Collaborate Disseminate
Today, prostheses and exoskeletons are controlled using electromyography. In other words, by recording the electrical activity in muscles as they contract. It’s neither intuitive nor human-like, and it really only …read more Continue reading Magnets Could Give Prosthetic Control a Leg Up
In a kind of reverse twist on the doorbell, [TheStaticTurtle] whipped up a system to mute his computer’s microphone whenever someone opens the door to his room. He lives in France, where the government announced a strict lockdown last Friday. Like many university students around the world these days, he …read more

While we’re still far away from returning to a pre-Corona everyday life, people seem to have accepted that toilet paper will neither magically cease to exist, nor become our new global currency. But back at the height of its madness, like most of us, [Jelle Vermandere] found himself in front …read more

[Peter Jansen] is the creator of the Open Source Tricorder. He built a very small device meant to measure everything, much like the palm-sized science gadget in Star Trek. [Peter] has built an MRI machine that fits on a desktop, and a CT scanner made out of laser-
cut plywood. Needless to say, [Peter] is all about sensing and imaging.
[Peter] is currently working on a new version of his pocket sized science tricorder, and he figured visualizing magnetic fields would be cool. This led to what can only be described as a camera for magnetism instead of light. …read more

I had a small project going on–never mind exactly what–and I needed to detect a magnet. Normally, that wouldn’t be a big problem. I have a huge hoard of components and gear to the point that it is a running joke among my friends that we can be talking about building something and I will have all the parts we need. However, lately a lot of my stuff is in… let’s say storage (again, never mind exactly why) and I didn’t have anything handy that would do the job.
If I had time, there are plenty of options for …read more
