I came across a post on about someone building their own automated film processor using a Lego Mindstorm for the conttroller. The post was on HackaDay (http://hackaday.com/2014/12/22/developing-film-with-lego/) and actually refers to two different machines built by the person. There is not a lot of detail here about exactly what was done but it is an interesting attempt.
