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?

If it's not exhibiting roughness you can probably save it with a
coating of latex.


I grew up in an area where water
lines were always metal (still are AFAIK), no plastics.

Metal lines in this "soil" go bye-bye... extreme salinity.



Hey, Mark! Doing anything interesting yet?


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

Right now I'm doing a chip design and some patent infringement stuff.

Make an 802.11G controller that can replace his 24V line.

Replaceable battery OR Inductive wireless charger where the operator
places the charging unit nearby every other week or so (as the
reporting software declares). That would be COOL!


Nah, why not go all out and design a fuel-cell driven radio link and 24V
switcher?

What the hell do you think I just said?

802.11G allows you to add it to your existing wireless network, and
that is easily controlled via simple software languages that are
about. The PS and battery IS in the device, of course, but said
battery requires recharging, hence my dual suggestion about doing so
manually or designing an additional device for inductively charging
them.

Where did you get lost. Fuel cells are still a ways off. Solar
arrays work, but not for lawn sprinkler heads. The inductive setup
would work fine. All is buried, and the charger can even be a bot
programmed to make its rounds to the heads for the purpose of charging
them.
