Public Lab contributor Nelari just posted a new research note entitled ' Split DVD – which part to use for spectrometer':
Read and respond to the post here: https://publiclab.org/notes/Nelari/05-25-2019/split-dvd-which-part-to-use-for-spectrometer
I split the DVD that came with the spectrometer kit. There are now four parts:
the top side, dull
the top side, glowing with rainbow colors (the opposite side has text)
the bottom side, clear with a purple tint
the bottom side, glowing with rainbow colors
Which part should I cut for the spectrometer?
Thank you for any tips!
