Dear Mr. Tanner, Congratulations, this is really an amazing innovation. I am watching your videos very regularly since you started the channel, in fact, I am always looking forward to seeing the newest updates and caught counting the days until the next video will be uploaded. The universal board has a huge potential to really bring down costs in model railroad electronics through the economies of scale. I really hope to see more of this in the future and thank you very much for your contributions to the hobby. Kind regards H0Brickstudio

This is fascinating. I don't think I have seen anyone else do this, definitely not on KZbin. I look forward to seeing how your PCB stator design turns out and if it can be even more accurrate than the current setup.
@IoTT Ай бұрын
I agree, it is. I was kind of positively surprised how smooth the movement is, I expected more oscillations, particularly at stand still. The PCB stator is going to be very interesting. Right now I am looking into around 200 small coils along the circumference of the PCB. This relatively big distance from the center should give a nice torque, even the individual coils do not produce a lot of force. We will see.

It could offer both a visual indicator of the turntable location and rotation while also an input, via the encoder, to select the desired end position. Looking forward to seeing this one progress.

After watching this video I will avoid the No Ox ID. I already have a stuggle with pulling a set of coronation coaches (all brass), up a slight incline. The plan is to increase the weight of the A4 loco to increase traction, but the slip effect of the No Ox ID would have the reverse effect. I've just bought a CMX cleaning car and plan to use WD-40 contact cleaner which looks good on the chart for non polar. At least that will help. From my University days I remember that lubricant thickness is thinner and more effective with higher loads, so no matter how thin the application it will still act as a sliding mechanism. I guess the plan should be to clean the track and wheels on a routine basis - say once a month to keep on top of the track dirt. Plus do not use abrasives which scratch the surface and effectively increase the surface area for oxidation.
@IoTT Ай бұрын
Well, if you put some kind of grease on the track, it is to be expected that traction force, based on adhesion, is reduced. So I think you are on the right track with your conclusions. Of course an other alternative would be battery powered.
@hartenmellmann7033 Ай бұрын
Many great ideas! I always found it strange how complicated the setup and configuration is, in all those existing model railroad software. In my imagination driving a train through all the tracks should be sufficient to create a track model instead of hand-modeling each and every track and switch. Looking forward to see how this project goes on..
@IoTT Ай бұрын
I think you're right. I think the reason is that most software developers are kind of distracted by the many implementation details of individual railroad companies who are using different aspects and rulebooks. Once you look behind this, you find out that all is the same at the core. And it is possible to do a universal data model for it. I use the term security elements for the core data structure as this is what is used in ETCS (Sicherheitselemente), which I studied quite some to get an understanding of the fundamental train control concepts.
@alaingirard7524 Ай бұрын
Could you please explain the purpose of Security Elements #4 and #9, located between turnouts? Thank you.
@IoTT Ай бұрын
Train movements are typically going from one platform (eg SE#1) to the next (SE #5). However, tThe section(s) in-between need to be controlled as well, depending on the control system (CTC, ABS, APB). So for example, when using ABS, the status of SE#4 is used to prevent another train from entering the section. In an APB setting you would also need the #SE4 to manage the tumble down process, aling with the direction flag. In a CTC setup, you would set the direction flag and reservation flag, then use the occupancy release to free up the section. So, how you use it depends. But you need it because no section should remain uncontrolled or unmonitored territory. Hope that helps.

Does the board house have an option to just let us reorder you configuration? Would make life easy for those that would like five boards to play with. No connectors is a smart option, as they are easy to add and also it reduces the bulk for shipping.

I don't think that is a possibility, but using the design files from the Github, ordering is pretty straight forward, at least while all components are available. I quite often find that when reordering stuff after half a year or so, I have to make some parts changes. Usually not a big problem, but still requires some efforts.

I embedded IR photodiodes in between the tracks and have good lighting shining from above the layout. When the train rolls over the sensor it blocks the IR light from above and thus indicates the block is occupied. This is much simpler than using both an IR LED and sensor together.

That's cool, a simple solution if your use case allows for it. I would think the approach is somewhat challenging though if you have tunnels, covered hidden yards or if you do day/night cycle simulations.

I think that for G scale a GPS RTK system would work fine. You would need to set up a base station at a known position in your garden but then the system should have a precision of 1 cm. The system should fit the G scale rolling stock as well and you could use that to drive the trains. (There are projects for robot lawnmowers using such precision) Probably would not be too useful for smaller scales though
@IoTT 2 ай бұрын
Thanks for pointing this out. I see I picked the wrong picture from the SparkFun catalog, of course I had RTK in mind. Last time I looked into it, it was not down to 1cm accuracy yet, so that is progress. However, cost is somewhat prohibitive for hobby applications. A distance sensor, even with IMU, is only about 10% of that, and scalable, as explained in the video.

