A mining-analytics hub, honestly counted

Over the last stretch I’ve been building a set of small, independent mining-analytics tools — each one its own browser app, its own repo, its own data — and the moment there was more than a handful, I needed a way to see them as a whole. That’s Faena: a single open launcher that catalogues the tools across the value chain (exploration → drill & blast → load/haul → comminution → processing → tailings → asset health → economics) and links out to each one. It doesn’t bundle or run anything; it lists and links.

The design decision I care about is the counting. It would be easy — and dishonest — to say “39 mining apps.” So the registry that drives the whole site carries a lifecycle on every tile, and the site shows it:

I like this because it makes the roadmap a feature instead of a fib. A visitor sees at a glance the few things that actually work today and the many that are in progress or planned, and no single tool gets to oversell itself under the cover of a big number. It’s the same discipline I’ve been applying tool by tool: ChargeCascade says out loud that its 3D is a kinematic view, not a DEM run, and that its data is synthetic-but-realistic; RotorVitals shows where its deep model loses to plain physics rather than hiding it behind an accuracy number.

The two that reached the bar this round are worth a line each. ChargeCascade turns the scattered comminution equations — critical speed, the Davis regime, Hogg-Fuerstenau/Morrell/Bond power — into one live, tunable studio, with a thin ONNX layer for speed and a sanity guard that never gets to overrule the exact engine. RotorVitals grew from bearing envelope analysis into a full condition-monitoring-and-prognostics workbench on real measured vibration, with a four-model remaining-useful-life ladder benchmarked over 36 real run-to-failure trajectories.

None of this is the flashiest way to present a portfolio. A catalogue that admits most of itself is still a plan is less impressive than “39 apps.” But it’s the version I’d actually stand behind, and the honest count is the point — the hub is only useful if you can trust what the tiles say.
