Kapanadze and other FE discussion

Oh this looks so cool! Single transistor oscillator for my own setup!

If I want to use this for an oscillator, should I use a MOSFET or a transistor? If I charge a cap from 9V battery, how can I use the HAL sensor to switch a transistor or fet?

There is different types of HS in the market.
The best sulution is this.
If you have some different HS in your "box", than take a Datasheet and there will be explanation.
In most of Datasheets, there is schematic of connection with some types of transistors or
You can search Google for pictures with your type of HS.

It is just a single transistor oscillator, whose feedback is made using a hall effect sensor.
No "magic" results. The LED lighting does not indicate that it would receive more than the 1.2W used as an input. This is another useless video by a dreamer who wants to keep his illusions, and consequently does not make serious measurements of input and output powers. In the comments on youtube, he therefore receives congratulations from Georges Chaniotakis, notorious fake video maker.

Plus, he hides half of the circuit and then asks for a donation!

did you notice 2 different waveforms  one a squar and 12v at 100ma using ferrox and the other a negative going pulse
and 190ma  using iron garden wire. Amazing  don't people like to spin a web

In fact we can make JT with  similar Coil like Franch man.
Test without Magnets and with.
Here is small notefication.
The best transformer is with very small gap between wire and core.
If we make setup which resonate inside, than we create gap, which is bad, frow Induction point, but maybe 2 times longer core with fixed and fully filled core with magnet on the end can give Amplification?
P.S. For realisation of JT circuit with ordinary transistor we need second winding with small diameter wire winded with fat wire or use system like this:

Every kind of circuits will give different results of course, because of different transistor opening moments.
HS is good for very sharp and low output Impedance if we compare with JT.


But!!! If there is possibility that Magnet can make Amplification, it will be usefull.
