Crystal Radio--Making A Variometer (Remixed & Condensed)(4K) @tsbrownie

Uploaded May 2024 | Updated September 2026, 2 weeks ago

This is video is on how to build a variometer. For your convenience, I have remixed the original series of videos on making a variometer. I have removed dead-end ideas, things I repeated between individual videos, made corrections, etc. and put all the 9 videos in 1 shorter video.

No part of this video was made with AI.
===============================
This is the series on how it was created:

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.
