I am looking to rig up a kind of extractor system, ghetto style in my Garage but using 12V rather them mains. The reason for this is I have quite a lot running on the mains although not usually all at the same time, so that's not so bad but I am thinking "green" and hoping to charge a battery to run it form a Solar panel.
I did do this once before (Without the panel) in an old garage I had and it worked fairly well so long as it was plugged into the mains through a battery charger but that kind of defeats the purpose. Also it would spin like hell when you switched it on but gradually get slower otherwise until the battery was completely flat, which I would prefer not to have.
So I am hoping to find some kind of voltage reducer/regulator that I could use with it, I suppose ideally with 2 or 3 speeds the fan could be run at and just an old vehicle radiator fan which I will build some kind of cowling for to the nearest source of fresh air. I am able to do 12V wiring, mains not so much unless I have detailed instructions, can anyone recommend what I should use though and how it should be wired? What I mean is what kind of voltage reducer, where would I get it from, scrapyard, E.Bay? Thanks
