Hi! I'm working on a project, a battery powered PC, but without that picoPSU thing, don't ask why i dont buy it, it has many reasons. I just want to know, wich regulators do I need for it. I want it like this: BAT1 | CAPACITOR (make the voltages stable) |--------5vREG----CAPs------- |------------12vREG---CAPs--- |------------3.3vREG---CAPs-- So, the thing I want to know here, wich regulators i need to make this(wich model, or ?V and ?A), and also what regulator to make -12v and -5v(or how to make them)? Some info about the PC wich i want to be powered like this: miniATX board, no 4pin 12v AMD athlon 2200+ underclock to 1GHz, so no fan. integrated vga 1x512mb ddr 1x20gb 5400rpm hdd Please, answer if you really can help, not by telling "impossible" because it is not, or by telling buy picopsu, because then you cant read. thx.
