    I wonder if anybody has used the RS 20sec sound recorder in their trains or as a triggerable background sound for stations etc?
    The sound quality is surprisingly good , the $ 10.00 price includes the speaker , it doubles as the mike .

    It is listed as "9 Volt recording module"

    Gene,

    The guys at the hobby shop have an On30 set up with a mine as a focal point. As an afterthought they bought this little gadget from radio shack. Cut a square hole in the fascia about 8 inches below track level and made a mine shaft with an orecart and everything inside. When you push the button on the fascia (done by extending the leads from the switch in the original unit) lights come on in the tunnel and someone yells "thar she blows" or something like that. It is one of the neatest things I have seen. I can see many uses for this little gadget.

    Good luck!

    You record by speaking into the loudspeaker or holding a sound source next to it and push the button provided. It will save the recording even with the battery disconnected.

    My daughter has a stuffed dog that does the same thing. You push it's right ear to record something and then push it's left ear to play it back. It will stay in the memory as long as you don't record anything else over it.

    It would be cool if you could set it by a crossing and passing trains triggered the warning horn blasts.

    Someone one ScaleRailsOnline was using them, and selling them IIRC.

    IIRC the guys at the hobby shop said it was easy to just disconnect the button to record so they wouldnt accidently record over it. However they also said it would be just as easy if they ever wanted to change it back. It sounds like a versatile little unit! They also found a way to hook it up to the DCC track power because of the location on the layout did not warrant battery replacement. I do not remember how they would have done this one though.

    A bridge rectifier followed by a small 9V regulator would do it nicely. Including a bit of filtering , before and after the regulator.

    The start playing button could be replaced by a reed switch and actuated by a magnet under the engine or cars.
    This $10 device just begs to be used along the track route!!
    Can also be used in a car or tender, again actuated by a magnet/reed switch or dcc or radio remote.

    For those that have worked with reed switches, does a wave of the wand complete the circuit or must the wand stay in place for the circuit to be complete? Also what is the sensitivity of these reed switches? How close does the wand have to be to trip it? Lastly, will any magnet work? Thanks in advance, I might have an idea...

    1/2 " spacing should do it, depending on the magnet.And the momentary close should get the player going. The specs are on the radio shack site including the user manual. Look for " 9 Volt recording module" part number 276-1323A, no size given , according to picture, foot print is similar to that of a 9v battery and app 1/4 inches thick. So that is pretty small.
    I played with one a few years ago (when I used N gauge). Now with G scale , it will go anywhere.
