I, for example, have few suitable dummy loads at hand.
I have a load
resistor which came form an old Sun (4 ohms), though I'm not sure
whether it's between 5V and ground or 12V and ground - it I suspect the
latter, since it looks more like 36W than 6?W. (It could even be
between 5V and 12V from what I can tell, though that would be Weird.)
I actually do not even have a reliable voltmeter, much less the
properly working oscilloscope I'd want to check things like ripple.
Old disk drives, if they'll at least spin up, make good dummy loads.
The AC setting on a voltmeter will let you know if you have too much ripple
on a DC supply.
