It’s been 150 years since Scottish Physicist James Clerk Maxwell showed off the world’s first color photograph at a Royal Institution lecture in London. His discovery is incredible but, technically, it shouldn’t have worked. More
Watermelons are delicious, especially during the summer. I search far and wide for the biggest, juiciest, perfectest watermelon around. But sometimes they can get too big, like this field of watermelons that’ve exploded like landmines. More
This, dear reader, is the iDVM Digital Multimeter — the world’s very first iDevice-enabled voltmeter, from Redfish Instruments. Designed with auto technicians, electricians and engineers in mind, the iDVM uses an ad hoc wireless network to connect to any iPad, iPhone or iPod Touch, allowing users to record voltage, resistance and current directly from their palms. Once you’ve purchased the multimeter and downloaded the accompanying iDVM app, you’ll be able to gather electrical measurements from up to 30 yards away from your target, log data over extended periods of time and export your findings in spreadsheet or graph displays. The rechargeable battery-powered device can also read your measurements back to you, which should make you feel slightly less lonely while digging around your car’s engine at 3 am. We’re still not sure why anyone would want to juggle their iPhone while chasing down a shorted wire, but if you do, the iDVM starts shipping on June 1st, for $220 — which could buy you about 40 less complicated multimeters from Harbor Freight. Full PR after the break.

Call me a hypocrite, but while I’m disdainful of Design for the Sake of Design, I’m all for Mechanical Engineering for the Sake of Mechanical Engineering. Dave Johnson’s self-built Magnet Machine sends Buckyballs on a little journey with no purpose, but does demonstrate some cool bits of electromagnetic science:
This machine manipulates small spherical rare earth magnets, slicing one at a time from the end of a long chain, moving it around a bit, then dropping it back to re-connect at the tail end of the chain.
It also demonstrates a little snippet of science called eddy currents. Watch how slowly the magnet falls through the aluminum tube compared to falling through air: the falling magnet generates an electrical current in the tube, and that current in turn generates a magnetic field that opposes the movement of the magnet, slowing it down dramatically.
There seems to be no lack of options for cloud music players on Android these days, but what about your neglected iPhone? If you have a Dropbox account and use it to store music and podcasts, BoxyTunes makes it easy to grab those audio files on the go. More
Back in March, we saw a project using a head-mounted Kinect to sense and alert the user to obstacles in their path. Researchers at Luleå University of Technology in Sweden are working on a similar system, but building it into a wheelchair.
It was tested this week by a grad student hopeful who is himself visually impaired, and he pronounced it solid. The system looks quite bulky, however, and is limited to detecting objects within a narrow plane, so it wouldn’t pick up, say, a curb or overhang.
Still, it’s interesting research, and could be the start of a new kind of intelligent wheelchair that could let blind and partially sighted people get around their homes a bit easier.

In your daily Netflix news, the latest report on Global Internet Phenomena for spring 2011 from Sandvine has called out the movie service as the largest single consumer of bandwidth on the internet in North America. The last report in October suggested it made up around twenty percent of internet traffic during prime time, but this time around the stats say it accounts for 30% of traffic during prime time, and 22.2% of daily internet traffic. Sandvine gets the data from ISPs using its broadband technology and now foresees “Real-Time Entertainment” (which includes Netflix) shooting up over 55% of peak internet traffic by the end of this year. It also reports on net traffic from other regions, noting social networking outpaces YouTube traffic in Latin America, while European subscribers use twice as much data as North Americans. We’ll have to wait and see if these stats are waved in our faces to justify the next round of bandwidth caps or throttling, in the meantime you can click through for more stats or hear about it from Sandvine CEO Dave Caputo discuss them in a video embedded after the break.

The general rule of thumb for what counts as a full night’s sleep has been eight hours for as long as anyone can remember, but it’s not an arbitrary number at all. Two studies, one at the University of Pennsylvania and the other at the Walter Reed Research Institute, tested dozens of sleepers and found that sleeping even seven hours a night will slowly add up to a costly sleep debt.

Yale is making high-resolution images from its cultural collections available on a free, open access basis. They’ve started by uploading 250,000 images, with lots more to follow. The collection includes “a small limestone stela with hieroglyphic inscription from the Peabody Museum of Natural History, a Mozart sonata in the composer’s own hand from the Beinecke Rare Book and Manuscript Library, a 15th-century Javanese gold kris handle from the Indo-Pacific collection of Yale University Art Gallery and a watercolor by William Blake.”
As works in these collections become digitized, the museums and libraries will make those images that are in the public domain freely accessible. In a departure from established convention, no license will be required for the transmission of the images and no limitations will be imposed on their use. The result is that scholars, artists, students, and citizens the world over will be able to use these collections for study, publication, teaching and inspiration.
