idle hands

My friend Emmy wanted an exhibition at her gallery ItchySoul Atelje in Malmö so she asked her friends to make a rendition of Edward Munch's "the scream"
She handed out canvases  20 by 20 cm in size and we all started to work on it. The Vernissage has alredy been so I thought I'd share what I did here.

First of, I'm no master painter, I used sharpies and duct tape. I wanted to make something more robotic with straight edges. And I wanted the robot to scream. A little like the death-screams of a portal gun-tower. For this I used a attiny 13v, two leds, a speaker, asome batteries and a little code. It does scream at uneven intervals. It's all based on the tiny arduino loader, so it was pretty easy to code.
