    Safety question about 5mW red laser (eyes itching)

    Lol, that is funny. My model is just a cheap ebay laser so the switch is the average kind that turns the laser off if your finger is not pressing it. The pocket clip design is terrible though, the laser emitting end points at your face if you clip it to your pocket. Sooo not safe! My cat is...

    Ever point a laser at the sun??

    I thought it was 8... No; I'm quite sure it's 8.... wait.... Yes, the internet confirms that it takes 8.333 min for light to travel the 93,000,000 miles from the sun to the earth.:can: [Update] Never mind. It takes 16 min for you to SEE the sun's reaction. *Face palm*

    BEWARE of ARCTIC BATTERY EXPLOSION

    Ouch! that's horrible. Lithium batteries do make pretty nasty explosions when they rupture, thats why they are also equipped with more safety features than any other battery. If the battery was really 3 years old it might not have had a built in charge control chip to monitor safety thresholds.

    Safety question about 5mW red laser (eyes itching)

    Thanks to all of you for your time. I've also found a small trick/solution to playing with cats and lasers. If you shine the laser through your t-shirt a beam is still produced, but it only has 1/4 the intensity of the normal beam. holding the laser a cm from the fabric or applying two layers of...

    Safety question about 5mW red laser (eyes itching)

    I'm not sure, it looks like a small diode inside a small aluminum reflecting chamber. It's a bit dark and the hole is small so I might just not be seeing the lense. I any case I can't find a way to remove the cap, the manufacturer must have glued it on or something. :shhh:

    Safety question about 5mW red laser (eyes itching)

    That's probably it actually. Thanks. When I was playing with my cat I was trying to keep my eyes open as much as possible to avoid accidentally hitting my cat in the face with the laser dot. On a side note, does anyone know if it is possible to fit a cheap laser pointer like this with some kind...

    Safety question about 5mW red laser (eyes itching)

    Well since people keep suggesting it might be over spec then I shall have to stop letting my cat play with it. :( Here are some quick photos I took. The first one is on a white wall, second ones are on a light blue wall with the laser dot projected next to a 60w eqv CFL inside a fixture, last...

    Safety question about 5mW red laser (eyes itching)

    Thanks, am definetely trying to aviod direct exposure, for me, my family, and my cat. (although I'm starting to think I should get a separate <1mW laser for kitty though). 5mW or 100; the damn thing doesn't even have a focusing lense! at 40m the dot is over 2ft in diameter! XD BTW probably...

    Safety question about 5mW red laser (eyes itching)

    Thanks. I don't think it is way overspec; if it is though as I said, if I point it at a patch of sun they seem to have similar brightness (the dot doesn't stand out from the surrounding light by a large amount). Would uploading a photo help?

    Safety question about 5mW red laser (eyes itching)

    Hello, I am new to the forum and have an important safety question. I have read many laser safety manuals and guides online prior to ordering my laser, so I know the basics and some of the advanced, please no pointing out obvious things like "don't shine the laser directly into your eye". Also...
