I subcribe to many different online electronic industry newsletters and sometimes they have these really neat circuits but followed up with LOTS of math...which, quite frankly, gives me the heebie jeebies!!
Anyhow, here's a nice one that will run a small pager motor on 10nA.·
If someone has a chance to breadboard this, let us know the results!
I have to dig thru my pile of old cells and gut the motors out for a separate project and this circuit would be great for powering them!
anyhow, here's the link to the circuit
and here's the actual article
"Inside each and every one of us is our one, true authentic swing. Something we was born with. Something that's ours and ours alone. Something that can't be learned... something that's got to be remembered."
