We designed this open-source hardware platform to be easily reconfigurable to a range of materials and form factors. To test this flexibility of the principles of construction and operation of the environmental chamber, we report the original hardware design suitable for testing bare thin films, and also three subsequent equipment modifications, including adaptations to study either perovskite devices or bulk crystals. Two of these modifications occurred in different laboratories. We report key learnings from this technology translation process with the goal of defining a set of best practices for open hardware reporting. We observe that open hardware is common for foundational chemical tasks (i.e., liquid handling - ) but has been slower to realize for more specialized tasks like stability testing. Ideally, sharing these learnings may expedite the processes of creating and adapting future specialized open hardware.
