Hi, I was thinking about cutting a usb cable, put 5V and Ground on an end with a regulated voltage source, and connect the other end to the Arduino USB input. Is that a bad idea? What should I do with the data cables? Connect them to the ground? With a resistor? Thank you.

Power supply by USB with a regulated voltage source?
