There is now official documentation for the Bluetooth protocol used by the Powered Up product line: https://github.com/LEGO/lego-ble-wireless-protocol-docs The community has created some tools to interact directly with Powered Up and Boost hubs. Here is one example: https://github.com/nathankellenicki/node-poweredup That tool supports basically every ...

Each train needs the following two components: Hub Train motor I'll assume you purchased a second set of these to convert your 9V train with, since you're asking how to control both trains using the same remote. The LEGO Powered Up team has provided an FAQ for Powered Up which contains instructions for how to pair multiple Powered Up Smarthubs with one ...

Let's take a look. The first step to disassembling the motor is removing the small Philips screw on the bottom: Now there are a pair of gray tabs in the back white section that we need to release. I found it easiest to cut them down with a knife. Once those are free, the white section slides backwards away from the motor. Try to do this gently, as there are ...

I was curious about this, and TLG was willing to provide me with one of these motors, so I opened it up. I was able to get the outer shell off by cutting down the 4 tabs on the outside. This motor does not appear to be meant to be opened and put back together. These tabs hold it together very firmly and I wasn't able to move them out of the way without ...

The bulk of the space inside the Powered Up hub is consumed by the housing for the 6 AAA batteries. A small portion of the top of the hub contains the main printed circuit board. Here's how it looks removed from the hub: And here's another shot showing the back: The main chip is very similar to the one used in Boost. It uses an STM32F030 from ST ...

There is an alternative app called BrickController 2. This open source software is available for both Android as well as iOS. This application is actively developed and its maintainer can be reached on Eurobricks forums. You can also report and discuss any issues there. The application is universal compared with solution offered by LEGO since one device ...

There do not appear to be any compatible connectors available currently. You can obviously splice cables from the official components, but that's expensive and makes those components unusable. I hope that someone has a better answer, but the best that I've been able to do so far is to use a modified SATA connector. I first saw this in a video that ...

LEGO calls this communication protocol the "LEGO Wireless Protocol" (LWP). The documentation is publicly available at https://lego.github.io/lego-ble-wireless-protocol-docs/. There is also a GitHub repository that provides the source of this website at https://github.com/LEGO/lego-ble-wireless-protocol-docs. Because of this, it seems reasonable to expect ...

If you want to “turn on and forget” you might want to look into obtaining a circle of old 9V track (metal rails produced by LEGO until 2007) and a power supply, plus a 9V train motor. It will not be cheap (the track pieces, especially curves, won’t be too expensive but a working 9V train motor is a $50-$75 purchase) however it will allow you to turn the ...

The main difference is that the 88008 Medium Linear Motor includes a rotation encoder with 1° resolution. Otherwise it weighs a bit more (34g vs 43g), is a bit slower (380 rpm vs 255 rpm) but also needs less power (60 mA vs 41 mA when freely running). For more subtle differences see Philo's excellent motor comparison page (where I got the above from as well)....

Using rshell I've managed dump the micropython filesystem of my hub after updating it to v1.0.03.0034-c3879ab. rshell connect serial /dev/ttyACM0 115200 rsync -a /pyboard ~/spikefw Note: These commands are for linux. (I also managed to partially dump the initial version on the hub v0.5.01.0000-42a938e, but ran into issues with binary files as I was using ...

There's a node.js library that can connect to the Move Hub and control attached peripherals: https://github.com/nathankellenicki/node-poweredup This should allow you to write scripts and programs that can control the motor from your Mac.

As of the Powered Up app version 3.0, this is possible. Old answer: As of August 2018, this is not possible. However, TLG has stated that they plan to add more compatibility to the Powered Up system, and this will likely be available as a firmware update in the future: Q. Will all different Powered Up components (Boost, WeDo, Train, etc) be able to ...

Here's what the main board in the Move Hub looks like from the top: And bottom: The Move Hub includes the following hardware: Motors The two built in motors are fairly standard DC motors. They include optics in the early stage of the gearing for rotation counting. There are two LB1836 motor drivers on the board. They are dual channel parts, so ...

I've tried attaching one of the Powered up motors from the batmobile set (76112) This motor looks identical to me as the WeDo motor (although brickset and bricklink don't list them as identical at the time of this writing) I could not get it to work, all profiles of the fixed build models complain that the external motor is not attached. The free build ...

No, but the damage can be limited and is not externally visible. I don't know the technical name, but each of the 4 corners are held in place with these fasteners: Using a tool of the same diameter (2mm), they can be pressed out by applying force to the end of the fastener at the point shown below: This does damage the plastic slightly where it contacts ...

Haven't done the 10254 yet with powered up, but have converted several other trains... The train motors have the exact same dimensions and the powered-up smart hub has the same dimensions as the battery box of the power functions system. What's different is that you don't need the space for the IR receiver and that the motor is immediately connected to the ...

M Motor (Powered Up/WeDo 2.0) The M motor has a 2.2kΩ resistor between pins 5 and 6. Pin 6 is connected directly to pin 3. LED Lights I don't own any lights yet, but according to this post, they also use a 2.2kΩ resistor, but in this case it is between pins 5 and 3. This pulls ID 1 to ground. Here's the full circuit diagram: Train motor The measured ...

LEGO guide shows the orange blinking appears when batteries are flat. . Have you tried using fresh batteries in your train?

I thought I’d update you on the situation for anyone else in a similar position. I got in touch with Lego via email, it took a while for them to get back due to the COVID-19 pandemic, which is totally understandable. I received a bright breezy fun reply from someone called Ryan who said he would send me replacement battery box and remote. Once I received ...

Yes, the rechargeable battery box would work. However, if your intention is to avoid expenses, you are better off with buying the IR-receiver, IR remote and the regular battery box rather than the rechargeable one. The rechargeable battery box is no longer available from Lego for quite some time now and is getting expensive on the secondary market as well (e....

This isn't possible out of the box, and there aren't currently any adapters available from TLG to support this as far as I know. I did come up with a modification to make this possible, though. My goal was to allow me to modify the hub to receive external power in a way that did not damage the hub and would be totally reversible. Ideally, I wanted a solution ...

As far as I know, this is not possible using the current stock firmware. The battery box can only pair with one device. The UI on the battery box is a single button, and for simplicity the device is either in a mode where it is looking for a device to pair with (flashing light) or already paired (solid light). There isn't a way to pair it with another device ...

Since June 2019, this is possible. See here: https://www.hispabrickmagazine.com/content/2019/06/03/powered-up-ii-powered-up-ii-networks/ Look right at the bottom of the article. The latest version of the Powered Up app (2.2.0) as well as the latest version of the Boost app include new firmware for the Boost hub. After this update it is possible to ...

The current line of Powered Up components uses AAA batteries. The Powered Up team has indicated that both regular or rechargeable batteries should work fine. You will need 10 AAA batteries to control one train with the included remote, or 6 if you are using a smart device as your remote. Here's the battery layout shown in the instructions:

They are in a perforated bag and the entire contents of the bag is listed. You only need some of them in this step and in a few steps later on. I think such bag is called an "accessory" bag and it is common to have the instructions like this for such bag. The first set that comes to mind that did the same was the Big Ben 10253 where on step 269 on page 187 ...

This isn't currently available. The Powered Up team responded to a question about this in May 2019. The gist is that they were able to say that the removable battery holder in the hub was designed with a future rechargeable battery in mind. This can also be inferred directly from the design: They cited several reasons that this isn't yet available, ...

There is a free app called buwizz. It is a great alternative that gives more freedom, and works on Android.
