Groth has mentioned the part number for the Optical Isolators (DigiKey#
PS8701-ND)... I would presume (pending Groth's verification) that the transistors could be SMD and general purpose types. Resistors would probably be the same package I'll be using for the temp modules (0805 type).
Other than that there wouldn't be much to it... SMBus connectors on each side with the same pinouts as the temp modules, for consistancy.
As to the design... I'm looking at Groth's schematic from his
link. I would be interested if he has completed version 3 or has an updated version with recommended part numbers. That way you would get what Groth has already verified as working.
I don't know enough about electronic circuits to verify or trouble shoot designs like that. But I'd be willing to add that to the board runs so everyone could be happy... not just me.
