There are plenty of underwater sports cameras available, but they can be quite expensive, especially if you want to control them remotely. In this tutorial we’re going to use readily available Pi add-ons to make a cheaper, customisable camera unit. There are lots of options and alternative sources of components for a project like this. For example, the Pimoroni Enviro pHAT is a really useful option that can report back information about the environment in which the camera is operating, especially how much light is available. There’s a fair bit of software configuration involved, but example config files are in the GitHub repo for this article.
