[OLPC library] Get involved - Measure Activity on the XO (Edward Cherlin)

[John]

Students at Colorado School of Mines cobbled together a thermister to  
gather temperature data for their LEGO computer. I suppose all that  
would be needed when Measure is interfaced with USB, is a connector  
for Measure to do calibrations on the XO?
