Arduino for Lego Trains #9: Automatic Decoupler
Вставка
- Опубліковано 4 гру 2015
- Seperate your wagons from your locomotive using this awesome Arduino-powered decoupler!
Using a single motor and some infra-red sensors, this clever construction of gears, axles and plates can block one side of the track, preventing individual rolling stock from moving forward. From there, just power your train forward to uncouple your wagons!
This tutorial incorporates the decoupler into a siding, allowing you to uncouple wagons, switch points, then retrieve other wagons before continuing on your journey. All the code you need for your Arduino is provided, including a full explanation of how the decoupler is build and configured.
Contains vintage 9V Lego train sets 4565, 4544, 4552, 2126, 4536, and 4537. - Навчання та стиль
Lego released an automatic decoupling unit 40 years ago for the 12v train system - set 7862
and it is a lovely set
Brilliant. Would love one on our layouts!
Very brutal, but absolutly awesome 👍
ALT, Today you won the internet. Amazing!!!
Could this code be modified to pull away slower when decoupling? It seems incredibly rough.
Man, this makes me wish I could find a lot of 9V track and an arduino for decent prices.
Or, for that matter, space to put it.
Another great tutorial as always!
The tracks are not 9v
Just cut a power functions cable and wrier it to the ardinuo
2:40 An interesting design, but IMHO has a big drawback: since the slider is upside down, it only works on a smooth surface like the desk in the video. But it would not work if the track is built on a carpet, as is often the case. So it would be better to have a design with plates on the bottom, then tiles (all upside up, not down), then the slide consisting of a plate and the gear rack on top.
That decoupling looks pretty aggressive, Does the train itself have a throttle threshold that can be manipulated so at it's lowest speed it uses only the required amount of force to decouple?
Awesome tutorial as always! ;)
+Multidomar Thanks!
+Arduino Lego Trains
is a witch , uses black magic to make these works of lego

oh no! You have discovered my dark secret!
Awesome Tutorial!
5:17-5:21 WE ALL GOT ROASTED BY HIM
Man, this is real engineering! Do you have any other UA-cam accounts?
Just my professional voiceover samples, which is far too boring to link here!
a magnet sensor could be used not only to determine the location of the gap between two cars, but with two magnet sensors, you could measure each car's length and speed.
Really nice project!
One question please: In 0:13 the switch is moving, but I can't see any motor or another mechanism that moves it.
I'm really looking for a easy way to control train switches by Arduino, and would be glad to learn this method.

Part 3 ("Motorized Track Switches") of this video series shows a nice motorized gearbox to control a switch. It uses an old 9V Technic motor and some Technic parts, all genuine Lego parts: ua-cam.com/video/h-5FmGfYzRs/v-deo.html
Hope this helps!
3:14 Guides could be required for keeping the tab that pushes up the decouple flap in place. Other than that, decoupling my trains has never looked easier.
Why was the decoupler not hitting the front bogie of the freight car with the 2 blue cement mixers ?
+Paladonius In the code I used the map function to reduce the sensitivity of the IR sensors. Despite this, the sensors occassionally register black lego as a 'gap', because it doesn't reflect IR light very well. If you look at these wagons, there's a black ladder on the side - the arduino thinks that the gap is there, and reacts accordingly.
if you don't wana hear about the technical code then skip to 8:42
this is awesome don't get me wrong but wouldn't electro-mags be easier?
How do you mean?
wouldn't electro magnets be easier than your method
electromagnets where? between the wagons? That would mean replacing every single magnet (the standard lego connection) on every locomotive and wagon on the track, and adding a second power system to keep them connected when the train is not in motion (because when the train stops, there's 0volts in the system).
So sure, it would make disconnection easier, but it would make keeping the wagons connected a lot more complicated.
how to build ?
The profile page of this channel offers a link to a website where you can find written tutorials to these videos. They also contain building instructions in multiple colors, very useful.
what app is that?.
What do you mean? This is all programmed in the Arduino IDE.
Ok, i didnt understand at first, btw awesome tutorials they are so cool, i wish i could make the things you make but i dont have things needed 😕
9:50 Don't drink and train.
90th!!
+Stubbsy congratulations!
