coming soon, first experiments by Andy and dusjagr and GaudiLabs Open Fiber Spectrometer looked great... see more details on DIY spectroscopy
Turbidity Meters

Pretty much the same as below, just made new designs, larger and easier to produce locally here in Yogya. added speaker and VU meter extension... testing it now!

Some bugs in the cuvette:

Tests with Bengt et al
It woooorks!
we finally soldered a mini-jack plug to go directly into the line-in.... muuuuuch better quality than through the air :-) who would expect that!
We made various tests the other night, trying to have the Baby communicating like a modem, bliip bliip bluup, first using a small piezo-speaker or the hi-fi in the living room. it's looking good:
the free software Sigmira is kinda useful to test http://www.saharlow.com/technology/sigmira/
Bengt had to modify the SoftModem library to work with the attiny85, some different names of the PORTs and TMSKs and experiment with different frequencies for the carrier and baudrates.
you can easily check the signals also with audacity. display as spectrogramm and do spectral analysis.
FSK-Baby
We had to do some changes to the SoftModem library... more soon.
With the following speed setting it works fine, but slow:
#define SOFT_MODEM_BAUD_RATE (50) #define SOFT_MODEM_LOW_FREQ (600) #define SOFT_MODEM_HIGH_FREQ (850) #define SOFT_MODEM_MAX_RX_BUFF (32)

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

Commercial Turbidity Sensors

some links and snippets
The Turbidity Module uses an IR LED with a wavelength of 860 nm to meet ISO 7027 requirements for Turbidity water quality measurements.

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.
