Don’t get us wrong — we love unique displays as much as anyone. But sometimes we stumble across one that’s so unique that we lack the basic vocabulary to describe …read more Continue reading Simple Design Elevates this Mechanical Dot Matrix Display
The sound a set of machined robot legs tapping on concrete make is remarkable. If for nothing more, the video after the break is worth watching just for this. It’s what caught my attention when I first wandered by the Mech Warfare area at Maker Faire, as one of the …read more

You might think that tiny autonomous drones that can be fired out of a standard 40 mm grenade launcher for rapid deployment would be the kind of thing the military would love to get their hands on. Which is true, of course, and a number of companies are working on …read more

3D printing is well-suited to cranking out tank tread designs, because the numerous and identical segments required are a great fit for 3D printing’s strengths. The only hitch is the need for fasteners between each of those segments, but [AlwynxJones] has a clever solution that uses plentiful hard plastic spheres …read more

If you ever needed evidence that gamers are some of the most dedicated individuals in all of fandom, then look no further than this fantastic 3D printed recreation of the “Pulse Pistol” as featured in the immensely popular “Overwatch”. Built by the guys at [Danger Doc], this replica doesn’t just look the part, it’s also a fully functional Airsoft gun. In the detailed build video after the break, the year-long design and construction of the gun is broken down for your viewing pleasure.
Because the end goal was to make something that looked as though it came from the …read more

In the eternal struggle for office dominance, the motion-tracking Airsoft/Nerf/whatever, the autonomous turret seems to be the nuclear option. [Aaron] and [Davis] built a motion-tracking turret that uses openCV to detect movement, before hitting a relay to trigger the gun.
There’s a Raspberry Pi controlling a Logitech C210 Pi-compatible webcam, with a stepper hat for the Pi controlling two NEMA steppers that aim the gun. The design is simple but elegant, with a rotating base and an assembly that raises and lowers the weapon.
The openCV intrigues us. We want to see a openCV-powered turret with color detection, so your …read more
