Voltage regulator--how to mount?

[JBotAlan]

Thanks for the input.

I might as well say what this is for...I'm planning on copying someone else's idea, wiring up the 5v from the regulator to a USB port. That way I can charge my iPod and at least power (not necessarily charge, due to some slightly more complex circuitry in the charger) my Motorola Razr on the road from a 9v battery (or 2). I don't honestly know what the draw is like to charge/power either device. I suppose I should do my homework before I tinker around any more...or I could do it by trial and error.

The more practical/serious use for this is stepping the 12v on the robot to 5v for my custom camera board. Again, I have no ideas as to how much this draws. I can pull out the meter and measure it, if need be.

Thanks (for taking me seriously after I said flat-out that I was mounting something in an Altoids tin...)

EDIT: [offtopic] Al, did you guys get your faulty pot wiring figured out yet? It looked like someone had cannibalized those PWM y-cables for pot wiring--every single one of those I've used has turned out defective, so I don't use them anymore. Had you seen that before Atlanta? And was that the problem you were having at Atl?[/offtopic]

Sorry if I seem a bit incoherent/rambling...I really should get some sleep. And yet I continue to type...
