This painting mimics what you might see in a bright night sky: mostly static lights, with an occasional shooting star. The lights are programmed with a fading pattern (always (repeat 4 (wait 90)) (right 2)) so the shooting star appears once every few minutes.
It's a wonderful effect - nobody expects to see this painting suddenly light up. This is the aesthetic we want to explore with ambient computing: incorporate electronics that add a little something, without removing focus from the actual object (in this case the painting).
Ideally, this project should be connected a 3V power adapter, since it's intended to stay on all the time. For now, though, we use the coin-cell battery that comes in the Sparkle kit. In fact, the wall behind the painting has been prepped with conductive paint, so in the coming months, we'll start connecting all our ambient computing projects unto this wall. Stay tuned!
- one mini-canvas
- drafting and painting supplies
- one Sparkle kit (we make this)
Step 1: Layout and attaching components
Keep in mind the frame is pretty thick, so you won't have the entire canvas for Sparkle components.
Next, follow the steps on the Sparkle tutorial to see how you'd connect all the electronic pieces.
