At the beginning: we were boring physicists - A Science Instrumentation Project

Recently, a Friend (a colleage) and Me are engaging a science intrumentation project as part of our formation as Physicist.

Basically, will make an experimental approach to the building of a Bioreactor system for the culture of microalgae. Our main goal is design a method to measure the microalgae concentration inside the bioreactor without opening it, which avoids the risk of contamine the microalgae culture. We detected this as an unsolved problem (at least locally) and that was highly motivating for us, so bad that we made a blog about it:

The interesting part is, that we will be using a Arduino Uno32 chipkit to automate stuff, (measurements basically) and a RaspberryPi to monitor and control all the processes, of course this involves circuit designing and building, also lots of programming, so we will be releasing code and maybe designs (licensed under GPL V3) in order to contribute to the community of free software and hardware.
