Volumetric displays are simply cool. Throw some LEDs together, take advantage of persistence of vision, and you’ve really got something. [Nick Electronics] shows us how its done with his neat …read more Continue reading Small Volumetric Lamp Spins at 6000 RPM
In general, the simpler a thing is, the better. That doesn’t appear to apply to engines, though, at least not how we’ve been building them. Pistons, cranks, valves, and seals, …read more Continue reading A Wobble Disk Air Motor with One Moving Part
Self-balancing devices present a unique blend of challenge and innovation. That’s how [mircemk]’s project caught our eye. While balancing cubes isn’t a new concept — Hackaday has published several over …read more Continue reading DIY 3D-Printed Arduino Self-Balancing Cube
For getting around on most surfaces, it’s hard to beat the utility of the wheel. Versatile, inexpensive, and able to be made from a wide array of materials has led …read more Continue reading Mobile Coffee Table Uses Legs to Get Around
We don’t know how you feel when designing hardware, but we get uncomfortable at the extremes. High voltage or current, low noise figures, or extreme frequencies make us nervous. [Orion …read more Continue reading An Open Source 6kW GaN Motor Controller
Can you build a car that travels farther than you push it? [Tom Stanton] shows us that you can, using a capacitor and some nifty design tricks. [Tom]’s video shows us …read more Continue reading You Can Build A Little Car That Goes Farther Than You Push It
Chinese drone and imaging multinational DJI has announced its entry into the ebike drive system market, along with the launch of a new ebike brand and the first electric mountain bike to sport Avinox power.Continue ReadingCategory: Bicycles, TransportT… Continue reading DJI ebike rips electric motor tech out of the sky and into the dirt
As some entities identify new (or at least overlooked) sources to meet the growing demand for rare earth materials, others are looking toward new tools. UK deep-tech company Materials Nexus announced on Tuesday that it has designed a new rare-earth-fre… Continue reading AI discovers new rare-earth-free magnet at 200 times the speed of man
Earlier this month, we featured a Whale Design propeller that looked to nature for improved efficiency. Switzerland’s ABB Marine has also been inspired by “the dynamic motions of a whale’s tail” for its multi-blade Dynafin propulsion concept.Continue R… Continue reading ABB’s cycloidal marine propellers: Efficient thrust in any direction
