Selfrunning cold electricity circuit from Dr.Stiffler

I wonder if the LEDs can be replaced with an equivalent resistor.

assuming 150 Volts across the 10 uF cap.  Then we calculate R :

     R = 150 volts / 8.6 mA = 17.4 K ohm

If this gives the same results, supper, if not, it might be some LED dynamics that we might not fully understand.

Can you draw a detailed schematic of your circuit?   Is it the basic Thomas oscillator you had on your web page?

LEDS, sometime in the hopefully near future with equipment better than mine for thermal measurement will confirm or deny my meager observation. But if you look at www.drstiffler.com/buildup.asp at the bottom of the page, you may see what I am talking about and I will not bother to go further than to state that the LEDS appear to be "Thermal Neutral".

A resistor can be connected across the circuit in place of the LEDS and the measurements are very favorable and equivalent heat is evident. There is another approach that I worked on before leaving for the holidays, yet there is an issue of will the person making the suggestion accept the credit, as I can not and can not discuss it until this is resolved. But a better method than the resistor does exist where the out come is significant.

The osc. is the 'Thomas' osc and it uses a PN200 transistor. There is a startup resistor of 220K from the collector to the base. The collector end of the standard coil arrangement is coupled to the base through a 56pF Silver Mica. Thats it except for the standard power rail decoupling.

CAUTION! Every one should use care with these circuits, they can bite and STILL will for no reason burn out significant numbers of LEDS. When using filter caps across the Plug, never remove or add or break the series chain until you have carefully removed the capacitor and discharged it. Other wise bye, bye LEDS.

ATTENTION ALL!

These circuits have been on circuit boards for some 5 days now, in various configurations and work BETTER than on the proto-board with all its stray capacity.

@DrStiffler,

Please can you describe what you are showing in the first picture in your document.
I guess this is the philosophy behind your thinking.

What?

What document and what picture does your question make reference to?

Sorry but What? Would that not be nice to put a philosophy in a picture.
