Dome Cam

The DomeCam uses 180 degree servo motors to sweep a video cameras field of view through 360 degrees to provide a view of a complete hemisphere.
These are test programs I wrote to demo the possibilities at a recent DorkbotPdx meeting. The first directs an Arduino to scan the horizon on a 10 second cycle. The second rights the resulting video with QuartzComposer patches. 

  #include <Servo.h> 

  Servo x, y;  

  void setup() { 
    x.attach(9); 
    y.attach(10); 
  }

  int period = 10; 
  float scale = 2 * 3.141592 / (period * 1000); 

  void loop() { 
    float t = millis()*scale; 
    x.write(80*(1+sin(t))); 
    y.write(80*(1+cos(t))); 
    delay(15); 
  }

Look here for movies soon.
