I expect to design the control around LCC: Layout Command & Control.
Any opinions on this?
Any suggested alternatives?
My first project will be prototype searchlight signals, using UP aspects of the 40's & 50's.
I have obtained 3 watt hi-power RGB LEDs and control ICs for the search lights.
Expecting to use PWM from an Arduino board to light them up, change color, accept LCC commands, etc.
After this I expect to tackle LCC controllable switches.
I am using LGB switches, but am not impressed with the motor units they sell.
Will experiment with servos and feedback micro-switches, again LCC connected.
Any ideas/experiences in this area would be appreciated.
I've finished a prototype of a searchlight using a 3 watt high power RGB LED.
This is the light only, no proper tower yet.
The above are red, yellow and green.
The colors look much better to the naked eye, something about photographing them shifts the color spectrum.
I can clearly differentiate the 3 from 200', so it does what I need.
And I think they will be much brighter when refined, I didn't have the proper current limiting resistor on hand.
This is using about 120mA of forward current, the final version will be more like 350mA.
Here's a video of it displaying the Union Pacific aspect rules of 1972: UP rules
Again, I apologize for the quality of the LED colors.
The yellow looks white, but to the naked eye it is quite yellow.
I did a little research, and it appears to be a big effort to photograph RGB LEDs as their color spectrum confuses modern CCD technology
