| Imported post Coincidence - that's what this post is.
After reading one of Bren's posts last year I sent off for and rcv'd the Oxygen Hackers Manual (something like that) and have been intending on building myself an O2 analyser ever since.
Your post has prompted me to dig out the book again and read it properly and, with the aid of your notes, get something done about it.
