How best to get 5v power for push button lamp?

I just used a



to power all my lights, lighted buttons, trackball

Thenasty:
if you ever to need more than one v5dc or need 12vdc, here is a good one to get (you will have plenty for future connections of v5dc & 12vdc)

misbehavens:
Again, this is a laptop powered control panel. I will have an extra USB port available. This would be easiest if the port provides the correct power. The power requirements listed on the website say 100ma @ 5v DC Per button. I only have one button. Someone mentioned that USB ports do 500ma max. Does that mean USB would suffice for this scenario? If not, does that mean I need to run power to my control panel?

I'm assuming I can take an old USB cord, cut it open and tap into the black and red wires and use that to power my button. Am I assuming wrong? What else would I need to do to make this work?

Also, the tapping into 5v header on the I-PAC sounds like a good option too, as long as it is appropriate and will not damage the board by doing something it was never intended to support.

Thoughts?

That's a pretty cool idea! How did you do it? Did you have to cut the end off of it?

Smeghead:
yeah cut the end off and you have your + and  - wire

I actually used a 12v as I have quite alot of lights connected to it, coin doors, buttons, trackball and some LEDs
Plugged into the smartswitch it all turns off when the pc is turned off

Did the same for my pincab, one for the lights and another for all the fans lol
