Silly sound effects - simply...

[Mike Deblis]

I'm having to build a quick "jeopardy" style fastest-finger-first
system, which I have done with a few d-type flip-flops & diodes.

As this is for a charity evening (we fund a school in sri lanka), I
thought I'd make it fun by having stupid noises when one of the
buttons is pressed - e.g. breaking glass, foghorn, bicycle bell etc.

But... I only have a couple of days left, so I was wondering if there
was a commodity chip (or even some example PIC & ROM code) for this
anywhere? I can find boring single noise chips, but I wanted something
a bit more fun...

Given time, I would probably have used a small PIC to randomly select
a noise from biggish prom, but even finding, recording and testing
such a system would take more time than I have left...

Ideas (very very quick & simple please) welcome!

Thanks

Mike

How about buying a number of those super-cheap voice recorder
key/pens/gizmos. Just wire to their respective play button contacts and mix
spur lines into an amp. Quick and easy to record to, even "on location".
I've seen them for a few pounds/dollars each.

PIC + DAC + flash interface (compact flash card etc) would be a better
solution. Write a little PC app to write wav files to the flash for each
sound. But given your timescales....

Idea 2: buy a toy or doorbell that plays one of N sounds. Hack the sound
selection. Limited choice of sounds but all-in-one and recording required.

Idea 3: use a PC as the controller. Buttons in on LPT1. Simple program to
scan inputs and play one of N wav files. PC is ridiculously big and
expensive to dedicate to this but if you have one that can be borrowed it
makes sense.

These gizmos use ISD family of ICs. They can be purchased from Digikey. Just
search on ISD... They are pretty simple to use, but I am not sure you can do
it in 2 days... Digikey might have some eval board however, which could save
you time.... Radio Shack might have these chips as well...

Find someone with any of the various electronic
keyboards, such as Yamaha or Casio; many of
these (and pretty much any above the very low
end) will include a wide range of sound effects in
their "voices" selections. Either borrow the keyboard
or tape what you want.
