KITTY LITTER AND BROKEN LIGHT BULBS POWER THIS HOMEBREW GAS CHROMATOGRAPH

KITTY LITTER AND BROKEN LIGHT BULBS POWER THIS HOMEBREW GAS CHROMATOGRAPH

We’re always on the lookout for unexpected budget builds here at Hackaday, and stumbling across a low-cost, DIY version of an instrument that sells for tens of thousands of dollars is always a treat. And so when we saw a tip for a homebrew gas chromatograph in the tips line this morning, we jumped on it. (Video […]

Chemical Wireless Communication Without Electronics

Chemical Wireless Communication Without Electronics

Researchers at Stanford University have just invented a revolutionary way of communication. They are replacing the conventional way of wiring, wireless, radio and Bluetooth connectivity using chemicals that can be found in every house. Nariman Farsad, now a postdoctoral fellow at Stanford, had built the first ever experimental chemical texting system in York University, which

One step closer to the ‘ultimate battery’

One step closer to the ‘ultimate battery’

Although scientists are still working toward replacing lithium-ion (Li-ion) batteries with lithium-air (Li-air), or lithium-oxygen, batteries, researchers at the University of Cambridge have developed a lab-based demonstrator of such a battery. It is safe to say we still have another decade before we can begin to utilize such powerful batteries as scientists work to make
