This guy’s ridiculous 40W “laser shotgun” focuses eight beams into one

Now that the Internet has made it easy for just about anyone to get their hands on laser diodes, the DIY laser scene has exploded in the past few years. You wouldn’t believe the beams that people build in their garages these days. Sure, they’re probably dangerous as hell, but there’s just something so appealing about a beam of coherent, monochromatic light — especially if it’s powerful enough to light stuff on fire.

Case in point? This insane 40-watt “laser shotgun” built by laser aficionado, modder, and YouTube personality styropyro. As the inventor readily admits, “there’s no, no good reason for anybody to own something this powerful, but because it wasn’t illegal for me to build, I decided to build it anyway.”

To produce such a ridiculously powerful beam of energy, the “shotgun” uses a 40-watt blue laser diode array. This array doesn’t actually produce a single 40-watt beam at first. Instead, it actually takes eight parallel beams and sends them through a lens, which focuses everything into a single beam — similar to how the choke on a shotgun focuses the pellets into a tighter pattern.

The result is pretty epic. In the video, styropyro shows off how powerful his beam is by pointing it at various objects (balloons, flash paper, a ping pong balls, etc.) — all of which burst into flames after a second or two.

To put the beam’s energy in perspective for you, most conventional laser pointers (the ones people use for to highlight stuff during presentations) usually boast about 2 milliwatts, whereas the highest power laser you can get from Wicked Lasers is just 2 watts. Styropryro’s beam is roughly 20 times as powerful.

If you’re looking for a way to spice up your next PowerPoint presentation, look no further!

There's a scene in Mission Impossible 3 that you might recall. In it, our hero Ethan Hunt (Tom Cruise) tackles the movie's villain, holds him at gunpoint, and forces him to read a bizarre series of sentences aloud.

"The pleasure of Busby's company is what I most enjoy," he reluctantly reads. "He put a tack on Miss Yancy's chair, and she called him a horrible boy. At the end of the month, he was flinging two kittens across the width of the room ..."

Digital Trends’ Top Tech of CES 2023 Awards
Best of CES 2023 Awards Our Top Tech from the Show Feature

Let there be no doubt: CES isn’t just alive in 2023; it’s thriving. Take one glance at the taxi gridlock outside the Las Vegas Convention Center and it’s evident that two quiet COVID years didn’t kill the world’s desire for an overcrowded in-person tech extravaganza -- they just built up a ravenous demand.

From VR to AI, eVTOLs and QD-OLED, the acronyms were flying and fresh technologies populated every corner of the show floor, and even the parking lot. So naturally, we poked, prodded, and tried on everything we could. They weren’t all revolutionary. But they didn’t have to be. We’ve watched enough waves of “game-changing” technologies that never quite arrive to know that sometimes it’s the little tweaks that really count.

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.
[CES 2023] Relumino Mode: Innovation for every need | Samsung
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.
