@All,

I wanted to test the claim from Gadgetmall that a Joule Thief charging a Boost capacitor
(650 Farad 2,7 volt) was a over unity process. Gadgetmall claimed that one could recharge
the input battery (one NiMeh AA battery 2500mAh) from the Boost capacitor every time the AA
battery needed charge. I then did build a circuit that automated the process of recharge
the AA when the battery needed charge. The newest revision of this circuit (with software) is
attached. This circuit connects as shown in the attached drawing. This new circuit uses
only 0,6mAh from the input battery. The circuit will monitor the AA voltage and the BCAP
voltage. If the BCAP voltage is charged too much then the circuit will dump some BCAP
charge to a load to keep the BCAP voltage at a safe level. If the AA battery voltage drops
to a preset level (adjusted with a variable resistor) then some charge from the BCAP is
dumped into the AA battery to keep the battery charged. The attached circuit is doing
this without any operator input. I have run numerous tests on the system and I have not
found any evidence yet that this circuit is over unity. It may be the extra 0,6mAh circuit draw
that "destroys" the over unity process. Gadgetmall uses a manual method of charging
the AA from the BCAP battery and claims that this method is over unity. It may be so.

Thanks much for the help Pirate and Groundloop.  I did just find the JT threads and spent the last 15 hours reading them so I'm beginning to get a handle on all this.  whew!

Wow...I want to thank you for your apparent honesty...
and your really professional circuit construction techniques...
I think your circuit is going to become of use to the greater
overunity energy community as a whole, and I will always
give you credit and reference your circuit if/when I use
parts of it in the future...Thank you again, very much.

BTW By the way, I feel that 0.6ma at 5VDC = 3.0milliWatt
up sleep current should be sufficiently low as to not
destroy overunity while using with a 1Watt net user load
resistance with reasonable duty cycle.

Sorry to post here but I am really trying to get up to speed on the JT and would like to try the circuit gadgetmall has posted.  However I cannot find any page "997 to page 1003" on a Joule Thief thread as the seem to end at page 858.  Also I sent email to gadgetmall on his web site but no response yet.  Can anyone tell me what a 102 capacitor is - that is what is the value in farads and working voltage?  I purchased a 650 Farad Maxell cap and am trying to round up the rest of the parts.  I also don't know which is the 'advanced Joule thief message thread' - does anyone have a link?  I have an idea on the JT that I think may be valuable if I can just get up to speed on it.  I think it may be part of why gadgetmalls first one worked and subsequent ones were not as efficient but I need to get one put together first myself.  Please help.  TIA

@e2matrix

The Jt circuit is shown eight posts up from this one.
and he meant "2nd stage Joule Thief" under "Forum"
heading. The 102 cap means .1uf cap at 25Vdc - this
is standard notation for a 5Vdc<->12Vdc mylar
digital circuit bypass capacitor...Note: Your post is an
OTP off-topic-post here...please direct future inquires
to "2nd Stage Joule Thief" thread. Thanks.

@mscoffman,

Just to clarify, the circuit uses 0,6mA hour from the 1,3 volt INPUT battery.
So this gives approx. 0,78 milliWatt hour of usage from the AA battery.

A ceramic capacitor with a marking 102 is: 0.001uf  = 1nF = 1000pf

Thanks,
Groundloop.
