    Imagine Your:
    • Town with the people talking, baby crying and children at play.
    • Depot with train anouncements and the conductor calling out 'All Aboarrrrrrrrrrrd!'.
    • Engineer talking to the tower and other railroad radio message.
    • Factory with noises of the machinery
    • Water tower and the sound of the steam train getting filled.
    • Farm with sounds of livestock.
    • Brook, river or waterfall with sounds.
    • Sound of a train as it rubles by a focal point or pulls into a station.
    I did it!
    How To:
    1. Record or Download the sounds to your bluetooth enabled smart phone
    2. Find a suitable app to read them
    3. Link your smart phone to the speakers
    For multiple locations Either:
    • Multiple phones operated by one person
    • One phone with several sounds on it
    Downside:
    • For continuous sound you need one phone and set of speakers for each location
    • Cost: $10 to $30 per location
    • Family would have to contribute their phones now and then. My family has 5 active phones and 3 older phones which are being tested.
    Currently in 'test' mode awaiting more cheap speakers but it worked great with my bluetooth ear buds.

    Long Term Idea
    Recordable sound chip with:
    • Battery opperated speakers
    • Optional bluetooth control
    Anyone able to make something like that cheap?

    Feedback invited.
    Feel free to be serious
    Constructively but openly

    critical
    Humorous, but be nice.

    I saved an old Phillips MP3 player and a small iHome speaker to put in a building. Access to player will take a little creativity.

    I would like the sounds of my steamers if it could be isolated from those that don't want to.

    I'm thinking of period correct music for my "someday" passenger train. (~1940 - 1963) I have a 4-6-0 to pull it, still need 4-6 cars and a R.R. Maybe MP3 and some speakers, it's kind of a future thing but at least I have a list.

    There are several modules available that you can download sounds to, some you save the sounds on an SD card and some you download through USB. . I don't know of any off hand that have bluetooth control, but they do have the ability to wire in button control, which would be easier anyway. Here are a few:

    Some of them have multiple inputs that will trigger individual sounds, so you could have triggers on the layout activate sounds (i.e. crossing gate sound when a train passes a crossing, or a button to trigger water filling sound, etc.). With a little additional work many can be interfaced with an Arduino to give even more control over the sounds (such as randomly triggered sounds).
