The current version of the spectrometer is contained within a wooden box but here are the core components.
1. Concave holographic diffraction grating.
2. Printed acetate slit from Public Labs.
3. Sony ILX511B CCD
4. Custom made circuit controlled by an Arduino Nano to operate the CCD and transmit data to a computer for display.
There is ALOT more to be added about the project in its current state and future progress but for the time being I am investing most of the free time I have to another project, PULSE: Profiler Underwater Light SEnsor., for the Hackaday 2016 prize.
