LED Dog Collar

LEDs make everything better, right? What about your dog? [Ken] tries it out on one of his frisky dogs who loves to run whenever she gets out with a LED dog collar. It’s an off the shelf dog collar sporting 5 blue LEDs, and is powered by an attiny2313 micro controller, which makes adding / changing light sequences quick, easy, and also allows for future upgrades. Small PCB’s are made and to help keep minor amounts of the wild from frying. the electronics parts are encased in hot glue, and the whole thing is powered by 3 AAA batteries.

While it’s an early test of the device, and there is more to come, like an automatic trigger as [Sunshine] bolts for the door, but it seems like a great help while chasing after a runaway dog in the dark.

  1. I use something simular from £-land. I have a german shepard and need to use 2 as they are used for children arm’s

    £2 is not bad and bat lasts 4-5 month’s CR32

    Then im left with 12 led’s to play with

  2. In many places you cannot carry blue lights on vehicles since they are reserved for the cops, I wonder if police dogs also have the exclusive right to blue led collars :)

    But ‘link’ is right, you can buy collar attached lights and lighted collars in every pet store for quite a while already, years.
    in fact I’ve seen light to attach to collars in supermarkets even.

    Imagine a dog chasing a car down the road, but now it’s wearing red/blue flashing LED’s.

    I’m pretty sure it will have a better chance of actually catching the car.
