Experts,
All I need to do it provide an internal 5VDC to a project, and take AC in, fuse it, but internal as compared to an external PS.
Man was I surprised at how scarce cheap ones are! After all, $5 wall-warts come with them, so the xformer should be ~$3 neighborhood, or so I guessed. All I found on Google, Amazon, eBay, Mouser, Digikey, etc. were either north of $5 or huge! I'm only powering a uC and relay, and at most it pulls 190mA. I figured rolling my own PS was least costly.
I must have made a mistake, and will be happily humbled if someone has an idea which MFG can source these, or if I need to get a ton via slow boat...
Thanks!
