I currently have a small (1.2 KW) PV solar array, and I am wanting to add a homebrew microhydroelectric installation on my property. For a test, I put about 80...
We use a driven well point from Lehman's (about $70). It's made for driving a water well up to 20' but we just lay it in a natural hole in our brook that stays...
I also have been eyeing the stream that comes off the reservoir next to my house. A driveway cuts infront of the path between me and the stream. I thought I...
Hi all, My father has a solar heater for his swimming pool. The problem with it is that (obviously) it only heats the water when the sun hits it. The rest of...
Hi, I would check out some companies that supply equipment for lawn watering systems. Most of these systems use solenoid valves to open and close water flow...
What we used to use was a solar panel that ran a seperate pump. A hose dipped down to the bottom of the pool where the coldest water was. That led to a solar ...
Try a thermostatically operated 24 volt Zone valve. These are generally used in hydronic heating systems. It uses a 24 volt sir conditioning termostat, and a...
Hello Paul I had a nice setup on my mothers pool. I used a 60 watt PV panel to run a DC pump that circulated the pool water through the solar collector only...
Thanks, both of you, for the suggestions. I will see what I can find. --Paul woldgood9 <woldgood9@...> wrote: Or how about a thermostatic valve...so...
I have known Al Snaper for a long time. Some of his inventions are very good and some are not. He has no experience in wind power (until now) but I don't ...

Hi, I'm looking for some sort of solar powered device that will make a continuous noise (like maybe a clicking sound) both day and night. This is to provide a...
Hi, Just about any oscillator circuit can be made to "click" by adding a capacitor to the circuit. Most electronic supply sources have cheap oscillator kits...
Old small radios are cheap, plentiful, and use a surprisingly small amount of power. (Actually the cheaper the better, less bass.) If power is a high concern,...
Joe, I agree the solar fencer does make a sound, but they run @ $200/ea... kind of expensive clicker when I'm hoping for 2 on each gate. I currently use solar...
Hi Kami, Try looking for an electronic metronome kit. Shouldn't cost more than $8 or so. Basically an oscillator made to click. They used to sell these kits...
I built something like that for underwater use and battery powered. It would last about a month on a 9v battery. It would be nothing to convert this to solar...
Hi, Even simpler than using a 555 multivibrator circuit is to "force" a transistor to oscillate. I created a simple circuit when I was a kid in elementary...
Hi again, Another source for this circuit module is micro wave ovens. Most still use that beep-beep sound to let you know things are done. You can often find 3...
Passing this on to a few groups where some might find it of use. If you do this rebate through the UTIL (UNS/TEP) then you have to stay grid-connected I think...
Wow! I reallly appreciate all the input. This is a great group and I'm going to try a couple different approaches. But I wanted to ask about a slightly...
