If you are an RC modeller, then this circuit is for you! The compact RC Switch let you turn something on and off from a regular R/C channel. The device is powered entirely by the receiver, drawing ...

Here are some DIY LDR switch circuits available on our website and the web. LDR switches are used to switch a relay or other device when light are present or absent. LDRs or Light Dependent Resistors ...

In the 120V circuits of homes and offices, the grounded conductor is the same as the neutral. Typically, when wiring a switch for a 120V load (e.g., a light) only one wire comes to the switch and only ...

Experimenting with batteries, bulbs, buzzers, switches and other electrical components is a great way to learn about circuits and start to think about how to incorporate sounds into your Build a ...

All sorts of things can happen to cause power outages – trees can contact aerial utility lines, vehicles sometimes strike poles, birds and squirrels can make the wrong move and trip electrical ...

If you’re thinking of connecting an electrical generator to your household to provide backup power during an outage, there are different options. One of the simplest, most flexible and most economical ...

The requirements of Art. 404 apply to all types of switches including snap (toggle) switches, dimmer switches, fan switches, knife switches, circuit breakers, occupancy sensors, and automatic switches ...

Integrated circuit technologies are enabling intelligent, chip-based, optical packet switch matrices. Rapid real-time re-configurability at the photonic layer using integrated circuit technologies is ...

Electronics keep shrinking, but silicon is starting to run into physical limits. To go smaller, researchers are turning to ...

When we moved into our new home — a major fixer-upper — I thought it wasn’t cozy because of the arctic-blue painted walls (everywhere) and swirly brown 1970s carpets. And sure, the décor wasn’t ...
