I’m Joshua Hanlon, and in this video I’m at CES taking a deeper dive into what’s actually inside the LEGO Smart Play “Smart Brick” and how the whole system works. We’ve shown the functionality in demos and Star Wars models before, but here I wanted answers to the questions I keep hearing from fans—starting with charging. Alex walks me through the wireless charger: it’s USB-C on the pad, includes a USB‑C to USB‑A cable in the set, and the pad can charge two Smart Bricks at once. In a heavy play session (constant motion and sensing multiple tags), LEGO estimates about 45 minutes of battery life, and about two hours to recharge from fully depleted. We also compare the Smart Brick’s form factor to a standard 2x4: same footprint, but it’s five plates tall instead of three, which helps with visibility and getting it in and out of builds. We talk about building it “hidden” inside MOCs—what sensors still work, how light output is designed around specific studs, and how tags can be sensed from a couple plates away. Alex also breaks down the tech inside: battery, tiny chip, color and ambient light sensing, motion via gyroscope, a microphone for “blow out the candles” interactions, and brick-to-brick connectivity at “bedroom scale,” with support for 30+ connected bricks.
