Permanent magnets aren’t typically switchable. They’re always doing their magnet thing. However, if you align them with a bunch of other magnets in just the right way, you can create a …read more Continue reading You Can 3D Print Yourself Some Simple Magnetic Switches
If you have a late-model laptop, you’ve probably seen how the chargers magnetically snap into place. In theory, this should be easy to recreate for your own purposes. But why …read more Continue reading Print Your Own Magnetic Connector
Most electromagnetic actuators are rotating motors, or some variation on the theme, like servos. However, it’s possible to do linear actuation with electomagnetics, too. [Adrian Perez] demonstrates this with Linette, …read more Continue reading Electromagnetic Actuator Mimics Muscle
Cardboard is a surprisingly durable material, especially in its corrugated form. It’s extremely lightweight for its strength, is easy to work, can be folded and formed into almost any shape, …read more Continue reading Swapping Vinyl for Cardboard with this ESP32 Turntable
Dice are about the simplest machines possible, and they’ve been used since before recorded history to generate random numbers. But no machine is so simple that a little needless complexity …read more Continue reading Spinning Magnets Do Your Dice Rolling for You
It is a common grade school experiment to wind some wire around a screw, power it up, and watch it pick up paper clips or other ferrous materials. It is …read more Continue reading Sort of Electromagnet Attracts Copper, Aluminum
Here at Hackaday, we feature all kinds of projects, and we love them all the same. But some projects are a little easier to love than others, especially those that …read more Continue reading 3D Printing Improves Passive Pixel Water Gauge
If you want a strong magnet, the obvious answer is to buy one. However, for a variety of reasons, you might want to combine several smaller magnets. There are a …read more Continue reading Halbach Array Makes Magnets Strong, Weak
The famous hoverboards of Back to the Future haven’t quite gotten here yet, but that hasn’t stopped anyone with a unique personal vehicle from using the name any time they …read more Continue reading Hoverboard Rides on Eddy Currents
When you think of a bicycle and an Eddy, you’d be forgiven for thinking first of Eddy Merckx, one of the most successful competitive cyclists to ever live. But this …read more Continue reading A Bicycle Powered By A Different Kind Of Eddy
