You know the type — couple of aluminum extrusions, Class 4 diode flopping around in the ... But truth be told, I’m not convinced the little fan has enough power to push the exhaust out of ...

Three laser experiments today: laser-induced electroless copper plating, laser-assisted electroplating on stainless steel, ...

A diode allows current to travel in only one direction. With that in mind, [Alex] built a mechanical diode that will only allow gear rotation in one direction to be transmitted through the system.

Researchers at Nichia Corporation have demonstrated green InGaN-based lasers grown on c-plane sapphire, with lifetimes capable of supporting commercial applications. The demonstration of green ...
