See rule 4.b.viii for details.

A single moveable pulley would probably work, though it would need a heavy counterweight (greater than 1 kg, even without accounting for inefficiency). It could be anchored to the high IMA pulley system (one of them triggering the other).

Wouldn't that still have an IMA of 1?

No, half the force comes from the free rope, the other half from the anchored rope. Example

I know very little about physics but all of the diagrams that look like that online say that the same set up has a IMA of 2

What you would actually want is something like this:

The easier thing would be a simple block and tackle type pulley (I think that's what it's called). One fixed pulley and one movable pulley give you an IMA of 0.5 so long as you pull down on the movable pulley.

Agreed, this would be much easier. An illustration, for those not familiar with pulleys:

Yeah that should be much more simple to construct, that looks right.

How would you go about activating the pulley?

I dropped a weight into a bucket attached to the moveable pulley, which made it go down.
