On the highly-recommended Brick Experiment Channel, "BEC" (the unidentified, silent LEGO engineer you never see or hear) tries his hand at building a quad drone using LEGO bricks and other LEGO components. The only non-LEGO parts he uses are the battery, the receiver, the flight controller, and a motor driver circuit.

For the flight controller, BEC used the Matek F411-mini. For the motors, he used four LEGO L-motors [88003-1].

Besides the cool LEGO drone he ends up with, I love watching his experimentation and iterative process. And like many fellow 'tubers such as Jimmy DiResta and Primitive Technology, the un-narrated video is kind of mesmerizing to watch as you hear only the sounds of making. Read the rest

This video of radio-controlled model trucks look like an autonomous Ford Bronco off-roading at the beach. It's actually a Traxxas TRX4 Sport radio-controlled truck that's just 21" in length. Excellent smartphone video shot on a Samsung Galaxy S9+.
