Another use for Rare Earth Magnets
So, on my entertainment center project, I had paneled the cubby hole with cherry ply.
Prior to doing that, I had run a bit of drain pipe with some 90 degree elbows in to to run wires behind the wall, should I ever decide to mount the tv on the wall so that it is 'floating'.
Well, Today was that day, but I had a problem, In the last couple of years since I started the project, I had lost any measurements of where the hole should be. So how to find it? But I did have access to the hole on the bottom. I tried just poking a wire up the pipe and tapping, but that did not seem very accurate. Then an idea hit, why not put a rare earth magnet on the wire and poke it up and use another rare earth magnet on the other side?
Worked like a charm first time out.
On the left is a little hot glue on one of the magnets, and on the right is the other magnet sticking to the wall. Made it easy to use a roto zip to cut out the hole in the paneling to run the wire.
And hey, The tv is floating in mid air with no wires!
