Hello,
Adding some updates here, unfortunately not good.
I dedicated this entire weekend trying different ideas for using the voltage provided by the cells.
I wasn't able to obtain any current with that voltage.
I even tried with a Joule-Thief I've built. I know the Joule-Thief is using current to boost voltage so in this situation it was unlikely to work but I thought it's worth a try:
It didn't worked, the LED was off.
One thing I noticed is the cells can boost the voltage of dead accumulators. I have some 1.5 V AA and AAA rechargable batteries which are very old (a few years of use) and my charges are showing them as defective and are not able to charge them anymore.
So when I put one of those in series with a cell (and a non-polarized capacitor in parallel with their output) there is some kind of symbiosis between them, meaning the battery is providing some current and the cell is providing extra-voltage so they can power 1-2 LEDs for a long time.
In this image the rechargable battery have about 1.2 V:
But seems in time the voltage is slowly decreasing, about 1-2 mV within 12 hours so I guess it's not gonna run forever. Even if this configuration gives the capability to power 1-2 LEDs (which the battery itself could not do) and probably a much longer time than the energy of the battery itself would do.
One last experiment I intend to try is to let a cell load a capacitor and to use a transistor commanded by my signal generator to discharge that capacitor at some intervals in a resistor to see how much voltage and (if any) current is in those discharges. Maybe that could make a LED blink at some intervals, that would be a way to use cells' voltage.
I'll see how it goes, I need to find some time to prepare build the circuit and to do the experiment.
Other than that, for now I'm kind of out of ideas so I will put these experiments on hold. Maybe in time I will find possible ways to use these cells.
I dedicated a lot of time building and experimenting with these cells, it's time to continue with my DSE experiment.
In parallel with the prepation of this last experiment with the cells I'll start building that customized capacitor and prepare the next experiments with my DSE device.
Regards,
Fighter
