... capacitors are beginning to catch up in the
race on my choice list for components - using
them in place of batteries.  I'm now faced with
the question of what designation to look for
equivalent to the storage of a 12V ~

@geotron

In the schematic you refer to and it includes the 1N914, the point is:
WHERE the 1N914 diodes are connected and WHERE the 30A diodes are connected.

The 1N914s are in parallel with the audio transformers' secondary (8 Ohm) coils,  ok?  Here there are surely currents that they can handle safely.

No the are to week,

You will give attention that an 2n3055 must be drive on base wit up to 2 Amps base currents (or peaks)
the MJ802 up to 3 times more .
so the transformer will also produce BACK-Currents&Voltages.
(like back-emf, if transformer switch the signal OFF)
The Diodes have to stop the negatibe impulses to the basis of
transistos. This is the idea to use this.

Perhaps my capacitor idea wasn't so good - there's
probably a lot of modifications that would have to
be made to get it to perform right...  ??

Below I have outlined what I'm imagining is the
correct way to go about connecting the L.Pollaehn
timer circuit. The item labedled 'RELAY' has me
a tad confused, as it doesn't seem to be connected
to any other part of the circuit. Also I'm not sure
where this timer gets its power supply connected.

pese - I have circled a set of three diodes. Are these
the ones you are referring to as being set backwards?
The diagram appears to be a loop, and those ones are
pointing the opposite direction I would think they
ought to be.

I have an ask:
Why the 2 electrolydics habe both polarity wit negative side to bridge ?
Why not positive side ?
Is both "wrong".
Why not also with ONE Condensor can work ?
(the load ist only conect to bridge , so it must not
capacity separateting the "bridge".

Why dist its used the electrolydtics ?

EVEN without, this will work !!
Without the problem, that you have with
Polarity Problems.

-----------------------

Also -- it give more problems, that you can find yourself in THIS circuit ...

It looks to me like the positive end will capacitate
through to the negative side, supplying the positive
terminal on the end with flow... they must serve
some purpose I'm unaware of - it might be that without
them, the positive flow it too great and the batteries
drain out before they charge up?

OK - The relay is what leads in... on my previous diagram-post
in the circuit by L.Pollaehn? Then the +12V goes to power the
timer circuitry?

I may be understanding this a little better now if my
guess is correct -

Hi Geotron,
I would connect the top end of the relay pole through a 1K resistor to the 12 volt line, also connect the same pole to "timer input" next connect the centre pole to common ground. The relay then provides pulses to the timer input between 12 volts + via 1K resistor and ground.

Loner - when you refer to the cap in the timer section
of the switch, do you mean the one labeled 3.3MF? If so,
by decreasing the size of this cap, you're saying it
would have the effect of.... increasing the rate of on/off
signals?  What is the purpose of having the timer chip
and everything when the capacitor is what controls the
signals? I'm probably jumping to conclusions on this one,
and if so I apologize.

Well, here it is - a modified diagram with the 1K resistor
and everything connected the way I'm picturing it ought to
be... looks good?

I'm not really certain what purpose the
1K resistor serves... is it to direct the flow
of electricity? The way I have illustrated it, it
looks like the +12V will go straight through into
the Timer Input on the Switches, bypassing the relay -

The diode configuration looks to provide a push pull type of arrangement, when the relay is closed one set of transformers is conducting more than the other set, and when the relay is turned off the BEMF affects the others that were not conducting. The 1k resistor is for current limiting since the relay is effectively shorting the power buss to produce the pulses. This is the timer circuit BTW, as shown.

not working !
you cant drive the transistors with about 1omA current  (1k resistor)
even you cant charge the elctrolydt condensor up ti unload this to drive the transistors no such way . even the transformers 8:1000 Ohm can never work. the whole device. is only "exerimental"..

Fin to learn somes from electronic , thats all

No, it is only "half good".   crowclaw meant the lower relay contact goes directly down to the negative battery polarity, ok?
The 1 kOhm and its connection is ok to the upper relay contact. The 12V goes directly to the timer input of the Tesla switch via the 1 kOhm and whenever the relay is fired, the timer input is connected to the negative polarty instead of the +12V. In your drawing the wire from the lower relay contact now goes to the 1000uF capacitor,  this is wrong, that wire should go to the GND instead of the cap.
This is what crowclaw suggested.

Hi Guy's

Has any body tried Ron Cole's circuit out for themselves yet or have any thoughts?
http://www.freeenergynews.com/Directory/Electromagnetic/TeslaSwitch/Tesla_Battery_Switch_PGFED.pdf
see page 12.

Just in the process of experimenting with it myself. I have three 18000uf 30v capacitors, a hefty bridge rectifier and a 55W 12 volt auto bulb. The battery is 1.7AH 12v gel cell. I am pulsing a relay from a sig gen with a variable output from 0.5Hz upwards with min 15%>85% mark space ratio.
Pulses on battery approx 15volts+ but tend to be a little unpredictable!!

Hi crowclaw,

Though I have been aware of the collection on Ron Cole's circuits, now that you mentioned it I recall an US patent (already referred to in this forum) which includes only 1 battery and two (super)capacitors and two or three DPDT switches and it claims the circuit more than doubles the run time for a load driven from the battery and the switched capacitors vs the battery alone.  See here:

http://www.google.com/patents/about?id=85R6AAAAEBAJ&dq=7085123 

and they have a patent application on a variant circuit too :

http://www.google.com/patents/about?id=wiWqAAAAEBAJ&dq=7085123

Unfortunately their circuit needs unipolar supercapacitors, not readily available?

rgds,  Gyula

NO PROBLEM.

I seen an lot of Application (Speaker-Systems) , in that was used (for Audio AC) 2 polarized Electrolydtics. , in serie with both neg connected . and 2 positiv leads as unpol.  lead connection.
(also all-in-one- unpolarized- Electrolydtics . from OEM are produced this way in ONE Tube ! 
(If you are "angry" , than you can shield each cap
with an additionally parallel diode.
