[ad_1] Researchers at the University of British Columbia leveraged an unusual discovery into ultra-black material made from wood. The deep, dark black is not the result of any sort of dye or surface coating; it’s structural change to the wood itself that causes it to swallow up at least 99% of incoming light. One of […]

[ad_1] Meta’s Quest VR headset recently got the ability to accept and display video over USB-C, and it’s started some gears turning in folks’ heads. [Ian Hamilton] put together a quick concept machine consisting of a Raspberry Pi 400 that uses a VR headset as its monitor, which sure seems like the bones of a […]

[ad_1] We (well, some of us) are complete suckers for things that are both much smaller and much larger than life. And if that thing actually does what its supposed to? Squee! So naturally, we rushed to bring you news of this mini NUC rack designed by [Jeremy Weatherford]. Inspiration comes from a lot of […]

[ad_1] Exercise while you game with this interactive treadmill add-on Arduino Team — September 2nd, 2024 Motion-based controls for games have been around for decades, but even with the latest generation of virtual reality headsets, gaming is still done with relatively limited movement unless one has access to an expensive VR walking/running setup. As an […]

[ad_1] Magnets are pretty nice little tools. [EmGi] has used them in many a cool 3D printed build with great success. But getting them where you want can be really tricky. More often than not, you end up with glue all over your fingers, or the magnets fly out of place, or they stick together […]

[ad_1] Additive manufacturing (AM) has been getting a lot of attention over the years, with its use in construction a recurring theme. Generally this brings to mind massive 3D printers that are carted to construction sites and assemble entire homes on the spot. That’s the perspective with which a recent ZDNet article by [Rajiv Rao] […]

[ad_1] If you follow the world of clean energy, you will probably have read all about the so-called hydrogen future and the hydrogen economy. The gas can easily be made from water by electrolysis from green solar electricity, contains a lot of stored energy which is clean to recover, and seems like the solution to […]

[ad_1] The bulbs inside scanners (before transitioning to LED, anyway) were cold cathode fluorescent tubes that emit a fairly wide bandwidth of light. They were purpose-built to produce a very specific type and shape of light, but [Julius Curt] has taken this in a new, upcycled direction. Instead of just producing light, the light itself […]

[ad_1] We’re guessing most readers can cite things from their youth which gave them an interest in technology, and spurred on something which became a career or had a profound impact on their life. Public engagement activities for technology or science have a crucial role in bringing forth the next generations of curious people into […]

[ad_1] Switch-mode technology has made inverters which take a low DC voltage and turn it into a usable mains voltage within the reach of everybody. But still, there might be moments when a mains supply is needed and you’re not lucky enough to have AliExpress at your fingertips, and for that, here’s [Rulof] with a […]
