Thanks @JintaiZ :) By the way: all parts have subtitles.

Hi, a few weeks ago I started a tutorial series on youtube. It's about how to program the lego powered up hardware with the Powered Up App (Lego Boost, lego Control+ and the wedo 2.0 sensors are part of the powered up hardware). The complete tutorial is 100% free. So far most of the stuff is pretty basic but it will get much, much, much more complicated later. I promise that ;) (People that saw the german version of the tutorial might know that already) There will be a new part each wednesday.

There is a sound converter from the community.

I would have loved to back the campain but kickstarter only provides credit cards as payment option and I don't have one.

The EV3 has a USB host plug and can boot from SD cards. You can replace the complete OS with something else and there's e.g. ev3dev which is based on the debian linux distribution. You can make very powerful and advanced things with it (e.g. interact with the lego dimensions toypad, run a webserver with a website to e.g. remote control the ev3 etc). However stuff like that is very complicated and requires fundamental knowledge in computer science etc. The new hubs are much simpler to work with but provide enough features for almost all of the users. Personally I think that it simplyfies a few too many things (there is no real options menu to enable/disable bluetooth or set the sound volume or disable the button noise, no official file browser to upload your own sounds or python libraries, problems with the documentation, no open source firmware etc). In the end the question is how much knowledge you have in computer science/linux and what your expectations are. /edit Also, the EV3 is longer in the market so there are more programming options. This is supported by the fact that the micropython os of spike/ robot inventor basically only allows python and layers on top of that (e.g. the official scratch-like environment). There are many programming languages that work out of the box with EV3DEV but most of them are text-based. So it kind of depends on which programming language(s) you want to use.

https://drive.google.com/file/d/1PzbDRNlE9fx17xsK13FwvFTwFCMhaTiU/view?usp=sharing the spike prime software version 1.0.0

An open source firmware would help with that but there is none. Heck there isn't even an official file browser to copy libraries to the hub.

I think that ev3dev has a better implementation for the irlink

The wireless protocol only describes how a smart device and a hub talk to each other. No information about the uart protocol (the ev3 hdK contains a bit about it), no information about how the hub or the sensors work. The ev3 had open source firmware and hardware schematics for both the ev3 brick and all the sensors

Regarding compatibility: the wedo 2.0 hub lacks a bit of compatibility. It was the first hub in the new system and can't be updated. That's the reason why the free programming area of the powered up app doesn't support it.

You can find the 64 bit windows usb driver at http://www.legoengineering.com/rcx-usb-tower-support/ BTW linux has a driver integrated into the kernel (although it needs some permission tweaking).

No. But you can do a simple communication via light or something similar.

I think that support for generic gamepads will not work with 99% of the bluetooth gamepads, The hubs use BLE but most gamepads use BTC. The PUP remote however is another story since it uses BLE.

Might be the disney train or the winter village train. Both look kinda similar

The "Make" area of the app can control a maximum of 4 hubs in the same program.

I prefer the physical remote, too :D Anyways. I think that there will come a profile designer in the future. So that might solve the issues of looking not so nice.

I'm wondering a bit why you are complaining about the official layout. You can always use the city control layout in the "free programming mode" to control trains.

Yes I have but I haven't seen that you made a library for that.

Hmm. I wonder if the dexter industries libraries work: https://github.com/DexterInd/EV3_Dexter_Industries_Sensors/tree/master/EV3_arduino

Did anyone compare the PUP UART protocol to the EV3's UART protocol?

oh lol, thanks for the heads up everyone. I should have realized that.

But now prices have gone up :/ 40€ for a hub. That's almost lego price

I think that the city hub can already be used in a very limited manner. The sensor might not work. https://github.com/pybricks/support/issues/47

Pybricks is pretty well documented from what I know. The SPIKE Prime Hub however lacks much documentation. There is much you can't do with the documented python stuff and don't even think about doing it with scratch. However it's possible with undocumented stuff Other Powered Up Sensors: https://www.facebook.com/groups/SPIKEcommunity/permalink/1124008337977397/?__cft__[0]=AZXinCrJiQv1iDOyp-gnOIxMZR-tyyyTT35fS1vd0w35ycX5h3HBMJ95Hb9aG6htKnw9MNHnqV1TzCrn1PMbgN65F5DbVKie-X48fTtEa37-UzLJ2GO1DBR2O4Ro-goCDP4DGThIE1NtKlJLjNSVodMA&__tn__=%2CO%2CP-R Delete all programs: https://www.facebook.com/groups/191742648593746/permalink/204992223935455/ Conenct to other hubs via BLE: https://github.com/nutki/spike-tools/blob/master/hub/lwp.py Load stuff from another file: https://www.facebook.com/groups/191742648593746/permalink/207030797064931/?hc_location=ufi And much more

You can find the scratch documentation in the settings at "Help". The "simple" python commands are documented. It's very limited. There is a lower level python library that isn't documented but required to access unsupported sensors (boost color and distance sensor) and BLE.
