Products that do what BuildHiFi – PC Part Picker for Home Stereos does
I've been building hi-fi stereo setups for years with all sorts different budgets, different rooms, helping friends spec out systems. I even worked at a hi-fi shop for several months before I came scurrying back to tech (a good story, but, uh, out of scope here). I kept wishing for something like PCPartPicker.com but for stereo gear. A place to design and save my systems, check compatibility, and see exactly how everything works. So I built it. No sign-in required to create builds: just hit "Start Your Build" and add parts. The signal chain diagram updates in real-time as you build and you…

Hi guys, I want to show you a site I built, which lets you build your own virtual world of soundscape. I work out of cafes all the time because the white noise and ambience helps me concentrate well. Then one day I wondered: what if I could have my own cafe on my laptop, so I can enjoy that state of mind anytime, anywhere? And what if I can share it, so other people can enjoy that emotion too? So I built Daydream. It lets you create your own world of soundscape, by combining visual, sound samples, and music. Once you set it up, you can just use it as an ambience player, or a music player…

Hey all. For the last few years, I have been developing a software synthesizer as a side project. It's taken longer than I both hoped and feared, but earlier this week I finally shipped 1.0. Details about the synth itself are up on my website, https://lhiaudio.com/. For those who are unfamiliar, in music production, there are host applications (such as Logic Pro, Ableton Live, or REAPER) in which most of the work (such as recording or sequencing MIDI data) is done. These applications generally have some built-in tools for the actual generation and processing of audio data, but…

Last week I released a web-based, automated build environment / Makefile generator for FPGA projects: http://www.boldport.com It's just a start, and I'd appreciate feedback. Tell me what sucks about it, what you love, where to improve. (BTW, I'm happy to help anyone who's interested to set up or convert their projects to work with the "boldport flow"!) In this context, my proposal for a scalable and version control friendly project structure for FPGA designs may be interesting as well: https://www.boldport.com/docs/fpgaproj

I used to watch hundreds of hours of lofi beats on youtube while I was coding, but I got really sick of all the ads. I decided to build a better alternative - It's a configurable space for you to hang out online while you work, with a ton of relaxing music and backgrounds. Its got useful tools built in like a timer to keep track of how long you've been locked in, and a notepad for todos or scribbling down ideas while you work. Honestly this is the first tool I've built that I personally use every day, so I'm hoping some of you out there can get some use out of it too!

Just wanted to make my first post about something interesting I've been working on for some time. Any ideas/suggestions for new hardware or software I should try out are welcome, though I will only have time for a major overhaul in a month or two where I want to redo and document everything a bit better than how it is currently. Hope this can inspire someone to start their own homelab or give some ideas to already existing ones!

Hi HN, I am a solopreneur in the evenings and a software engineer during the day. In the past, I have created lots of calculators for my web projects and freelancing friends. These were pretty basic, but users always welcomed them. I also used currently available builders, but the problem was that they were either slow, broke on mobile devices, had nonsense page view limits, or were expensive. Some even ticked all those boxes. So I have decided to create my own, with a simple interface, and called it Creative Widgets (if it ever takes off, I plan to add more exciting stuff like charts, etc,…

Hey HN, After GPT-3 created waves in the tech industry, a lot of AI tools were emerging and with that, some AI website builders But the results seemed way too generic to us. It felt like the developers were rushing to catch the wave instead of building a proper tool We took our time, did months of RnD and finally came up with something better than what others in the market are doing. It’s got better design output. While it’s still in beta, I wanted to show HN what we did. Will appreciate the feedback when you guys try it out. Here is the link to signup for the beta:…

Hey HN, I'm a student shipping projects on my nights & weekends (today is no other) Music is a huge aspect of my life. I appreciate tons of artists and constantly search for a new way to experience it. Then something catches my eye... An iPod. This seemed like a perfect way to have fun while listening to music + the added mindfulness of intentionally selecting an album. Sadly, it's a no go in 2025. Lack of Bluetooth, Spotify sync and high prices was a deal-breaker for me. That's why I decided to build an iPod player for your desktop. Yup, you heard it right. From the prototype as I was just…

We did a "Show HN post" 6 months back of our startup and we're very excited to show everyone how far we've come as well as the lessons we've learnt so far! It's been a roller-coaster so far and we think there's lot more of the same to come! We did apply for Ycombinator funding but got turned down :( But may re-apply soon :) For those that don't know, our startup is called Scirra and we make Construct 2 which is an HTML5 game engine (http://www.scirra.com). Our engine allows anyone to make HTML5 games without knowing any programming. It's only me and my brother working on this and we're based…

