Second Stage Joule Thief Circuits

IST,

The video is nice but I'm afraid it is not showing harmonics. Harmonics would be shown as 2 separate waveforms horizontally across the CRT. If there were 3 harmonic frequencies, there would be 3 waveforms. If the waveforms were in sync, you would see an increase in amplitude of the waveform where they lined up.

Sorry.

it looks like to me harmonics ...

i have seen MUCH OF THEASE

that video is not the best demo of it as it is not core tuned hardly at all

the point was to show how to use the colpase and devide it into a few feeds and amp it with a magnet .. i have done so as i add the magnet in the videos that follow you at the end see resonant magnet interaction and harmonic bands ... THE SAME HARMONIC BANDS SHOWEN ON MY FIRST VIDEO...

: )

ist!

Hi guys what happened to the heater circuit it was really interesting. If one ecomplish this I think it's much better than light.
Gadgetmall you managed to charge that Ucap fast?
Thanks

It may look like harmonics to you but it is not. It is a single waveform. And yes, I am sure you have seen many of them. That is one of the advantages of a scope. You see the waveform not just the voltage or frequency. Scopes are used extensively in the service field. It is really hard to see what is going on without one.

Also if you look carefully at your scope when you add the magnet, you would notice that you are only offsetting or shifting the waveform. Not amplifying it. It shifts vertically.

I really think you need to read up a bit on scopes and waveforms. I'm not trying to be rude but, to people who know how to use a scope you do not look very good, and you are misleading the people who don't.

it is  related ...  those bands ... are CLEARLY BANDS....  OF SOMETHING ... WHAT ARE THEY ?

AS I TUNE OUT MY KICKS  to a large view those BANDS SPRED OUT ...

we will see ... 

i beleave them to be the same BANDS I TUNE IN TO WITH THE USE OF THE MAGNET 

i can be wrong ... im just 1 person with AN ANOLOG SCOPE and i dont see anyone  showing scope shots that prove this diffrently ..

none the less that little cridder works well so far ..
