Schazamp finalized his USB power supply. It features the MCP1824S linear voltage regulator, a PTC resettable fuse, and an ON-NONE-ON SPDT switch. You can chose the output from either the 5v USB line or the voltage regulator.

    Why not an automatic switch? Like on the Arduino.

    There are also some good 3 pin switching regulators that are drop in replacements for linears.
