Hello. I'm looking to build a variable power supply to replace the "wall wart" I'm currently using. I have build one before, but my notes are lacking some specifications for some reason.
I have googled around and I can't find a good schematic to build one, I don't know what I'm doing wrong.
Finding components where I live is no easy task, they usually stock some common components, nothing too fancy.
For example, I wanted to build this Supply from Make Magazine:
http://makezine.com/projects/0-24-Volt-2-Amp-Bench-Top-Power-Supply/But I can't find a BR805D Bridge Rectifier in the electronics store.
I want to know with what individual diodes I can replace this bridge?
What about that mini volt meter? I have never used one, would any voltmeter be useful in this situation?
Also, if you happen to know a better, simpler VPS, please point me to the schematics.
What I'm actually looking for is a 12V or 20V 1A VPS with a voltmeter display.
Thanks
