Hi Bill and ALL,
great work.

Please try to measure the current going from the battery to your circuit via a Low Pass filter
and via an analog ampmeter.

Are the 400 LEDs as bright as if you plug them into the grid ?

Regards, Stefan.

@ Stefan:

Thank you!

No, the 400 LEDs are not as bright as on the grid.  If you check out some of my other videos on youtube, I test starting at 100, 200, 300, and then 400.  This is all subjective of course by just using my eyes but, the 100 were brighter than the grid, so much so I didn't run them very long as I did not want to burn them up.  200 was about as bright as the grid.  300 a little dimmer than the grid, maybe 20% and 400 was about 40-50% of the grid brightness.  All of these videos were made with the LEDs in series but, on here many pages back, I posted photos of all of the same tests wired in parallel.  I believe the series tests were all a little brighter at each level, but it is hard to tell.

I have an analog ampmeter and I will be happy to make some tests but, I do not have or know what a Low Pass filter is.  If you, or someone tells me a value or a number for a part to get, and how to wire it into the circuit, I will happily do these tests.

Also, back many pages I posted a photo of me running 100 LEDs with only 1 wire.  Maybe I should make a video of that as well?  I will have to check but I don't think it would run 200 this way, only 100 with single wire with the blades of the male plug shorted together as suggested by I believe it was Abbarue if I am not mistaken.  Thank you.

freezer where have you been lol 

we will chat at some point im just so darn busy .....

ya know 

any how

TEST RESULTS.....


PICS AS PROOF .... you dont have to take my word for it lol ...

frist the finished unit ....  wich needs a name yet ....   


bill i award you the job.... 

lol

here is a pic

ist!

~~~~~~~~TEST RESULTS~~~~~~~~


when i first fired it up thease were my out put mesurments


i played with for a few min b4 i shot all the pics...

when i first fired it up   i mesured 85 ma ...

output

and 410 vdc ...  865 ac ....   so yes

12 aaa 1.5vdc cells im off to get the rest .....  so i would imagine it will run a little wile from all 36 .... 


i have no cap in the unit YET

ist!

[innovation_station]

 

well got all 36 batteries ... aaa's

and i fired it up and it was putting out 175ma 

do not touch it!!!   

with out any cap

ist

@all

There are now a very nice group of circuits to choose from.

@jesus,

I thought I would put together your charging jt today.

I only have some 1n4001 diodes,  1 Amp, 50PIV

I don't know anything about diodes by numbers or what the specs mean. I did look up the diode you used in my allelectronics catalog and found it under the switching diodes section where the 1n4001 is in the rectifying diode section.

I assume these are too different in function and cannot be interchanged.

Please someone, tell me if these can be used

thank you,

@Stephan,

So, using a 10 ohm resistor in series with a dmm at the positive battery terminal and applying ohm's law will not give the same result?

If it will be good enough, I will give all the results in one place for you on this.

(I think I used both my filters for use as joule thief toroids!  )

thank you,

jeanna
