Can you tell me what the little dots mean at the transformer...?
I have never wound a transformer before, much less made a switchmode supply, but I would like to try..
Also what would be a suitable wire thickness... max Vout will be about 260VDC but probably well under 10mA. |

| Polarity. If the end of the dot on one winding goes positive, the end of the other winding will also go positive. |
