Mindstorms 2020

Try this: hub = CPlusHub() if hub.battery.voltage() < 6500: hub.shutdown() You can also power off the HUB holding the power button for a few seconds

Yes! It's so simple!

No. All motors have variable speed. Someone has an optical sensor to get/set relative/absolute position (so, you can control "by turn" or "by angle") All info about LEGO Motors: https://www.philohome.com/motors/motorcomp.htm

There is other work to do, but this is a good starting point (the PCB used in this image is not designed for this purpose... I have used this only for a test)

I initially unsoldered two connectors from a HUB. After that, I bought a batch of 10 pieces from China

I don't kown... I'm an early beta tester, still before this pre-public beta version.

Great job @Mr Hobbles

Something like this ;)

Interesting... An 3D printed custom connector?

Yes ;)

You have only to force "bootloader mode" (long press on the Power button) and the PU App re-flash with the LEGO firmware ;)

Yes, sure!

In the next wave of Technic sets there is present a new Powered Up "Battery Box" (see on the left side of the image) A first image of this component was presented last year, during the RLFM days (note the difference with the Control+ HUB, on the right side of the image) Seems to have only two I/O port and I think it's no needed to use with App. It's a stand-alone battery box? It's have two motor inside like the Boost HUB?

Yes! It work well. Remember, however, that this firmware is still on "alpha" stage.

Thank you. I hope that TLG add in the future a "generic" sensor in his PU firmware to make more simple to develop a custom sensor. Yes... in the next days I open a new topic about this project.

Take a look here: https://docs.pybricks.com/en/latest/

It's not mine, @JopieK. I'm only alpha-tester ;)

it's a very strange behavior... @Matteo you are italian like me. Tomorrow contact me via PM, to try with other test.

No. Try removing the battery, push the power button, and reinsert the battery again.

It's yet an Alpha version, but it's very promising!

Do you have only one hub? In this case, try to force a new firmware update: push the power butto until the led light become purple. Then, start the App e try ti connect to him. When the LED change color, release the button. Make this operation without any motors connected.

Hi @Matteo, have you tried to update the firmware of the hub, with the PU App?

I have a "good" knowledge on the PU ecosystem (see my "magnetic sensor" for PU) and the "speed of change" (new firmware and new App releases) is so slow to leave me doubts. I made some experiments with LCD and Powered Up, using LEGO UART Protocol... It's a possibile to do, but I repeat: it's not the same thing to that have all in one.

@Coder Shah, where is the "interface" in the PU App? You can't design your UI as you like. There are a lot of other problems moving the UI to another device, instead of have a mini LCD on board. Depends on the use. Think a school classroom where the boys using the EV3 to develop a production chain (don't forget the "daisy chain" feature of EV3) and need to display the progress/status of the production system. In italy (but I think in many others place), the EV3 bricks is large used on the school system because is simple to learn and useful to build robot/structures thanks to LEGO Technics elements.
