Signal Masts in JMRI 4.14, for beginners...

Here are all the notes and files from the Plano Train Show Clinic.

You need to have an internal sensor (IMCOMPORT) with the port in the value like COM10 or /dev/ttyUSB0, whatever Device Manager (or /dev/ttyUSBx) shows for the connected Arduino.

If you have Panels -> Script Output open, you will see the message: !!! Please add IMCOMPORT with the port in the value!!!

 The basic idea here is to use the Comment in the Signal Head field to define the position of the Pixel in the string commented to the Arduino, as well as the RGB colors to show for Clear, Approach and Stop (00:00FF00:BBAA00:FF0000). With all the Heads in the Table, run the python script and now you can update the colors in the Comment "live", keeping in mind that a message is only sent when a Head changes color.

We then put the Heads in Masts and use the Signal Mast Logic to do the magic. I like the original Panel Editor more and it works fine as long as you keep using Mast pairs, which requires you to create the "Stop" Masts at the end of the lines.


The files and code will be on TxNamib.com shortly.

Pi Pico, we smell competition in the land of the RRRduino! 

Pi Pico on an N-scale gondola Pi Pico, we smell competition in the land of the ‘duino!  Our very favorite low cost microcontroller system is seeing some fresh competition.  Everyone by now has heard about the Raspberry Pi, some fruity company in the United Kingdom, making single board computers!  They run Raspbian (or other flavors of Linux and are capable of some Windows versions) for as little money as $10 for the Pi Zero W.  The more popular Model 4, with 2 GB of RAM, retails for about $29.  Add a $5  micro SD card and you have a real computer with which you can surf the internet, write code and even program Arduinos.  It also runs our other favorite, JMRI.  Of course, plug it into a small or big screen television with an HDMI cable and you can even stream Netflix.  If you want a really cool computer built into a keyboard, also check out the brand new, Raspberry Pi 400 , you might just think you own a ZX Spectrum again. These are all “comp...

Layout sound on demand!

Here we go...all the sounds that you have collected over the years can now be heard from your railroad. In this article you will wire a sound playing module to a speaker and a Nano with 6 wires.   Imagine a button to announce the next train ready to leave, a light sensor noticing a stock car at the loading chute making some cattle noises, wheels squealing around a curve, or on my layout, elephants and lions in the wild! DFPlayer Mini pinout   So, save some sounds, (or “songs” called from here on), in MP3 format, onto a micro (u) SD card using your personal computer. Reading the documentation makes it a bit confusing, from: the order matters in which you drag the files to the uSD card, to: having 100 folders with each 255 sounds and commands calling which file in a folder?!? What I did was save my sound files as 001.mp3, 002.mp3 and so forth in the root folder of the drive, and had no trouble getting them to play. Remember to properly “Eject” the card using your operati...
