Experiments

This is a list of community-generated guides for experiments using your spectrometry setup (either a starter kit or a modded design) toward specific applications. Some may be more reproduced -- or reproducible -- than others. Try them out to build your skills, and help improve them by leaving comments.

Purpose Author Time Difficulty Status Goal
Wavelength-calibrate with a Compact Fluorescent Blub (CFL) @warren 10 m - 150 replications Try It X replications
Scan sunlight @warren 10 m - 80 replications X replications
Compare different concentrations in a liquid sample (Beer’s Law, absorption) @straylight 4 h easy 0 replications Try it X replications
Extract samples (tomato) with ethanol @cfastie 2 h easy 0 replications Try it 5 replications | 3 reviews
Compare blends of olive and peanut oil @ygstc 3 h moderate 0 replications Try it X replications
Oil testing @gretchengehrke 2 h moderate 20 replications Try it X replications
(draft) Collect and concentrate oil sheen @matej 6 h difficult 1 replication Try it X replications
(requested) Determine effects of weathering on oil samples - - difficult - -

Guides should include a materials list and a step-by-step construction guide with photo documentation. See an example.

Hardware Mods

Have you added to your starter kit, improved it, or redesigned it? Show others how to take it to the next level by posting a build guide here:

Mods should include a parts list and a step-by-step construction guide with photo documentation. See an example.

Builds

There’s a lot going on in open source spectrometry -- if you’ve developed another open source design you’d like to show others how to construct, post it here!
