LED

  • Like many people at this time of year, Leo Currie has a decorated tree in his living room. But this one is a bit different, as anyone can open an online landing page and take control of the lights snaking through the branches.
  • The Capital Cinema in Beijing's Xicheng district has been fitted out with a new 3D-ready Onyx Cinema LED screen – and it's 1.4 times wider than those which have come before.​
  • ​If you want to brighten up your playing, you can have LEDs installed in the neck, but what about all that idle space on the body? Sparkfun's Andy England was recently asked to light up one of three custom guitars, and has now modified it to play video animations on the body itself.​
  • Currently, if you want to measure someone's blood oxygen levels, you have to use an oximeter that clips onto their finger. An experimental new system, however, is able to check those levels anywhere on the body – and that could mean big things for the field of medicine.
  • ​Instrument modder Frank Piesik has combined 3D printing, electronic hackery and touch sensing to create the ElektroCaster that bridges the gap between traditional guitars like a Telecaster and full-on electronic sound makers like the (no longer in production) Kitara.​
  • Self-driving cars can't make eye contact to signal their intentions, so Volkswagen is testing several systems that turn a car into an interactive information display to project information onto the road for drivers and display interactive information to other road users.
  • In a world bombarded by screens constantly blasting ads and visual noise, a team of artists and designers wondered if glasses could be created that can black out all those invasive messages. After a year of research and prototyping the IRL Glasses are now launching on Kickstarter.
  • ​Studies have already shown that by irradiating bald skin using red lasers, hair follicles can be stimulated into growing new hair. Unfortunately, though, such laser setups are large, cumbersome and energy-inefficient. With that in mind, scientists have developed a wearable LED photostimulator.
  • Not every cyclist can stow away their bikes in a garage. Apartment dwellers don't have much space indoors, but won't want to leave their bikes outside either. Italy's Vadolibero has combined a vertical bike rack with a floor lamp for a stylish solution to cycle storage in the home.
  • A year ago, Philips Lighting (now called Signify) announced results of a study which showed that its ClearField red LED lighting didn't disrupt the behaviour of bats – unlike traditional streetlights. Now, the Dutch town of Zuidhoek-Nieuwkoop has become the first place to use the system.
  • The field of optogenetics is all about using light to stimulate cells in the body. Now, researchers from Flinders University have used the technique to shine a light where the Sun don’t shine, stimulating nerves in the gut to relieve chronic constipation.
  • ​Following LEDs on a guitar's neck is a great way to learn playing basics fast. Late last year Fret Zealot started shipping an LED learning sleeve out to Kickstarter backers, one that positioned lights right up to the 15th fret. Now a bass version has launched on the popular crowdfunding platform.​
