Home Telephone Hack needed for Hard of Hearing
Hi there, My uncle has a fierce case of tinnitus, and sometimes he can't hear the telephone ringing. He can talk on the phone alright, the ringing just messes with the perceptions of sounds usually associated with home phones ringing.
So, he has a few phones hooked up around the house so he can try and hear the phone when it rings. its just a bunch of barely-functioning rotaries.
Have you ever seen that scene in bicentenial man where the clockmaker and his wife are talking in the kitchen when the hour comes and all the clocks start chiming. A cacophony of alarm. That is kind of like how it is at my uncle's when somone calls. I would like to set up a visual alarm system for when somone calls.
So, he has a few fairly loud rotary phones laying around. I'm sure he wouldn't mind if I took one apart along with one of his lamps. I just need to know where to screw, unscrew, solder, and smile.
