This project, courtesy of [fbz] brings back memories. Xeyes is one of those classic apps – handy for testing out connections and great for screwing with new people who had wide open servers. [Zn000h] built this set of mechanical Xeyes – instead of following a mouse, it samples video and follows the highest contrasting moving object around. (See the description for more on the video filter) The data is passed on via USB to a set of ATTINY controlled servo operated eyes. Just in case the server can’t handle the load, you can find pictures of the setup here.
