Building a Lego-powered Submarine 3.0 – balloon and compressor
Watch as the Brick Experiment Channel builds a 3rd iteration of their Lego submarine. They make it look so simple and there is a soothing ASMR quality to the process.
Depth control is done with an air-filled balloon and a Lego-compressor. Steering is done by turning the propeller direction with the help of linear magnetic coupling. Otherwise it’s more of the same as before. Swimming pool and lake tests at the end. Enjoy!
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.
