The Steampunk Eyeball is a table-top device, that “watches” me as I walk around during a presentation. It uses the color-object tracking capability of the CMU Pixy camera to activate servos, causing the eye to follow a brightly colored piece of clothing I’m wearing. Here’s a demo.
“Dynamic Conference Audience Visualization and Presentation Apparatus” Camera
This is the Logitech C310 Web cam, modded into a brass Steampunk-styled frame. The contraption attaches to a Raspberry Pi and is used to project small micro-controller boards up onto large presentation screens. I use the apparatus during my tech presentations. The device works great on the Pi, along with my LibreOffice slides. It’s easy to switch between the camera and slides, via the wireless keyboard/mouse pad.
