Upgrading a cheap spectrometer. We added an optical fiber input port, a new higher resolution optical slit, created some accessories and even tarted-up the enclosure.

If you want a copy of the 3D files used in this video, please go to the channel page and find the e-mail address in the channel description. Send an email and we will reply with the files we used (might take a couple of days, we don't check that email address so often).

The original "Little Garden" spectrometer is for sale on AliExpress:
