Due to profound admiration, engineering part 2
My wife looks in the bathroom mirror. Well thats ok. But its a retractable mirror at her height. Due to our differences in height and she never pushing back the mirror i always get a view of my privates when doing my thing.
It's not a pretty sight.
So i constructed an automatic retract mechanism made out of old parts.
1 cordless powerdrill
1 halloween electronic chuckle
5 mechanic relays.
1 electronic timer.
What it does: as soon as my wife pulls the mirror the annoying halloween chuckle goes off and the timer starts counting 120 seconds.
Any voltage drop on the chuckle causes it to chuckle, so while the mirror is extended anything electrical she uses in the bathroom sets off the increasingly annoying chuckle.
After 120 seconds the motor of the cordless drill spools a wire which retracts the mirror.
So after a couple of months of that i don't have to look at my privates anymore and my wife quits the bathroom much quicker.

picture 2, in the wall the electrical motor, the wire threads through the wall where the bathroom is. On the table the unequaled craftmenship in test setup.
picture 3, the rectact assembly. Note the compact design and easy access to the components.
due to overwhelming interest i added the original schematics of WifeEducator v 1.0 under the GPL.
