low cost spectrometer use challenge

You may not have heard of the low cost spectrometer developed by a community of people called the Public Laboratory.  We have developed a $40 USD spectrometer capable of 3 nm resolution with a range of about 300-900 nm -


We have also developed a free, opensource software suite for analysis and comparison of spectra -


We are hosting an open challenge for using our device and are giving away $$$ -


I hope this is apropriate for this forum.
