Tech Today w/ Ken May

Another day, another step closer to quantum dot reality. Today, Nanosys unveiled its new Quantum Dot Enhancement Film (QDEF), marking the first time that the nanotechnology is available for LCD manufacturers. According to the company, its optical film can deliver up to 60 percent of all colors visible to the human eye, compared with the 20 to 25 percent that most displays offer. To create QDEF, Nanosys’ engineers suspended a blend of quantum dots within optical film and applied it to a blue LED, which helped get the nanocrystals excited. Once they started hopping around, the dots emitted high-quality white light and a rich, wide color gamut, without consuming as much power as white LED-based materials. No word yet on when we can expect to see QDEF in consumer displays, but Nanosys claims that the film is “process-ready” and easy for manufacturers to integrate. For now, you can amuse yourselves by comparing the two frogs pictured above and guessing which one is covered in quantum dots. Full PR after the break.

When I was a kid I planted a tree that grew over the rooftop of my house. At the time I thought that was pretty cool, but now I have seen this great gallery of The Strangest Trees on Earth, which you will agree are pretty strange. See full gallery at the link.

Sometime last week we quietly turned on our latest project. Plansharing: Collaboration for Architects, Engineers, Designers, and their clients is a basecamp like tool for CAD. The idea is to make the communication around plans and large projects clear and simple. We focused on a single feature, marking up plans. You can view arbitrarily complicated CAD files without flash, plugins, or installed software. How do we do it? We copy the way google maps and open street maps work, making tiles instead of rendering full vector images. Last year I built a beach cabin , and in the process i realized that there was something really broken in the communication process between architects, builders, and their clients. To make change requests, talk about what needed to be done, we either had to travel for a face to face meeting, or mark up pdf’s of the plans. Some hacking, brainstorming with Diego , some tweaking, mockups, running code, and now we’ve got plansharing . It’s very focused on the primary task, discussions around plans, viewing changes, communicating visually online what’s happening in CAD files. We’ll be flushing it out, building it in to a collaboration tool. It’s not done, it’s not refined or polished, but it mostly works and we think we’ve got enough of an app to be useful. We’re looking for beta testers. Know somebody who works with CAD, or is getting their kitchen remodeled? Give plansharing a try and tell us what you think.

Ninety six minutes. Eleven shocks by defibrillator. Two dozen rescuers pounding his chest in shifts to bring vital oxygen to his limp body. A helicopter, even. That’s what it took to revive 54-year old Howard Snitzer this month. Oh, and a little celebrated thing called a capnography machine that let everyone know that he was still capable of being brought back from the brink of death. More

Go ahead and drive your SUV to the plastic factory: The French have discovered the first habitable planet in another solar system. It’s called Gliese 581d, and it’s a mere 20 light years away. More

In the run-up to the releases of the Volt and the Leaf, there was some talk making the rounds that the designers were having some trouble deciding what noise these new cars should make. After all, they’re naturally almost silent, and this presents a serious risk not just to unwary pedestrians but to also to blind people, wildlife, and of course other cars.

The question is whether you make EVs sound like other cars by simulating engine noise, or do you take this chance to give them an entirely new and perhaps more practical and customizable noise?

Some cars, of course, have a distinctive noise that results naturally from the mechanics of the engine and exhaust. Car designers can make their own noise now, even make your Leaf sound like an old Mustang — but should this noise be regulated, and if so, on what level?

Manufacturers and designers are testing out different sounds, from a UFO noise to the sound of a baseball card flapping against bike spokes, attempting to suss out which exactly produces the most awareness without becoming grating. The BBC has a nice video here with some of the noises being looked at by UK researchers.

They’re even simulating intersections with dozens of such vehicles and seeing how certain sounds would interact. Hey, you don’t roll something out to ten thousand vehicles without doing a little checking around, right?

I’m torn on the subject. Obviously there’s a line that needs to be walked between good taste and safety, but there are lots of unanswered questions as well. What about special sounds for certain types of vehicles, or user-selectable sounds? I want mine to sound like a Transformer transforming, all the time.

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.
