Hi All,

Would anyone be able to tell me which way to connect a resistor for 5mm 12 VDC LED's.

I have 14 turnouts and I want to install the LED's for turnout direction. I will be using an old DC controller that has fixed 22 VDC and 18 VAC for the turnouts. Now apparently I can use 1000 ohm 1/4 watt resistors to reduce the voltage down to 12 VDC, but what I would like to know is:

Model animation—bringing models to life—adds enormously to the interest and enjoyment of any layout or individual model!  In the midst of the self-created kaos of preparing clinics for the 2015 NMRA convention, I snuck in the time to work on this animation of a DCC controlled UH-1H Iroquois helicopter, that I built for a friend. This video captured the project just after I competed all but the final details and decaling, just before it flew off my workbench.  All the sounds are generated by the model as you see it and hear it.

As I mentioned in my Building Simple Circuits thread, putting electronics together is an underappreciated part of model railroading. This note is another in my series of attempts to spread knowledge of this surprisingly simple skill. This will show how to work with an integrated circuit and an easy technique to go from a working breadboard to a permanent module.

(With apologies to Kermit the frog)

Thanks to advice from other members of this forum, I've figured out how I'll be installing the lights on my BVLC layout.  I've decided to build a shadow box, using pine timber for support and MDF board as the 'roof' of the layout.  It has to be self-contained, as my current house is a rental.
