This is what it looks like when a dog writes a book in the park with LEDs

Michael Zoellner:

Mounting 5 LEDs on a moving object creates one of the cheapest and largest displays: Persistence of Vision. It’s been done on bicycle wheels, fans and other rotating objects.

In this project i am sewing a Lilypad wearable Arduino board and five LEDs with conductive thread on my dog’s shirt. She’s a Miniature Pinscher running very fast for fun. In curves fast enough for Persitence of Vision. And she likes running in large circles in the park! Light writing.

The dog is writing Cory Doctorow's excellent novel Makers.
