I helped make cheap cameras that continuously monitor wildlife.
Zoonotic infections in humans originate in wild animals. To better understand their contact structure, I have been developing an open source hardware and software kit for monitoring wild animal behaviour using the Raspberry Pi, Python, and 3D printing. The time-lapse cameras, which we call TikiCams (they look like Hawaiian lamps when mounted), are based on off-the-shelf hardware available at computer and hardware stores.
