Relay Driver

It seems like every other week someone needs to add a small relay driver to their BASIC Stamp project -- I happened to need one for a trade show this weekend (HauntCon if you happen to be in Dallas, TX).
I can vouch that the attached circuit works -- I built it as you can see in the photo.· To activate the relay, drive the Stamp pin HIGH.· To deactivate the relay, drive the Stamp pin LOW.
I've included RadioShack part numbers in the schematic to keep things easy.
