When it comes to transmissions, a geared continuously-variable transmission (CVT) is a bit of a holy grail. CVTs allow smooth on-the-fly adjustment of gear ratios to maintain a target speed …read more Continue reading Behold a Geared, Continuously Variable Transmission
E-bikes combine a bicycle with a big lithium battery, a speed controller, and a motor. What you get from that combination is simple, efficient transportation. [Tom Stanton] wanted to build …read more Continue reading Electric Bike Uses No Electronics, Weird Motor
This holiday season, [Chaz] wanted to continue his family’s tradition of enrobing a little bit of everything in dark chocolate, and built an improved, rotating chocolate-coating machine. You may remember …read more Continue reading Chocolate-Coating Machine Mk. 2: the Merry-Go-Round
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
