Laser Dog Goggles Make Halloween A Nice Night For A Walk

Sure, you could dress your dog up for Halloween in some pre-fab hot dog costume or a little French maid outfit, but what’s the fun in that? Hilarious as it may be, there’s no hack there. [Becky Stern] will help you out of your pet costume rut with the tutorial for her latest creation, laser dog goggles.

First things first: the laser she uses is fairly benign. You can safely stare it down for just under 30 seconds, so your pet should be okay. [Becky] offers other helpful safety suggestions, like covering the delicate battery pack with fabric to avoid scratching damage, and waiting until the adhesives are completely dry before outfitting Rover. But hey, if your dog isn’t into eye wear, don’t force it.

These are based on Doggles brand dog goggles and the Adafruit Trinket. The laser is mounted on a micro servo so that it pivots back and forth, allowing your dog to scan the ground like RoboCop or Terminator. As you might expect, [Becky]’s tutorial includes a comprehensive list of tools and great documentation. Check out her video overview after the break.

        How much is that, Can you tell me as I add them on my cart?
        Tonight we are so much DIYing.

  1. I could be mistaken, but anyone incline to duplicate this they should be able to so so without buying a damned thing from Adafruit. Perhaps if they can’t they probably are not a hacker?

  2. Dog eyes are wayyyyyy more sensitive to light than our eyes, so how do we know this is safe for the dog’s eyes? I guess we should ask the dog right? Oh yeah…. dogs can’t tell us if this is hurting them for sure… But as long as the humans are amused, right? and how long does it take for damage to occur with reflected laser light, and again, dogs eyes are built for low light, so they’ll be letting in even more laser reflection. It’s bad enough when people treat their kids like pets, but please don’t be a stupid pet parent and treat your pet like you would your kid….

    Yes, I was that guy that went there. But maybe someone should go there every now and then….

    1. “Interestingly, some authors have reported the incidental finding in laser workers of peripheral retinal lesions consistent with old laser injuries, although no recollection of such injuries could be evoked (Fig. 5). Presumably, threshold laser injuries to the peripheral retina had been asymptomatic and had gone unrecognized. Accordingly, the number of accidents reported in the medical literature might not reflect their true incidence.”

      Barkana, Y., Belkin, M. (2000). Laser Eye Injuries. SURVEY OF OPHTHALMOLOGY, 44(6), 459-478. DOI:

      Perhaps it is indeed unreasonable to rely on a pet’s self preservation or blink reflex if injuries can go unnoticed in humans.

      1. Idunno. On the surface it looks like another ‘publish or die’ junk report.

        Some injuries on some people who work with lasers could have been from lasers though there is no proof or even recollection of an incident and thus official measures of incidents could be wrong. That sort of thinking can be applied to anything.

  3. Hey Becky, great dog you got there, looks a lot like mine. AmStaffs a the best, specially if they are ‘interested ‘ in electronics ….;-)
    Take care !
