Go Go						Special activity (GoGo) [1]
Sensors			[4] See [3]			Connect sensors to audio input
Decode audio tone			[5]			Use frequency decoders eg. LM567 to control multiple outputs
Picaxe						A low cost solution, Linux programming environment available [6] though the chip and board is cheap, the USB cable is $30 [7]
Ti Launchpad [8]						Another low cost solution, "able to compile msp430-gcc on the xo-1.5 and use it with mspdebug to upload firmware"

Additional notes

Having an oscilloscope available is always handy when working with sensors. We may want to extend Measure to support sensors made available through Arduino, WeGo, etc.
