Power ratio over one

[gyulasun]

Hi David,

Thanks for the infos.  So your assembled circuit as per my drawing works from the normal 120V mains? this is you have not mentioned.
The resistance (as you name it)  which is the loading effect of the primary coil of the transformer you connect to the green output coil comes from the fact that your output AC frequency 2-8 Hz and this is considerably lower than the mains 60 Hz frequency the transformers designed for. Hence the inductive reactance of the primary coil is much less (if I consider a 5 Hz AC output  from your green coil, the ratio is 60/5=12 so at this 5 Hz frequency the transformer coil represent a heavier load to your device:  say if it has 6000 Ohm inductive reactance at 60 Hz, it will have only 6000/12=500 Ohm at your 5Hz. 
One remedy would be to use at least two identical transformers, considering you happen to have some...
I show you a modified circuit,  where you can see both the primaries and the secondary coils are connected in series.  This way the primary inductive reactances are doubled, this involves your total peak output from the green coil gets divided by two (from one transformer primary coil point of view),  hence their secondary outputs are also halved  so this is why they are in series to regain the half-half divison at their primary.  Notice: you have to figure out the correct sense of connecting the secondaries in series: in the wrong direction you will not have any output, if so you change one secondary wire pair for the opposite sense.  You can check this in advance by using the mains but be very careful!
This may sound complicated or unusual for you but the good solution would be to design a dedicated transformer for your low frequency output range...  just like an audio transformer is designed from 10-15 Hz up to over 10 kHz range.

One more thing: when you connect a transformer to your green coil output and load the transformer's secondary with a lamp,  this is NOT the situation like your driver coil load will represent.  Because your driver coil is seen by your battery as a pulsed load, not a continuous one.  (A light bulb or a resistor is a continuous load, they are on in every fraction of a second,  while your micro-switches just break this continuos loading effect just by your repetition frequency.)  In other words, they make the loading effect easier for your generator coil.

I will let you know about this one tomorrow,

Thanks!

Just to let you know that I did some small tests with a neomag and a good sized reed switches (picked up a few during the weekend) and my conclusion is that there is very good directionality in positioning the magnets, so I will be doing some others tests with a standard DC motor with neos mounted on the shaft and four reed switches. I am curious to see if it will work and also what type of power it will draw. Then by using some caps, I can maybe catch the flyback and reuse it.

Regarding the circuit with one or two tranformers by gyulasun, I do not think it will work given the very low power production. When I have some time, I will make a diagram so you can test a free-runner without transformers, etc. It would be very simple in fact since the drive side needs to switch polarities, the gen side is also producing switched polarities, so by simply connecting the output of one gen to where the battery is, and instead of reversing two of the wires to the micro contacts, keep them connected all the same way since the generator will do the switching each time it changes direction, this should start by hand. Anyways, I'll make a quick diagram but it would be very interesting to see if it would work without a battery.

The transformer ideas are not the way to go. The device runs at 2-10 Hz and the transformers are built for 50/60 Hz. I have considered a switch mode power supply, however I believe that the circuit will create it?s own problems. The device charges capacitors? easily but I have not found the trick of converting that energy to match the input needs of the device.

I happened to come across three solar cells that I was using in my early initial tests. The solar cells are Radio Shack Model -276-124, .55 volts at 0.3 amps ($4.99). I haven?t fully explored the possibility of the LED lights powering the solar cells. I hooked up the solar cells to the devices input terminals, used a 600-watt light to power the solar cells, and the solar cells powers up the device and all the LEDs as seen in the videos!

Just thought I would report on my status.

It  should  be  easy  to  connect  the  output  coil  to the  battery 

Do   you have any  capacitors laying  around?

here is a URL for a booklet  describing    a  capacitve  transformer

http://www.eagle-research.com/store/index.php?main_page=product_info&cPath=3&products_id=35

I  can't find my copy ...... so I can't give you  a formula

A little playing  around  with caps should  get you  your results in a short time

In general    you  will need a  cap  big enough  to   handle   the  amount of  power that you  wish to  return to the battery.

once you  select  your  cap to start with ......... you will need  more caps ......  if your output  voltage is  4 times higher than   you can use I would start  with a cap 4 times larger than  your  original cap .     

The  idea is that  the  voltage  will  change  depending on  the ratio  of the  caps   

once you have   the  combanation of caps in the right ball park .....  connect  the  output to a diode bridge ....... you  will have just made a pulsing  dc battery  charger   
I see no reason   you can't  run  this in parallel   with your   leds
