Show HN: Pentaton LP – a music streamer with an LP sleeve sized display Hey HN! I always liked to see and touch the cover artwork of the CDs and LPs I bought in the past, but in the end the convenience of digital streaming won me over and I accepted no (or stamp-sized) artwork. Lately I’ve been missing this more and more and ultimately decided to try to do something about it. So I built a streamer from the ground up.<p>Happy to answer any questions, this is my first PCB design and 3D model all in one project.

Show HN: Self-hosted voice AI agent for Asterisk/FreePBX Hi HN folks ! I am the author of AVA, a self hosted AI Voice Agent that plugs into Asterisk&#x2F;Freepbx so you own all the aspects of an AI Voice agent in your own infrastructure. It uses Asterisk native Audiosocket&#x2F;RTP with python engine to run STT,LLM and TTS loop. The project support several full providers openai, gemini, grok, elevenlabs out of the box and also provides options to build custom pipelines by choosing different stt tts and llm.<p>It also supports full local agent if you have a GPU with 25GB RAM which enables realtime conversation along with tool calling.<p>I started this as a hobby project last year when I started exploring voice agents and every saw every Saas tried to lock you in their eco system. Since then project has taken off and a lot of asterisk people started using it due to ease of setup and wide range of providers and flexibility.<p>Core is MIT: <a href="https:&#x2F;&#x2F;github.com&#x2F;hkjarral&#x2F;AVA-AI-Voice-Agent-for-Asterisk" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;hkjarral&#x2F;AVA-AI-Voice-Agent-for-Asterisk</a> Free and open source forever.<p>No install Mock UI us hosted at: <a href="https:&#x2F;&#x2F;demo.agent6789.com" rel="nofollow">https:&#x2F;&#x2F;demo.agent6789.com</a><p>I am also exploring to convert this into a more polished version for Operators to handle multiple customer and multi tenant environment and I would genuinely like to hear feedback on it.<p>Happy to answer any questions and gather any feedback. Thanks.

Show HN: Juggler – an open-source GUI coding agent, by the creator of JUCE Hello HN, I don&#x27;t post on here much, but wanted to get some eyes on a new project I&#x27;m just launching. I think we definitely need one more AI code agent..<p>I&#x27;m a long-term C++ dev, and over 30+ years I&#x27;ve created some successful audio dev tools (JUCE, the Tracktion DAW, the Cmajor DSP language). All of these came from me getting annoyed with something I had to use, and deciding to have a go at my own take on whatever it was.<p>So Juggler is my attempt at an AI code agent, after spending too many hours loving what the models could do, but hating the CLI experience, and having some opinions of what a better UX might be for this stuff.<p>Lots more blurb on the website and github, but a quick tech dump which might grab your attention if you&#x27;re into these things:<p>A session is a document, not a log file. Each conversation is a Yjs CRDT tree. It can branch into sub-threads (recursively), and you can drill down, backtrack, edit, undo&#x2F;redo, and inspect everything: tool calls, approvals, and the raw context JSON going to the model, etc. The UI is based around Finder-style Miller columns rather than a big doom-scroll, and is quick to navigate.<p>Because it&#x27;s a CRDT behind a local web server, multiple clients can attach P2P to a live session: the native desktop app, a browser tab, or your phone. Run the headless server on the box where the code lives, view it from wherever.<p>Almost everything is a JavaScript plugin: every item in the context (read&#x2F;write&#x2F;bash&#x2F;etc.), the LLM loop strategies, slash commands, and their UIs. You can inspect, fork, or replace any of them. I don&#x27;t do much agent customisation myself, but lots of people do, and I&#x27;d love to see what they think of with this plugin API.<p>Go backend, Wails for windowing (no Electron), plain type-checked JS (strict JSDoc), Yjs for the documents. Usual BYOK provider support: Claude (CLI or API), OpenAI&#x2F;Codex, Gemini, Ollama, OpenRouter, DeepSeek, etc.<p>The app&#x27;s AGPLv3; the extension SDK and bundled extensions are Apache-2.0, so extensions have no copyleft strings attached. No signup, no telemetry, trying to make it frictionless for people to try it out..<p>It&#x27;s very much a beta, and is a one-man side project. It hasn&#x27;t yet had a proper kicking from the real world, but I&#x27;m confident some people with similar preferences to my own will like it!<p><a href="https:&#x2F;&#x2F;juggler.studio" rel="nofollow">https:&#x2F;&#x2F;juggler.studio</a>

Claude Code sends 33k tokens before reading the prompt; OpenCode sends 7k This started based off of a hunch. We usually use OpenCode, but were &#x27;forced&#x27; to use Claude Code for a while due to issues with Meridian. In that time, we saw the usage meter rise much, much more quickly than when using OpenCode.<p>This was the initial anecdotal evidence, but we undertook this small study to collect empirical data:<p>We added logging between the agentic coding tool (Claude Code and OpenCode) and Anthropic&#x27;s endpoint, and captured all requests (and the returned usage blocks).<p>With one caveat (toward the end of the post) we found unambiguously that Claude Code was far more inefficient in terms of its cache strategy and its harness token usage than OpenCode.
