DIY power supply
Pirateguy:
so i finally got around to building a proper psu, and am wondering what kind of features i should put in it.
what i have to work with:
-desktop PC ATX PSU @ 300 watt
-various (regular) wall warts and PSU, incl one with selectable output (1.5v, 3v, 4.5v, 6v, 7v, 9v, 12v)
-various linear PSU from various devices
ZVS driver + flyback converter
-various small buck and boost converter
-lm317 regulators
-78xx regulators
-panel mount volt/amp meter (x2)
-panel mount thermometer
-pots, relays, knobs, jacks etc.
....i'd post link but for some reason my links keep getting molested.
just assume every item is the cheapest version of it on ebay.

OK, "so i finally got around to building a proper psu" sounds like it's done.. So show this Franken-Supply :-//
Pirateguy:
i got around to starting lol
still waiting for some stuff to come in and looking for an enclosure, and prolly will need to order some
final bits after deciding what all this thing will have to do.
but ready to start drawing up a plan.
for the moment the concept is:
-AC out 0-40v(ish)
-DC out 0-40v(ish)
-DC negative V out (?)
-AC constant current out
-DC constant current out
-DC out at typical battery voltages; 3, 5, 6, 7, 9, 12
-USB 5v out
-polarity inverting (with idiot proofing :P )
-volt/amp display
-thermometer display
-jack for connecting temp probe to thermometer
-function generator
-active cooling (have various sizes desktop pc fans for this)
-ZVS driver (?)
anything that should be on or not on this list?
also what would be the best ways to go about implementing?
MarkF:
IMHO you need to refine your requirements. You are setting yourself up for failure by trying to build the "be all" to "end all" psu. Get back to the basics and think about just a +/- dual DC supply (fixed or variable). You can go a LONG way with just a +/-12VDC supply for analog projects and a +5VDC for digital projects.
Afterward, build an independent function generator based on something like the AD9834 DDS and a small MCU.

for the moment the concept is:
-AC out 0-40v(ish)
-DC out 0-40v(ish) A 0-30VDC range would seem to be easier to obtain
-DC negative V out (?) A negative supply would be necessary for analog (op-amps)
-AC constant current out
-DC constant current out
-DC out at typical battery voltages; 3, 5, 6, 7, 9, 12
-USB 5v out
