In lieu of high-explosives, an exploding wire circuit can make for an interesting substitute. As [Hyperspace Pirate] demonstrates in a recent video, the act of pumping a lot of current very fast ...

Soft copper wire: 22 gauge (wire diameter 0.6mm): 3 pieces 7cm (about 3 inch), 2.5cm (1 inch) 28 gauge (wire diameter 0.3mm): 20cm (8 inch) Spherical stone with a diameter of 6mm This video is re-edit ...

[Steven’s] at it again with another cool science experiment that isn’t too difficult to do. This time he’s made himself a Nitinol wire inchworm, which actually moves across the table when you apply a ...

If you’ve ever looked carefully at a full glass of water or a water droplet, you may have noticed that the water forms a thin, stretchy layer at its surface. This phenomenon is called surface tension.

Any robot that moves needs actuators—motors that move parts of the robot around. While robot actuators have been around since the dawn of machines, they have some issues. For one, it is very difficult ...
