A team from the University of Sichuan won the Red Dot Design award for a concept design called "Lumigrid" -- a bike-light that projects a grid on the ground ahead of the rider, making terrain irregularities easy to spot:
Lumigrids can project a grid onto the ground. On a flat road surface, the grid will consist of standard squares. On a rough road surface, the grids will deform accordingly. By observing the motion and deformation of the grids, the rider can intuitively understand the landforms ahead. In addition, the luminous grids can make it easier for nearby pedestrians and vehicles to notice the bicycle, reducing the likelihood of collision.
Lumigrids can be fixed onto the bicycle’s handlebars. Its power is supplied by either an internal battery or by the rotation of the bicycle’s wheels. It has only one button so that the rider can easily use it while riding. The first press will turn on the power, the second press will change the mode of projection, and holding the button down for two seconds will turn the power off. Lumigrids has three modes with different grid sizes that can be used to adapt to different situations: normal mode (140x180mm), high-speed mode (140x260mm), and team mode (300x200mm)."
This dongle allegedly converts “household” — i.e. 110v AC power — to 3.5mm. It’s misdescribed and is for photographic use (if it were intended to be jammed in the mains, the prongs would have holes) but it makes me think a splendid purpose would be for the gadget mafia to use to issue death threats […]
At Reddit, mtietje posted this remarkable photo of their lockdown project: an iPad stand made using an old Macintosh SE/30. The display size is perfect for the 9.7″ iPad, and now that iPadOS can use mice they work much better as “normal” computers. Se/30 shells turn up on eBay now and again. One’s there now […]
A $350 USB device claiming to block 5G radio signals is just a cheap unbranded thumbdrive, report security researchers. The makers of the “5GBioShield” claim their USB stick can block electrical waves through a “proprietary holographic nano-layer catalyst” technology. It purportedly does this by “balancing” all the existing radiations around you to create a protective […]
Game engines aren’t just the lifeblood of the video game industry. They may soon be the lifeblood of Hollywood. Since emerging in the late ’90s, the Unreal game engine has quickly become one of the world’s foremost tools for game creators. Now, Disney’s hit Star Wars spinoff series The Mandalorian is using Unreal as well. […]
Apple AirPods have become the default earbuds beloved by millions. Unfortunately, they also cost $159, so it’s no surprise that since they were first introduced in 2016, companies have battled to produce comparable headphones at a lower price. The UK-designed and engineered Veho STIX true wireless earphones may have cracked that particular problem, striking a […]
Instagram isn’t just for tweens and foodies. In fact, the image-heavy platform not only wants to mint new Instagram influencers — it also wants to make them rich. In the last few weeks, the company announced ad revenue sharing on IGTV videos, special badges you can buy from your favorite accounts through Instagram Live, merchandise […]
