Quick revision to Desktop Kit instructions!
A follow-up -- the print instructions which shipped in the Desktop Spectrometry Kit ($35) contain a small error; they show the webcam being focused to 3" away, but in fact that distance should be 9". The online instructions have been revised and if you've already built your spectrometer, it's not hard to change. (download a revised PDF here) Your spectra should come out much sharper! Something like this:
Also, full instructions with build photos and lots of helpful troubleshooting tips are coming together now on the Desktop Spectrometry Kit wiki page. Check it out!
Thanks and sorry for the trouble!

This completely egregious "steampunk" spectrometer is made from polished aluminum, brass, and finely finished, laser engraved wood. It's functionally identical to the "countertop" model, but has enough polish to make Isambard Kingdom Brunel proud. Don't back this unless you are a) feeling sooo rad or b) trying to support the Public Lab nonprofit.Estimated delivery:
