POV or Persistence of Vision where you use flashing LED lights to display letters in motion, has always been a fun way to learn about LEDs and circuits. You might remember I invented the world’s first Golf club POV, which was capable of showing letters/images while you swing the golf club.
Well, there’s a DIY Doggy Style (literally doggy dog) POV someone has managed to put together with his furry little helper helping him in pitch darkness.
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 (Ianto) is 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.
