RGB Buttons on a 4p build

Not necessarily. You have to check the ratings of the particular LEDs you'll be using. I know from experience that I couldn't hook up two individual RGBs to the same ports on the PACLED64, as they would draw more current than what the outputs were rated for. Send Andy and email and ask him if you'd be able to double up LEDs on some ports with the LEDs he sells.
Kupoppo:
Whoops, and NOW I find Jace's post from August where he compares all the different RGB solutions.  I think I've more or less got the pieces straight in my head.  Thank you especially for turning me on to the output limitations on the controllers.  May need to double up on PACLED's, but hopefully the next post I have will be an announcement of "Hey I built this" :)

Got a lot of ideas, but more or less I'm trying hard to trot that line and create a feasibly functional 4p arcade cabinet that doesn't LOOK like a monster, looks more like a... well... arcade cabinet.

Thanks again Nephasth :)
Nephasth:
No problem. And that post you're referring to only covers a few of the options out there. Keep digging, the design process is a lot of fun.
RandyT:
Two LED-Wiz's will do what you want, if you want to use multiple LED's on a single output.  The LED-Wiz can drive up to 25 LED's on one output, so doubling, tripling, etc, won't be an issue.  It also has enough current to drive cabinet lighting, high output trackball lighting etc., should you be able to configure the panel in a way to have some outputs left over.

There are many examples on the forums showing how this can be done.  It's pretty simple once you get a few of the basic principles down.  If you still are unclear, there are lot of good folks here with the experience to get you over the humps.

Kupoppo:
Thank you Randy, definitely some food for thought as that'd solve a few other issues :)  I guess my button quantity is kind of odd with 24 buttons I'm hoping to light in some combination.  Really my purposes would be best met by a 72-output controller (giving me true unique buttons in my 4x6 setup), so it sounds like I may just have to bite the increased cost and either double up on PACLED's or triple up on LED-Wiz's.

So I know this is off-topic, but seeing your "Friends don't let friends hack keyboards." text I have to ask - all I've been seeing out there has been keyboard encoder after keyboard encoder after keyboard encoder.  I've about resigned myself  to taking apart a few joypads - any better suggestions?
