How to Make a POV Speed Indicator for Your Dog #WearableWednesday #wearabletech #Arduino #DIY
Have you ever wondered just how fast your dog can run? This project discovered on Hackaday will give you the answer you need; you just have to supply the congratulatory dog treat. Johan Beyers created a POV belt for his Jack Russell-esque dog, Pippi, that illuminates speed markers as they are reached. I’m really in love with this form of data visualization as POV is usually just used for colorful night-time magic.
Johan used a bulkier Arduino, only because at the time he didn’t have a smaller one. However, it did make it easy to mount the protoboard for the LEDs. Note there is no accelerometer in this project, according to the post.
Instead of putting all of the LEDs in a line, they are arranged in a V-shape. Because of this spatial offset, the patterns flashed out only “look right” at the right speed. Each number is flashed at a different speed, so you just look for the least distorted numeral.
One of the humorous challenges of this project was getting Pippin to run with the harness—apparently she wasn’t keen on it. It makes me wonder if a doggie vest with stitched LEDs might be a more comfortable solution. Also, in case you are wondering Pippin clocked in at 20 km/hr. Johan has put together some build notes as well as a nice series of animations to explain how his POV works. If you would like to experiment with some light painting, check out our MiniPOV4 Kit. It’s perfect for those evening moments when you want to send your own messages. You can upload your image into our software and run it through a Processing sketch for some glowy fun.

We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
