I only have a very basic understanding of the mechanics involved, mostly from a simplified introductory level youtube clip, Dr Quantum. So I was thinking the device was along the lines of an electron microscope or something.

Hey there! I have two questions regarding the Double Slit Experiment and the Wave Function Collapse. How effective does a measuring device have to be to cause a collapse? As in, say that every second the device has a 50% chance to turn off or on for one second, does the collapse still occur when the device has shutoff? Similarly, suppose an observer has been awake for a few days and perhaps even on a drug trip that is rendering them in and out of consciousness, is there a threshold in which the observation does not occur? Thank you for your time! <3 Phillip.
