Hi
Does anyone have a schematic for a simple voltage reducer from 240v to 5vcc @ 0.5/1.0A , to fit onto a small PCB ! .

A USB adapter from a thrift store is the simplest answer.

Yes, never thought of that, thanks

I never build 5 volt supplies. I can buy good quality one far cheaper than I can build one.

I've used these before (below link) (about 2 cubic inches and $10 for board-mount supply) if building something to control an AC powered device but, if the whole project is 5v, it is is easier and safer to use the USB supply.

Now that almost everything runs on USB, it is easy to find a used supply.
