Collaborate Disseminate
If you’ve never experienced it before, getting turned around on a cloudy day in the woods or getting lost during an event like a snowstorm can be extremely disorienting and …read more Continue reading Hands-Free Compass Uses Haptic Feedback
If someone is at risk of heart failure, it’s important to monitor their vital signs on an ongoing basis. An experimental new wearable is designed to do exactly that, and it takes the form of an electronically endowed belt.Continue ReadingCategory: Medi… Continue reading “Smart” vitals-monitoring belt designed to warn of heart failure
[Angus] at Maker’s Muse recently created a new and tiny antweight combat robot (video, embedded below) and it has some wonderfully clever design elements we’d like to highlight. In particular: …read more Continue reading A Crowned Pulley Keeps Robot’s Treads On Track
Electric bikes have increased in popularity dramatically over the past few years, and while you can easily buy one from a reputable bicycle manufacturer, most of us around here might be inclined to at least buy a kit and strap it to a bike we already have. There aren’t kits …read more
Beer pong is a fun enough game for those of a certain age, but one thing that it lacks is a way of cranking up the difficulty setting independent of the amount of beer one has consumed. At least, that was the idea [Ty] had when he came up with …read more
For a recent event, [MakerMan] was tasked with creating an interactive display that could move back and forth along an image of the Moscow skyline to highlight different points of interest. The end result is certainly gorgeous, but since this is Hackaday, we were more excited to see all the …read more
Haptic feedback is becoming a bigger part of entertainment, with most game controllers for the past 20 years having some form of vibration built in. Now, a German startup is launching the Feelbelt, which adds the element of touch to games, music, movie… Continue reading The Feelbelt adds surround haptic feedback to music, movies and games
If you’ve got a 3D printer, you’re probably familiar with the reinforced belts that are commonly used on the X and Y axis. These belts either come as long lengths that you attach to the machine on either end, or as a pre-sized loop. Traditional wisdom says you can’t just …read more
The toothed belt that turns the camshaft in synchronization with the crankshaft on many motor vehicle engines is something of an under-appreciated component. Unless you are unlucky enough to ave had one fail and destroy your engine, it’s probably something you’ve never given a second thought to outside of periodic service intervals.
For something to perform such a task over so many thousands of miles of motoring it must be made of pretty strong stuff. Even when a belt is life-expired it is still in good physical shape, and [Crispyjones] saw the potential in a used Subaru belt to make …read more
All of us would love to bring our projects to life while spending less money doing so. Sometimes our bargain hunting pays off, sometimes not. Many of us would just shrug at a failure and move on, but that is not [Mark Rehorst]’s style. He tried to build a Z-axis drive for his 3D printer around an inexpensive worm gear from AliExpress. This project was doomed by a gear flaw invisible to the human eye, but he documented the experience so we could all follow along.
We’ve featured [Mark]’s projects for his ever-evolving printer before, because we love reading his …read more
