BoardX: Arduino on steroids

By - November 25, 2011 7 Pictures
Something of a prospective big stepbrother to Arduino, BoardX is a new DIY electronics kit dreamt up by robotics enthusiast turned entrepreneur, Kevin Green. Like Arduino, BoardX is a customizable and expandable motherboard that forms a base, schematically and structurally, to whatever electronics wizardry the end user has in mind. What separates BoardX from Arduino is its larger physical size, greater current-carrying capacity, and the fact that the board does not come with an integrated processor. Users must select their own.

Minimalistic Bluetooth speaker is activated by twisting the cap

By - November 25, 2011 8 Pictures
Bluetooth speakers are not particularly complex devices in terms of operation - you just pair them with a Bluetooth-enabled device, adjust the volume and enjoy the sound. However, a duo of industrial designers have created the Hidden Radio And Bluetooth Speaker in an attempt to make it even simpler and more intuitive. The unit is also claimed to offer an impressive 30 hours of battery life. Read More

AAXA P4 Pico Projector comes with 75 minutes of battery life, Windows CE onboard

By - November 24, 2011 7 Pictures
Handheld projectors can be very useful devices when you need to project a large image on-the-go, but many of them lack enough brightness, resolution and battery life. California-based company AAXA Technologies has rolled out its P4 Pico Projector with the aim of addressing some of these issues - it offers 80 lumens of brightness, 75 minutes of battery life and can handle 720p videos.

New tech allows lithium batteries to charge faster, and hold charge longer

By - November 20, 2011
For those of us using smart phones, an all-too-familiar problem is that of a dead battery. The computing power, as well as the multi-purpose abilities of modern-day phones is nothing short of amazing. However, until battery life catches up with the functionality, we're still forced to carry multiple devices. For example, what good is 32GB of memory to store music and movies if it leaves me with a dead phone after an hour or two of my favorite tunes? Even though my phone can easily handle the music and movie abilities of my iPod, I still carry the iPod. I still have a GPS in my car, even though my phone is more than capable. New technology from Northwestern University is aiming to change all that. Engineers there have created an electrode for lithium-ion batteries - the rechargeables commonly found in our devices - that allows them to run ten times longer, while only taking only one-tenth of the time to charge.

Hobbyist builds wrist-mounted, laser-sighted crossbow

By - November 4, 2011 3 Pictures
A lot of people think crossbows are pretty cool. Lasers, miniaturized things, and wearable devices also tend to rate pretty high on the neat-o-meter. It goes to follow, therefore, that a small wrist-mounted laser-sighted crossbow should have a lot of admirers. Well, laser hobbyist Patrick Priebe built just such a device, and his video of it in action has already racked up over 100,000 hits in just four days. As it turns out, the "WristBow" is just the latest of his cyberpunk-esque creations. Read More

New paper-based explosives sensor is made with an ink jet printer

By - October 30, 2011 5 Pictures
Detecting explosives is a vital task both on the battlefield and off, but it requires equipment that, if sensitive enough to detect explosives traces in small quantities, is often expensive, delicate and difficult to construct. Researchers at the Georgia Tech Research Institute have developed a method of manufacturing highly sensitive explosives detectors incorporating RF components using Ink-jet printers. This holds the promise of producing large numbers of detectors at lower cost using local resources. Read More

Bodymetrics pods scan customers' bodies to get their clothing measurements

By - October 25, 2011 4 Pictures
London-based Bodymetrics and 3D machine vision company PrimeSense have developed a full 3D body scanner that is designed to make finding the perfect pair of jeans a whole lot easier. Its "Body Mapping" platform uses eight PrimeSense 3D sensors to take all of a client's necessary measurements and map their body shape. This data is then accessed by retailers, to find the clothes which best fit that client. Initially the scanner is going to be used by Bodymetrics "Fit Stylists" to suggest the best-fitting jeans for female customers. The next step is to revolutionize the online clothing retail market.

ITRI develops re-writable, bendy, and electricity-free e-paper

By - October 25, 2011 2 Pictures
Taiwan's Industrial Technology Research Institute (ITRI) has developed a highly flexible electronic paper that's both re-writable and re-usable, and like the Boogie Board electronic memo pads, the technology doesn't need electricity to retain the screen image. The institute is currently in licensing talks with manufacturers at home and in the U.S., and has taken first prize in the Materials and Basic Science and Technology category of the Wall Street Journal's Technology Innovation Awards.
