Apparently not satisfied with Arduino’s delay() function, Flickr member namaRyo is working on an microcontroller monitored sandglass timer. The Arduino uses an optical interrupter to detect when sand falls through the glass. Once it determines the sand has run out, a servo motor is activated, flipping the sandglass over and resetting it.
An interesting combination of digital and (very) analog technology … but beyond conceptual art, anyone have a guess as to practical application?
