« Back to Spectrometry

After a few years, we're returning to one of our oldest kits to update and improve it, building on lots of community-contributed ideas, improvements, and refinements. This page collects resources, questions and activities related to the design.

Quick start

To get started assembling your spectrometer, try:

Design goals

Our goals were:

  • more rigid/robust
  • printable on non-black paper
  • easier to cut out with just scissors
  • put more of the instructions on the object itself, like on the Antikythera Mechanism

Keep in mind -- this is the "introductory" design intended to onboard newcomers to the project, so we're trying to make it as easy as possible to build. Once you've made this, you're ready to move on to more complex projects, like scanning, sample preparation, and more robust designs.

We haven't gotten all the way there on every goal -- we'd hoped to make a version that required no glue -- just locking tabs -- but we just couldn't keep it small enough to be printed on a folded-in-half letter sheet. See this note, this, and some of these photos for my process of integrating all these changes, and see this page for some of the many many people who've contributed.
