My dad loves birds. So last November, we installed a microphone attached to a @raspberrypi.com with a bird sound classifier in our small garden in Heidelberg, Germany.

Remote sensors pick up light that is not visible to the human eye. If we map them to visible channels, we see things we would otherwise not see. These two images from NASA's satellite program Landsat show Los Angeles and its surrounding area in January 2024 and in January 2025.
