The cost of 3D printing has come down dramatically to the point you can set up a small printer in your home. Those printers only spit out little plastic baubles, though. The cutting edge of 3D ...
LEDs may be garnering the most headlines these days. But high-intensity discharge (HID) lighting is as popular as ever, too, thanks to its high brightness, excellent color temperature, high ...
Light waves trapped on a metal's surface travel farther than expected. While the distance might seem quite small, it is far enough to possibly be useful in ultra-fast electronic circuits. Light waves ...
Achieving superhuman vision like the Bionic Woman's could be as easy as popping in a contact lens. Engineers have for the first time combined a flexible, biologically safe contact lens with an ...
This electronic lighting dimmer circuit is used to control the lamp for arbitrary brightness. This electronic lamp dimmer circuit work for incandescent lamp, not a fluorescent one. The dimmer circuit ...
A rose by any other name would… conduct electricity? The worlds of botany and consumer electronics don’t typically overlap. But a new device has merged electronics with biology, taking a step towards ...
This halogen light switch circuit works only for dc halogen lamps. Halogen lamps give a good light and have an excellent eficiency. In this halogen switch circuit we use a FET transistor because the ...
