Mick,
I picked up a gen 3.0 on gumtree for a lot less that the cost of a SmartPID and without the challenges of building/programming the Craftbeerpi.
However, this site has a nice build and contains links to the parts you need for the build...
Hi Gus,
How did you go with this? My old v2 board carked it and I'm struggling to find spare parts.
I've only just found out about the CraftBeerPi, would love to know how it went as it may be my only alternative.
Cheers,
Steve
