Ringing a magneto phone bell with a motor driver, but volume too low

My original intention was to create a sort of presence detector for an outside door. With two PIR detectors it could determine if someone from outside was entering the room, but would be unaffected by activity in the room itself, and then, if detected, sound a standard GPO type ring.

Nice! Great idea. Subtle, but unmistakable.

For example if you dial "popcorn" (are you old enough to remember this?) they hear an ad and the current time.

Yeah, I had totally forgotten that was actually a service one could dial!

@SteveMann

The game controller can send clues or hints to the phone (all prerecorded). The phone rings, and when they pick it up they hear the recording with a clue or hint.

That sounds great! Very clever - I like how you can then choose what is played, depending on the situation. Mine would just be the single file played, but this is giving me ideas Thanks for sharing!
