@all

Has anyone tried to use a DC/DC converter with their JT?  I'm assuming it wont work for many reasons but was just wondering.  I was also wondering if anyone has tried to light up an electro-luminescent strip with a JT?

@Hazens1

Any progress with those new cores, I can't wait to see what you come up with!  Keep us posted

Hi stprue,

I wanted to ask a favor of you.

I would like to see if there is any actual difference between your results using the power line pulser and a AA battery.

These are powerful inductors we are using, and it could be possible that your results are being improved by the grid's nearby presence.

It would be unpleasant at best, to think you could light a few lights only to find out that they do not work so well when the grid goes down, which it still does in some places.

thank you,

jeanna

Good call Jeanna, I will do this tonight.  I have done this with most of my other coils and the proformance usually goes up but it is better to make certain.  I will snap a few more close-up shots as well!

...

The Relay coil could also be the JT transformer itself and this circuit was advertised as a recovery method for CEMF.

My question is:
Is there any limit to the number of these that can be added to the JT/relay coil?  Does Lenz' Law come into play with this tactic?

just to make sure we are talking about the same thing.

Lenz's law deal with induction.
Lenz's law states that the magnetic field of any induced current opposes the change that induces it.

cemf = "counter-electromotive force", whitch is the electromotive force, that pushes against the current which induces it.
it is something caused by the current passing through a wire loops and the loop's proximities.

sorry, i don't see how diode(s) and cap(s) can help against this.
the only way i know around it is coil's configuration.

WAY DA GO FREE!!!

It looks like you managed to get one good camera. pic4 looks like the AA to me?

I am glad you could do it in record time too1

How interesting they have one with 2 caps.
Interesting how different the voltages are too.

very nice,

edit,
I see we posted at the same time.
AAA for everyone? OK go 4 it!
