This is a description of what I would like to do with, well something. Ideally, I would construct the circuit (easy) and have a computer record the output either continuosly or at regular time intervals. This project is really interesting to me. I am not sure where to start, however. Arduino or RPi?
In these instructions, the experiment is to test the path length dependence of Beer's Law. That is pretty cool, and I would be happy to do that. I would rather play around with the light source. I would like to stick a glowstick or a firefly in as the light source and use the same or similar detector. The results should give me some kinetic information.
