CNC cutting machine can slice foam into any shape you desire

P400 - Kickstarter Campaign 2017
What does the overwhelming number of CNC (Computer Numerical Control) tools available on the market say to you? If your answer is that “there are clearly too many,” stop reading now. If, on the other hand, your response is “people obviously like them; let’s see some more,” then you’re in luck!

That’s because a new high-precision cutting machine has just arrived on Kickstarter — and it’s bound to be of interest to many of you would-be “makers” out there. Called P400, this is a high-precision desktop cutter with a difference, since the material it uses to slice and dice isn’t your usual wood or plastic, but rather cheap and normally disposable polystyrene.

“We are in a period in which 3D printing leads the market, but we strongly believe that there are a lot of applications in the CNC world that are equally interesting and useful,” co-creator Flavio Prattico told Digital Trends. “Polystyrene is a really poor material, but it is really easy to work, and with few post-processing, you can obtain awesome objects. This is why we love it! [By ‘poor’], I mean it is cheap, not nice as it is — like wood — and in people’s minds is a material just for packaging.”

As with other CNC machines, users create the shape they want to cut out on a computer. The P400 machine then goes to work with its tiny blade by cutting out the pattern exactly. It’s very fast, and impressively accurate — meaning that you’ll be able to not just cut straightforward shapes but also more detailed one such as puzzles, stencils, or even individual words and letters.

The advantage of polystyrene is that, while it’s far from the world’s most durable material, its cheapness means that you can create your works without spending much in the way of capital.

P400 is currently available to pre-order on Kickstarter, with prices set at 299 euros ($316). Shipping is set for September, and supplies are limited.

Digital Trends’ Tech For Change CES 2023 Awards
Digital Trends CES 2023 Tech For Change Award Winners Feature

CES is more than just a neon-drenched show-and-tell session for the world’s biggest tech manufacturers. More and more, it’s also a place where companies showcase innovations that could truly make the world a better place — and at CES 2023, this type of tech was on full display. We saw everything from accessibility-minded PS5 controllers to pedal-powered smart desks. But of all the amazing innovations on display this year, these three impressed us the most:

Samsung's Relumino Mode
Across the globe, roughly 300 million people suffer from moderate to severe vision loss, and generally speaking, most TVs don’t take that into account. So in an effort to make television more accessible and enjoyable for those millions of people suffering from impaired vision, Samsung is adding a new picture mode to many of its new TVs.

Relumino Mode, as it’s called, works by adding a bunch of different visual filters to the picture simultaneously. Outlines of people and objects on screen are highlighted, the contrast and brightness of the overall picture are cranked up, and extra sharpness is applied to everything. The resulting video would likely look strange to people with normal vision, but for folks with low vision, it should look clearer and closer to "normal" than it otherwise would.
Excitingly, since Relumino Mode is ultimately just a clever software trick, this technology could theoretically be pushed out via a software update and installed on millions of existing Samsung TVs -- not just new and recently purchased ones.

AI turned Breaking Bad into an anime — and it’s terrifying

These days, it seems like there's nothing AI programs can't do. Thanks to advancements in artificial intelligence, deepfakes have done digital "face-offs" with Hollywood celebrities in films and TV shows, VFX artists can de-age actors almost instantly, and ChatGPT has learned how to write big-budget screenplays in the blink of an eye. Pretty soon, AI will probably decide who wins at the Oscars.

Within the past year, AI has also been used to generate beautiful works of art in seconds, creating a viral new trend and causing a boon for fan artists everywhere. TikTok user @cyborgism recently broke the internet by posting a clip featuring many AI-generated pictures of Breaking Bad. The theme here is that the characters are depicted as anime characters straight out of the 1980s, and the result is concerning to say the least. Depending on your viewpoint, Breaking Bad AI (my unofficial name for it) shows how technology can either threaten the integrity of original works of art or nurture artistic expression.
What if AI created Breaking Bad as a 1980s anime?
Playing over Metro Boomin's rap remix of the famous "I am the one who knocks" monologue, the video features images of the cast that range from shockingly realistic to full-on exaggerated. The clip currently has over 65,000 likes on TikTok alone, and many other users have shared their thoughts on the art. One user wrote, "Regardless of the repercussions on the entertainment industry, I can't wait for AI to be advanced enough to animate the whole show like this."

4 simple pieces of tech that helped me run my first marathon

The fitness world is littered with opportunities to buy tech aimed at enhancing your physical performance. No matter your sport of choice or personal goals, there's a deep rabbit hole you can go down. It'll cost plenty of money, but the gains can be marginal -- and can honestly just be a distraction from what you should actually be focused on. Running is certainly susceptible to this.

A few months ago, I ran my first-ever marathon. It was an incredible accomplishment I had no idea I'd ever be able to reach, and it's now going to be the first of many I run in my lifetime. And despite my deep-rooted history in tech, and the endless opportunities for being baited into gearing myself up with every last product to help me get through the marathon, I went with a rather simple approach.
