    Post Weekend Update (27th Mar 2020)

    Please update us on the progress you have made on your MRR projects this week (commencing: 27th Mar 2020).

    This weekly thread is to post little snippets about your layout/project progress.
    This is not be a substitute for your layout build thread, but just a mini update on what you got done for the week.

    You can link from your layout build thread to your posts in this thread as a part of a more extensive post there, or visa-versa (post to your build thread and link to that post when contributing to this thread.

    Click on a post's #number (right-hand end of the post header) to get the URL to that particular post in your browsers address bar.
    Copy and paste this as needed.

    So, fellow nSn'ers, what have you been up to this week?

    I'm still working kits for the town I'm building. So many structures left to do, but making steady progress now. Here's the current build, RsLaser Kits, Zelda's B&B...

    I like the color. Something different!

    That's a great kit , I attached a kitchen to it. It's Kite's Grill and Bar , Manhattan Kansas on my layout.

    @JohnE

    I just bought that kit and am awaiting it's arrival - it looks real good mate and pretty straight forward to build. You've done a great job so far.
    @Janbouli

    I also like your addition to the kit ... gives me something to think about

    Great work on both builds.

    I was very much in doubt about which thread to post this, but I have received some IR detectors and LEDs in the mail.



    I am planning to install working signals on my future modules. I'm using the term 'working' lightly here, as there are some boundary conditions to other people's modules that I can't control and there will be simplifications, but I want some kind of internal signaling scheme that reflect the Danish signalling rules still being used today, called SR75. With the ongoing implementation of the European ERTMS signalling system all external signals will disappear, but on my modules they will certainly live on. I like signals.

    If you look at my track plan, the black markings on a track indicated some kind of signal, and to reset any one signal to stop I need a detector just behind it. Those are indicated with a yellow dot.
    There are several detectors on the market, and I think maybe the current sensors on one rail are most reliable, but they are really block detectors intended for long sections, and I have fairly short distances behind many of my signals in which to place a detector. There are also other aspects of this detection scheme that I don't like, but I don't have first hand experience with it, so I could be wrong. It's just a gut feeling.

    Instead I'm trying the IR detector way. If I can make a good reflective detector, I can place it between the rails practically anywhere, and anything passing over it will trigger a signal that can be passed on to the signal and any other listeners that may be interested. Also, they will be independent of the track voltage, which in FREMO context is important. In fact, as I write this, I remember it's a rule ... thou shalt not use the track voltage to power accessories! ... so that sort of settles the score.

    There's no magic to reflective IR detection and I've used it professionally in the past. One problem can be ambient light, and with a detector looking straight up from the module, fluorescent overhead light from e.g. a gym could trigger the detector if the overhead light contains an IR component. This is not a new problem and the detectors I've got are designed to counter this. It's called IS471FE and you simply connect an IR LED to the detector circuit. The IF471 then modulates the IR light of the LED at 38kHz and only reacts if it detects IR light modulated at 38 kHz. In theory, that should make it pretty much immune to ambient light.

    I was planning to start the construction of the modules now, but with the lockdown here extended through Easter and since I fully expect an additional extension at least through the end of April, I'm looking forward to playing around with this instead.

    @SteamPower4ever, please keep us updated on your progress. Will you be using an Arduino? JMRI?

    I use a similar shaped detector for in-line sensing, not reflective. I also have an Azatrax unit with detectors shaped and sized the same as your emitters in a reflective capacity and they work great even with bright fluorescent lighting overhead. They are small and would be easier to hide in the track than the square ones.

    Ah, yes. I remember Kite's in the Aggieville section of Manhattan from my days at K-State. Cold beer, good burgers, good times!

    Continuing the work on the Test Track/Interim Layout build. Have begun forming the terrain for the layout:

    The building is not prototypical of course , but I like to pick names of stores , bars and such that did exist in the town I am modeling . I do try to add at least one prototypical building in each town, it depends on if I can scratchbuild it or can find a kit that matches.

    For Manhattan Kansas I scratchbuilt AG Press , and the depot from Blair Line is almost exactly the same.

    Moose started that great train room and layout track cleansing of 2020!

    Moose could not see the wee labels of the ends of the locomotive and rolling stock boxes sitting way far away on the shelves above the layout, so Moose moving everything intro file boxes...

    But, more importantly, Moose clearing out mess from beneath layout so for to clean track. Managed to get a stinkin' expendable disease'el running on part of layout, checking for particularly naughty spots ... Yea, this is gonna take awhile...

    I'll keep you posted for sure.

    I came across the Azatrax unit, but decided to stay on my side of the pond - mainly for customs reasons. I hope to end up with a small reliable unit that I can just put anywhere I want ... which is what I'm aiming at right now.

    The on/off signal from the detectors will go to some aggregation device with Loconet interface. I haven't decided which type. There are a few to choose from. Haven't looked at Arduino much, but certainly an option.

    As for the software, I've been considering iTrain for a while, which brings me into the discussion about how to operate the entire setup. At meets I've seen several ways to control a station, and there's no doubt that simple toggle switches are the simplest way to do it. Anyone knows how to operate a lever. Arriving with a train at a larger station with unknown controls can be challenging, which of course is why at FREMO meets a station module is manned at all times during ops with someone who knows how to do it. That has presented me with a dilemma. Do I want to be tied to my modules or run trains? The jury is still out on that one, but I can feel I'm coming around.

    Again, the FREMO standard says that DCC is centralized and stations must have a booster, connected to the rest of the layout through Loconet. Switch control etc., however, is not standardized, so I can choose my own scheme.

    The signals will be from MGP, a Swedish brand that makes Danish signals in N scale. Their decoders are using Loconet, which is why I'm going for Loconet for the detectors also. The MGP decoders even have some built in intelligence to make the signals work without external software. I don't (yet) have first hand experience with this, though, but I've seen it used at meets.
    Also, keep in mind that the Loconet here is local and not connected to the overall FREMO Loconet as mentioned before.

    I'm still assembling the puzzle, but iTrain running on touch screens at either end of the yard is my idea right now. Maybe on Raspberry Pi with Linux?
    The command station for yard switch and signal control will be a Digikeijs DR5000, which I already have. It has all kinds of interfaces including Loconet.

    So, slowly making my way through a jungle of decisions, trying to arrive a something useful eventually
