I had previously downloaded cartoon gun shots that I wanted to use for the Bugs & Yosemite Sam action car. I wanted these sounds to trigger when Sam emerged from the top of the car.
This MP3 Universal Sound Module provided an easy method to accomplish the desired effects.
I installed the sound board in a cattle car. The open slats provided a path for the sound. I mounted the sound board vertically so that the volume control could be accessed through the open door. The trigger was accomplished with a reed switch and a magnet connected to the fifth channel. There is a one wire tether from the sound car to the action car.
The use of MP3 sound files is a feature that makes makes changing or adding sounds very easy. I loaded Christmas music to checkout the use of the remote to select other sound tracks.
Future plans for other sound tracks are to add whistle and bell sounds. I have always wanted an electronic version of the Lionel air whistle to eliminate the motor growl and the relay and motor maintenance. Another sound track could contain a message "PLEASE DON'T TOUCH THE TRAINS" to be used at train shows.
A possible idea for a future add-on board could be a timer to automatically trigger the sound tracks. The times could be user set or even an option to randomly trigger the other tracks.
