Hello,
About me...so you know where I am coming from. If you don't want to read, skip to the end-ish...
I'd like to start off my saying that I know next to nothing about electronics although I am eagerly reading the All New Electronics Self-Teaching Guide right now and it is confusing but I am slowly understanding it.
There's a lot of equations in that book. Perhaps some of you may have heard of it, read it. But, I am going to attempt to do a very small project and that is building a simple 12V power supply for...anything that might require 12V.
So I am searching over at Mouser.com, the site which I have had the best luck with and I am looking for some nice capacitors. I am an avid PC hardware enthusiast trying to get into electronics and nothing draws my eye quite like aluminum organic polymer caps. These caps are pretty much worshiped on the PC spectrum. (AKA solid state caps).
But, don't really know squat-diddly about electronics. What kind of voltage rating do I need to use on a 12V supply sipping power straight from the wall. No batteries or anything.
Solid state caps only go up to about 50V or so I have seen but standard electrolytics can go up to 900-1000v.
What the heck do I need? I have some schematics, just trying to determine the parts. This is the schematic: http://www.instructables.com/files/orig/F6Z/DVT6/FKVQJ2RJ/F6ZDVT6FKVQJ2RJ.jpg
Also, and I am sorry if I am asking too much, the primary/input rating on a transformer should be like equal to the wall? And the output maybe around 35V?
Thanks.
