The Scream Detector and digital photo frame, a photo by geekphysical on Flickr.
We were invited to participate in a gallery opening in Sweden. The theme was a 20 by 20 cm canvas interpretation of Edvard Munchs “The Scream”.
I hacked a digital photo frame I found. Put a picture of The Scream on it and mounted the screen and electronics in a 20 by 20 cm. frame.
I located the wires for the backlight of the LCD and put a FET on it.
I used the song detector project as the basis to make a scream detector that in term controlled the backlight via the FET.
This way you have to scream to see the scream…
