I get a negative reading sometimes with my volt meter if Im putting the red lead on the negative electrode and the black lead on the positive electrode.If that is whats happening no need to worry all voltmeters work like that.Hope I m not confused on what the question was?triffid
red lead is positve
black lead is negative

I understand, I've done that many times. When two are connected in series (so that they are charging each other?) one tests opposite what it normally does. Try it out for yourself! Connect two similar cells to charge each other (+ to -) and look at each one. Look at each voltage first though, so we can determine which one decides the polarity of the coupling... (If that is the case?) The voltage readings should be pretty low when coupled, at least that is what I got when I measured.
So now we have a capacitor and a what... transistor(?) too?? Hmmm...
I watched some of the videos (the 3 part blurry ones with good sound) and saw the graph about polarity going the other way. Not sure if that is what was happening when I made the test. I will try some tests tomorrow, it has been a busy day. I missed out on the dollar store...
Thanks for the links triffid! Gonna go watch the one you posted on the joule theif circuit and maybe wind a toroid if I don't get too tired heh heh...

Happy experimenting everyone!

I have some results to report
mixed aspirin cell---.14 volts
layered aspirin cell---1.34 volts
oldest aspirin cell now .41 volts down from.55 was .6 tops

My mixed cells have never worked for me.So Im not surprised about the .14 volt result its been 36 hours since the cell was made.The layered one is the same age.


I have some really bad news all of my tin can lid/mg cells have dropped in voltage.The oldest ones have dropped from .9 and .8 volt down to .25 volts.The newer ones in the panel 2 and panel 3 are worse off than that.I did seal one copperwire and magnesium strip cell in a plastic container over a month ago.I[size=78%] took it out today and its still reading a volt.Its twin I left out all this time is down to .25 volts.So maybe the changing weather is killing my cells?Maybe sealing every cell with wax or molten sulfur is the way to go?triffid[/size]

According to the three part lecture when voltages die its because the casimir plates are touching.Maybe heating them up will bring the voltages back up?By moving the plates apart again?triffid

I have some wax.I will seal my one good cell tomorrow.I need it to dry out for 48 hours.triffid
