So I was surfing ebay minding my own buisness and boom.... I find this...

MY BAD EDIT: Posted wrong line

What do you think? for mounting on control panel:

If you need to measure dc voltage it'll work fine. I personally see little value in having a display tell me dc though. I measure that with a meter when setting up my adjustable power supplies and once they are set they are good.

One on hand, I agree: if you feel the need to constantly monitor a DC rail you're probably feeling guilty of doing something wrong and the better part of valor would be to just fix it

On the other hand: IT HAS BLUE LEDS! AND IT LOOKS COOL!
I could totally see someone sticking one of these on one of them there fancy control panels, just for the cool factor...

Cheers!

Ah, ok, the revised link points to something perhaps more useful in that it could monitor line voltage.
Otoh, how often is line voltage an issue?

I take it you originally posted a link to something else by mistake?

Anyways, looks like it would fit the bill to measure amps and AC voltage and take up a lot less room than 2 separate meters. Probably a cheap piece of Chinese junk, but you could buy 8 of the damn things for the price of better (read: more expensive) ones.
