emergency personnel aside for a second, this doesn't seem right. seriously? there's gotta be some kind of physical problem w/ that...
oh, in case you're wondering, i'm not a medical professional
here's one that we're actually looking to use at the office. jeroen hoppenbrouwers has a great little write up (http://www.hoppie.nl/tempsens/) on building a temperature sensing array. students can build individual sensors for well within your $5 ballpark and the group can assemble the rs232 interface and whatever housing you decide to go with for just a little bit more. everything rolls back through the serial connector to an antiquated chunk of x86 hardware that you get from it department is getting ready to throw out. pick your favorite linux distro, install digitemp (http://www.digitemp.com/) and you're ready to start gathering scads of data for use with nagios (http://www.nagios.org/), cacti (http://www.cacti.net/) or your favorite rrd (http://oss.oetiker.ch/rrdtool/) based tool.
kids get to learn about:
-simple circuits
-open source and standards
-the power of cheap, effective systems
-how badly the building needs hvac work
-start to finish application of multiple layers of technology
