Many of us have old phones or tablets sitting in a drawer at home. They might have a dead battery or broken screen that keep us from using them, but in theory they are still quite functional computers. Imagine if we could install a new operating system and make them useful for new purposes: a tiny web site, small home server, media player, sensor station or even stranger, more poetic things. Thanks to efforts like PostmarketOS this is possible, but it can be intimidating and confusing.

In this workshop, we will attempt to install the Linux-based PostmarketOS on "obsolete" Android devices and find convivial new uses for them.

Networks of high-quality ground-based GNSS stations provide maps of ionospheric total electron content to correct these errors, but large spatiotemporal gaps in data from these stations mean that these maps may contain errors. Here we demonstrate that a distributed network of noisy sensors—in the form of millions of Android phones—can fill in many of these gaps and double the measurement coverage, providing an accurate picture of the ionosphere in areas of the world underserved by conventional infrastructure. […] This work demonstrates the potential of using a large distributed network of smartphones as a powerful scientific instrument for monitoring Earth.

This guide explains everything you need to know to build stand-alone photovoltaic systems that can power almost anything you want.

Billions of phones will be hoarded in drawers and cupboards or thrown away rather than recycled, studies suggest.
