Arduino is at the heart of do-it-yourself electronics, and now the company wants to make inroads into additive manufacturing with its 3D printer: The Arduino Materia 101.
An SD card isn't just a dumb chunk of memory; it's a dumb chunk of memory with a built-in brain, a microcontroller. And at this year's Chaos Computer Congress, enterprising hackers showed off exactly what those brains can be used for: cheap hardware for makers or malware machines for malcontents.
Here at Gizmodo, a number of do-it-yourself projects are featured that incorporate microcontrollers. If you've never worked with one before, don't feel daunted, here's an overview to help you select the model that's right for you.
Researchers at the University of Michigan have created a prosthesis that makes walking much easier on amputees than current options. The trick: an artificial foot that recycles the kinetic energy generated by walking.
