New Jewel Thief "Resonate LCR Circuit" Much less energy draw....

[jadaro2600]

can someone put a scope on this thing?  I appear to be getting decent AC off a secondary...

Or I should say that I'm getting the same voltage rectified off both (either) side of a secondary.  As if the in-pulse is just as effective as the out-pulse.

You can use a neon bulb. If both electrodes light it is AC. This circuit has current pulses that go up fast and then come down fast later. The output polarity depends on if the pulse is going up or down fast. A regular JT goes up slow and down fast.

I'm not quite getting enough volts to light a common neon.  This is interesting though.

I'll dig around for a smaller one, EG sent me some in a surprise box.

I'm just not getting enough voltage; don't have a spare core sitting around to wind a decent transformer, and toroids, despite their benefits, are a pain in the ass to wind... especially when I need a 100 or 200 to one ratio.  I would like a 400:1 ratio, but I think it's asking a bit much, the voltage across the terminals might jump from there...and there may be a breakdown.

I've though about using an electric guitar pickup for a coil, they're wound numerous times and have a magnetic core.

@ jeanna

This will run on less than 1 volt and I am sure your EB will supply enough current to run it. You may want to change 2M resistor to lower value to increase brightness of LEDs.

Thanks xee,
I will keep this for the weather change.

Meantime I will also order some magnesium ribbon.
If I can improve my results by a fraction of what lasersaber has, I could lite the park... not that I want to, but I will love to bring it inside from the EER.

thank you,

jeanna
