    LEGO Trains 2022

    But only for city. There have been a few passenger steam locos in other categories. LEGO will stay with powered up at least 5 more years. They made official announcements regarding that.
  3. I'm pretty sure that we got crows or ravens at one point. They are in lego worlds.

    Happy New Year 2022!

    Happy new year everyone :)
  5. Someone did that already:
  6. I doubt that it would be easy. But you can use a wireless BLE communication instead, that should be easier.
  7. Can you post the complete error?

    Powered up sensors DIY

    That's not entirely true. NXT used I2C, EV3 UART (except for backwards compatibility to NXT). EV3 used an earlier version of the UART protocol. LEGO EV3/ Powered Up UART devices have a protocol they follow. It includes a handshake to determine the speed of the communication etc. There has been a project to recreate the prtocol for arduinos but it never worked for me for some reason: It seems to be easier to use your own UART protocol/ a simple uart communication and there are some semi official projects... but I think that they are pretty complicated to get into. You can also configure pins 5 and 6 to be used as GPIO pins but they don't have PWM/ADC. Some examples can be found at and in the official documentation
  9. You have to create a new project to use the import block function.

    New Powerd up hub

    Yeah, it's expensive. But it includes a rechargeable battery, so that's something.
  11. The V1.1 blinks the green led on startup. The 1.0 just turns on.
  12. Nice collection. One note: you can enter the extended PF mode and control up to 16 devices individually. It works with all the normal receivers after V1 and I think that the EV3 IR sensor ignores the extended bit.
  13. The WeDo 2.0 hub is very limited in terms of support because it was the first "powered up" product (before powered up was a thing) and the firmware can't be updated. The ble protocol was updated afterwards: it doesn't support the current BLE commands and thus can't be used with the powered up app. There are some options to control the hub. You can use the official SDK by lego and you can use a few 3rd party projects (but most of them don't support this hub because of the BLE thing). One of the 3rd party ones is node-poweredup.

    RI5 Biped with 5 control+ motors

    I think that this is geared towards more advanced users because a raspberry pi isn't that easy to use. Maybe to collect some measurements for a scientific project, maybe for some KI project or something, something like mapping a room etc. Also, it's cheaper. It might be geared to schools - but it might be too complicated for them. But personally I don't think that this makes much sense. You can get a technic hub for less money, or a technic set with motors if you start from zero. There are python libs to remote control the hubs and you don't waste the GPIO pins of the pi that way.
  15. Back when the EV3 first came out the education software cost money but now everything is free. There are a few differences in software that you should be aware of. Home/Education: 31313 is the home edition but there is also an education set with other sensors and parts, building instructions and some additional blocks (e.g. for the renewable energy set and temperature sensor). Also, the education software features datalogging (at keast the LabVIEW version). LabVIEW/ Scratch: The original EV3 software from 2013 is labview. It's programming interface goes from left to right and the blocks have icons, no text. It also supports older sensors for the NXT model and 3rd party sensors. The labview software doesn't work on current MacOS systems. That's probably one of the reasons why lego started to develop a new software for the EV3 that uses scratch as a base. It's a programming language that many children get teached in the school but the scratch software has limited features (e.g. no support for NXT sensors, the renewable energy set and the temperature sensor).
