You don't need the official train base but it makes things much more easy. You can look at the Emerald Night building instructions if you want to have an example for a gearpack.

Thanks :) There are 3 problems with testing a 9V motor. 1) I have no 9V motor (nor straight 9V track) 2) They should not run more than 10 minutes because they might "overheat" (at least that's what "zusammengebaut" wrote) 3) Lego emphasized that they tested the currently available wheels and tracks, not older ones. 1) The problem is that the wheels might act differently with different weights. So I tried to keep it as realistic as possible 2) I think that they made sure that the voltage is about the same for both batteries, but they have given no data on that, yes 3) I removed the flex track because it moved way too much. It might have had impacts on the results based on how it currently layed - and that changed every round.

Hey, maybe you remember my comparison of the new train wheels (I think that my video was the first one to do that). Now that lego actually made an "official" comparison, I HAD to check their claims - especially since their result is basically the opposite. My test setup is basically the same (tho a different track layout with more straight track). A train (this time an actual one and not just cars with weights) drove in a circle and got timed by an EV3. After 10 minutes I switched the wheels and the battery and did the same again. Here are my results: (round times, less = better) This confirms the results by lego but stands in contrast to my first test. There have been a few problems with this test so I decided to do another one - but to remove a few of the error sources: I replaced all the flex track with normal track, measured the voltage of the batteries (they had a difference of 0.02V in the 2nd test), fixed the track on the ground and made a 25 minutes test since 10 minutes wasn't enough in my opinion (but I won't do a longer test - I don't want problems with my neighbours ;) ). Here are my results for the second test: (round times, less = better) Here are my conclusions: 1. The batteries have an extremly high impact on the results (and aren't relieable enough for so small differences) 2. Both wheels performed about equally - at least with the accuracy of this test, the difference in initial value can be caused by the batteries.

I think that they'll release it as an add-on to the current hubs anyways (as replacement for the battery holder). That way the battery doesn't have to contain the bluetooth hardware and can be cheaper (relatively speaking).

They traversed no straight track during the test. The switch is set to the curved track as well. That is not fair - almost all train sets contain straight track, too (but yeah, they contain more curves).

I wonder why no straight track was used in the test. And I think that battery powered engines don't have relieable results because each battery is slightly different (thus one train might have an advantage over the other). Also, nice category: "comedy"

I made a quick google search and the google playstore's review process takes approximatly 3 days.

Can you share a link to that app? I'm surprised by how active the EV3 development still is

The app is much more limited block and feature wise.

They also had the winter holiday train and currently have the hogwarts express with 30% off, at least in Europe.

Anyways nice to know. I'm sure that this might be useful for some projects. Too bad that no one knows about it (and there is no official/ easy to use way to make use of it).

Hello, I watched an interview about Lego Powered Up and at about 6 minutes in, a lego employee teases that the Boost color sensor has a hidden mode to remote control old power functions IR receivers. Did anyone do any research about it/ try it?

is there a reason why you wrote int in caps and you wrote publ instead of public? Did you try it without the public?

There's also the MonoBrick communication library that supports C# to "remote control" EV3s and NXTs and the MonoBrick Firmware that lets C# programs actually run ON the EV3. Sadly it's not really supported any more. http://www.monobrick.dk/

There should be an option "search" or something like that. It should work

You can't run both motors with the remote since the motors don't use the same plug.

A second motor would probably make the train run faster (but also drain the batteries faster since the actual weight that has to be pulled stays the same). You can make custom remote control profiles in the powered up app (simply select the one controller layout). The program in the screenshot should do the trick. To run it press the start button and then switch to the gamepad "mode".

Actually I'm pretty sure that there will be an adapter cable at one point. But who knows when.

Yes

I think that there might be fluctuations in voltage and current when the motor changes the speed fast (especially with XL motors) which might have effects on the receivers.

There are new all-plastic wheels (they took the metal axles out). They came first with the hidden side train.

There have already been pictures (but more like concept art) of a technic battery box that has the same size as the technic hub

The Powered Up app got a few major updates. There is a general remote layout that you can write your own actions on button presses etc. for.

You can even fit a normal boost motor in the hogwarts express you are space efficient.

The winter village train is way too big. It looks like a small amusement park train while it has the same height as the emerald night or the maersk train. It's a different scale. But maybe that's just me.
