until now I had made all on my own, used parts, from old electroncs - old tv, old computer pcb's -
that were quite easy to achieve - and some electronics from china,- pretty priceworthy...
Now, (in the last month:)
to silverze the mirror i looked a loong time to find a better solution as 'aluminiumfoil, and found a receipt for to silverize any surface - wood, metal, and plastics, as epoxy...
So i polished the parabolic dish, and i tested the siverizing soutions on some 'random round piece of glass, to see if the chemismus worked..
I will go that way further on and need to test different concentrations - and, I need to have a double simultaniously spraying device and an air compressor...
(any who can send me over ? ;) )
I worked with pressurepump gardensprayer - but I noticed that the spray, the drops are too big, I need a finer mist of them siverizing solutions onto the surface...
