More of my EV kick coming through. A solar tracker is used rotate a solar panel to get optimum energy from the sun. This one uses LEDs as the light sensor and mosfets to drive the output to rotate … ...

Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

This simple LED current sensor measures a low voltage drop across a sensing (shunt) resistor. When the voltage exceeds about 10mV, the LED comes on. Two circuits are provided: One for sensing current ...

In production, this may be replaced with a zero Ohm resistor. The open circuit protection circuit shown utilizes R9, causing it to serve an additional function, in conjunction with Zener diode D2. In ...

Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation that draws upon the familiar etching pattern inside most ...

In a direct attack on both the laser rangefinder market and the ultrasonic rangefinder market, LightWare Optoelectronics (Pty) Ltd, a South African based manufacturer of laser rangefinders, has begun ...
