Well, the frost out here took its toll. Need to re-plumb and relocate a sprinkler valve. Poof ... phssssst. Anyhow, like most engineers I've got lots of CAT-5 sitting on two spools doing nothing. I know, I know, it's not what you are 'sposed to use outdoors but it'll save me a drive into town.

What happens to CAT-5 outdoors when part of it is buried in the soil and another part is exposed to the sun? Regular stuff, not plenum rated. It's going to get 24V, not much current, probably 250mA or so and I can parallel all the pairs. Any experience?

BTW, I have in the past used indoor telephone line outdoors and it lasted forever. But that was much older technology, four non-twisted wires in a gray jacket. Then I had non-stranded electricians wire as an antenna, high up there, looked like new after 15+ years. Amazing.


For a "temporary" outdoor suspended run of CAT-5 which has lasted 5
years, I painted the jacket with white primer paint. This is located
in Central Calif. Stuff I inspected after 2 years was still in good
condition. Maybe primer paint, then a coating of latex.

Yep. Latex will even protect exposed PVC pipe from the Arizona sun.


When the water main before our meter busted open they replaced it with PVC. That surprised me. What surprised me even more was that they left an 45-degree joint exposed and that shows a wee chocolate-color by now. Does that mean it's going lalaland? I grew up in an area where water lines were always metal (still are AFAIK), no plastics.


Hey, Mark! Doing anything interesting yet?


Are you back to chips now or did you take a liking to discrete stuff again?
