OK this has probably be asked by allot of newbies but i feel in love p360s along time ago, at the mo im making a control panel. I what it to last me a long time and have the best controls as I'll be taking it to school for our LAN party's (and play some retro games) i now where to get the 5 volts from (I'm using an ipac) but first i need to know where ground it to and second will the ipac take the strain (i will most probably use the usb type)
Thanks for listening to me ramble :D

is this what it would look like
swithch gnd and volts around

Since nobody else is answering this, I'd suggest you contact Andy at Ultimarc.
He'd be the one to know for sure how much power the I-pac can supply.
If I were doing the project myself, I'd play it safe, and pull the power directly from the computer's power supply.
You could build a nice disconnect in one of your PCI covers that would allow you to unhook the power cable without getting inside the computer case.

I have two of those suckers hooked up to a the +5 on a keywhiz and it is fine. It isn't the ENCODER providing the +5 anyway, the +5 on the encoder is just a direct line to the +5 from the keyboard port.

I'm running 3 P360's, 3 volcano buttons and a rotary interface off of a single IPAC with no problems. However, my USB IPAC is plugged into a self-powered hub that can easily support 7 devices drawing the maximum allowed amount of power defined by USB specification. I wouldn't worry about the IPAC. I'd be more concerned about damaging the motherboard if you hook up too many items on a single port.
Also the P360 pins are high at rest and go to ground when the stick is moved. Therefore, if you use a different power source you need to make sure that it shares a common ground with the encoder and that the voltage is matched.
