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

Here is a simple Arduino Camping Light project. In this design, only one push button switch is used to control the light output (from a bunch of white LEDs) between off, dim, medium, and full ...

Take a gander at the Giant LED bar graph which [Chunky Hampton] recently completed (from this image we don’t think the nick name suits him). It’s simple both mechanically and electrically, but we love ...

On a physical level, a transistor’s internal functioning is very complex, but, in practice, using it in some simple experiments is quite easy and affordable for everyone. A transistor allows to create ...

You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed ...
