I ordered it and it was to me in a couple days. I installed it in an evening and had it working when the local model railroad club came (see previous post).
The location of the talking detector west of Santa Barbara is on a stretch of single track about half way to Goleta. While I have compressed the distance there is an ideal stretch of single track on the layout that corresponds to thie actual location.
I followed the directions, installing the two detectors by removing a single tie and a section of the roadbed below to allow for the LED to pass under both rails. The circuit board could be mounted on one of the cross members at the end of the L-girder benchwork. In order to work the detector needs a speaker. It can drive a small 8-ohm speaker but also has an 1/8" connection for powered speakers like those used for computers. I had a set in an old electronic junk box so I pulled them out and measured in order to figure out how to install them nearby. I ended up building a small shelf with a front edge to hold them on and attaching the entire assembly to the thin wall under the track.
I followed the instructions and customized the announcements so they sounded like the real SP talking detectors I remember. Since SP has been gone since 1996 and my memory is getting worse, I turned to the internet and found a site with some recordings of SP talking detectors (http://www.trainweb.org/eastbayrails/sounds.html)
Once it was all set-up, I mounted the circuit board on the benchwork. I mounted it upside down so the controls were easy to access, in case I want to change the announcement or make changes in the volume.
Here is the completed installation of speakers and board.
All of this is hidden behind the fascia and the curtains.
Here is a video of a train passing the detector.
It was a lot of fun to install and very simple. It was a great diversion from getting the bugs out of my trackwork. Back to work.
