Show HN: Gifup – GIF tools that run in the browser (ffmpeg.wasm) Hi HN. GIFUP was an avatar and glitter generator I ran from 2007; it made about 1.3M animations before the web moved on. This year I rebuilt the domain as a set of GIF tools where the encoding happens in the tab via ffmpeg.wasm: video to GIF, compress, resize, crop, captions, GIF to MP4, plus presets that fit Discord, Slack, Twitch and WhatsApp limits. Nothing is uploaded. The file is read from disk, FFmpeg runs in WebAssembly, and the result is handed back as a blob. The engine is about 10 MB compressed, fetched once and cached. The core is single-threaded because the threaded build needs COOP/COEP headers, so a 10-second 720p clip takes a few seconds rather than a fraction of one. No size caps, no queue, no account. Two optional server features: "Get a link" hosts a finished file if you want to paste it in a forum, and a WhatsApp sticker page can deliver a sticker to your phone. Both are off until you press th...

Show HN: Hob - Open-source, on device alternative to Claude Cowork and ChatGPT Hey HN, I'm Christian and this is a new OSS project I've been noodling on for the last couple of weeks. Hob is a free, MIT-licensed desktop app for Mac, Windows and Linux that works on your files the way the Claude and ChatGPT desktop apps do, except the model runs on your own computer. It uses open-weight models (currently Gemma 4 and gpt-oss). All your chats and files never leave your system. The only things that go online are web search (can be turned off in settings) and any MCP connectors you add yourself. Main features: - Automatically finds the best open-weight model for your hardware on first install (Mac/Linux/Windows) - Writes sandboxed Python code for ad hoc tools (data processing, document conversion, graphs etc.) - Built-in web search (powered by SearXNG) - MCP support - Image recognition - CRUD to your local filesystem - Works fully offline with no internet Before building this I tried ...

Show HN: RPI Pico (RP2040) PIO Emulator Package for Go I have been developing a bus communication protocol for a while using the Raspberry Pi Pico (RP2040)'s programmable IO (PIO) hardware (basically- 8 tiny processors that run assembly programs to manipulate GPIO pins) and I needed some way of testing my programs, as the real hardware is undebuggable. Unfortunately, none of the existing emulators I could find supported connecting multiple RP2040s together, and they each had a few different missing bits of functionality, so I decided to make my own! My emulator supports running multiple RP2040s electrically connected together, and emulates the whole of their PIO blocks (all 8 processors each), along with all of the more niche inter-processor interactions and GPIO functionality I could possibly find in the datasheet. I built it as a Go package so that it can be used inside of other programs; I intend on using it myself inside a test suite against my in-development protocol. I've...

Show HN: Hurston-1 open source TTS that speak Southern American and Afro-English Hey HN, I’m open sourcing my Hurston-1 narrowband TTS model (Apache-2.0). It is very good with American English and does especially well with Southern American and Regional African English accents. Destined AI is based in Atlanta, and I built this because I’m amazed by what AI can do, and I wanted to help introduce and welcome more people to feel comfortable using and interacting with AI. Since 2021, I’ve been collecting fully consented voice data from over 20,000 people, 1M audio recordings, and over 1,800 hrs of audio captured to date. For this model, I used a small part of the data, 136 hrs, to finetune Maya1 and expand it’s capabilities. Hurston-1 is a narrowband TTS model that focuses the output on telephone use because that is still where most of these voices will be heard. I’ve used it to support customers such as Amazon and Salesforce and generated over half-mill revenue with it. Now I’m open sourc...
