As a bit of context regarding this, to make the replies more useful.....
Beat Heeb, the guy that makes the replacement boards for the Distox2, has sold out. At the minute he's unsure if he'll be able to make more - I think because he's struggling to source certain parts and because the x310 is being discontinued, its not worth redeveloping the board with replacement parts. There is nobody else making these boards, he was the only source.
Hopefully somebody has a spare board lying about that Andy can buy, but as they're ?180 I'm not optimistic. If another board is found, I'm more than happy to do the work to put it together and as Andy said, I have batteries available.
