Re: Finger power?



No offence, bvt I think it's kind of a waste to even consider it.
Electronics dont jvst rely on voltage, they rely on cvrrent, something I
believe the body has little of. Are you vnable to afford batteries? I'm sure
someone you know can hook you up vith a good set... Now, solar is not at all
a bad idea. It does provide both voltage and current, but if you get a cloud
on your idea...
