Bartosz

I'm wondering what are the semantics of such block configuration. Is it: a) PU app reads back the value from motor B from the hub, then feeds the hub with the "set speed" command with value obtained b) the hub is instructed to maintain such "dependency" between the value produced from B and value feed to A Now, the advantage of b) would be that it wouldn't suffer from the BT latency, but I think it's unlikely it's implemented this way (I think it would hard thing to do?). Why am I mentioning this? Well, that's something I've been wondering after I saw your blocks, and it's something that would kinda explain why it wouldn't work with one hub and work with others...but really, this seems to be far fetched, correct me if I'm (terribly) wrong. :)

I'm using the https://www.lego.com/en-pl/product/simple-medium-linear-motor-45303 and it does the trick. Granted, I have some switches which are more "stiff", I tried to choose the ones that seemed to require less force (not to say it wouldn't work, haven't tried!).

I've been on that subject for some time. At first I wanted to make it cost effective so I ordered bunch of servos and wanted to hook some arduino. This failed, cause servo was too weak, and it was hard to fit it in without modifying any bricks (my goal was not to modify any switches). Then I made a break and noticed the powered up looks like really nice system (with latest update to powered up app). So I essentially followed this: https://www.flickr.com/photos/skaako/sets/72157629455967364/with/6933235178/ (Might want to use this: https://www.flickr.com/photos/skaako/sets/72157630024888612/). And it worked like a charm. Of course it's more expensive but...I don't really have time for hacking around hardware, modifying bricks. So if you're in that position, that might be best approach.

Hi, Am I missing something obvious, or it's really the case the documentation for powered up app is non-existant? I must say, I'm programmer so I really intuitively grasp almost all of that, but if I was a kid..hmm, would require really lots of toying to learn all those things. Or should I look into boost which might include some info on those programming blocks and their behaviour?

Wohoo, I've finished it... First of all, I had to connect 9V battery connector with PF connector. Fortunately andriend suggested simple solution: This resulted in quite a bit of connectors that needed to be stuffed in: In the end, it worked pretty well I think: Vid

Yup, I keep that option in back of my head, don't have that huge plans for rolling stock to justify amounts/shipping overseas...

That's what I'm waiting for. So annoyed that when bricklinking for train wheels you pay for three parts (wheel, enclosure and axle), and axle is quite pricey for a piece of metal... Curious how it's gonna look when they really introduce those changes .

Yeah, and knowing the kids are target for Lego, and considering how they lean towards smaller, 2 axle cars, it would make sense for it to not contain any bogie plates...

Well, but now you've just showed the case when AFOL would be indeed interested in buying that set for parts - at least till it shows in other sets.

Glad you've solved it! Would be a bummer to waste such circumstances (a free time without SO ;) ;) )

Maybe it's for opening the front.

Well, the "train folks" might not be their target. But if it doesn't sell well and they'll extrapolate it to trains then... Kind of catch-22. They say it's more likely for them to release train within some theme (as opposed to standalone) to have greater reach, but then - does it really work?

The train would make perfect sense for "haunted" series, but it also makes sense in the context of the AR app - after all, PUP allows it to be controlled with the mobile. Not sure how much can be crammed at this price tag though.

That's very interesting! Making custom solution was always on my mind, especially because I'm interested in something that can give smaller form-factor (even at a price of capablilties). Could you post more details? Photos of the controller+motor driver and how it's all assembled would be great, schematics (informal, just a writeup on used components) would be awesome :)

That's beautiful. I'm pretty sure everyone agree this deserves a thread on its own instead of being buried in here!

This, plus PUP (to not have to swap the green parts with gray IR receiver) looks like a sweet upgrade I need to treat myself for the next christmas :) Maybe I should also look in advance for some cool wagons...

That might be a non-answer but I found its quite efficient to just import the set as the palette into the Studio.io, and then build it from instructions:)

Oh my, that's the cleverness I'm missing in my attempts! But at least I know where to find people who know how to hack things! :)

Oh man, this year I tried to make the bareers raised by string, I've failed miserably (was using cheap servo). Later on I've found out one could just use motor with technic gear with clutch, but I haven't yet tried that out. Seems it works well for you - is it easy to set it up/ adjust it? If I'm right, you need to power up the motor for certain period of time, and rely on gear clutch to keep the movement within range? Also - the switches. That looks awesome, am I right it doesn't require any part modification?

Would be great to have this spaceship as depicted in that short movie. It fits me in terms of size (don't have the space for the (otherwise cool) spaceship from first movie, and the junior set is great, but too basic.

Why have I stumbled upon this just after ordering one of those. Well, will keep that in mind to snatch couple more during their lifecycle! :)

Right, but then let say you see that your latest creator train is now sold out, but you don't plan to release new one (for the reasons you've mentioned/not big enough sales etc ). You could just supply couple of more of the same and still sell it. Is that not enough?

Yeah, just yesterday my nephew (5y old) visited me to play with the trains, he had great time and the remote control was only a curiosity for him. Manual action is all what it was about. And for the adults at play - well, they can write the software on their own just fine, as we can see;)

Was thinking about something similar some time ago. No time/and only have basic skills to do that - my plan was to just power some locos with custom board and to try motorized switches. How do you plan on communicate between nano and rpi? And, most importantly, why nano (not saying it surprises me, just asking) ?

Well, first of all, if you plan to use motor how do you know when to stop it? After all, controlling motor is just setting the PWM (for speed) and it just gives you on/off capability.
