There's a lot of hope for displays made from organic light-emitting diodes, a.k.a. OLEDs. They provide better color, higher contrast and are more energy-efficient than the LCDs that currently provide displays for pretty much every television and computer. Many think OLED displays could supplant LCDs within the next five years. But there's a problem: OLEDs are challenging to make, so mass production has been a distant dream.
...until now. The engineers at the equipment company Kateeva have recently launched with what they think is the solution to significantly push OLEDs ahead. And they are doing it with an old technology: ink-jet printers.
Paint restoration is a painstaking and challenging skill to master. But it can also be hugely satisfying.
One of the more challenging tasks is restoring the paint on an old car.
I never thought I'd be interested in car paint correction until I came across Larry Kosilla and his quite extraordinary detailing skills. In this 15-minute video he goes through the entire process of restoring the beat-up paint on a 1958 Porsche Speedster to its original glory.
It's truly shocking to see the difference at the end of the process.
Here's a summary of the cooler tips and geeky tools for those who are considering a paint restoration project for a car.
Trash is a big problem for the environment. Unsurprisingly, the U.S. is the worst (or best, depending on how you look at it) in the world for producing garbage, throwing away two billion tons annually. And while recycled materials have come a long way in helping us to reduce our garbage, there is something else that can be done and this includes an interesting insight into product design.
Turns out that how consumers decide if something is trash or recyclable isn't based on whether the product is, in fact, recyclable. It has more to do with the appearance and size of the product. If it looks like trash, then it will be less likely to be recycled.
Products change during their use. Paper is torn, cans are crumpled. And how form or size changes impacts the likelihood of a product being recycled or just tossed in the garbage. This is the finding from a recent study in the Journal of Consumer Research [PDF].
It was during the mid-90s that Christian Blyt designed a piece of plywood to do the impossible: Bend it into a sinusoidal formation, creating a beautiful panel of corrugated wood without any fracturing. This was for his master's thesis in Finland at Alvar Aalto University. Fast-forward 15+ years, and the product has become a full-fledged company. Launched in 2011, Corelam is now used for furniture, panels, doors, sound-proofing, and other things yet to be invented.
We've written about wood movement and warping before, framing it more as a problem to be fixed instead of a brilliant idea to be captured. So how did Blyt figure out how to bend wood so perfectly into such a thin panel (only 2.4 mm thick)?
These days, Wi-Fi networks are increasingly overloaded and slow, and there's definitely a need for novel solutions for creating wireless connections. You may remember that we looked at "Li-fi," the term coined by German physicist Harald Haas during his TED talk where he outlined the phenomenon of using light bulbs as wireless routers. But that was two years ago--did it die on the vine?
Li-fi development, we're happy to report, is still alive and well. We looked into it and discovered that recently scientists at Fudan University in Shanghai have been pushing the technology forward. They've proven that they can transmit data via light instead of via the typical radio waves, and they've even been able to increase the connection speed to ten times faster than traditional Wi-Fi.
Right now, due to electromagnetic waves in dense cities, there is a limit to the amount of data that can be delivered. But light runs on a much higher frequency than radio. Added plus: You don't need a license to set up a light bulb, as you do when you set up a Wi-fi network over radio waves. What you do need is a way to make the light flicker—so that it can form a signal.
In the lab, the researchers send data to an LED light bulb, just like any LED light you've seen before, and then the light is flicked on/off very rapidly. (In our earlier post we'd wondered if the flickering would give you a headache, but it seems that ultimately, our eyes would only see a steady stream of light. To put that in context, the bulbs you have in your typical office space flicker about 20,000 times per second; the Fudan U. researchers have their bulbs flickering billions of times per second.) A receiver on the computer end (e.g., a camera that detects the flickering light) then translates the flicker pattern into data.
