8 legged spider robot

“This robot uses only 4 linear micro servos, an arduino nano, a bluetooth transeiver two lipo battery’s in order for it to work. The goal of this robot was to keep it as simple as possible but remain the most important movements. This robot uses 4 micro servo’s salvaged from old and broken indoor rc-planes and helicopters. these …

Antifreeze to improve aeroplanes, ice cream and organ transplants

“Design of aeroplane wings and storing organs for transplant both set to be safer and more effective, thanks to synthetic antifreeze developed by University of Warwick. Inspired by natural antifreeze proteins, researchers create iron-based synthetic imitation which has been shown to slow growth of ice crystals. Could protect aeroplane wings and wind turbines from ice damage, make ice cream smoother …

Harvard researchers develop tough, self-healing rubber

“Imagine a tire that could heal after being punctured or a rubber band that never snapped. Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new type of rubber that is as tough as natural rubber but can also self-heal. The research is published in Advanced Materials. Self-healing materials aren’t new …

Interactive NASA Shirt Using Crazy Circuits

“We love doing electronics projects. We love teaching kids and adults how to build awesome electronics projects. For years now we’ve found that there are really only two ways doing DIY electronics: Buy a very expensive kit; Use inexpensive off the shelf parts that are hard to use. There didn’t appear to be any middle ground between “easy …
