A quick test of concept, my spectrometer is made from toilet paper tubes and yellow duct tape (hence all the yellow). Just a spectrum of daylight on a cloudy day.

Operation Date Description

Operations enable reversible modification of data -- they act like filters which process the data. The graph you see above represents the data after these operations have been run. Delete them to undo their effects, or to apply them in a new order.

  • The thumbtack symbol indicates that data has been saved in a snapshot upon running that operation.
  • The symbol indicates that the operation's data snapshot is being referred to by another operation. Click it to learn more.
  • Operations with a #000-style suffix, like subtract:3243#2414 are referring to a specific snapshot (in this example, #2414) of another spectrum. Click to learn more.

Thanks! The device toilet paper tube spectrometer is pretty crude, I just made in about 20 minutes to see if I could make this work. I have a new spectrometer in the works now, pretty much the same design as the one on this site made from a VHS box, but just in a cardboard box. I might be able to post some pictures of both later, if I can figure out how. I'm still trying to figure out how this site works ;)

I tried to post a pictures on a note from my dashboard but it didn't work. I'm not sure if I did something wrong or if that's what you meant. So some pictures can be seen here:
