Only relay I have found to safely trip with stamp is
tiny magnetic reed relay. You can find them at
radioshacks still, make sure you get 5volt version and
not 12 volt.

What if I drive the relay with an inverter or buffer? Will it work
then?
You may drive a more powerful relay with a transistor. Just make the stamp drive the transistor, which you wire to drive the relay.

Depends on the current required by the coil. It's not likely that
you're going to find one you can connect directly -- use a transistor or
other suitable driver to be safe.

The BS2SX stamp can source or sink 25 ma. There are some 5 volt reed
relays that meet that requirement. I used a Tyco Electronics
OMR-106H, V000 SPST-NO reed relay with a nominal coil current of 24 ma
in my last project and it's been working fine. Remember to put a
diode across the coil to protect the stamp from the voltage transient
when the relay is turned off.
just use the pin to drive a 2N2222 transistor or for more power a
darlington to drive the relay....

Can it do it safely without pulling to much power?
