Spectrometer

He was doing a spectrometer Public Lab with a cardboard box and web cam, but I realized I needed a design that I could have control of the angle of incidence of light that otherwise had to do by eye , so once I put added hole in the top cover to esperimentar with different lasers and also in the side cover a hole with a cut where you can stay or piece of film cd.
Inspired by this original idea : https://publiclab.org/wiki/spectrometer

I intend to adapt to not having to remove the web cam so
