: I posted this down the page, but I thought some might miss it.
: All you would need is a variable speed drill,
: 2 limit switches, and here we go again...
: A double pole double throw center off switch.
: Set the drill on low, make sure the drill
: has an adjustment for this (red knob on handle).
: Mount drill at center of your boxed in monitor,
: wire up the forward and reverse on the drill,
: run wires to your switch and limit switches.
: Here is how it would work : Hit switch to forward,
: the power goes through the limit switch and when
: the monitor rotates and hits that limit switch,
: the drill will stop. Hit reverse to bring monitor
: back to it's orignal position. thats it , a very
: simple circuit...I will do this one day.
: And this is how I will do it.

This circuit came to mind about 10 years ago at
A school I was working in. In their gym they
manualy had to raise and lower the basketball
backboard when it was in/out use, They used a long
rod to crank the backboard up and down.
They ask if I could electrify it some how.
So with a little thinking I came up with this
circuit, by using a milwaukee angle drill with
an long extention bit mounted to the rafters.
The drill attached to the shaft that they used
with the crank it with. Using limit switches and
A motor control switch (foward, reverse and stop)
the stop switch was not needed, but just incase
it was wired in. After 10 years it still works
like a champ without one service call.
And yes I'm a nut too,
