Going up?

Archiver

My thanks to everyone that has unknowning helped me in my project
thus far. I have a "Board of Education" that I'm using to control
some servos and other sensors. This part of the project works
fine. Now, I'm putting this entire "kit" on an electronic mast that
raises itself 30' (about 10 meters) into the air. The motor for
the mast has an "AND" gate so that it won't move unless a constant
source is high AND an output from the BS2 is high. What I'd like
to to is attache a sensor on the top of my kit that I can use to cut
the output to the motor if I come to close to something. General
concerns are power lines and overhead structures. Beleive it or
not, I've seen people manually raise the sensor kit right up into a
bridge, a building, powerlines, etc... I've tried various leds
and proximity sensors but they either fail because of sunligh (wow,
it's 110 degrees today!) or they miss a powerline because of size.

Thanks,
Brian

I wouldn't hazard any advice about a rube gizmo being waved around on
a 30' pole next to a power line, other than don't!

Maybe try a simple bump switch with a long piece of wire soldered onto the
end like a whisker.
Just an idea.

Make that an INSULATING probe 'wire' if you even MIGHT be 'going up'
near HV lines.

Thank you for this idea. I had considered a well insulated probe
attached to a bump or push off switch but I think that actually
touching the powerline might melt the probe, if I was lucky.
Wouldn't it be better to just not touch it. In my enivorment I
can't help but get near the lines but I'd rather know if the
operator misjudged the height they are at.

Thanks for your suggestions.