I designed and built a studio-quality electret microphone preamp focused on low noise, high gain, and clean audio capture using easily available components. This is an original design — it does not follow TI, Analog Devices, or other common application schematics. The circuit was tested and verified in LTspice before building. All schematics, design rationale, and build instructions are open-sourced for anyone to replicate or improve. Here's a short demo of the audio performance: https://youtu.be/RZR_PrxcBBU?si=9gN_5yx09bwNFjba I spent over a month researching, simulating, and…

Hey y'all, So - the main idea of this is to make a WebAudio synthesis/sequencer tool which humans can use via the UI, but where the big unlock is for agents to drive with MCP It's semi decent as "make a groovy jazz track", especially for retro sounds - but the real use case is more like "make a jetpack whoosh effect I can control via code at runtime - where the sound changes based on character health or how much fuel is left" In other words, the target audience is not musicians (except maybe of the Max/MSP sort), but more like creative coders who want to shape the sound iteratively…

I am a product designer by profession, and recently, I ventured into coding and started developing applications. Today, I'm excited to share a project I've been passionately working on. The concept is a voice-activated journal: just voice-record your thoughts, and the app will transcribe them into text. I built this to help those like me who struggle to build a journaling habit. Also has features that encourage habbit building like a streak/tracker and a threshold marker encouraging you to record a minimum amount. I used OpneAI Whisper to power the transcriptions which means you can…

Hey everyone, I built a Sonic Pi MCP to create music with just prompts and jam with Claude I've linked a demo of me asking Claude for a rock beat, and then for some D minor chords that sound like Pink Floyd Let me know what you think!

Hi HN, I’ve been working on an AI-powered website builder that allows anyone to create a fully functional website in just a few minutes. No coding, no design skills—just a simple, intuitive process with AI handling the heavy lifting. Here’s what you can do with it: • Create a website by entering a name, description, and subdomain. • Use AI to design the site, customize content, and edit sections with simple prompts. • Preview, tweak, and publish your website live instantly. • Download the code for full flexibility if you want to self-host or integrate. It’s still an MVP, and I’ve got lots of…

Hey HN. I built an AI agent harness over the past few months and I'm open sourcing it today. Some context on why. I've been building with Claude Code daily using this harness. It orchestrates multiple AI agents as a team, with a dashboard, chat, kanban board, the works. I used it to build a full SaaS product (MyUpMonitor, https://myupmonitor.com) in about 24 hours of focused coding. Then yesterday Anthropic announced Mythos and decided to keep it behind closed doors. Meanwhile I'm paying for Claude and I can't access their best model. I don't think that is nice at all... So I'm…

Hey yall, I built this for my makerspace. We wanted to let each other borrow things, but also didn't want to put up a big shiny sign saying "hey everyone, my garage has a super fancy oscilloscope just sitting there" and also didn't want to necessarily always need to say yes to everything. However, when I show it to people, they've been suggesting using it for other things like board games, or wedding equipment, etc. I'm still trying to find PMF, so please let me know what you think! For the stack, it's all Elixir + LiveView which is really nice, and then Fly.io, Fly's MPG, Tigris Data,…

Hey HN! Last week I was working on a website and needed a way to synchronise visuals with live music. I've used MIDI controllers for this before, but I am travelling right now and don't have mine with me. So I had the crazy idea to build a browser extension that uses the keyboard as input and includes a sequencer. I gave myself 24 to work on it. It ended up taking longer (of course), specially since I ended up creating a demo, a small landing, docs, and an intro video. Took me one week from idea to launch (pushed quite a bit tbh). Features: - Works as a browser extension. Atm distributed…

Hey HN - We're building wispbit (https://wispbit.com/) - a tool that lets you build your own AI code reviewer. We built this because we worked in big and complex codebases where we kept hitting booby traps - often the same ones. People forgot things, or quit altogether, amplifying the problem. We looked for other ways to fix this, but the solution is usually a combination of: - Writing a linter rule - too difficult and time consuming. - Writing docs and having frequent meetings on alignment - basically a full time job. - Using plug and play code reviewers - too generic and…

Hi HN, I’m Akshay. I built AMP because I was tired of my AI agents having "amnesia" the moment I closed the terminal. Like many of you, I use Claude/Cursor daily. RAG is great for searching documentation, but it’s terrible for continuity. It chunks text blindly, losing the narrative. When I asked my agent "Why did we decide to use FastAPI last week?", it would hallucinate or just give me generic pros/cons because the specific context of our decision was lost in a vector soup. So I decided to build a proper *Hippocampus* for my agents. *What is it?* AMP is a local-first memory…
