Collaborate Disseminate
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
We’ve covered a number of projects that assist makers who need to fill orders for their small businesses, or kitting. [Helmke] has sorted thousands of pieces of hardware that they …read more Continue reading Dispense 60 Bolts in 2.3 Seconds
When [Michael Rechtin] learned about Radial Vector Reducers, the underlying research math made his head spin, albeit very slowly. Realizing that it’s essentially a cycloidal drive meshed with a planetary …read more Continue reading Radial Vector Reducer Rotates At Really Relaxed Velocity
3D printed gearboxes are great for experimental designs, but due to roughness and inaccuracies in the printed surfaces, they can wear quickly and be rather noisy. As a possible alternative, …read more Continue reading Magnetic Gearbox Can Go Fast But Not Hard
Affordable brushless motors are great for a variety of motion applications, but often require a gearbox to tame their speed. [Michael Rechtin] decided to try his hand at designing a …read more Continue reading Stackable 3D-Printed Gearbox For Brushless Motor
It sounds like a rhetorical question that a Midwestern engineer might ask, something on the order of ‘can you fix this bad PCB spin?’ [Tom Stanton] sets out to answer …read more Continue reading Can A Drone Push A Bike?
A press is a useful thing to have, whether you like destroying stuff or you simply want to properly install some bearings. [Retsetman] decided to build one from scratch, eschewing …read more Continue reading 3D-Printed Gear Press Can Squash Stuff, Kinda
When [Morley Kert] laid eyes on a working time card-punching clock, he knew he had to have it for a still-secret upcoming project. The clock seemed to work fine, except …read more Continue reading Printable Fix for Time Card Clock Has Owner Seeing Red Again
When it comes to making gearboxes, 3D printing has the benefit that it lets you whip up whatever strange gears you might need without a whole lot of hunting around …read more Continue reading Resin-Printed Gears Versus PLA: Which Is Tougher?
A cycloidal gear drive is one of the most mesmerizing reduction gears to watch when it is running, but it’s not all just eye-candy. Cycloidals give decent gearing, are relatively …read more Continue reading Do You Need a Cycloidal Drive?
