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

Published 2024-04-30

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.

Carbon brushed can be obtained at your local auto parts store. They generally have a nice selection of alternator rotor brushes. Just pick out the ones you like. Generally, rotor brushed are fairly small. Better yet, they are easily carved into shape. AD0TJ

Thank you as always for the great content

It looks very aesthetic. It will probably work fine. However, it is time-consuming and difficult to perform

Interesting, i have a 1920s Kellogg wavemaster radio that tunes with those

As its 3D printed, a screw type ridge could be incorporated so as to make winding easier? Also, since its is 3D printed, holes could be made, which I not sure of, decrease capacitance?

Nickel has a relative premeability of 100 of 300 pre the great wikipedia. I would think that would cause some problem, but not sure how. Any one?
