[visionlist] simple light sensing for vision science experiments

[Theo Veenker]

Dear Daniel,

You might want to try the TEMPT6000 sensor thingy from SparkFun. Whether you need to 
amplify the output signal (using a non-inverting opamp) will depend on the sensitivity of 
your EEG recording device for auxiliary signals. For a strong signal the sensor should of 
course be a close as possible to the stimulus source.
