Control model railroad with Wifi and Mqtt

Almost all turnouts on the layout (around 50) is equipped with Lenz DCC-motors, and is controlled by the Mqtt-DCC that is shown in post nr 4. But for double crossings Lenz motors are not ideal, since the stroke/travel distance seems to be to short. Then it is better to use a servo and there is plenty of those to buy. They are often mounted under the layout but I took another approach. Using a small, linear servo it is possible to put it beside the turnout/csossing. That is an advantage if there ...

Control model railroad with Wifi and Mqtt

Made a schematic in Fritzing so that it is a little easier to understand. There is not many components on this small board but it can do a lot of things. This is for the four-led main signal (Signal A / S10) and the shunting signal (Signal B / S11) from the post above. And when it is mounted under the layout it looks like this Going to re-route some wiring later to tidy things up. To be continued…..

Control model railroad with Wifi and Mqtt

There is going to be a lot of signals on the layout and they will be controlled by the same type of Micro controller (Wemos D1 Mini). As we live in Sweden we try to make the layout as Swedish as possible, but there is not much Swedish things to buy in this scale. So we try to make things our self. I made a cuople of signals in Fusion 360 and printed them in the resin printer, Anycubic Photon. How the Swedish signals look like and work can be found here (in Swedish) http://www.jarnvag.net/banguid...

Control model railroad with Wifi and Mqtt

Now that we have a DCC++ Base Station Master that can generate DCC-signals to the track and the little device on top that can communicate via wifi and mqtt, we need something that can send mqtt-messages so we can get things working. I made a wireless remote control about a year ago that i have showed in another thread. It is basicelly a (little different) rc-transmitter that I use for cars and trucks, but it works fine for trains to. So we are going to use this until I get the time to build a ne...

3D-printed parts and accessories

My brother needed some furniture to a building so I checked on Thingiverse what I could find. Table and some chairs to the canteen and desk, chair and a couple of cabinets to the office. Found on several different places on Thingiverse and several different sizes, but it is easy to rescale.

Control model railroad with Wifi and Mqtt

Thank's for the link, Zoltan. My german is unfortunally not good enough to understand all that, but I think that it is something else then what we are building her. As I mentioned in post nr 2 I got a tip from a member at another forum that a Raspberry Pi could create a local network by itself. It sounds interesting so I thought I must try that. Ordered a new Raspberry Pi Zero W, it cost around €12 and an original case €6. You also need a micro SD-card and a power source. Thats all. It is really...

Control model railroad with Wifi and Mqtt

Interesting thing, Zoltan. Can you tell us more about that? Anyway, we are using DCC++ to get the DCC-signals out on the track. It's a cheap and clever open source project based on Arduino. I put some links here if you feel like diving in to it. DCC++ on trainboard DCC++ on Youtube We use an Arduino Uno as BaseStation Master to create DCC-signals. On top of that we put an Arduino Motorcontroller to get the power to the rail. And on top of that is a prototype board with a step down regulator and ...

Control model railroad with Wifi and Mqtt

Got some interesting information from a member at another forum. He said it is possible to use the Raspberry Pi for creating a local network, then you don't need another router. I have not tested that method but I might do it later. Raspberry Pi and Linux is new to me. Well, then there is two ways of fixing the wifi stuff

Control model railroad with Wifi and Mqtt

What is that? Well, Wifi communicates without wiring and Mqtt is the way things talk to each other. It is a smart, flexible and cheap way of controlling almost everything on a model railway. Most known in the popular home automation systems but it can of course be used anywhere. It can be connected to internet, but it can also be used in a closed, local network. A wireless router is needed to provide wifi and if there isn't any wifi where the railroad is, or if it not a smart idea to interfere w...

3D-printed parts and accessories

Ok, it took some time but here is the Simple Workbench V2. Working on V2 on the Rotating Workbench, will be finished in a month or three The Simple Workbench is very easy to build, yet very useful. Not every loco or wagon can be laid upside down on a soft material. The material is just 1 meter of M8 threaded rod cut in two halves, 0,5 meter each, and 8 M8 nuts. Plus, of course, some 3d-printed parts that I published on Thingiverse: Simple workbench And there is also a short video on Youtube: You...

3D-printed parts and accessories

Another long time project that I am working on, wifi-controlled railway. Just started and it will take a year or two. First thing, 3d-printed track plan connected to DCC++ master via wifi and mqtt (often used in IOT applications). The greatest benefit with this is that it is extremely cheap and flexible. And there is a lot less wiring. Track plan parts looks like this, 50x50mm. Can be combined in different ways The square holes are for rgb-led's, Neopixels. They are quite nice to work with, they...

SJ Locomotor Z49, 3D-printed model, a long story

Haven't done so much with this lately, been working on my remote control. Anyway, a small package has arrived from China with a new motor. I know, it's not a Faulhaber, but it only cost about €3. There is two major differences. The new one is 5 pole, the old one is 3 pole. I hope it will be a smoother ride. And the new one is 2,5 mm shorter, doesn't sound much but it will help me a lot. I have updated the cad-files to fit the new motor to the chassie and in a week or two there will be a new roll...

Just a little quick thing that actually works great. A bumper (prellbock) for Lenz track. Easy to print and assemble. Cost is almost nothing if you have a 3D-printer. Printed in white PLA so that is easier to see. Tight fit! Link to Youtube video: 3D-printed bumper Edit: Forgot to put a link to the files on Thingiverse: Bumper

3D-printed parts and accessories

Here is a couple of pics of the display in action. Startpicture, just for fun, not necessary. (It's the Z49I'm building, picture from CAD-program) Next page is "select locomotive". It can control 12 locos at the same time (if the driver can). My brother have 7 Lenz locos (1-7) and I have 2 (11-12). Let's choose V 160, then we get to "loco control". Here you can control speed, direction and function F0 - F8. It is also possible to have the functions in text, different for each loco i you like. I'...

3D-printed parts and accessories

Working on a wireless throttle control that is supposed to be ready for testing in a week or two. It is a prototype, like most things I seem to make The case is, of course, 3D-printed. Using DeWalt 10,8V battery Fits like a glove Lid with encoder And mounting holes for Nextion touch display I re-use code and hardware from my rc-models, so Arduino Nano communicates via nRF24L01 to a similar one, that is connected via RX/TX to a DCC++ base station. Should work. Hopefully. The plan is to migrate to...
