A Radio Controlled Lego-Powered Submarine

On The Brick Experiment Channel, they show how they built this really amazing R/C controlled Lego-powered sub housed in an acrylic cylinder and using an actuated 60ml syringe as a ballast tank.

The sub also has a pressure sensor, a distance sensor, and is controlled by a RBpi Zero 2. The engineering on this thing is jaw-droppingly clever.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
