I brazed up my own charge controller
I have about 20 buck in the controller,
I wish I knew that before I did this....
what I did was monitor the volts and
have it blink green when it's low
steady green when it charged
red & green when it's over charged and
that triggers a dump load to a relay...
the load right now is some flood lights,
but I hope to find a more useful dump
load like a 12 volt water heater element

the windmill is a cute little GM alternator
rewound tighter & denser with neo magnets
so that it doesn't require a line voltage to
excite the coils... I figured I was pushing
30+ amps into the towmotor battery
when the nut backed off the shaft & things
flew apart <LOL> this was a proto type and I
didn't have a chance to properly meter it
before it came down for "adjustments"
I put ~ 200-300 buck into the project and
so I figure a buck a watt is cheaper than solar
cells at this juncture. I have a stirling engine
prototype that looks promising but the real
deal would have to be huge to produce any
real power, and once you get pistons the size
of 55 gallon drums friction plays an ever
increasing roll.

going greenie, well geenback$ anyhow..

Good luck with that. Sounds fun - you can get a small unit for ~$600,
though to power a full-time house, you'll need about 100 times the
power.

Depends where you are - the northeast is fairly shitty for both.

That's why they invented batteries.

No, I designed what is inside the mysterious black box in the middle
of the squiggly in and out diagramatical schematic whatchamacallit.

Ya know, it use to take more smoke to make devices function correctly.
When it leaked out, there was quite a bit to be seen. These days, even
the tiniest puff and your device is pretty much DOA...
