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

jadaro:

Thank you for your suggestions on diagnosing my coil problems.  I think it is as you said too low base resistance.  I just found that all 3 of my vr are burned.  These were new and 2 of them are heavy duty rheostats (wire wound) but now when I test them, they are all over the place, mostly show continuity with no resistance.

This would explain me frying the transistors and them getting hot.  I need to find better vrs somewhere.  I didn't think there was too much juice flowing through the base resistors and they should have been ok but...anyway, thanks for the help.

Xee & all,

   Per our recent PMs, I'm wondering if there might be some way to match or exceed Jeanna's "1kv with a AA battery" using the Chilliqueen.  What's my point?  Well, it's current draw: The chilliqueen draws much less current; and also thinking that something much lighter than toroid would further improve draw? 

  With a single AA, the 4kv trigger coil is putting out around 22v rectified and the camera coil around 250v rectified

I've been looking around for different possibilities, and wondering if anyone here might be able to recommend something that works.  Paralleling coils?  Voltage doublers? Two stage step-ups (transformers) like the stun gun circuit?   

  I've been using your secondaries/trigger coil schematics from this thread. I also tried the attached voltage doubler circuit, but could not get it to work.  Anything?  Anyone? 

Thanks in Advance,
Mikey

Just so you know, Jeanna can get over 2kv with her large wound toroid.  This is without a trigger coil.  I have not been able to do this yet I am afraid.

@ sirmikey1

This is a circuit I posted early in this thread. I believe it is putting out over 1000 volts but I have not measured it. It should work with other transistors also, but these are the only transistors I have tested it with. I have tried to use trigger coils in place of the ignition coil, but I have not found any that will work. I have used a small toroid to replace the ignition coil and that worked but I do not know how much voltage it was generating.

Why don't you use Jonnydavro's  simple sec circuit? That puts out over 1000 volts and only needs one transistor.

What camera coil are you using? If you use that in this circuit you may get over 1000 volts (if not try reducing the 1M resistor to a lower value). The extra transistor increases the current which in turn will increase the voltage generated by the coil.

Hi Mikey,
Here is something I want to point out.
I am no longer satisfied that the amperage readings are accurate.
It is for this reason I have stopped mentioning them. Also I did that test with the transistor with various loads on the secondary and they all took the same amount of time to drain the battery.

I could be telling you that my amps draw is 20mA because it can look like that, depending on what resistor I use at the pos battery lead.
If I use a 10 ohm resistor the amps draw looks like 50 mA  but with 33 ohms it looks like 20mA, and it makes sense, but when I use a 1/2 ohm resistor it appears to be 120mA .
But I do not use any resistor when it is in use, so what is it? 60mA ?? See what I mean?

I do not know how a 2 transistor circuit can use less than what it takes to turn on 2 transistors. I suppose they can be on for miniscule amounts of time, but chilliqueen told me the NPN gets really hot in a few seconds, but he can sink the heat.
grr.
It means something needs to be worked out still.

The part I am looking at these days in respect to draw, is what is wasted?

I am learning that if I make 2000 volts and only need 800, I am still making 2000v and there is nothing using them but they are disappearing.
It is like so much we do, we waste and don't even know it.

That is the reason I love lidmotor's rheostat at the pos wire from the battery. It lowers the volts, and it lowers the amps at the same time. The drain time is very much extended, and that means it is not being wasted.
Obviously if the rheostat lowers the light then it is removing what you want, but many times I can turn that rheostat, and the light will stay fully bright for a part of the turn.
The extra wasted is between that and the fully opened state.

This is really tricky stuff. We have no real direct way of knowing what we are using and wasting, but I am sure as I can be that we are wasting a lot.

thank you,

jeanna
