feet (or about 4.5 meters). They can either be slotted together directly or connected with cables, which is handy if you intend to install them under kitchen cabinets which extend around a corner (recommended), or make giant illuminating nunchaku (less so).Read More

The Siva Cycle Atom charges phones through the power of pedals

Over the past several years, we’ve seen a number of bike-mounted products designed to charge the user’s phone using pedal power. Some of these have included the PedalPower+, the EcoXPower, Nokia’s Bicycle Charger Kit, and BioLogic ReeCharge Power Pack. One of the latest such devices, the Siva Cycle Atom, is hitting Kickstarter – and it's quite a bit more compact than most of the competition.Read More
