Want to 3-D print your own neopixel LED display TV? Now you can

Between all the telescopes, rocket engines, and body parts that people are printing these days, there are so many crazy additive manufacturing projects in the world that a 3D-printed TV hardly seems noteworthy at this point. But while we might not normally bat an eye at this kind of thing, Teleavia Matrix is different.

Unlike most complex 3D-printed objects, which require expensive industrial-grade printers, this retro-style LED-powered TV can actually be printed on just about any consumer-grade 3D printer on the market. You can make the entire thing with just a couple hundred bucks in parts — and a 3D printer, of course.

Don’t toss your Vizio in the trash quite yet though. The Teleavia Matrix isn’t going to replace your regular TV anytime soon. It’s really more of a novelty item than a full-on TV, but that doesn’t make it any less awesome. According to its creator David Choi, “the name and design are a tribute to the Art Deco, Teleavia Panoramic 111, a beautiful French television set released in 1957. The Panoramic 111 was a High Definition television capable of 819 lines, which is considered HD even today.”

While the original set may very well have been “high def,” Choi’s 3D-printed version isn’t. To generate pictures, the Teleavia Matrix uses a 32×16 inch LED NeoPixel matrix (hence the name), so it’s about as low-res as it gets. That said, when you consider the fact that it’s only got 512 giant pixels to work with, the images it’s capable of creating are pretty impressive.

The magic behind the LED matrix is a special NeoPixel driver (called FadeCandy) that enables dithering, or creating additional colors and shades from an existing palette by interspersing pixels of different colors. “Dithering results in higher quality images for an LED matrix,” Choi explained in an interview. “Since we’re restricted to a fewer number of pixels, image quality drops, but dithering essentially helps smooth out the image colors for our eye, helping to reproduce the detail that would be lost otherwise.”

You can download the instructions and start building the Teleavia Matrix right now on Thingiverse — but it might be wise to hold off for a bit. Choi says it’s still a work in progress, and he’s still got a few wrinkles to iron out of the design before it’s ready for primetime. Plus, right now the screen is just a prototype made from cardbaord, though Choi expects to finish the design files for the screen soon.

Sony Bravia X95L mini-LED vs. TCL QM8 QLED: The best LCD TV and the one you should buy
Sony X95L vs TCL QM8

This comparison puts Sony’s flagship mini-LED TV, the Sony X95L, versus the TCL QM8, TCL’s best mini-LED TV. I’ve called the Sony X95L the best LCD TV I’ve ever tested, and I’ve said that the TCL QM8 might just be the best value in TV right now, despite a few notable quirks.

But is this really a fair fight? There’s more than $2,000 separating these 85-inch TVs. In terms of price, Sony’s X90L is a closer match to the TCL QM8. But in terms of technology and the fact that these are the best LCD TVs on offer from Sony and TCL, I think this versus will be fun — never mind whether it makes a lot of sense.

Apple Vision Pro brings TV, 3D movies to a massive, 100-foot-wide screen
A person is watching a movie using the Apple Vision Pro.

As expected, at WWDC 2023, Apple unveiled its first mixed-reality headset, the Apple Vision Pro. Among its many amazing features, Apple demonstrated what it will be like to watch TV and movies on the device, and the results look impressive. The headset is expected to be available in 2024, for $3,500.

Apple showed how the Vision Pro will let you open a virtual screen within your field of view that can be as small or as big as you want -- virtually speaking. At its largest size, Apple claims the screen can occupy a relative width of 100 feet.

3D printed cheesecake? Inside the culinary quest to make a Star Trek food replicator

Along with jetpacks, holograms, and universal healthcare, one of the great unfilled promises of the Star Trek-style future is the food replicator. Few concepts hold more sway over both the keen foodies always on the lookout for the latest trend in dining and those of us who can barely be bothered to put a frozen pizza in the oven than a box in your home which can create any meal you desire.

You press a button, and the machine whirs and beeps and creates the delicious dish of your choosing, no tedious chopping or marinating or pan-searing required. It’s an idea far too good to be true — but we might be one step closer to this paradisiacal utopia than you think.
How to 3D print a cheesecake
Researchers from Columbia University recently managed to 3D-print a cheesecake, in a process that is exactly as delightful as it sounds. They detailed their discoveries in an article in npj Science of Food, and we spoke to lead author Jonathan Blutinger to learn how they did it.
