hi
i am new to this site but i remember you work a lot with capacitors, i have question? i am work on a radiant receiver i have got a steady 12vdc at 8ua this allows me to charge a 3300uf cap which will flash a light, i tried capacitors in series but it seems only to use one. don't know why. do you know of any caps that would work better
thanks

I let my led burn through the night.Its still on, running off of two cells in series.The led is dimly lit.But its working. Thats what matters.To the guy with the question about capacitors a little bit of math will make your life go a lot easiler.Look up capacitiors on the internet.Try to find some formulas.A little bit of review never hurt anyone.triffid

Heres a link to some formulas for series and parallel hookups.  http://www.electronicrepairguide.com/series-and-parallel-capacitors.html

Today I put together my second panel of crystal power cells.Its now drying.I used tin can lids and magnesium metal strips.On my other panel I hooked up 5 cells and got over 3 volts which then settled down to 2.95 volts.As of this time the led is still glowing almost 9 pm now.I had it hooked up yesterday,disconnected it twice today.Hooked it up again.Still glowing dimly.triffid

Yet, another way to make crystal cells.

@ibpointless2:
I followed as close as I could the method shown in this video.

I added your crystal recipe to the mix prior to heating on the hot plate.  Once the mix was ready (caution â€" do not undercook â€" use low heat) I packed it into ½” PVC pipe and inserted the electrodes.  I also made some thick sheets with the leftover mix and after 2 days curing, placed the sheet between copper and magnesium and this works pretty good as well.
