First off, I'm a mechanical engineering graduate. It's been literally years since I've had an electrical class. Feel free to treat me like a bumbling moron.
Second, I'm sure this issue has been covered before, but I can't find anything SPECIFIC. Perhaps I'm not using the right search terms . . .
I'm modifying an alarm clock of mine. It is powered by a standard wall-wart type power supply with an input of 120VAC and an output of 9VAC @ 900mA. So far, I have been incorrectly assuming that the output was 9VDC - I've simply never seen a wall-wart that goes from AC-AC. My project requires 5VDC (though higher is fine - I already have circuitry in place to handle higher/unstable DC inputs using a Zener diode), and amps can be fairly low. How do I convert 9VAC to DC?
Thanks!
