3D-Printed Working Engine
Alexander worked in his workshop for years on a simple goal: to turn spools of everyday filament into a workable internal combustion engine. That is, anything with a few hundred horsepower to get the aging bones going. His third generation of this made-from-scratch engine, known as the AP3 Carbon D125, has recently met that target. The new design surrounds a 125cc single-cylinder four-stroke engine, which is commonly found in scooters.

DIY Custom Multiview Stereo Projection 3D Fog Scenes
Maker ‘Ancient’ recently worked on a project that transforms standard fog into a small stage for 3D models. So you stand in front of it and see this green ghost, also known as Slimer from Ghostbusters, floating around in mid-air. You go to one side, and the perspective refreshes fluidly, as if the ghost is actually floating about in there. There is no need for special glasses or anything like that.

LG OLED evo W6 TV
Engineers squeezed a high-end TV into a panel that is only 9 millimeters thick. LG calls it the OLED evo W6, and once hanging, it truly lives true to its “wallpaper” label. Two flat mounting pads and a couple of screws hold the screen tightly against the wall, leaving no obvious gaps. A ultra slim power board at the back connects to the nearest outlet, and that’s it. What about the weighty electronics? They remain out of sight somewhere else.

Astrobotic Rotating Detonation Rocket Engine Hot Fire Record Test Run
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 Outdoor Solar String Lights
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.
