PicoVision – A HDMI video stick with dual RP2040 chips (CPU and GPU)

What it does

In the maker’s words, at launch

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 modes, scrolling, and more! The GPU and CPU share a pair of 8MB PSRAM chips that are swapped each frame using an analog multiplexer to allow them to pass the framebuffer and other information between them with no overhead during VSYNC. It also has a HDMI connector, a microSD socket, GPIO pins, a Qw/ST connector, some buttons, and audio out meaning there are a lot of possibilities from gaming to digital signage and anything inbetween!

  Slime OS – An open-source app launcher for RP2040 based devices2025 · github.com · ▲154

  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…

  gpudeploy.com – "Airbnb" for GPUs2024 · gpudeploy.com · ▲267

  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.…

  Llama 3.1 70B on a single RTX 3090 via NVMe-to-GPU bypassing the CPUFeb 2026 · github.com · ▲395

  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

  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.

  Icepi Zero – The FPGA Raspberry Pi Zero Equivalent2025 · github.com · ▲233

  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.…
