Spectrometer for Mobile-Phone ALS

Important Note: Print the Spectrometer.stl horizontally to keep it from breaking. This is a fixed wavelength spectrometer to use with the Ambient Light Sensor (ALS) of a mobile-phone. In here you'll find the main body of the spectrometer with a cuvette holder and the interchangeable part that comprises a battery CR2032 and a LED. You'll welcome to change any part of the design for your purposes, and I may give you a hand in that if you need! ;) Notes: - I use a round self-adhesive floor protector with a hole in it so I reduce the external light in the sensor and also allow the spectrometer to stay in place align with de ALS. - I recommend the use of the APP Shoebox Spectrometer for Android https://play.google.com/store/apps/details?id=appinventor.ai_billhosker.Shoeboxspec&hl=en_US Article: http://pubs.acs.org/doi/10.1021/acs.jchemed.7b00548 GitHub: https://github.com/VascoRibeiroPereira/phone-spectrophotometer <B>STEADY VERSION</B> Print the steady version of the LED block in horizontal orientation to keep it from breaking with assembling and disassembling the two pieces. I made this versions to keep it in place and maintain its calibration for a longer period of time (by stabilising the positions of the models)
