I got mine off of ittproducts.com.
Mr. B's post brought to mind another cheap possibility, those recordable greeting cards.
I was out drinking with some friends tonight. One had a RaspberryPi, which is a small Linux computer that costs about $35. It has HDMI 1080p video out, but audio, too, of course, so could serve up all kinds of sound. Since one of the model railroad sound outfits charges you $35 per sound, the RPi sounds pretty costs effective if you don't mind setting up a Linux box.

I forget where I got them, but I found a silly box online that has a button to push to record and another to play back. I bought 5 of them for $2 each. I wanted to put one at each end of my subway station and have them play a short sound clip of flange squeal as the train passed by. I couldn't get the trigger to work right, but for a manual pushbutton it would work just fine. The sound is pretty low quality, but for flange squeal it was passable.

Google it. I will let you do it. Hardly anything is Ungoogleable.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
It is already out there! I do not have at hand the electronics guy who makes these, but hopefully someone finds his address before I do as he advertises in most of the model RR mags. His simple controller has 10 buttons that are all programable to speakers. You can program fairly long phrases, sounds off his site or anything audio including a microphone to do the audio voice overs oneself-very fairly priced as I remember. All the conductors, birds, rivers, planes and dance halls one can imagine---have fun. joeldee
I am working on an electronics project and I am looking for some little sound-chip and speakers that I can put in a train station (for example) so I can trigger sounds.The triggering mechanism is what I'm working on, so I'm hoping to find something that's just button activated (or easily modified) for me to control.The specifics of the sound aren't too important ("All Aboard" or a bell would be great).Ideally this would run off of HO track power.Does anyone have any ideas where I might find something like this?
