Products that do what PicoVision – A HDMI video stick with dual RP2040 chips (CPU and GPU) does
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…

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…

Hi HN, YC w24 company here. We just pivoted from drone delivery to build gpudeploy.com, a website that routes on-demand traffic for GPU instances to idle compute resources. The experience is similar to lambda labs, which we’ve really enjoyed for training our robotics models, but their GPUs are never available for on-demand. We are also trying to make it more no-nonsense (no hidden fees, no H100 behind “contact sales”, etc.). The tech to make this work is actually kind of nifty, we may do an in-depth HN post on that soon. Right now, we have H100s, a few RTX 4090s and a GTX 1080 Ti online.…

Hi everyone, I'm kinda involved in some retrogaming and with some experiments I ran into the following question: "It would be possible to run transformer models bypassing the cpu/ram, connecting the gpu to the nvme?" This is the result of that question itself and some weekend vibecoding (it has the linked library repository in the readme as well), it seems to work, even on consumer gpus, it should work better on professional ones tho

I wasn't quite sure if this qualified as "Show HN" given you can't really download it and try it out. However, dang said[0]: > If it's hardware or something that's not so easy to try out over the internet, find a different way to show how it actually works—a video, for example, or a detailed post with photos. Hopefully I did that? Additionally, I've put code and a detailed guide for the netboot computer management setup on GitHub: https://github.com/kentonv/lanparty Anyway, if this shouldn't have been Show HN, I apologize!

We developed a tool to trick your computer into thinking it’s attached to a GPU which actually sits across a network. This allows you to switch the number or type of GPUs you’re using with a single command.

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.…

This is a long-running project that started as the proverbial need to scratch my own itch and then somehow evolved into a full-time job of the past 6 years. Link: https://bvckup2.com I thought I'd do a Show HN for two reasons. 1. I obviously want to show my baby to those who haven't seen it. Its primary purpose is to do very fast file replication. If you are familiar with "robocopy /mir" - same idea, but on steroids. Lots of them. It can be used for both mirroring and archiving backups, among other things. It is light, very small and it is really quite fast. Half of the…

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

Hey all! I've been using this stack personally for a while now and decided to automate it a bit by turning it into a template I can reuse. Hope others might find it helpful!

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…

This is a GPU "software" raytracer (i.e. using manual ray-scene intersections and not RTX) written using the WebGPU API that renders glTF scenes. It supports many materials, textures, material & normal mapping, and heavily relies on multiple importance sampling to speed up convergence.

Howdy! Keeping with the trend of being influenced by https://diskprices.com, I wanted to make a resource for GPUs on eBay that also take into account a performance metric I tend to look at when checking GPUs. It's still a work in progress, but it's at a state where I think some of HN might find it useful! There are a few things that I have planned to add in the coming day(s): 1. Filters for compatible slots and connectors 2. Expand for different eBay regions, rather than just US focus Let me know if you have any questions or want more / different filters on the page or if I…

I am making a virtual HDMI monitor using Viture Pro XR glasses and an SBC ( currently OrangePi 5 Plus because it has HDMI-in ). What it does is map the frames from the HDMI input onto a virtual display that is controlled by the IMU data from the glasses ( 3DOF only ). I've put AR in quotes in the title because many won't view those display glasses as true AR but by tracking the head movement it comes close. I am trying to build kind of a "low cost" version of a virtual screen that acts like a monitor and can be connected to anything that has an HDMI output I started off using the official…
