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…

In plain words

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 power consumption. It is built for developers and makers creating cyberdecks or embedded systems who need a software interface to manage applications on resource-constrained hardware while maintaining smooth graphics performance through a physical double-buffer system.

Slime OS is an app launcher for the PicoVision (and soon other RP2040 and RP2350 devices). It was originally designed for the Slimedeck Zero , a mini cyberdeck project. However I hope to expand it to other devices and form factors. This README contains affiliate links which help support this project! Slime OS runs in a limited 32-color mode with a 400x240 internal resolution which is interlaced up to 800x480. This resolution should scale well on most HDMI displays. Slime OS includes various libraries which are used internally but may also be helpful when making apps. import slime_os as sos Slime OS Library Description sos.gfx Drawing methods including shapes, text, and other utilities.…from github.com

    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!

  • My microkernel-based OS built from scratch now has basic Unix commands2024 · github.com · ▲69

    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…

  • Talanoa▲346

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    I was at FB/Meta from late 2013 to early 2023, mostly working in the compiler/runtime spaces. I got hit in the spring 2023 layoff wave. I immediately started making games in my newfound free time (a lifelong interest, and I even worked in AA(A?) back ca. ~2000), and in October 2023 I stumbled upon the idea of a roguelike pachinko/plinko game inspired by Luck Be A Landlord. Things snowballed quickly, I started talking to publishers, then worked like crazy through all of 2024, almost the hardest I've ever worked in my career, and launched the game in December 2024. It's sold…
