HardFaultHandler

What it does

HF·NODE puts AI on your bench. It knows when your board is wedged vs. dead, catches power conflicts your firmware can't see, and reflashes bricked targets over the debug port — so your coding agent can run embedded dev unattended. External debug device for embedded boards — no SDK, no code changes. Watch GPIO, ADC and power rails, read CPU and register state, track device life state, catch firmware that runs wrong without crashing, and push OTA with rollback from anywhere.

HF·NODE is an AI hardware debugging agent: it watches your target

"The most important log line is the one your AI never got to read." When your board goes quiet at 3am — your AI already knows whether it's dead or wedged. Until now, an agent debugging embedded hardware was working blind: it could write code, flash it, and then guess. HF·NODE gives AI a body on the bench — power rail, serial, debug port, GPIO — so it can observe, diagnose, recover, and try again. Overnight. Without you. No SDK. No code changes. No engineer sitting next to the board.

  I kept missing when my Codex agents finished, so I built relayd — a mobile dashboard that sends push notifications and lets me continue agents from my phone. Free tier available. Would love feedback.

  openai-realtime-embedded-SDK Build AI assistants on microcontrollers2024 · github.com · ▲63

  Hi HN! This is an SDK for ESP32s (microcontrollers) that runs against OpenAI's new WebRTC service [0] My hope is that people can easily add AI to lots of 'real' devices. Wearable devices, speakers around the house, toys etc... You don't have to write any code, just buy a device and set some env variables. If you have any feedback/questions I would love to hear! I hope this kicks off a generation of new interesting devices. If you aren't familiar with WebRTC it can do some magical things. Check out WebRTC for the Curious[1] and would love to talk about all the cool things that does also.…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
