Mirror killing device
After seeing the crude dangerous device in the movie, I started thinking about how to design something better.
Lets assume two core facts that may or may not hold true in the movie universe:
1. The mirror is weak/defenseless until it gets uncovered the first time and starts to feed. If this is not true, then there would be no point in creating any device since the mirror *beep* you up when you get close. Maybe hiring a sniper and hope for an opening from long distance would be the best option in this case.
2. You want to record/demonstrate some of the things the mirror can do before killing it. If this point was not true and number one was, you could just smash it while covered and be done with it.
So considering these two facts, how would you go about designing a kill switch with timed and manual mirror destruction?
My idea below:
While the mirror is still covered, bolt a thick steel backplate to a steel frontal frame with the mirror between. Then weld the bolts so they cannot be opened.
In the backplate there will be a compartment with a mechanical timer set for say 24 hours. This will be the final unavoidable mirror kill timer. The entire back plate will be lined with fairly weak explosives, strong enough to break the wooden backside of the mirror and crush the glass but not much more.
Since there will not be needlessly strong explosives, you could hug the mirror and still have a chance to survive with some cuts and bruises. The front of the frame could also have protruded bars in front of the glass to stop anyone from getting too close.
The second timer, in case the mirror needs to die sooner:
Besides the mechanical timer, rig an electronic one connected to a cellphone.
The cellphone constantly pings a remote server operated by a human far from the mirror control area. If the server stops responding for a few minutes, the second timer blows the mirror up.
The person observing the mirror needs to leave the house every hour and go to a trailer nearby to make a video call to the server operator. At every call, the operator will decide if the mirror observer looks and sounds ok, and if the test can go on for another hour. If not, he will stop the server responses and mirror go boom.
When everything is set up, the mirror observer will cut away the front of the sheet covering the mirror, bring in poor Dog and start the action.
