It’s a 2 x 4 Lego brick with a speaker/lightsand custom ASIC built-in, with light and sound sensors, reacting to IOT beacons that allow different sounds or light sequences. And it’s rechargeable like an electric toothbrush. It also has accelerometers that change the sounds as you twist and turn them around. The sounds themselves are generated, with the speaker driven by an onboard synthesiser.

Just like the Light & Sound sets from the 80s.

Except now it has an accelerometer too, and the sounds are more than just a siren, so your spaceship can make a swoosh noise when you fly it around. This is what we wanted.

Looks like it has an IMU built in, so if it has wireless it could easily integrate with some kind of software system like those. Seems like right now it's just so your space ship can make vroom sounds

Doesn't it have sensors too? I recall reading about proximity sensors to other smart bricks, as well as accelerometer and orientation sensors.

As far as I can tell, it's Amiibo, but Lego. The 'smart brick' has a couple sensors, speakers, and lights, including an NFC-ish reader. The minifigs and 'smart cards' are your amiibos that tell the brick what to do.

It definitely doesn't look like it's aspiring to be the programmable environment that Mindstorms was. There may be a way for a tech enthusiast to make custom smart cards and logic, but I wouldn't count on it. Would be happy to be proven wrong.

Its not mindstorms but Edison is LEGO compatible and is a nice platform. https://meetedison.com/

It's disappointing that the company famous for making toys today that work with 50 year old bricks couldn't have kept things in the Mindstorms "ecosystem" even if replacing/new - so that those in the know could keep building on it.

Very interesting!

To be clear, the SMART brick is not much of a "programmable logic toy", topping out at "if near X, play U sound".

Your last paragraph is spot on though.

Yes, they made this explicit in the "fact sheet"

>... LEGO SMART Bricks can talk to each other directly - no app, central hub, or external controller required.

Yes, I thought the same thing.

My son loves Lego Mario and the app. He'll even go through the building instructions of kits he doesn't have just to see how they are built. The instructions in the app are super clear, animated, and the model can be rotated at any step to check whether the real-life model is correctly built.

Going back to paper instructions after using the app is a pain.

> It shouldn't be hard to print pieces that can snap together

I have some news for you. Lego piece tolerance is nuts. I think it is down to 2 micrometers. You can't achieve that in consumer 3d printers.

Now, you can make something that kinda works like lego but it wont have the structural integrity for advanced builds.

Printed pieces typically only have a single purpose, and lego-like snap together tolerances are hard to get working right with a 3d printer. Hell, they're hard to get right for the mass produced lego no-name duplicates. It can be fun to design shapes in tinkercad, but not as accessible for small children as just putting plastic bricks together.

I actually think what you suggest _would_ be brilliant if there was a printer that printed as nice and detailed parts as Lego does from ABS. The digital ecosystem for that would be crazy.

But.

Modern consumer printers are way better than decade ago but they still sort of suck if you want any fine details.

"It shouldn't be hard to print pieces that can snap together."

It's actually quite hard to print pieces that are functional and look nice.

Modern consumer 3D printers sort of suck for small details still. If all you print are Lego Dublo sized parts. And print them from ABS. You might succeed _sometimes_.

PLA the cheapest default plastic for filaments for extruders loses fit quite fast (I've tried). So ball joints etc will get loose pretty soon.

"Would there be any downside to this approach?"

Well, the adventure currently is the printing part and it's mostly not fun but one of those activities masochistic engineers (like myself) take up as a hobby.

The consumer 3D printers are improving! Maybe one day. But the material physics are not that comforting there.

Not to discourage you, but it sounds like you'd be getting into a nerdy programmer dad hobby instead of just giving your kids toys. I doubt your children would be interested in watching you for hundreds of hours while you learn to use 3d modeling software and debug printer feed speeds. And once they were old enough (10-13+) to appreciate technical slogs, why wouldn't they do something cooler like make actual robots instead of reproducing a toy that you can buy a much better version of for $10?

3D printing would be good at making figurines and such, but you can't easily replicate the Lego system's modularity without their high tolerances.

That being said, it should be feasible to make something that allows easily programming Arduino and raspberry pi to interact with legos, similar to how their Mindstorms line worked. That would be the best of both worlds.

There are off-brand budget Lego blocks available and they're (in my experience) all awful. Legos are very precisely manufactured to fit together smoothly, if the off-brand ones made in a factory can't replicate that then I don't have much hope for small-scale 3D printing.
