For a physics project in school I am planning on building an AC->DC rectifier with a 5V output (i.e. USB spec) but I'm having a bit of trouble with Diode Specs. Specifically the Zener Diode at the end that I'll need to get the output voltage smoothed correctly (the regulator). I'll need one with a 5V value and I can then try and tune the rest of my parts to that. So if anybody could give me a hand finding all the parts and specs I need it would be great (any data sheets greatly appreciated as I need references). I need a capacitor, 4 diodes (of same spec so 1 really) and a resistor to keep current down so the Diodes aren't burnt out. ANy help out there tempers?
