This file type includes high resolution graphics and schematics when applicable. This 8051 microcontroller-based control circuit adjusts the speed of a small permanent-magnet dc motor via photosensors ...

In general terms, dimmers are devices that vary light level (intensity) of lamps by controlling the amount of power that is delivered to the lamp. Dimming can be controlled by either manual or ...

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 ...

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 ...

STMicroelectronics has introduced the L3751 synchronous buck controller for a range of applications from industrial equipment to battery-powered light electric vehicles. The 3.5 × 4.5-mm controller ...

Microchips that make use of light instead of electrons could outperform their electronic counterparts if light flow can be controlled at will. Photonic crystals are instrumental in achieving such a ...
