LED dog collar, Christmas edition

[Aaron] says in our comments that he also made an LED dog collar. This Christmas themed dog collar uses an ATTiny13a and a hand full of red and green LEDs (28?). While the animations aren’t as complex as the collar we posted earlier today, we though you might enjoy this one as well. From the description, we think that the LEDs simply fade back and forth between red and green.  We think that [Aaron] did a great job. He has included the source code and schematic on his site, but sadly there’s no video of this collar in action.

    lol, I’ve been using a jogger’s/biker’s flashy clip just clipped to my dog since shes black and I can’t see her at night otherwise… Alas, I’ve also been panning on building an LED-studded collar!

    bought something like that from a pet store few years back, but the thought of putting a µc on a dog is tantalizing.

    Haha, thanks, yes, they fade in and out alternating green and red. Sadly the battery life is pretty short, only a few hours on 2 CR2032s.

    I was just thinking about this the other day…

    I currently use a flash light and was thinking, I should just put LEDs in his collar. Way to read my mind.

    Be careful with pets and those small cells! Those batteries can do horrible things to the insides of pets if swallowed!!!!

    very cool way to keep your snoop safe. you may want to seal that thing up with some heat shrink or something just in case a batt or something falls off n’ your snoop tries to eat it.

    I finally found my old contest entry for the Microchip Start-Now contest from 2005. My idea was to use a micro for each LED, and make the collar scalable for varying size dogs. I never built it, but I did buy all the parts…

    Like it. I’ll have to get a couple. The dogs go camping with us as well.
