24 alternatives to Slime OS – An open-source app launcher for RP2040 based devices
Hey all - this is the software part of my cyberdeck, called the Slimedeck Zero. The Slimedeck Zero is based around this somewhat esoteric device called the PicoVision which is a super cool RP2040 (Raspberry Pi Pico) based device. It outputs relatively high-res video over HDMI while still being super fast to boot with low power consumption. The PicoVision actually uses two RP2040 - one as a CPU and one as a GPU. This gives the CPU plenty of cycles to run bigger apps (and a heavy python stack) and lets the GPU handle some of the rendering and the complex timing HDMI requires. You can do this…
Slime OS is an open-source app launcher designed for RP2040-based devices, particularly the PicoVision which uses dual microcontrollers—one as CPU and one as GPU—to enable HDMI video output with fast boot times and low… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes. Prices are shown for the 1 we have checked on their own sites.

- 2IMI made a tiny camera with super long battery lifefrom $200/mo▲843
Hey HN! A few years ago someone kept trying to steal my motorcycle, so I decided to make a small camera with really long battery life to catch them. The hardware/software is totally open source, but the companion app only supports macOS currently. (I'm a big fan of native apps, and didn't want to block releasing on Linux/Windows support.) I wrote some blog posts about the process: PCB design: https://toaster.llc/blog/pcb Enclosure design: https://toaster.llc/blog/enclosure Image pipeline:…

I've been hacking away lately, and I'm now proud to show off my newest project - The Icepi Zero! In case you don't know what an FPGA is, this phrase summarizes it perfectly: "FPGAs work like this. You don't tell them what to do, you tell them what to BE." You don't program them, but you rewrite the circuits they contain! So I've made a PCB that carries an ECP5 FPGA, and has a raspberry pi zero footprint. It also has a few improvements! Notably the 2 USB b ports are replaced with 3 USB C ports, and it has multiple LEDs. This board can output HDMI, read from a uSD, use a SDRAM and much more.…

GodotOS, an operating system interface created entirely in Godot! Browse folders, edit text files, view images, play games, and more in one cohesive polished interface that can even be used on the web. Note that GodotOS is more of a toy than a serious project. It's meant to push the limits on UI design in Godot while creating a desktop that is minimalist, distraction-free, and aesthetically pleasing. Any feedback is greatly appreciated! Apologies for posting again, but I forgot to include "Show HN" in the title, and when I did post yesterday Hackernews almost immediately went down for over…

I thought it might be a fun one for the HN crowd, to celebrate the launch of our latest product we're running a demoscene competition to see what people can squeeze out of it - details here: https://shop.pimoroni.com/pages/win-a-500-gift-card-in-our-p... PicoVision sports two RP2040 chips (one on a PicoW with WiFi and Bluetooth) acting as GPU and CPU allowing you to drive a HDMI display with smooth fullscreen animation - it can even play DOOM! There's a heap of interesting features built into the GPU firmware including support for "soft" (?!) hardware sprites, palette…

This project contains no code from Linux, BSD, Minix, or any other OS. Everything up until this point is written entirely from scratch, including a pure microkernel (that only implements multiprocessor priority scheduling, memory management, and interprocess communication), a work-in-progress implementation of the standard C library, and a variety of servers that provide drivers and other essential OS functionality. At the time of writing this post, the servers provide drivers for the keyboard, NVMe SSDs (that works on real hardware), a Unix-like virtual file system (with a single root…

Hey everyone, I previously introduced an open source private home security camera in 2024, which uses OpenMLS for end-to-end encryption: https://news.ycombinator.com/item?id=42284412. It was called Privastead then and it's now renamed to Secluso. John Kaczman found my project from here and has been working on it with me over the last year and half. We've made a lot of improvements to the software, which we would like to share with you: - You can now set this up on your Raspberry Pi in less than 5 minutes with no technical expertise using our easy-to-use GUI deploy tool. We've…

We ported pbrt-v4 to Julia and built it into a Makie backend. Any Makie plot can now be rendered with physically-based path tracing. Julia compiles user-defined physics directly into GPU kernels, so anyone can extend the ray tracer with new materials and media - a black hole with gravitational lensing is ~200 lines of Julia. Runs on AMD, NVIDIA, and CPU via KernelAbstractions.jl, with Metal coming soon. Demo scenes: github.com/SimonDanisch/RayDemo

I've been trying to make accessible and beautiful GPIO pinouts since I started one for the Raspberry Pi in 2013 [1]. I've since given the Raspberry Pi Pico [2] and Pico 2 [3] microcontrollers the same treatment when they launched. Recently I've updated these with a new "Upside-down" view to complement the rear view, giving a pinout in the right orientation to match your project. The Pico sites are all hand-coded single HTML pages with supporting CSS and minimal JS. They are set up to optionally install as a "Desktop" web app. They also degrade into a somewhat usable table in lieu of CSS and…
