Ich nutze SG90 Micro Servos die ich in einem Lego Gehäuse verbaue um die Weichen zu stellen.
Das Problem mit den “durchdrehenden” Servos kenne ich.
Dieses tritt sowohl bei v0.3 Servo Controllern als auch beim Layout Controller mit PCA9685 auf.
Tatsächlich besser wird das Verhalten, je genauer man die Servos justiert.
Ich wollte noch versuchen, nach der Justierung aller Servos an einem Controller, dessen Min- und Max-Werte für die Servos in IDE so klein wie möglich zu definieren.
Ich werde berichten, ob das Verhalten dann besser wird.

Hallo Matthias,

vielen Dank nochmal für die ausführliche Anleitung!
Hat mich direkt dazu verleitet größer zu denken und ein paar Sachen zu bestellen.
Das Display werde ich nicht nachbauen. Aber die Website ist für mich eine klasse Anwendung!!

[Max]

Ich finde die Lösung wirklich sehr schick!

Wie hast dus realisiert?

[Max]

Ich hatte in Matzes Videos den Batteriestatus nativ mal in Rocrail gesehen. Allerdings war dies dann ein Zug Controller..

[Max]

Hallo Matthias!
Sehr schöner Bericht und tolle individuelle Lösungen die du hier zeigst!
Besonders cool, die “CurvedSlopes” zum verstecken der Reed Sensoren.
Ich sehe schon, bei der Anzahl die man davon benötigt werden die Preise unweigerlich steigen 🙂

[Max]

A short “search the issue”.

The layout:

The Problem:
I”ve had a problem with another ESP8266. The motor on the motor driver port B went on 100% as soon as the loco was powered on.
Replacing the l9110 did not resolve the issue.
So I decided to completely solder a new one.
Nevertheless the problem was the same.
A deeper look into the PU config could not detect anything.
Then I had a closer look on the PCB board again and.. B1A was not connected at all!

Please test your boards prior to operation. 🙂

There it is: Switch_case Instruction.

[Max]

You can connect it directly.
But as you probably want to connect several switch motors too, place a small PCB board between it to share VIN and GND.

You can use a PCA9685 to extend the ESP ports and VIN and GND too.
But the v3 case isn’t designed for the use of the PCA9685 extender.

Hi Matthias,

I’ve created a new MOC on rebrickable.com. But the admins need to approve the MOC first.
In the mean time, please find some details here:

– wanted list: Switch_case_v3_list
– batterie case: 4 AA Case

And some pictures of the case:

[Max]

For the moment, the last and most challenging loco I’ve built so far.
There is so less space that I was forced to omit the PCB Board end even rewire the motor.
Fragile but it fits and does work!!

By the way, it was the very first Lego loco I’ve got more than 25 years ago.
The original motor still works fine and holds the personal record in pulling the most waggons.
But with the new Mattzo features it reaches a complete whole new level 🙂

[Max]

Very nice casing, thank you very much for sharing this!

[Max]

Schau mal hier: Schnellzug-grau-blau-BlueBrixx-Special

Hallo Zoltan!
Aus eigener Erfahrung kann die Sammlung natürlich via Kleinanzeigen erweitert werden. Um auf Nummer sicher zu gehen, dann halt persönlich abholen.
Dennoch kommt es vor, dass einzelne Teile fehlen. Hier hilft bricklink.com weiter.

Weiter empfehlen kann ich als Klemmbaustein-Alternative -> Bluebrixx
100% kompatibel zum Marktführer, absolut legal (weil keine Clone) und sehr individuell.

MOCs von rebrickable.com sind als letzter Tipp auf jeden Fall einen Blick wert. Vorllem da diese im Gegensatz zu Bricklink nicht auf das Teile-Sortiment von Lego begrenzt sind.

[Max]

Hallo Piet,

ohne deine Schaltung gesehen zu haben, ist es schwer zu sagen was du ggf. übersehen haben könntest.

Wenn du Klemmen nutzen möchtest, kannst du jeweils VIN und GND von der Quelle zu den Verbrauchern (ESP und Motor Kontroller) zusammen fassen.
Darüber hinaus kannst du, vorausgesetzt du schaltest Wiederstände dazwischen, auch die LEDs an die Klemme GND anschließen.

Wie man das zusammenfassen kann, kann man vielleicht auch ganz gut auf der von mir gelöteten Version eines MTC4PF sehen.

Hi Leo!
To be honest, I did not. 😉
I’ve read Source and decided to give it a try on the breedboard first.
With the 8.4V Lipo it does work well.

[Max]

Hey Community!
I’ve managed to finish the third and yet the best variant of a MTC4PF based on a D1 mini.
It is 60mm in lengh, 25mm in width and 15mm in height.

Yet the best combination and I would recommend the solution for locos like Lego 3677 or any other model with similar mount of space.

Here some pictures.

Greetings Max

[Max]

Although I do like the flexibility of your protoshield integration, it’s very unusual to need so much port isn’t it 🙂

[Max]

Nice project Zoltan!!

The topic you’re looking for could be the mattzobricks-integration topic.

[Max]

Dear all,
I’m really proud to reveal the latest and finished MTC4PF build of a 3677 loco.
Due to the required space for the electronic components I’ve redesigned the front from scratch.
Powered from two motors and with an over all weight of around 460g, she has enough torque to pull at least some wagons 🙂
Enough sad, please find the pictures below.

Greetings Max

rebrickable.com – MOC-68258

Studio Prebuild.

Two batteries are narrow but possible.

The loco with its friend the MattzoSwitchController.

More to come.

Good morning Lego Automation Enthusiasts!

I’ve managed to solder a much improved version of a MTC4PF. It features a on/of button, battery and LED connector and is due to less wireing less vulnerable to pysical movement.

It is 55mm in lengh, 25mm in width and 20mm in height.

Altough very compact the height can be improved if a L9110 motor controller without pre soldered pins is used.

But enough sad, have a look 🙂

Hey Yevgen,
some double sided tape within the lego casing. If you adjust the servo it works very well.

[Max]

Hey Piet, I do face the same behavior of the SwitchController.
Try to use only one servo at a controller. Does the problem persist?

[Max]

Hast dus in Rocrail mal unter “deine Lok -> Eigenschaften -> Geschwindigkeit” versucht?

[Max]

Hey Douwepen, what a good tip, thank you!
Over night I had a idea how to get rid of the cableing to the motor shild.

Can’t wait to start the next soldering session 🙂

[Max]

Based on the latest build I soldered a MTC4PF. Its my firt conroller and it does work. Nevertheless I am not completely satisfied due to the fact that is does not fit in the front of my Emerald Night 😉

But here are some shots I’ve taken:

The wireing diagram.

As everything, at the end you improve and next time you can do it a bit better 🙂

Cheers!
