Noob help - How to get all power from Laptop?

I will be powering a trackball with one USB port and the other would be for the 5v light for the coin button.
I have an KeyWiz-ST on order which will be connected to the lone PS/2 port.
I'm really clueless on wiring and power since my order hasn't arrived yet, but does the KeyWiz-ST offer a 5v line of power to power the LED of the coin button?
If so, I could then replace that 5v usb hack cable for the coin door LED and get a mini USB keyboard for troubleshooting. If not, I have a USB hub as well so I can see if that works.

I use a wall wart to provide my 5v and 12v sources. I used 2 in my last system. 1 for the fan, and the other for the coin buttons. Just find one with the right output and your golden
Ritalin:
Excellent idea!
These are the types of items I regularly see at the flea market, so I'll keep an eye out for the 5v output type.
Thanks for the pic too, that really helped me visualize the item you're talking about.
Thanks!
knave:
Be sure to measure the output of any wallwarts you intend to use...many of them are unregulated and run hot.
A 6v supply that I tested was running ar ~9v.

Rather than use the laptop for power, you could just pick up a powered USB hub for cheap. I use one for my coin door lights, which are LEDs hooked to USB cables. (Doesn't even need to plug into the computer)

Kind of OT here. Was this thread edited? I left a response, took a nap, refreshed the page and now it's gone ???
