24 alternatives to Homemade rocketship treehouse – hardware to custom OS
(This was previously submitted as https://news.ycombinator.com/item?id=2246856) The Ravenna Ultra-Low-Altitude Vehicle is a backyard rocketship treehouse nestled in the Seattle neighborhood of Ravenna. Click the link to see a demo video (http://rocket.jonh.net). The hexagonal treehouse is about 6.5 feet (2 meters) across at its widest point. The frame is welded mild steel with riveted aluminum siding. 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…

Repainting the iconic IKEA PS 2014 lamp into the Deathstar from Star Wars has been a popular IKEA hack for quite some time. This variant additionally replaces the manual, rope-operated mechanism to open and close the lamp with a remote-controlled motor. The firmware is based on ESPHome, and its excellent Home Assistant integration enables one to implement higher-level features, like a "sundial" where the aperture of the Deathstar follows the sun elevation throughout the day (see the timelapse video). That said, I will not consider this project as complete until the Imperial March can be…

ohai! I've released Lightwhale 3, which is possibly the easiest way to self-host Docker containers. It's a free, immutable Linux system purpose-built to live-boot straight into a working Docker Engine, thereby shortcutting the need for installation, configuration, and maintenance. Its simple design makes it easy to learn, and its low memory footprint should make it especially attractive during these times of RAMageddon. If this has piqued your interest, do check it out, along with its easy-to-follow Getting Started guide. In any event, have a nice day! =)

Me and a few friends made this design document as part of our entry to the UK CanSat competition where a high school team is required to build a probe to be launched. The probe must serve some purpose, and ours was to map the temperature and pressure of the air at different altitudes. We had the opportunity to launch it a week ago and you can find the video of our launch here: https://drive.google.com/file/d/16bsLzxjP7OWRqVvCB62cLv7QYLR... During the launch we reached 400m above sea level, and the can pulled 70gs successfully. The parachute and can stayed intact.…

Hello HN, these Mini Trees have a custom circuit board with WS2812 addressable LEDs on one side and a controller using an RP2040 microcontroller on the other, all inside a CNC'd Foamex PVC case. They stand around 23cm (9") tall. The firmware is written in MicroPython, which can be modified or replaced. Power is provided via USB-C, which is also used for programming. There is also a web-based animation sequencer to create lighting sequences in time to arbitrary audio, examples of which are on the linked page. This is similar to xLights (https://xlights.org/), but much less…

Today is the 55th anniversary of Apollo 8. I figured it would be fun to make a CAD model with a space for a model rocket engine and also as an augmented reality model. The tutorial is for Fusion360 but the steps can be adapted to most CAD programs. I would love to know what you all think!

I made this site using R3F (https://github.com/pmndrs/react-three-fiber), a React renderer for 3JS (https://threejs.org/). The celestial bodies are Three.JS meshes. I used loaders (namely 'useLoader' from R3F and 'GLTFLoader' from 3JS) to import 3D models, such as International Space Station. More on loading models in R3F: https://docs.pmnd.rs/react-three-fiber/tutorials/loading-mod... I've future plans for this side project. It would be great to hear from the HN community before diving into them. Enjoy! P.S: Getting an empty…
