Vacuum Maker?

For my sleeping pad. It's a thin, around one inch one. I would like to have something to just suck out all the air when I'm done.

Get an ordinary bicycle pump, reverse the diaphragm, and it pumps out instead of in.

How?

The end where the rod slides into the cylinder unscrews.

Unscrew it.

There is a nut holding the diaphragm onto the end of the rod.

Unscrew it.

Turn the diaphragm over, then screw it all back together.

Erm... No... It's a rod... then it's a weird rubber thingy... a couple of o-rings, a white stick sticking up the center, and all the way at the bottom is another rubber thing. I think it's that one, but the disk is all the way at the bottom, and stuck I think...

It's the widest one at the non-handle end of the rod that needs turned around.

It may have two separate one-way valves in the body of the pump rather than one on the rod.

I bought a pump to blow up my air mattreses at a sporting/camping goods store. Cost about 10$.  Has a switch to make it a pump or a vacuum to do just what you want.

I like the bicycle idea also if you've got one handy.
