# Original prototypes

The original prototypes (Mk1) of the Light Tunnel and Wind Tunnel were presented in an [open-access paper](https://www.nature.com/articles/s42256-024-00964-x) in Nature Machine Intelligence, together with their open-source [blueprints](https://github.com/juangamella/causal-chamber/tree/main/hardware) and a collection of [public datasets](https://github.com/juangamella/causal-chamber).

The chambers available through the [Remote Lab](https://docs.causalchamber.ai/remote-lab/quickstart) correspond to the new models (Mk2) of these chambers. They offer more variables than the original Mk1 prototypes used to collect many datasets in the [dataset repository](https://github.com/juangamella/causal-chamber). To make it easier to replicate experiments from the repository, we provide a mapping between the old and new variables.
