Microwave Transformers and PICS
Made progress on making the Welder, and making useful things with PIC microprocessors.
Took a old microwave transformer and chiselled out (none to neatly) the secondary windings and put in 3.5 turns of heavy wire, 4 gauge I think (???) that I had lying around.
On 112vac it outputs 3.96vac. Target voltage is 4v so that is good. I might run it on 240v because the omron solid state relay I have is rated for 200-480vac, it does seem to work fine with 112v lighting a lamp. I think that to run it on 112vac will cut it's 30 amp rating in half. I have no idea how much I really need for the spot welder.
Pic Basic Pro seems to work as advertised and now I can actually program (clumsily) a PIC!
