The Ravenna Ultra-Low-Altitude Vehicle: A Rocketship Treehouse

The Ravenna Ultra-Low-Altitude Vehicle: A Rocketship Treehouse – the makers write –

Rarely does building a treehouse require welding, grinding, painting, riveting, bending, crimping, plumbing, brazing, laser cutting, sound design, printed circuit board fabrication, thousands of lines of C code, distributed network protocols, sewing and embroidery.

Ours did.

The RULAV is a hexagonal capsule, 7.5 feet (2.3 meters) high, atop a tripod 7.5 feet (2.3 meters) high, for an overall height of about 15 feet (4.6 meters). It is about 6.5 feet (2 meters) across at its widest point. The frame is welded mild steel with riveted aluminum skin. It contains nearly 800 LEDs forming dozens of numeric displays spread across 14 control panels, each with an acrylic face laser-cut and etched with labels such as “Lunar Distance” and “Hydraulic Pressure”. The pilot controls the rocket using a joystick and panels full of working switches, knobs and buttons. Underneath the capsule are three “thrusters” that shoot plumes of water and compressed air under the control of the pilot’s joystick, simulating real positioning thrusters. Takeoff and docking sequences are augmented by a paint-shaker that simulates the vibration of a rocket engine. Sound effects complete the illusion, with a powered subwoofer that gives the rocket a satisfying rumble.


8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

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.

  1. That is AWESOME!!! Talk about the luckiest kid ever- all he needs now is a Moon rover. 🙂

  2. Not that it’s at all appropriate for that age kid but I’ve always wanted something like the LEM trainer. (Yeah, it’d probably kill me, but I’d go out in style).
