Back to the remedial English classes. "Many of them would have been more helpful if he were a better electronic engineer" is pure sarcasm - the implication is that they were decidedly unhelpful, mostly by concentrating the readers attention on childish tricks one can play with the 555, which isn't quite as universally applicable now as it was in it's glory days back in the early 1970's. Technology has moved on since then, even if John Fields hasn't. Being nasty about John Fields is my reaction to him being nasty about me - I respond to politeness with politeness, and to rudeness with rudeness. In principle I ought to end with some kind of disparaging comment about you, but your 1083 posting here are so uniformly undistinguished that there is really nothing to disparage. -- Bill Sloman, Nijmegen |

As far as I know Haffmans in Venlo are still making the unit (though they weren't selling as many as they'd hoped when I was last in contact) but I didn't take any examples home with me when I left them - platinum is expensive stuff and the electrode assembly (with its built-in glass bead themistor) cost quite a lot of money. -- Bill Sloman, Nijmegen |
