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 Ethio

A Digital Twin of my coffee roaster that runs in the browser is positioned in show hn launch, a segment that rewards a clear, focused offering.

Its current recorded stage is Show HN launch.
