A pair of boxcars on our club garden railroad contains 8 large LED matrix displays that scroll a message for visitors to see.

The message can be changed via Bluetooth from a cell phone, tablet or laptop.  You can also change such things as the brightness, scroll direction and scroll speed.

Hi

I have a return loop with a standard #6 fast track N scale turnout at each end .The turnouts have the usual gaps for a live frog.

How close to the turnouts can I put the reversing gaps to the turnouts. It would be convenient for me to put them between the diverging ends and the flextrack. Is this too close to the frogs for practical purposes ?

Using PSX-AR and NCE.

I have a Digitrax Evolution system and I am still learning all the ins and outs. I have it set up with JMRI to run the switches (I don't use it to run trains - I use the throttle for that). Yesterday, it seemed that all of my locos had become much more sensitive to the throttle than before and don't run as slowly as they did.

So I made this commitment to design a plug and play powered turntable and write a tutorial on it , something that can be built with (mostly) off the shelf parts, including an Arduino. (This isn't about the visible bits of the turntable, just the mechanism that turns it.) Any wiring will be restricted to standard things like switches and pushbuttons, with no circuit building required. The recent post by AnyRail shows one possible approach using a popular stepper motor with internal gearing.
