    Isn’t the “Lego” part kinda just the battery casing with bumps on it, though? Batteries often have circuitry. They have the contacts for connecting it to whatever it is powering… they have a case. Sometimes a plastic one…

    Just for conversation sake. I don’t think disposable legos are cool or anything.

      Check out jerryrigeverything’s video on it. It’s pretty neat. It’s basically just a microcontroller with a battery, nfc coils, charging coils, and sensors. So you place it near other parts of the set and it makes interactive sound effects and lights up and stuff. It recharges with a wireless charging pad and honestly will probably last 10 years+ before the battery degrades meaningfully.
