      Volumetric LED candle looks the same from any angle—and looks like amazing work

    The latest device crafted by the prolific maker going by mitxela comprises an LED matrix board, "a bunch of electronics" underneath it, an infrared sensor, a coin battery, and the motor from a CD drive. It's a deceptively simple bill of goods for a rather elegant DIY project the size of a tea light candle.

    Typical volumetric displays are tricky things, given the need to send data and power to rapidly spinning things. Mitxela's solution: make everything spin, including the battery. Creeping up on the infrared sensor with his finger, mitxela coaxed the tiny spinning board to create collapsing stars, pouring liquid, and the candle flames for which it was originally designed.

    A video that only barely captures the volumetric look of this LED display, but it still looks pretty neat.

    "I won't deny, this is a very satisfying result for what was a hastily thrown-together prototype," mitxela says in the video. "I wasn't expecting it to work at all." The next version will have more LEDs, and they'll be better-centered; right now, the LED matrix backplate is on the center line, not the LEDs themselves. Since the LEDs illuminate twice during each revolution, having them exactly centered improves the clarity of the resulting image.

      The 2023 Hyundai Ioniq 6’s interior lighting might cheer you up

    The annual auto show is underway in Los Angeles this week, and Hyundai used the event to make the North American debut of its next electric vehicle, the Ioniq 6 . It's a curvaceous sedan, one that looks better in person than on a two-dimensional screen, and when it goes on sale in 2023, it will be yet another example of the lighting revolution that has brightened up automotive interiors, and perhaps can brighten a driver's mood.

    We've written before about how LEDs have been embraced by designers crafting the exteriors of new cars. Freed from the old confines of inefficient bulbs and large, often round reflectors, today new cars and trucks are decorated by strips and slashes of yellow and red daylight running lights, with headlamps that light brighter and throw farther down the road. If a car's headlights are its face—and humans are good at seeing faces in things—then new lighting technology has given our vehicles a new range of expressions.

    Vehicle interiors are becoming more expressive, too. LEDs have taken over from incandescents here, bringing color along for the ride. The Ioniq 6, for example, boasts 64 different hues to choose from, backlighting the door cards and the dashboard.
