latest update on my SJ1 variant circuit with my DIY cell #5 as supply

after early discharge for first few hundred hours continuous operation of the SJ1-based LED flasher circuit, the cell terminal voltage has recharged to a slightly greater than initial value and now after 1000 hours operation it appears to be sustaining at that level
(please see graph below)

my control experiment with the 'sister' cell driving an equivalent load (fixed resistor) is starting to show a gradual discharge - i'll post that graph when i have data for a further week or so

so it appears that the dynamic load is necessary for the self-sustaining ability of these systems (my DIY cell #2 + my own LED flasher circuit has so far self-sustained since March - 5.5 months)

thanks

Wow!  very intriguing results, NP.  For the " SJ1 variant circuit"  to achieve this is very noteworthy: " the cell terminal voltage has recharged to a slightly greater than initial value and now after 1000 hours operation it appears to be sustaining at that level".

It may well be that a pulsed "dynamic load" is important here.  Awaiting your further results!

NickZ -- note that NP is doing what you requested essentially -- running with a battery and showing no drop in voltage... indeed, now an apparent small increase above the starting voltage.

Thanks, NP.

Thanks for your comment, Nils (EGP) -- glad we're on the same page on this.

Please drop by my topic Professor Jones and look at it for me. Don't pay attention to my rants but try to read the whole thing and see if you understand it. Thanks

Will do, Jbignes5...  I'm a bit behind in responses and even reading.  Fascinating research overall!

In my humble opinion skin-effect explains so called "over-unity" in Dr. Jones circuit. As all of you can see output current drawn in blue line (if i correctly interpret diagrams) has much higher frequency compared to input current. Higher frequency means higher skin-effect. So in reality output power can be 10x or so lower (say 15 times). Input current measurement is also biased but not so much because of lower frequency (say 5 times). So real numbers may be (just guessing):
input power - 2 mW
output power - 5 mW

Exact numbers depends on construction of resistors. So maybe real COP (coefficient of performance calculated as output power divided by input power) isnt 8 but only 2.5 (which isnt bad in principle).

You may well be right, Jan.  Thanks for comments.  What I've been looking at is -- other means to measure the output power and input power than using oscilloscopes -- as one can see in this thread as it goes along .

    Guys:
   The blinking led gives the circuit a chance to recuperate between pulses.  I get that on some of my BwJt circuits as the battery get low, it gets to a point where it will perpetual blink an led.  I didn't see the point in seeing how many months it would blink for...   But, bright led(s), after a month or more of non-stop use, are worth noting.
  A self-running BwJt circuit, is the only test that I can honestly trust. As these devices can fool any scope or meter. 
  Are these open or closed system devices? That is still my question.

  I think that a working combination of a crystal power cell along with an efficient BwJt circuit, is a realistic way to get to that perpetual self runner.  As I don't have magic shoes.

the circuit doesn't 'recuperate' between pulses

each flash discharges some energy from the buffer capacitor across the supply

what happens between pulses is that the voltage cell has to recharge energy lost by the capacitor

if you remove the cell from the circuit then the voltage on the capacitor will just keep decreasing until the voltage is too low for the circuit to flash the LED any more

if you connect a conventional cell as a supply then it will discharge also - yes, it will take a long time, but if you make a graph of the supply voltage against time you will see that the terminal voltage steadily decreases

i have done this (and i show a sample discharge trend for a NiMH cell with a similar circuit on my blog)

the difference with the results i'm posting above is that these are not conventional cells - they are more like the crystal cells you mention

the combination of cell and circuit is able to self-sustain its operation - ie. the system recharges, it doesn't steadily discharge

these cell/circuit systems are each contained inside metal cases, so they are 'closed-systems' as far as external electromagnetic energy is concerned

however, they are not isolated from the influence of ambient heat, and so i believe that is the source of the extra energy required to keep these systems charged

the point of this experiment is to confirm the principle that a system can operate without external supply of energy by the user but using a novel renewable energy source (ie not solar, wind, hydro, etc)

no magic shoes required!
