I find the indicator clicker on our 2009 Ford Galaxy annoyingly
quiet - above about 40 you can't hear it, and so I can drive for
ages before I notice the indicator light on the dash.

That's the problem I have too. It has an early electronic flasher
unit which is nowhere as loud as the old bi-metal strip type.
But if I had an electronically generated noise via an amp and
speaker, would be easy enough to make it as loud as I want.
Even to make it louder as background noise goes up.

Wouldn't be hard to do with an arduino or even a pi.

Could do but niether are really amplifiers,

Don't need an amplifier when you are using a digital device
to produce some tones by driving a speaker or piezo directly.

might prove to be more expensive too

Nope, you don't need a damned thing, just
the digital device and the speaker/piezo.

Ideal for having it auto adjust the sound level to the
background noise and do whatever you decided to
do when more than one sound is required at once.

and quite a bit of faffing about.

Lot more with a separate say micro tape deck for each
sound, particularly with varying the intensity with the
background noise and with more than one going off
at a time etc.

This might be OK

Doesn't have anything like the flexibility of an arduino
or a pi with getting exactly the sound you want for each.
A device that can play any mp3 you can find that you
like the sound of leave that for dead flexibility wise.

Corse given that Dave isnt into programming, it might
be better for him, but that's a separate issue entirely.

Or to annoy someone, they left that use off the list
