In 2017 these three posters were commissioned by the University of Wisconsin IoT Research Lab to demonstrate concepts of Internet of Things security. The three posters demonstrate 1) security vulnerabilities associated with sensors, and how a hack at each level of the chain might impact sensor data 2) security vulnerabilities with controllers, and how hacking any level can have an impact on door locks, HVAC units, or other devices, and 3) the broad impact of a compromised device and how multiple compromised devices can be used to attack assets on the Internet.
I built everything myself, including the design of all the 3D printed parts, the design of the poster, and the firmware running on a Raspberry Pi.
