Astrobotic engineers went all out on their Chakram prototypes, doing a series of hot-fire tests that dwarfed anything previously done with this type of hardware. Two rotating detonation engines together clocked over 470 seconds of operation throughout eight runs at the Marshall Space Flight Center in Alabama, one of which lasted a whole 300 seconds without any hitches, and the entire time each engine delivered a solid 4,000 pounds of thrust as steady as can be.
Govee’s Outdoor Solar String Lights have just launched, and they’re already making waves across social media. The string itself is 34 feet long and has eight extremely flexible bulbs that may be hung over a fence, a tree branch, or the border of your patio. A secondary 6 watt solar panel clamps on and may be tilted to maximize sun exposure while the lights are in place.
Hyundai just revealed its IONIQ V sedan at the Beijing Auto Show, and the new vehicle shares the elegant design of the Venus concept that inspired it. The engineers and designers stayed fairly near to the wild lines that made the concept so appealing, releasing an electric machine designed from the bottom up with Chinese buyers in mind.
Waveshare engineers used a basic Raspberry Pi 4 or 5 to build a complete portable desktop. What they come up with is PocketTerm35, something that fits in the palm of your hand, boots up a full-fledged Linux system right away, and does so with a display you can tap and a keyboard you can actually hammer away on, eliminating the need to look for function keys.
Porsche has just revealed the Cayenne Coupe Electric, which sits alongside the petrol and plug-in hybrid variants in the lineup and is aimed directly at drivers looking for significant performance as well as a lot of comfortable luxury. The new coupe, available in three trim levels, combines Porsche’s quick handling, plenty of range potential, and all the practical amenities you’d expect from a car that’s just as happy to deal with the daily grind as it is to take you to the limits in serious style.
Yesterday marked the end of a long wait for AI enthusiasts who have been watching every development coming out of the Chinese lab. DeepSeek has launched a pre-release version of its V4 model, complete with open weights, for anyone to download and run on their own hardware, representing a significant step forward for the community. The release includes two separate flavors that provide top-tier capabilities without the usual prohibitively high entry barriers.
Back in the early 1980s, Radio Shack sold a variety of gadgets that caught the eye of both curious children and tech enthusiasts. Among those goods was Gobble Man, a small handheld game that placed maze chases directly into your palms years before the larger portable consoles that came later. Bandai first released this in Japan during 1981 as a game known as Packri Monster. Tandy then scooped it up, licensing the design for its US stores before selling it as Gobble Man in 1983. To add to the confusion, Tandy sold the exact same units under the titles Hungry Monster and Ogre Eater.

Dummy units of the iPhone 18 Pro series and a super-sleek new foldable Ultra model have leaked, giving people a good idea of what Apple has in store for the September debut. Case makers received these prototypes based on the final CAD files, thus they are quite similar to the production hardware in terms of shapes, sizes, layout, and so on. Owners of current phones will notice some little but important changes rather than a complete redesign, with one exception that stands out.
Years of painstaking effort at NASA’s Goddard Space Flight Center have finally paid off, with the Nancy Grace Roman Space Telescope now fully completed. Last November, the engineers were able to connect the two main portions, and now that the observatory has been polished and tested, it is sitting pretty in the site’s largest clean room. Next up is shipping out to Florida’s Kennedy Space Center in June, where a SpaceX Falcon Heavy rocket will launch into space as early as September, an incredible 8 months ahead of schedule and under budget.
Years ago, a teenager became obsessed with basic high-voltage gear and dreamed about something bigger. Fast forward to now, and the maker known as Schizo, has just finished building a full-sized handheld device that emits a strong electromagnetic pulse.
