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 ...

OBJECTIVE: You will wind (and test) your own inductor, which you will also use in the AM radio project in a subsequent lab. You will also investigate the properties of capacitors by making a simple ...

The other day, I was casually scrolling through Google when I stumbled upon a flood of dirt-cheap RC snubber circuit modules on various online stores. That got me thinking—it’s high time we talk about ...

[Sid] makes a few PCBs a month and the hardest part of his fabrication process is always drilling the through-holes. He has a PCB hand drill that usually results in a sore index finger. After a few ...

An RC circuit in series with the coil allows full-current turn-on for reliable relay operation, then reduces the current to save power. Fellow engineer Sanjay R. Chendvankar of Mumbai, India, recently ...
