RSSA 555 timer based, lights following robot used to pull cabling through an air duct...
Brian writes in...
Recently, I wanted to network my media center in the living room of my apartment. I was not satisfied with running an ethernet cable down the hallway and putting holes in the wall was not an option. Thats when I thought of running the cable through the air duct, my 555 based light-seeking robot came to the rescue!

That is, of course, plenum-rated cable?
Safety first, y'all.

Actually running cable through air ducts or over raised ceilings without proper support is nearly always against the fire code. Not that it necessarily matters for your home, but something to keep in mind.

I guess a fish tape was just out of the question... no?

Awesome! You should mod it to clean the duct before you get Legionnaires disease.

What music is this? I see it on lots of things and I really want to know where you get it.
Thanks

Thanks for the feedback guys! I know that heat should be of concern when running cables and I definitely think that anyone doing this should make sure that it is safe. In this case, the heater produces its air by running air through a hot water radiator. This will never get hot enough to melt or damage the cabling.

very limited... but if you had the circuitry built for this already, then it was definitely worth it for the application. great stuff.

I like the simplicity. Why people keep building things in Altoids tins however, in particular involving electricity, I cannot understand :P
