While this doesn't have any classic content, it may be interesting
to some.
I'm working on modifying a Heath/Zenith wireless doorbell to play
a sound effect other than the really bad "ding dong" or "Westminster"
version of the same. The new sound effect will be the Cloister bell
from the Doctor Who series.
Patching into the doorbell circuitry to detect when it is playing
its builtin sample is relatively easy. Coming up with a simple method
of outputting my new sample is a bit trickier. As I recall, there were
some specialized ICs out a few years back which would do just this
sort of thing. I've also considered connecting a basic mp3 player.
Other suggestions?
Thanks and happy new year to all!
