How about a little solenoid? You could then use wire of arbitrary

all hard to make one if you have a lathe.

The problem with a lot of solenoids is that they shake the camera

Yeah. Put solenoid on short cable release, so the reaction (jerk) of
the solenoid's plunger accel/decel is isolated from the camera.

It is certainly possible to slow down a solenoid so it doesn't jerk,
but that might feel unresponsive to some users.
