This is a portable Spectrometer based on a Raspberry Pi Zero 2 W with with camera and diffraction optics. In the beginning i had the plan to install a 320x240 pixel 3,2"-TFT, but it was unusable. The consequence of that was a 5" 800x480 pixels, witch is listed as extra project: https://hackaday.io/project/183135-protable-pyspectrometer This could be placed near an experiment, to observe some dynamic spectra, while operate the device from somewhere else. With the the size of this version i was very happy - its handy and fun to use with VNC on a mobile phone. .stl-file for optics mount is included here.
