SMA37 Simple DCC Connections for Wide Decoder Adaptation

This article describes a small, simple interface to convert DCC signals allowing a wide variety of Arduinos, PICS, Raspberry Pi’s or other processors, to utilize a native DCC signal straight from your layout bus. With this you can build DCC decoders with the likes of an Arduino Mega2650 which has 67 input/output pins available for decoder use, or try using a Teensy 4.0 with 600MHz clock speeds.

AR 1 Part 2

OK, before I go back and purchase the other device previously suggested, I'm willing to listen to some suggestions to try and salvage what I have. The AR is supposed to control a Wye from my West Yard back to the main which curves around behind the yard returning Eastbound and thus, changing polarity.

The wiring drops from the main line and the Wye are set up correctly according to the instruction sheet and a drawing from the previous posting responses. Here is my problem:

Frog Juicer

Hello.
At a shortline station, I plan to mount a turntable and various tracks around it.
I want to use Frog Juicer to supply the frogs and turntable but am in doubt about where to connect them and how many to use.

I have attached track plans.

Speed matching

Although I've speed matched N scale locos for many years, I've always done it on locos that I've already programmed momentum into their decoders. However I'm not sure that is the best way. My question is - should speed matching be done with or without momentum programmed in?

TrainSpotter - Improved Design!

The TrainSpotter makes detection of locomotives or rolling stock easy and reliable. Place the sensor where its invisible light beam will reflect off the object of interest and you're done - no time-consuming or frustrating adjustments! Works in all lighting conditions. With discrete under-track installation, this low-profile sensor solves many of the challenges that plague other optical detector products.

The TrainSpotter now comes with a detachable 24" cable and simplified circuitry.

how much of a layout can one Uno based DCC++EX system power

Just wondering, how much of a layout can one Uno based DCC++EX system power?

My layout has two levels, each level has a 37' long BUSS. Plus the quarry style helix is 48" x 48" x 18".

When I get all the N scale locos DCC chipped and programmed. I will have  16 non-sound steam locomotives on the layout.

Starting a session, there will be a total of 6 locomotives on 4 staging tracks. And 10 on spurs around the main yard turntable.

New Bachrus Speedometer?

I have been keeping an eye out for the Bachrus Speedometer for years.  I was about to purchase one when they stopped making them.  I have had no luck finding one, at all.

Do you know where one can be purchased?

Lacking that, do you know how to make one?

Other possibilities: is anyone in the process of taking the Bachrus design and reproducing it?

Thanks!

Help with QSI Ver 9 Titan decoder

How do I turn off the momentum in a QSI Ver. 9 Titan decoder?

We operate with live loads and because we use this particular engine to switch one of the online coal tipples we need to be able to position the hopper car precisely under the coal chute. Hence the problem. 

We use a Digitrax UT1 throttle and use the toggle switch to control movement rather than constantly change speed with the knob. I have searched Google, The MRH search feature, read the QSI manual and adjusted the settings using JMRI and I haven't been able to turn off the momentum.

Gaps for a Reverse Loop & Wye

I'm looking at overlaying a wye and a reverse loop and I'm wondering about how to gap it.  Details in the first comment.
