Selfrunning cold electricity circuit from Dr.Stiffler

[Loki67671]

@All,
Todays experiment results:

Circuit is SEC exciter in the currently stated configuration
Power input = 20.12VDC base coil tuned to draw 43ma from supply
22uH choke terminated in an empty connector row 90 degrees directly away from the Osc and power rails, 2+ inches
Within 10 seconds the choke was getting very warm....at between 11 to 13 seconds I opened the positive rail
Not doing so would have caused the inductor to open.
I will have to test this component now to see if its value is still the same, after the heat 

Secondary test test,  same configuration as above, new choke
voltage measurements attempted across choke with fluke 179 DMM
measurements taken +on collector side -on pad termination side
results:

13 VDC Input         current=29ma   current drops to 23ma with meter loading      observed quick positive voltage drop decay to zero 
15 VDC Input         current=32ma   current drops to 26ma with meter loading      .002 VDC drop measured on choke
17 VDC Input         current=36ma   current drops to 34ma with meter loading      -.004 VDC drop measured on choke
20 VDC Input         current=45ma   current drops to 44ma with meter loading      -.011 VDC drop measured on choke

Voltage went negative in relation to initial condition indicating current reversal and flow into choke from the parasitic.

I burned my finger.........again!

Best regards

@Loki
Were you  using an RF probe on the meter? The values you show look right but my RF probe across the choke shows 185Vpp.

So you don't think you have a lock on burned fingers I thought I would show you my finger 

@Dr. Stiffler
No...I can't find it I'm ashamed to say So I knew my readings could be off, ahem, would be off. I was most interested in the polarity and the trending of the circuit's reaction to the meter insertion at specific supply voltages. The power was removed between every measurement and this sequence was repeated three times. The results are repeatable but that could mean I screwed it up the same every time, no? I must admit that you are the man for the burns, I'm not worthy.  I'm going try and borrow one from one of the RF guru's tomorrow. I tried to post my backing plate work this morning but the blasted forum went south on me twice and I had to leave. I have to work on the photo sizes too. 

Best regards,

Jim

@Loki
Yeah the forum seems to get pretty sick every now and then. I had similar trouble.

Hey, 0.01uF and a diode works fine in a pinch, the diode goes across the pos lead to the gnd and probe with the cap. Don't even have to enclose it, wrap it around the meter tip.

@Dr. Stiffler,
I forgot all about that. Thanks. 0.01uF and a switcher like were using or an RF pin diode? Very cool. Excellent tip!

Best regards,

You don't think they may have seen my work in 2005 on electrodes; www.stifflerscientific.com/electrodes.asp where I used an SS strainer as shown in the following picture.

Haha, brilliant. I guess I did not look at that page on your website, else I would've known...

So is there merit in using the SS strainers in your or their configuration?

Doctor,

I repeated the fast experiment and my finger is burned. Even without the short wire it gets very hot and very fast. About 20v and oscilates between 28ma and 42ma as I touch the choke with my hand. I can not leave it unatended otherwise it will definetly burn up.

Connecting to an AV Plug with LEDS will cool it off somehow.

Fausto.
