Get a power adapter for AC voltage or build your own with a 723. Not near
enough power to drive anything but LED's coming out of a serial port, and
it's not really regulated well at all. If it's sucking your 4 AAA's dry,
it's taking way too much power to be driven by the miniscule current a
serial port puts out.
Get a 6v lantern battery & clip the wires to the battery springs. Wear it
on your belt. That ought to get you a couple days of power at least ;)
