Once I did a circuit with a 650F cap that gadgetmall posted but I'm afraid using it cause don't want to charge it above it's voltage :-\ .
Is there a safe and simple circuit that if it goes beyond it's voltage can drain the charge or light a bulb for safety?
Thanks.

guruji

I am not sure how much  voltage the Ucaps can take.......I am sure that the  max voltage  acording the company is 2.7 V and not 3 V for a reason.

I am shooting for 2 to 2.5 V for mine
I like  a little safety margin.

I posted about my voltage control idea a few weeks ago........I was  promptly  told it  would not  work....... so I am not  going to talk  about it more until it is tested.
I  hope  to spend  most of this evening  building and testing it.



Other than the extra .3 V  I think the  zener diode  voltage control  ides would work .....at least with a small charger....... your zener has to be able to handle all the extra current.

This is my latest experiment. Somehow the 2 diodes (and the LED) and the larger extra winding helps replenish the supercap during circuit operation.

Don't laugh, but one of my so far very sketchy theories is that supercaps are more like quantum batteries than they are capacitors and that just keeping the "plates" at charge allows current to be drawn from the capacitor as if it were a battery, the extra energy being supplied by "ZPE", Radiant Energy or one of the many other sources physicists hate talking about!

(Note this is the same 6 Farad cap as before and the biggest change the the circuit is the extra toroid winding. (If this indeed follows my "theory" the unique diode arrangement just keeps the plates on the supercap charged. Due to losses in the circuit (and in the supercap) this circuit WILL NOT run forever (but it does seem my attempts are making for longer and longer runs!)

Hi Nieves thanks for that schematic I will try that. Resonanceman yes it's 2.7v; I will look forward to hear about your circuit when you test it.
NewEnergy that circuit is interesting can one use it for a 650F 2.7v Cap?
Thanks guys.

guruji, First, thanks for your interest in the circuit!

Yes, I would love to see what the circuit would do with a larger than 6F supercap (like for example a 650F).

The first thing is to charge the supercap with 1.5 to 2.5 volts (I do that with a 1.5V AA cell and the 6F supercap has no problem with it at all. I have also seen it done with 3V, but I WOULD NOT recommend that...)

I strongly suspect with the proper circuit setup the self-run time could be VERY LONG indeed. My little theory might even have something to do with the length of the run (again, I would not expect the circuit to run forever, because of component losses, but it could run long enough to get bored with it and end up putting it aside as a dim night light!)

(This also brings me to strongly believe a supercap circuit COULD be made to drive much more of a load than just a LED. For an example: a small personal DC motor fan?)

Overunity? No, but none the less a very practical energy device.

Hi Nieves that circuit works with no batteries?!
Amazing.

Yes, this circuit runs for quite a while without any batteries. The supercap needs to be charged first, but then a battery is no longer needed. (I still haven't gotten/tried a bigger supercap...)

I got tired of having to "ride" R1 during circuit operation to keep the LED blinking steadily so I added some "optical feedback" and the circuit now runs very nicely by itself (One must adjust R2 until stable operation is achieved.)

Flashing an LED for a long time is not really a useful practical device. Nor is it "cutting edge" technology. My smoke detector runs for about 2 years off a pp3 battery AND flashes the LED. When the battery gets low it flashes AND beeps for about 6 months! You put a lithium battery inside they last 10 years.

No OU here though of course just low power circuits. Back in the 90's i designed commercial app hardware to run processor, clock, 10mW transmitter circuit off 6 AA cells and it lasted 4 years. The average current consumption was a mere 265uA :)

This is not to say a Joule Thief or Stifler circuit can't go OU they can but be-careful you haven't just made a low power device and get over excited about it.

and how exactly does a simple blocking oscillator "go OU"?

Correctly working tuned toroidal cores go OU.  As the basis of Orbo, bob boyce, tpu, kapandze and hundred other things but it not the oscillator design  in case you are wondering.

great! where can i see this measured and demonstrated? because the orbo doesn't show it, nor does boyce, and there are no working tpu replications even with the best and brightest (poynt, grumpy, etc.), in their own minds anyways, working on it. same with kapandze and the "hundred other things"...

p.s. stiffler's circuit doesn't have a  toroidal core... nor does kapandze's.

Hi Gary . I am back . for a while . I have one of the 650f ultra caps charged by the 5 volt solar panel daily and by accident it's standing volts are 3.88 . It runs another circuit i build that gets its power from that bcap thru a blinking red LED . the other circuit is a jt-+ a sec to run one wire stuff . . Its running right now and really wont draw enough from the bcap so its OVER OVER Charging . but its not exploded yet :> I now feel safe with overcharging if that happens to 4 volts MAX on the 2.7 volt cap . Interestedly this cap is now one of my best ones . It might damage it in several years but they are now cheap enough to deal with it . there is a plug on the side of them that will leak out the electrolyte and pressure if it gets very high .

I am glad you are back

I hope you can stick around a long time


Thanks for the information about the voltage boostcaps can handle
It makes sense  most engineers build in a substantial safty factor.

I  have not  worked on my voltage control circuit sense I last posted on this thread
I have lots of other stuff going on.
I will pick up where I left  off when I get a charging system I like  working

When I get back to using boost caps I will have alot more confidence  knowing that the  boost caps can handle at least a full volt over their rating
before I was only charging them to 2 volts  just in case I accidentally went over.

I do plan on trying to hold mostly to the rated voltage.
I have to assume the people that  chose the rated voltage knew something I don't know.

Oh, dear... Toroidal cores can go OU?

WTF?!...
Ah,Orbo technology....

the thing i love about this circuit is with very few scrap parts you can bring light to homes that have never seen a bulb let alone electricity and because we use so low voltage it isent to hard to make that power if this little units with an earth battery could be sent to 3rd world country they life would be made easyer

here is the second firing and filament loads in place on My no good for nothing Distraction JT :) I got 4 Peltier modules today and they do get HOT! on just 1 volt . Feels so good ~~
Gadget
so you are using the jt to charge the super cap then running the standerd bulbs off the supercap well thats bloody good in my eyes as thorse bulbs wont run off a normal jt ok the cost of parts may take awhile for them to pay for them selves but ant that the same with every product you build or buy and to cop what a load of bullshit rules and angles to eaerly say it isent
