Okay those are Maxwell Boostcap, 2.7V, 650F.

Yes Boostcaps have a liquid electrolyte in them verse super caps do not or not the same electrolyte. some how they have special properties that absorb spikes of electrons and store them as Amps and volts . I believe supercaps of a higher value will work with modification from the original Jt . here is the cheapest dealer of maxcaps dealers http://www.tecategroup.com/store/index.php?main_page=product_info&cPath=18_20_39&products_id=162&zenid=68cc04483e2f933e5afcec3115c3ac15   
78 dollars plus shipping   UPS in the us plus haZmat fees about 110 to deliver in US ..
i have them for 55+ship no hazmat fee but i only have a few left less than 27 650f

Hi Gadgetmall I had build this but with some modifications in number of windings to charge batteries.
Instead of that diode I used four diodes as BR. The voltage continued to rise on the DC side and then I switched it off cause the cap I'm using is 2200uf 16v and it was getting higher in voltage and a skriching sound was heard.
What if I use a bigger cap could I light more leds and charge more batteries?
Thanks guys.

@ paul

a super cap on the input of what your trying to build with batteries will work fine .. you need a core that rings at the battery resonance .. the output  ringggs the battery  but i have found cirtan batteries to charge darn fast .. when in tune ... the super cap gets flicked from a aa it runs then at a steady freq ... for some time when it cuts out ... it is triggered to be flicked agin ...  this entire time your core is rinnnnnggggg the battery ...

is

all in all batterys suck ... caps are much better

ok think about this ...   tesla ... and its always back to the bible on this one ....  said translating devices  this means caps or batteries ....  with radient! unrectified in true material resonance .

dont get hurt!
