Electric bikes may be taking the world by storm, but the world itself doesn’t have a single way of regulating ebikes’ use on public roads. Whether or not your ebike is legal to ride on the street or sidewalk where you live depends mostly on… where you live. If you’re …read more

Autonomous mobility pods of the future could gain themselves exceptional tight-space maneuvering capabilities if Protean’s 360-degree integrated wheel systems come to fruition. Each one packs steering, suspension, motors and pneumatic ride-height adjustment into a single unit.

“Gravel bikes” are becoming increasingly popular, as they combine some of the toughness of mountain bikes with the speed of road bikes. Given that they travel on dirt trails and unpaved roads, though, some suspension might be good – and that’s what Cannondale’s new Topstone Carbon offers, in a novel fashion.

Scammers are now using the threat of channel suspension to coerce YouTube content creators into meeting their demands and sending over money. These digital attackers are specifically targeting YouTube’s policy infringement system through which us… Continue reading Scammers Threatening YouTube Content Creators with Channel Suspension
Sometimes you encounter projects that defy description, as is the case with this one. So perhaps it’s best to start with what this project is NOT. It is not a sphere. It is not a perpetual energy device. It has neither a sloppy build nor a slapdash video. This IS a motorized rhombicuboctahedron that is a well-explained with high-quality parts and loving attention to detail by [Wolfram Glatthar]. At its heart is an exercise in building a moving device with the barest minimum of friction. Without no grinding in the mechanism, the electronics will probably wear out first. Low friction …read more

Tanks are highly capable vehicles, with their tracks giving them the ability to traverse all manner of terrain at speed. An important part of a tank is its suspension setup, without which its treads are far less capable. When [Ivan] began work on his 3D printed tank project, he couldn’t ignore the comments. His tank would need a suspension system.
The tank build itself is impressive, consisting almost entirely of 3D printed components held together with off-the-shelf bearings and threaded rod. [Ivan] retools the tank from the beginning to fit a pivoting suspension system which is surprisingly simple in its …read more

Who doesn’t love magnets? They’re functional, mysterious, and at the heart of nearly every electric motor. They can make objects appear to defy gravity or move on their own. If you’re like us, when you first started grappling with the refrigerator magnets, you tried to make one hover motionlessly over another. We tried to position one magnet over another by pitting their repellent forces against each other but [K&J Magnetics] explains why this will never work and how levitation can be done with electromagnets. (YouTube, embedded below.)
In the video, there is a quick demonstration of their levitation rig and …read more

[Josh] is replacing the springs in his car’s suspension. He wanted to know the travel rates of these springs, but apparently, this is a closely guarded trade secret in the industry. One company did manage to publish the spring rates, but they weren’t believable. Instead of taking this company’s word, [Josh] built a spring tester.
The theory behind a spring tester is pretty simple: apply a force to a spring, measure it, then measure how much the spring has traveled. Or compress a spring an inch or so, measure the force, and compress it some more. Either gets you the …read more
