    I think your issue is due to the light passing through the liquid (and not tripping the sensor). I’ve been able to detect small objects moving at about 300 m/s with these but the trick is to fully eclipse the detector. If your liquid doesn’t absorb IR is will be essentially transparent to the detector.

    I had the exact same problem. Follow this schematic for adding a 0.1uf cap b/w RTD on an FTDI cable and Reset on the chip. http://thetransistor.com/wp-content/uploads/2010/02/Minimalist-Arduino-Rev01-Schematic.pdf

    Also choose the UNO instead of the Duemilanove as the instructions would seem to suggest. This fixed all of my problems and doesn’t require timing the reset anymore. I’m on OSX 10.7 using this kit and FTDI 5V Cable.

No public wish lists :(
