Show HN: Willow – Open-source privacy-focused voice assistant hardware

As the Home Assistant project says, it's the year of voice!<p>I love Home Assistant and I've always thought the ESP BOX[0] hardware is cool. I finally got around to starting a project to use the ESP BOX hardware with Home Assistant and other platforms. Why?<p>- It's actually "Alexa/Echo competitive". Wake word detection, voice activity detection, echo cancellation, automatic gain control, and high quality audio for $50 means with Willow and the support of Home Assistant there are no compromises on looks, quality, accuracy, speed, and cost.<p>- It's cheap. With a touch LCD display, dual microphones, speaker, enclosure, buttons, etc it can be bought today for $50 all-in.<p>- It's ready to go. Take it out of the box, flash with Willow, put it somewhere.<p>- It's not creepy. Voice is either sent to a self-hosted inference server or commands are recognized locally on the ESP BOX.<p>- It doesn't hassle or try to sell you. If I hear "Did you know?" one more time from Alexa I think I'm going to lose it.<p>- It's open source.<p>- It's capable. This is the first "release" of Willow and I don't think we've even begun scratching the surface of what the hardware and software components are capable of.<p>- It can integrate with anything. Simple on the wire format - speech output text is sent via HTTP POST to whatever URI you configure. Send it anywhere, and do anything!<p>- It still does cool maker stuff. With 16 GPIOs exposed on the back of the enclosure there are all kinds of interesting possibilities.<p>This is the first (and VERY early) release but we're really interested to hear what HN thinks!<p>[0] - <a href="https://github.com/espressif/esp-box">https://github.com/espressif/esp-box</a>

Show HN: WhyBot, making GPT-4 question itself

Hi HN — we’re John and Vish! We built WhyBot, a tool to help you deeply explore a question or topic. You ask a question, and WhyBot responds by building an ever-expanding knowledge graph. It does this by recursively generating answers and follow-up questions. You can change its persona to change the flavor of the generations (try toddler mode!).<p>We originally built this for the AngelList Agent Hackathon (<a href="https://twitter.com/AqeelMeetsWorld/status/1650279974405042178?s=20" rel="nofollow">https://twitter.com/AqeelMeetsWorld/status/16502799744050421...</a>) and got a lot of interest from folks asking to play around with it. So we thought it’d be fun to brush it up and release it as a web app! It’s a work in progress and we plan on adding more features, such as saving, sharing, focusing on one branch and potentially executing code.<p>We hope you enjoy playing around with it and would love to hear any of your feedback or thoughts.

Show HN: React.js LLM Agent (open-source)

I've been working in the couple of months on an experiment, trying to make GPT-4 much more useful for web development / React, writing production code that is relevant to any repository without copy pasta from ChatGPT or having small snippets of auto-complete from Copilot that are not in your context.<p>The agent is taking a user story text and generating and composing multiple react components to generate the relevant screens, based on atomic design principles, with Typescript, TailwindCSS and RadixUI.<p>Is is still experimental but very interesting results, I would like to get your feedback on it! It is completely open-sourced, looking for contributors!

Show HN: Kaizen, music updated over time like software

Hi, I'm co-founder and CTO of Kaizen.<p>The project started as just a weekend project with me and a music producer friend. It has since grown into a community of artists looking to share their music more frequently and engage with their fans more consistently.<p>We've just launched on ProductHunt: <a href="https://www.producthunt.com/posts/kaizen-3" rel="nofollow">https://www.producthunt.com/posts/kaizen-3</a><p>We would love any thoughts or feedback!

Show HN: Infinity Whiteboard, Designed for Teachers

I've created a whiteboard which I use every lesson when teaching maths, though it can be used for anything. It currently has a few hundred teachers using it daily. It's designed for use with touch-screen interactive whiteboards in classrooms, and stays in sync with your phone/tablet/whatever without signup/login.<p>You can also find me on Twitter where I post updates etc: <a href="https://twitter.com/jakegmaths" rel="nofollow">https://twitter.com/jakegmaths</a><p>Some features and cool things:<p><pre><code> * Sync devices without signup - offline by default, just hit 'sync devices' and use the same code on multiple devices to sync * Touch-first - 1 finger draws; 2 finger pan/zoom; 3 finger gestures like changing pen colour * Add images - when teaching, this is usually photos of student work taken on my phone and auto-sync'd to the whiteboard at the front of the room * Add PDFs - when teaching, these are usually past paper exams which I then annotate over with the class * Zen mode - 3 finger tap or hit the ∞ icon to hide the UI; something I use every lesson so students can focus on the actual maths (there's also a fullscreen button when not on iOS) * Visualiser - often when teaching we'll work on paper with a webcam aka 'visualiser' pointing down at it; this projects that to the main whiteboard, with optional cropping, freeze-frame and snapshots * Screencast - many teachers use eg PowerPoint to teach; instead, I'll use PowerPoint in edit/design mode rather than slideshow mode, with a locally-cast cropped portion of that on the main whiteboard at the front of the room. This enables me to eg edit my PowerPoint as I go and use all the PowerPoint tools not available in slideshow mode * Instant replay - hit the play button to play back all the scribblings currently showing on the screen * Magnet mode - when sync'd with another device, use the magnet icon so the other device follows you. Most of my teaching is now via a tablet-with-stylus anywhere in the room, and as I pan/zoom around with the tablet the main whiteboard comes with me... but only when I want it to by activating the magnet * Student mini-whiteboards (MWBs) - if my students have devices and I want them to use them, I 'sync devices' then enable student MWBs and each student has a live copy of the whiteboard, and I can see what they write and can showcase any student instantly on the main board * PWA support - install as a PWA and you can download whiteboards as .iwb files which can then be double-clicked to open/edit on desktop * Free - I have no plans to charge for this </code></pre> Other things you may find interesting from a tech perspective:<p><pre><code> * The client is a single <5,000 lines HTML file, with JS, CSS, SVG-favicon all inlined (plus PDF.js lazily loaded if you add a PDF) * This is vanilla Javascript with no frameworks or libraries (except PDF.js) and no minification or build scripts - just view-source and check out how ugly all my code is! * 77.6kB for everything (except PDF support)... the size of 'modern' websites frankly disgusts me * The server is just a single ~500 line Javascript file and runs on Deno (also ported to Bun but unstable for now) and really just serves some static files, deals with websockets and temporarily stores images people add * Costs ~£5/month on Heroku * There's no database or any long-term persistence - Heroku servers restart every 24h and nothing is saved beyond that; it's all ephemeral</code></pre>
