An Arduino-powered spectrophotometer

arduino spectrophotometer

So, we made an microplate spectrophotometer.  This was our first proper build and was the final-year undergraduate project of two excellent students: Peter Elphick and Ed Tye.  They managed to build this working 96-well plate reader from scratch in 6 weeks, with no previous experience.  Pete focussed on building a motorised x-y table for the plate reader part, and Ed did the absorbance reading and the data logging.  The finished machine worked (!), although it does take 75 mins to read a plate.  You can see the full details and step-by-step instructions here.
