Have a look at the picture there is a little circle and a photo resistor ? (light sensor)

look like you are right.

i took that circle for a screw emplacement as i don't have a photo cell in my units.
i just wonder why put a photo cell when the solar cell could be use.

@ TheNOP

Thanks for the input on your edit but I would like to point out that I'm only here part time with only certain input capabilites, figuring out electronic circuits using ZPE or other methods and explaining them using complex mathematics isn't my cup of tea....


The rest of the people on this that that are good in electronics need to see your response and see for themselves if the solar panel to battery circuit can be used properly with the JT circuit without blowing the existing charging circuit.

Getting more from the sun than we are getting now will be a bonus.

i am not into ZPE myself, i don't even have the smalless idea of what that is.
i am all about using known science faqs to do more, with same, or less.
complex mathematics are not what i like best.
but i prefer them to obscure babling about something no one have figured out yet.

@ all

Ok so it looks like the solar panels work with the sun but not so good with CFL or incandescent lights indoors....maybe no gain to be had there.

The Fuji JT on the other hand still could light up a lot more LED's as far as the bang for the buck, if we were to nail that circuit down to a version that can fit in that UFO looking prototype I posted earlier we can put a prototype together

ok guys with the solar pannels im useing the led shuts off because it sences light and charges the battery......

when i place this solar pannel close to the cfl ... it likes it ....  makes the pannel read .7v wich is enough to trigger it to charg the battery and this is at night as it burns ...the bulb....  what will happin in my light stick is this the top pannel on the verry top will control the light turn it on and off in the right time   the 3 or 4 i will mount below the cfl will strictly be recharge day and night.... they will also feed the cam unit ... wile they charge... i will disconnect all outputs for the leds they are not needed and they do not DISAPATE ENOUGH POWER TO POWER THE CAM UNIT ...

so ...  it will require a dirrect connection to the battery ... but we will use the place where the led was on the top l to power a transistor ... to turn on the battery with the photo cell ..

if this makes sence to you all...

ist!

@ist

I posted a work around that at the end of last page. I think easy enough.

Just trick the circuit into thinking it always daytime. And put a switch on the light.

Edit : sorry i forgot great work , but then i would be righting it all day long .

Thank again!

IST, you are a great craftman.
cool stuff you got there.
