Let there be sound!

I finished installing six small speakers around the layout. Five were installed on the fascia as you see above, and the sixth is embedded into a small river island on the Rock River.

These speakers will play sounds of the Rock River’s spillway with ambient birds,
I-280 road traffic, and random flange squeal from an ISE Arduino module. The spillway and bird sounds have a zen-like quality that puts me in a good mood.

  1. Very nice – and a really professional installation. Looking at this, I realize I have to up my game on my fascia…
    Cheers!

  2. Nicely done! Did you record the sound files yourself and then load them into the Arduino, or are they stock sounds?

    • So far I have downloaded sounds from YouTube and isolated the flange squeals I like and that have good variety. I’ve been encouraged by an audio engineer to make my own recordings by scraping metal together. Sounds intriguing, but I think I’ll stick with the actual prototype sounds. 🙂 I also include sounds of cars popping, and the groans we often hear trackside. This variety makes my approach unique.
