The way you do it, is with a thermal converter. I've been playing around to see if instead of a thermocouple it would be possible to do the sensing by infrared light, and it looks possible but I have not spent enough time to nail it usably yet. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [email protected] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
