This is for fun. How would you make a control system that causes the bathroom lights to flicker when when someone flushes the toilet?
I am thinking flow switch on the cold water supply to the tank piloting NO contacts on a relay. This relay feeds line voltage to a transformer (isolation type but tapped low) that causes an under voltage to the ballast at the fixture. (This of course assumes a fluorescent fixture). The under-driven ballast should now go in and out due to low voltage (think line flicker) if I am not mistaken. Even better if you have a magnetic and not electronic ballast. Flow switch opens again and lighting is normal.
Also, this is assuming that you love to change ballasts at your Moms house for a good laugh. Ideas? How to do it with incandescent fixtures?
