This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

I recently helped a friend install a “smart” Ecobee 3 thermostat in the second floor of his home, see “HVAC Upgrade Shows Interconnect Complexity of These “Simple” Systems”. He was so pleased with its ...

We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

Digi-Key, the electronic component distributor, has decided to venture into schematic tools with Scheme-it, a free web-based schematic drawing and diagramming tool. Designed using HTML5 technology, ...

Every now and then a remote control acts up. Maybe you are trying to change the channel on your television and it’s just not working. A quick way to determine if the remote control is still working is ...

These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials. They're a great way to learn about ...

voltage. Often a passive single-pole RC filter will satisfy design requirements, but this approach typically suffers from several drawbacks including slow response time, noisy results, and having an ...
