The Project:

 

A ceiling surface that adapts itself the current acoustic conditions of the room. The surface changes shape, orientation, and porosity based on the frequency, location and intensity of the sound waves occupying the space. The transformation is free form in the sense that there are not presets for a lecture or a social event instead the surface responds in real time to an average of acoustical data collected over the past minute.

Eyes in a box

Posted in 8. Finite State Machines on October 27, 2009 by Frank Scarola

So i made myself a pet… box… with eyes.  Named him “Eyes” (already have a pet box named Box). Eyes is a nice pet, lots of fun to play with, but only at night, he’s nocturnal you see…

Eyes has three states, sleeping, awake, and alarmed. A photo sensor on the exterior of the box tells eyes to come out and play, or hide while an infrared sensor tells him if someone gets too close.

sleep – everything off, light sensing only

awake- green leds (eyes) on blinking at a random interval

alarmed – “eyes” open and a blue led to shine a light on the object in range
