Stop! Over insulating is a 100% sure-fire way to get unstable temperature inside, because it amplifies the consequences of any change in power dissipation. It is a classic mistake to build a 100mm insulated enclosure inside an office-like enviroment and end up having less stable temperature on the inside than the outside. Cinderblocks is a much better material for that scenario, because they have both thermal mass and inertia (= heat capacity and heat impedance) -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 p...@freebsd.org | 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 -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
