Andy Holtin, Assistant Professor of Sculpture at American University, in Washington DC, just posted an in-progress video of an installation project he’s working on called Glance. He writes:
I’m using the audio line from the DVD to sync eye movement with the Arduino (used the Pro Mini this time and loved it) through an opto-coupler as input. Physically fun, too — used casting processes to copy some gears, and etched my own PCBs for the first time. Maybe I will do a build blog for this one.
Note to Andy: Please do! [Thanks, Alberto!]
