You're welcome to drop them down or pop them in the post, I've got a lot on at the minute so would have to do them inbetween other projectsI did wonder that. I've got three more 1/2" fittings and the 4" flange for the heating element still to do as well, really not looking forward to that.
I might not comment much but I always read your updates so keep posting!New thread should get seen more, don't think anyone's still reading this, it's taken me too long.
I was probably going to get that same Ethernet SPI module and make a hat to hold both that and the ADC. It looks like there's a big shortage of Pi's at the moment, the only one not sold out is the 4, no Zero W's to be found for sensible money anywhere.
