Spectroscope

coming soon, first experiments by Andy and dusjagr looked great... see more details on DIY spectroscopy

Turbidity sensor

simple light absorbtion at a specific wavelength of a cheap laser, easy detection of turbidity.

UV-vis absorbtion spectrophotometer

UV-vis spectrometer, would be even nicer, added white LED instead of laser, changing colors with simple light filters. but they have almost no UV, so added a UV led. turns out the CdS photoresistors are really slow and not very sensitive at UV also...

also we are working on a hacked line-scanner to look at the spectra after passing a prism or grating.
