Could it possible that the light from the detector or the electric current inside of it is affecting the energy state of the particle/wave, changing it's total energy/momentum and thus can cause a difference in outcome? I believe the same could be said about the case of human observation affecting the outcome. Observing the experiment causes some of the light/energy to escape into the eye of the observer, thus changing the energy total and behavior of the particle/wave. On that note, I like to imagine that light goes into one eye (observing the world) and antilight/light waves made up of dark matter goes out the other (affecting the world).
I have many neat theories about stuff like this, well, pretty much everything. I have constructed somewhat of a holistic world view.
