I would like to build a control panel for my conventional O gauge tinplate layout. I have been searching for suggestions on how to build the panel and think I found what I need for construction materials.
I would like the panel to display whether power blocks are turned on using an LED light or one color LED for power on and another color for power off. I have been reading about bi-color LEDs but many of the threads are several years old. I also need to include toggle switches on the panel to turn the power to the blocks on and off. I also probably need some toggle switches for street lights and building lights.
I have 11 O-22 switches in my layout and would like to have green/red LEDs to indicate which leg of each switch is open. Again, I am considering using red/green bi-color LEDs for each leg of each switch. I am considering using 3mm for this and 5mm size for the power blocks.
I have several questions:
- Do you know of recent posts which would help me with this project?
- Should I use a different color pair for the switch blocks?
- Do you have any specific suggestions for sources for the LEDs and the toggle switches? Resistor sizes for the LEDs?
- How best to wire these lights to indicate the direction of the O-22 switches?
- Has someone come up with a better way of accomplishing the tasks for my control panel?
- Did I post this in the proper forum or would the O gauge forum have been better?
Any suggestions and input will be appreciated.