Security Element is probably a poor translation from the original German ETCS documents (Sicherheitselement). I learned later that the SE is similar to what is known in the US as plant. At the end it is an elementary data concept to model a track network, with each SE and leg equipped with block detection and entry signals to regulate access and speed.

Hi Hans, reciwved the purple hat and got it all hooked up an active. I have a question with the vstart/high settings. On esu decoders they have a minimum setting of 1, not 0 as your videos show. I then find the loco wont move on these lower settings. Is there a different approach with esu decoders?
@IoTT 2 ай бұрын
I am not very familiar with ESU decoders, but the vstart setting is a mandatory CV setting. More information is here: dccwiki.com/Vstart Of course the value you need to set so that the loco moves on speed step 1 depends on the drive train of the loco. Usually I recommend setting it to the lowest possible value so that PurpleHat measures the linear speed curve. If the loco does not move on the first 2 or 3 steps, this is not a problem. If it is more, the process will stop. If this is the case, you can set vstart to a higher value so you get some movements. It creates a slight non-linearity on the speed curve, but as long as it is not too much, it does not make a big difference on the final speed table. Hope that helps Hans

Very exciting, you are almost implementing GSM-R and ETCS in a way…? Would it be possible to use passive RFID tags in specific places, as a corrective to the distance counter? I was thinking that non-movable boundaries starting or ending a “set” route section could have a trackbed RFID tag. When read by the passing train and relayed to the central computer, several data-points can be quickly correlated (simplistic ‘sollwert-istwert’ scheme?). Passive tags can be read by a small onboard MCU & coil antenna, and the data string isn’t important as long as each tag is unique. Well, I’m just thinking out loud, and getting carried away… 😅
@IoTT 2 ай бұрын
The security element concept comes straight from the ETCS tech docs (I have referenced in several older videos). Of course I will not use GSM, but Wifi, probably mesh networking. I will talk more about these details in the next video. RFID is one of the options I consider for resetting the distance offset once in a while. For cost reasons I would prefer to have few readers in strategic locations, e.g. at the exit of a train station, and equip the rolling stock with tags. Another advantage would be that you could tag cars as well, which would allow for automatic calculation of the train length, and identify if a car uncouples from the train. There are other options to consider I will address in the next video.
@musiqtee 2 ай бұрын
@@IoTT Thank you for answering - and I’m sorry for pushing against already open doors… If I may, I imagined having the reader in the vehicle, and the RFID tags on the track - like passive balises?

I’m looking forward to learning from your project and solutions - again, thanks!
@IoTT 2 ай бұрын
Feeding back position information goes via Wifi, yes. Speed commands can come via Wifi, or via command station and DCC track. I intend to keep all possibilities open to make merging from one system to the other as painless as possible. No trackside wires is probably not possible, e.g. if you have electric turnouts and physical signals, unless everything is operated using batteries. But considerably less wiring for sure is a possibility.

Hello! My IBT-2 module, when no current, has 1.8V on L_IS and 2.2V on R_IS. When I put 10Ohm resistor - it increase to 2.3 and 2.7V. So command station shows 2-3Amp. I put capasitor 10nF but it doesn't change situation. Maybe it's bad module?
@IoTT 3 ай бұрын
I have seen some BTN chips that give an output current on IS as soon as voltage is applied. Is the 10 Ohm resistor your output load? The BTN chips I had with that problem at least had a linear error, so it is easily possible to compensate in the software by just deducting a constant value to the measured input. Are you using an external IBT-2 module with the 10k resistors to convert sensor current to voltage? I would try a different IBT-2 module and compare the results.

If you get the same results with the ASC724 I would check if there maybe is a problem with the GND potential that would lift the sensor voltage.

@IoTT 4 ай бұрын
In theory yes, there are a few points you need to verify though. First the IO pins for the DCC signal. The Tinkerface Shield feeds them to pins 2 and 3, but you can remove the jumpers and feed the input to the pins your motorshield needs. If the motorshield does not support driving the H Bridge from two inputs, you can use only one, but in this case you can not generate the cutout for RailCom, probably a minor problem. The second point to verify is that the motorshield can't exceed the maximum analog voltage when you do a short circuit test, it should have a zener diode protecting the current sensor pin.
