Otaku, have you found any cheap MP3 players that include a random or shuffle function ? Wondering if you had one with a shuffle or random switch that maybe it could work ? As long as you could have it start playing from the depression of the play button from the off mode... ???It's not a DIY, but the price is good:

You could use a 4017 IC to control the players, but it would need to know which output was last active, in order to start on the next pin. There should be a way to do that - I'll look into it.
I was gonna suggest that, too, Doc, but I think he wants the sound to be triggered rather than a repeating loop. The CD player idea is a good one - just need to figure out how to get it to play the next track in the sequence. Shouldn't be too difficult to do (famous last words...).Why not just use a cheap MP3 player? You could put a pause in between routines using Audacity which is free. Or find a cheap CD player (do they still make them? lol!) one that plays pre programmed tracks.

I had an old discman last year for my Boris. I soldered a wire from a relay into the play button. It worked great. The only downfall using the CD player was the delay. I was using 1 track, but the player had a random switch, so rightfully, I could have recorded multiple tracks. The only thing then would have been to stop the player after the prop triggers before it moves onto the next track....![]()
