guess it's time

Some time ago I installed a waste heat ejector on my system. It is teh awsome to have all that heat out of the room. Without it, recirculating waste heat raises the computer tempterature by several degrees as it keeps warming your space and being reingested.

I bought a normal ceiling box fan and a motor speed control switch (looks ike a dimmer switch). I put the fan on the floor under the desk on it's side and plenemed the opening to the back of my computer with cardboard and duct tape.

Then the output of the fan box is a 4in hose that goes to a 4 in duct pipe up through a book case and into the ceiling. It's compeltely invisible unless you realy look for it (Being surrounded by books).

Running the motor at half speed gently sucks the heat quietly away and up into the ceiling and my office is no longer a sauna on warm summer days The computer runs about 5C cooler inthe summer. In the winter I open the side of the plenem (hinged so I can get at the cabples and whatnot) and let the warm air blow under the desk like normal to help with the heating bill

It is not often that I confess befuddlement. I keep looking at the picture, wondering "Why?". Reel in the dog? The laundry? No. The function must have something to do with this...

well this a too much of a hint, but still 1 rep if you figure out what it hoists.

( the bottom arrow you pointed at where actually a few spokes i had forgotten to take out)

getting warm. Think like this:

24V dc 5 amp motor, fed 50v dc 10 amp

its being overfed electricity?

it puts out .5 kw, or about half a horsepower. 1 horsepower is defined as pulling a weight of 75kg 1 meter up.

What would weigh enough you'd need that force, geared down a large ratio, in a winch on an attic?

A woman in a camping fridge, a retired rapper in a camping fridge...

You crack me up.

The folding stairs! The attic folding stairs lower and rise by pushing a button.
However you shouldn't stand beneath them when lowering they tend the lower at a rather higher speed then they rise :)
