Cool, thanks for your feedback, and this is confirming what I thought as well - thanks!

Hey!

I'm playing with the idea of trying high altitude balloons, and am thinking about potential setups. It seems normally such a weather balloon is equipped with camera for pictures, data logger with sensors (temp, pressure, altitute etc.), and GPS plus some sender (GSM, LoRa, etc.) to get coordinates home for retrieval after landing.
On a quick glance all of this would be easily provided my m5stack, but I'm wondering what the best option is.

With the Core I can capture everything (gps unit, lora module, env unit, sd card for logging) but I'm not clear on how to best connect camera (as the cam is it's own esp32). But this gets heavy, and I don't need the built-in batteries, which won't make it through the temperature in the stratosphere.

For weight I'd prefer the atom series but I can't see a lora unit there (which I'd prefer over gsm), and not sure if I can get all the peripheral attached (sd card, env sensor, gps) at the same time (without soldering and rewiring things at least).

Theoretically I could also build from timercam, but again would need to attach quite a few sensors and sd card on top (and again, no lora unit available).

Any ideas, or anyone who has done this before? Any general concerns of using m5stack in a high altitude environment (temperature concerns etc.)?

Same also with uiflow website - it really should be https, then it could also add PWA features to be installed as app, which would be amazing.

Someone did control PF using the stick C's built in IRLED but can't remember how.

So there's existing integration for that into MakeCode (which is also blockly based I believe) and then also the regular Arduino lib. Also the whole IR protocol is documented officially by Lego. But the MakeCode integration seems JS based (not Python based), and I also don't see a good waqy to integrate the Arduino lib into the UiFlow custom component editor. So probably whoever did this before just wrote regular Arduino code for the M5Stick using the Arduino library.

If I ever find a lot of time I might try to reverse engineer the existing code, and redo as a custom block in UIFlow, but not sure if this will ever happen ;-)

There are instructions on how to build NXT>PF leads but I haven't had time to revisit.

I'm also gonna look into that :-)

Oh wow, sorry for missing this existing thread. Not exactly what I was looking for (as I was hoping for the infrared connection) but still what I need to solve my problem. Will probably then get the base-x module and solder myself the cable connections (can't seem to be able to buy them anywhere anymore).
Thanks!

Hey!

I wanted to let my son experiment a bit with M5Stack and Lego. I've seen that there is a module to control Lego motors, but this seems to be rather for mindstorms motors (EV3 or NXT seem to be the notations). However, many cheaper Lego models come with Lego 'Power Functions' motors, which won't work with this module for all I can tell.

I was thinking through different options, and finally felt like the easiest way is to just emulate the IR remote with M5Stack, which in theory would be pretty straightfoward to do. There are even some libraries to do so, but none seems to be compatible to UIFLow blockly, which my son would use:

Is there any good way to import these into UIFlow blockly to use for an 8 year old?
Might it be an option to integrate this by default into UIFlow, as it is a cool option for many users.
