24 alternatives to Mini Christmas Trees with addressable LEDs and RP2040-based controller
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…
Mini Christmas Trees are 23cm-tall decorative devices featuring WS2812 addressable LEDs controlled by an RP2040 microcontroller running MicroPython firmware. Users can create custom lighting animations synchronized to… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Mini Christmas Trees with addressable LEDs and RP2040-based controller launched in 2022; newer entries below may have overtaken it.

(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…

This is a little toy project of mine that lets you simulate digital logic graphs. It was inspired by Minecraft's Redstone and the Piet esolang. It's got some serious drawbacks-- you write circuits as PNGs and simulate them with a Python interface. It's slow to run and slow to experiment with. And it is certainly difficult to use for people with any kind of color blindness. But despite that, I hope this can still be a fun toy!

Repo: https://github.com/valdanylchuk/xcc700 Hi Everyone! I just wrote my first compiler! - single pass, recursive descent, direct emission - generates REL ELF binaries, runnable using ESP-IDF elf_loader - very basic features only, just enough for self-hosting - treats the Xtensa CPU as a stack machine for simplicity, no register allocation / window usage - compilable on Mac, probably also Linux, can cross-compile for esp32 there - wrote for fun / cyberdeck project Sample output from esp32: xcc700.elf xcc700.c -o /d/cc.elf [ xcc700 ] BUILD COMPLETED >…
