It ain't done yet!

Meanwhile I went hunting for some battery boxes for my lighting.....  having come up empty at the craft shop and the hardware, I went to the toy aisle at Dollar General...


A few swipes of the Dremel and I'll have handy battery boxes to juice the accessories!

Now that's some creative cheapskate modeling right there.

Plus I got two for the price of one!  I can put a separate switch on each module!

But... what about those poor radios??

Poor is the operative word.  For $6 I got two battery harnesses, two on/off switches, and two momentary contact switches.  The rest is surplus.  The plastic can be recycled, and the circuit boards and speaker/mics can go into the junk bin for some as-yet-to-be-determined fate.
Perhaps I could wire them to a 9v wall wart (of which I have dozens) and make a clever intercom between some future layout control point and a dispatcher's office...

Maybe I missed it, but is there a reason why you didn't just hack into the DCC bus and power the lights without the complexity and cost of these battery packs?

Well, TTrak is wired for DC control in its basic design, but can be easily adapted to DCC depending on the controls available at the particular set up arrangement.  As such, there's no guarantee that the track power will be constant or variable.  While some TTrak clubs have an accessory bus, many do not, and there isn't a particular standard since not everyone would use it.  As such, I was encouraged to install a simple battery pack to power my lights, and that seemed like the simplest solution.

When I have the modules clicked in to my Retro layout, track power will be DC, so it makes sense for me to use a separate power supply for the lighting.  My plan is to install a DPDT switch that lets me alternate between the batteries when I travel with the display, and a 9v wall wart when it's installed at home.

Can you make it operate like the pilot controlled runway lighting at some small airports, which is activated by pulsing the microphone switch several times when set to a certain radio frequency?
