Show HN: A Digital Twin of my coffee roaster that runs in the browser (❄️ Score: 150+ in 6 days)
Link: https://readhacker.news/s/6D4Ki
Comments: https://readhacker.news/c/6D4Ki
I built this website to host a data-driven model of my coffee sample roaster.
I realized after 20 or so batches on the machine that while the controls are intuitive (heat, fan, and drum speeds), the physics can be unintuitive. I wanted to use my historical roast data to create and tune a model that I could use to do roast planning, control, and to help me build my own intuition for roasting. This website lets you interact with my roaster in a virtual, risk-free setting!
The models are custom Machine Learning modules that honor roaster physics and bean physics (this is not GPT/transformer-based). Buncha math.
The models are trained on about a dozen real roasts. The default bean model is an Ethiopian Guji bean.
My next steps are to add other roasters and the ability to practice control/reference tracking.

Show HN: I built a simple ambient sound app with no ads or subscriptions (Score: 154+ in 14 hours)
Link: https://readhacker.news/s/6DrCD
Comments: https://readhacker.news/c/6DrCD
I’ve always liked having background noise while working or falling asleep, but I got frustrated that most “white noise” or ambient sound apps are either paywalled, stuffed with ads, or try to upsell subscriptions for basic features.
So I made Ambi, a small iOS app with a clean interface and a set of freely available ambient sounds — rain, waves, wind, birds, that sort of thing. You can mix them, adjust volume levels, and just let it play all night or while you work. Everything works offline and there are no hidden catches.
It’s something I built for myself first, but I figured others might find it useful too.
Feedback, bugs, and suggestions are all welcome.
