Advances in methods that allow targeted remote control of neuronal activity open new possibilities for investigating and manipulating the function of neuronal circuits in vivo.

This remote controlled switch circuit can control AC loads such as lights, fans etc through the remote handset of TV. It uses the 555 timer in the bistable mode. In the bistable mode output IC555 ...

This microcontroller-based control circuit adjusts the speed of a small permanent-magnet DC motor to one of four speeds as selected by a pair of photosensors.

We frequently get home automation tips, many of which have simple circuit-based on/off control for lights. [Paulo Borges] has created something quite different, however, with his in-the-wall servo-… ...

The CBS ArcSafe RSA-12A is a custom-built remote switch actuator that remotely operates all styles of Westinghouse/Cutler-Hammer DS/DSL power circuit breakers.
