Collaborated w/ Ziv, Alex, Jorge, and Kristina.

Long long time ago(Oct, 2013), Ziv came out of an idea for the photo booth of ITP Halloween party–> Photoboo, which is using strong light to frighten whoever walk in and taking pictures of them. Big success.

I was responsible for the light part and came out of an idea that just using the external flashlight kit of Canon 5D. With this reference, flashlight worked like a charm with a simple button(P.s. We used transistor instead of optoisolator).

Connected to the complicated Max/MSP patch Alex made, the flashlight triggered once infrared sensor detecting people approaching.

Here’s the simple circuit.

And here’s the code for Arduino.

#define CAMERA_FLASH_PIN 8
#define BUTTOM_PIN 2

void setup()
{
  pinMode(BUTTOM_PIN, INPUT);
  pinMode(CAMERA_FLASH_PIN, OUTPUT);
  digitalWrite(CAMERA_FLASH_PIN, LOW);
  Serial.begin(9600); // open serial
  Serial.println("Press the button to trigger the flash");
}

void loop()
{
  if (digitalRead(BUTTOM_PIN) == HIGH) {
    digitalWrite(CAMERA_FLASH_PIN, HIGH);
    delay(100);
    digitalWrite(CAMERA_FLASH_PIN, LOW);
  }
  else {
    digitalWrite(CAMERA_FLASH_PIN, LOW);

    Serial.println("Press the button to trigger the flash");
  }
}

And…. I also designed some frames for the Photoboo!

Happy time 😀
