openSpectrometer, OSH Park shared projects?

Tracy Allen

Poking around on the shared projects there, I ran across this openSpectrometer 0.2. Uses a Propeller, a Toshiba CCD and a Wolfson WM8253 CCD digitizer.

Shared projects on OSH Park (of which there are many) come with practically nothing in the way of links to follow. Author (apart from a screen name), parts, schematics. Does it work and how to follow up?

Not much information there and no code. It uses a linear CCD meant for scanning bar codes. I guess it could be used for optical spectroscopy in the 400 - 7/800nM range. Not sure how sensitive it would be. I would say the electronics and code would be the easy part of this. The optics would be the major part of this project.

His comment "The last few years up to now" gives a description of what he's planning to do.

Domanik, thanks for finding that link. It looks like he is striving for highest performance, almost professional optics, not yet incorporated. I'll follow along.

I do have one of the DIY spectrometers from Public Labs. It uses a wedge cut off a DVD for a grating, behind a simple slit, and a USB webcam to detect the light. Nowhere near as sophisticated, but educational.
