LED strips still use power when seemingly switched off. In case you want to prevent that, you have several ways of totally switching off power (including manually switching off the power), one of ...

Do you have an old PC lying around the house which absolutely no one wants? Then you can convert it into a dedicated controller. Communicate with the real world via the parallel printer port on your ...

Vishay Solid State Relay (SSR) outputs can be wired in parallel enabling the user to benefit from lower ONresistance and higher load current for ac/dc switching applications. This technique is also ...

This project, Smart LED and Relay Control with Hand Gestures and MIT App using ESP32, allows users to control RGB LEDs and a relay using hand gestures and a web interface. The system uses the ESP32 ...

Abstract: This paper studies secure transmission with parallel relays. We use relays to help users for transmission, but we also wish to keep the information secret against the relays. We first study ...

Light-emitting diodes (LEDs) are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the ...

It was imperative that no wires were cut, relays added and that the lights were in the OEM housing. BHPian ShivC recently shared this with other enthusiasts. Got all the external lights changed to LED ...

Abstract: The author considers the following arrangements desirable: For radial feeders not in parallel — inverse-time-limit overload relays, with selective ground relays. Radial feeders in parallel — ...
