Elec: Frequency Selection Demo Using Coils, Caps & An Audio Crossover @tsbrownie

Uploaded March 2026 | Updated September 2026, 2 weeks ago

Let's look at how frequency selection with coils and capacitors works using an audio crossover. We show how inductors and capacitors actively shape signals by passing the frequencies we want while rejecting those we don’t; just like in crystal radios and speakers. We'll do a walkthrough of a passive two-way crossover, starting with the real thing, looking at the circuit diagram, then testing the crossover functioning with an oscilloscope and frequency generator. Whether you're building crystal radios, experimenting with RF circuits, designing speaker systems, or just enjoy practical electronics and DIY science, this video delivers real insight you can apply immediately.

Danger of fire and burns. Not for children. This model vibrates badly and the fuel can gets way too hot. Use proper precaution. If you dont know, learn first or do not do it. Table-top size models produce only a tiny fractions of the power provided by a similarly sized steam or gas engine. Reverend Stirling was appalled by the number of his parishioners killed or maimed by boiler explosions in the early days of steam. He set out to build an engine that would not require or produce high pressures during operation. His air engine, now known as the Stirling, was the result. Today, its efficiency (as high as 50% in some examples) and ability to use almost any heat source, including waste heat, allow it to fill niches that steam and gas engines cannot. - Marv Disclaimer: This information is presented as entertainment only on an as is basis and any use the viewer makes of it is solely up to them, and it is their responsibility to determine if the information remains current and if it is applicable to their situation.
