This page summarizes the procedure to build a DIY turbidostat and gives some calibration documents that may be helpful for future teams. Our whole philosophy is to promote the open-source hardware movement and that is why we compiled this manual, providing a useful guide for future igemers willing to build a DIY turbidostat. Hope you find it useful!
