And it also doesn't work in Internet Exploder?

It works for me, what browser / platform do you use? Maybe try incognito mode?

I have created an improved signal arm. I have been using signal arms for my trains for years but I did not really liked the way they looked (using normal 1 x 1 round bricks) and also it was difficult to adjust them. For the old version I also needed a counter-weight (lead). For the new version I cheated a little bit since there are no 4274 with friction as far as I know, so I added the friction by wrapping some plastic around the ends (you can't see it and it does not damage them pens). I used some relatively new parts to let the arms work including a 'Fez' as counter balance. I also used the 20482 parts on the top for possible signal lights (I already have black enamel coated copper wire for the possibility of adding LED's to the masts). For now I have created five, but I have wired only one (using original LEGO thread). Here is the lxf. This is what an original Dutch arm signal looks like: These are the typical Dutch signals, they are not used on normal lines, but they are still used on Museum lines. The round end shows that it is a main signal, without the round end it is a distant signal. I will automate them using a small lineair servo, I also created some dedicated Bluetooth LE controllers for it (Adafruit Bluefruit compatible), still need to solder / test them (first version so they probably will have some bugs). One could of course also use a LEGO dc motor or servo (and WeDo 2.0 / Boost).

He (Ben) does not have the same wheels AFAIK :( You can better use the wheels with a cross axle but I guess you want to fit them into the normal LEGO wheel holders.

Working on that with some parties :)

Very nice @Jim, a lot of work, but you ended up with a very nice review + the reveal images. How many hours took the build itself approximately?

It uses a planetary gear system, so probably one of these has an issue.

Very nice! Great idea. Now the iOS version ;)

Very nice job @mdbz I agree with @Redimus about the proportions of the tender, Maybe making the tender also 8-wide could also improve it. Dark blue + yellow works very well indeed. Glad that LEGO gives us more and more parts in newer colors!

Train enthusiast @mdbz just presented his Dark Blue + Yellow 4-6-4 Hudson type steam engine inspired by real engines like the Canadian Pacific 2816 and Union Pacific 844. Check more images of this marvelous build in Train Tech.

And the tear down continues! What's that... HUB No. 5? Where are my Torx bits ;) I like this one actually better than the one from the Powered Up train. You can generate sounds on the train! Like blowing the whistle. Alas the sounds are the same for the two options (Cargo train 10875 and Steam engine 10874). There is also another Duplo train coming in fall and I have strong reasons to indicate it will use the same base (but I can't elaborate more on it to not cause a friend under NDA any troubles). They used a light pipe from the RGB LED to the front of the base. The bluetooth profile is pretty much the same like the HUB 4 (Powered Up for City). Much simpler profile than that of the WeDo 2.0 at least.

They will fit together very well I think!

In the US they are delayed, I received the passenger train yesterday, in the EU they are already available. Maybe there is still an issue with FCC rules (Bluetooth e.d.) Apple warned me about that (in general), US customs is very particular on such a things.

Ali is conducting his PhD research on Crowdsourcing platforms and includes LEGO Ideas in his research. Please take a minute and fill out his questionnaire.

Very nice job! Neat little town too!

I visited Shapeways some month ago, they do an impressive job, but I still thing the BBB wheels look even better. There is now also some progress in 3D printing molds, that would help bring costs down for e.g. BBB.

Well, you could replace the portholes of the engine with stickers. An other color scheme (e.g. Union Pacific) ell. might also work well? Do you already have the engine?

Yups it is a simple DC motor. And yes a convertor would be very easy to implement for LEGO.

Well the possibilities are endless of course. For the 60198 I have decided to remove the base of the battery box, that way I have a little more clearance between the sensor and points/switches. I am working on Swift playgrounds and found that it is quite hard to debug those playgrounds without some bluetooth low energy UART that mimics the HUB and/or Remote. That is why I implemented a simple UART based in Adafruit code for nRF52 (in my eyes the these nRF5x based solutions by Nordic are the only at least somewhat friendly Bluetooth Low energy implementations). So in case you own some nRF52 based product from Adafruit or compatible (I use my own custom nRF52 board with the same firmware): https://github.com/jakorten/UpControl/tree/master/PU_Debugger_nRF52

Ah, no I meant the hub indeed...

The LED works exactly the same as the one of Boost, so I don't think it is used for that. I don't see any other sensors, would be cool if LEGO would have a motion sensor in it but I'm pretty sure they don't.

Yups. But that is typical, one also would need that with what item is attached to what port since a disconnect message also seems to be generic (same for motor and sensor). Very nice find, how did you reach that solution (just trying I guess?)? Seems LEGO keept all items basically the same!

Great to hear, that allows even for much more possibilities! How do you get the remote to report back to your software? Do you send it a sensor message just like with the color sensor (e.g. [0x0a, 0x00, 0x41, port, sensorMode, 0x01, 0x00, 0x00, 0x00, 0x01])?

Yups it works very well @Mr Hobbles LEGO did a great job there, we couldn't get it working that well when using our own hardware (with high school / college students). Fortunately it will even fit under the locomotive of 60198 so without a lot of change people can integrate it into their own sets, luckily the sensor is not a big brick but has an L-shape.

Google wants to know where you are and what you do, that's their main business ;)
