Hi ecogeorge,
The PV tracker circuit is new and at this present moment is under going alpha trials, and again comes from the Fieldlines Forum, I like it as it is simple, robust, and very importantly, designed and made by folk who want it.
Tracker Circuit, but the enclosure work is a bit OTT,

At present my design puts all its weight perfectly balanced on one load bearing seesaw joint point, East to West. Then another for 5 position declination adjustment, manually adjusted at present. But as you are aware i am a great believer in absolute minimal materials use.
Collecting apples today for the cider making weekend ahead, and also well in to making the Multi Battery Monitor Circuit PCB.
