Hi Ed,
Strangely enough, I’m also a Mechanical Engineer working on biodigesters, and have just started learning electronics with the Stalker.
Have you had any luck with data logging so far? I’m going to be logging temperatures, maybe pH and flow rate (through the heat exchanger). I’m struggling so far; I’m trying to use the stalker as a shield on a Seeeduino Mega. If you have any insightful information about getting these things up and running I’d be greatful to hear it. Maybe we could chat about biodigesters too?
Cheers,
Iain
