50mW Cat Toy

[Minousoft]

Just wondering if 50mW of green hitting a dark gray surface could be dangerous to my cats.

Anything >5mw can be dangerous. Get a 5mw red for $2 from dealextreme if you want to play with your cats.

That's what I use, those cheap pointers. don't want to hurt them

what about OD3 goggles for my cats. lol.

my cat won't chase any laser over 5mw... it seems if he sees the beam he isn't fooled

I have found my cat likes a uncolimated beam with a spot about 3-6 inches wide.

Cats vision is not that good, but to make up for poor vision their eyes are hyper sensitive to any movement. Cats are more sensitive to the upper region of the color spectrum, so a 10mW 3-6 inch spot humans can bairly see, cats see it just fine.

I'd be curious if a 780nm IR dot is visiable to a cats.......

My cat likes a collimated dot. I always heard cats couldn't see red, but one of my cats loves red lasers. The other one can only see the laser when it is farther away, and doesn't chase it.

It would be cool if cats could see NIR.

They see slightly into the UV range as well (which helps explain such great night vision), making a low power blu-ray pointer very fun for them. You can hardly see the thing but they are on it like white on rice.

Let me guess, running XP or Vista? :

 

[f22warzone]

xp works ..... most of the time..... vista just dosent work ..... any of the time

 

[VillageIdiot]

Hey, I have Vista and it always works for me every time, it just eats your RAM, nom nom nom

 

[brtaman]

Yep, also on vista...couple of months, no compatibility issues...no BSOD's :O

Disable the crap transparancy etc. memory footprint ~= xp footprint...nice stable os...


So did you find any new ways to have fun with your laser?

@brtaman
I got this prism-like plastic material from a craft junk store. It seems to be the same material you can use to make those cheap so-called 'holograms.' (the ones with 2 possible images) It splits the visible beam into two visible beams 45 degrees apart. (a Y shape) The two visible beams are the same brightness as the original beam
It makes for some cool effects.
