Blinging a CTB16 controller

I was looking at some old pictures of Mr. Chuck Smith's display control setup inside his home. He has a shelf with several solid state relays used to control his display. The relays are enclosed in a box with orange indicator lights on the outside, these lights show which channel is on. Since each light is connected to one channel, all of the lights dance when his show is playing.

I thought it looked cool to have all the lights blinking on and off during a show; so I thought, why not add indicator lights to a CTB16 controller?

I did some homework and some experimenting and found a way that would not interfere with the functions (dimming, shimmering, etc.) of the controller. I used 16 small red 3mm LEDs, 330ohm resistors and some jumper wire to make this come together. I had some problems getting full brightness out of the LED's without additional circuitry. But I think the LEDs do light sufficiently to view as you can see in the video.

As a troubleshooting aid, the indicators can serve to "see" if the control signal is going to the traics.

Now I have made a great LOR product even better. :P

It seems like the easiest way would be to just add a pannel mount 120v lamp in parallel with each output.

If you REALLY want it to run over RS-485, probably easier to just buy another controller - set the ID's to match your "outside" controllers - then plug in whatever you like for indicator lights.
