I've seen a test in which the altimeter and servo were put in a large jar, with a straw sealed into the lid. Close the lid and suck gently on the straw to drop the pressure in the jar (it doesn't take much) to simulate a rise in altitude.

does anyone have any information on trying to use the current launchpad MSP-EXP430G2ET.
I can't seem to find anything.
