hi all,
I'm trying to make a small AC/DC converter to power my arduino smart outlet I am building. I want to tap off the line voltage that is right there in the outlet to power the arduino so I can encapsulate it all in a gang box. I've been looking around the web for info but seems like the only thing I can find is people taking apart old cell phone chargers and using the board(s) inside. Well this could be fine and good it would be nice if I could simply recreate what is in a typical cell phone charger on a small board. Is this possible? Does anybody have a schematic for this type of thing they could share? Thoughts in general? All the "normal" power supplies have big transformers in them and that won't due for this small application.
