Simple Electronics (Hopefully)

I have been converting an old touchscreen kiosk into a jukebox.  The person that I am doing it for wants to have some sound activated led patches installed on the front speaker covers. My question is as follows.

There are 6 patches in total, they are normally powered by 2 x AA Batteries which should last about 6 Hrs, I am guessing that the current draw is 3v 200ma for each patch.

What would be the best way of connecting them all to a separate power unit (Thus negating the need to keep changing batteries). I presume that a multi voltage adapter that can supply 3v @ 1500ma would be capable of powering them, but how should the connections be made.  Should there be a unit that takes the input and splits it 6 ways, could it be done just by wiring all of the negative/positive connections in a single loop? Can I take the power from 5v on the PC PSU?

If anyone can advise of the simplest method to perform this operation (alternatively some elegant solutions would be nice). Either way I would be most grateful. If It takes making some sort of circuit board up please advise of part numbers as from Maplins.co.uk (I have one locally to me). One other thing, My soldering skills suck big time so simple soldering only

Do the LED's have a current limiting resistor? Sometimes LED's are fed straight from the battery, as the battery itself is current limiting.
If the do, just put them all in parallel, that is no problem. 200mA seems a little high. Are they super-bright? Guess 1 amp for the 6 should be ample.

Thanks, I shall give it a go, I have a spare 1200ma adjustable power supply. As I understand Parallel I should Connect the + side out of the power supply and split that 6 ways then do the same for the negative wire and connect them to each individual device. Cheers.

yep

I have this page bookmarked for when I'm ready to add some led's to my project - take a look:
