laser?

I heard a laser could shut down cameras. How do I know if one is used on my cameras to protect my house.

Laser

After reading this, and then this, I started thinking of how easy it would be to make a burning laser. I went to Radioshack, got some components, and started thinking. One thing that Stephanie's laser didn't have is a potentiometer, to control the power of the laser. Well, I ended up getting 12 assorted pots at Radioshack, but didn't know what one to use. I want decent control, too. What size (in ohms or k-ohms) do you think I need? I'm spotty in my electronics knowledge. PS- The size in ohms on the pot is the pot's range, right? If it says 100k, it means that it will resist from 0 to 100 kilo ohms, right?Also, in the shematic below, I don't know if the pot is connected correctly, post a comment if it's wrong.

He’s just ironed out the bugs and you can see him play it here. Whatsmore, he has detailed the entire construction process on the Internet. He reckons anyone can build one for under US$600 after purchasing his US$19 Laser Harp Plans and Source Code.

Surgical Laser

Hi all!So, I have been volunteering at an animal hospital in my home town, and I have been allowed to observe 11 surgeries so far, 4 of which have been performed with this 30 Watt CO2 Surgical Laser. I would like it if someone could explain to me how a CO2 laser works, and I would be willing to answer any questions. the surgeries I have watched are: (1) a spay on a dalmatian (2) an entropion correction on a bullmastiff (3)a cauterization of a bleeding tail tip (without anesthetic & with me holding the dog down!) and (4)a front declawing of a cat.

Laser soldering

So im making a  laser spirograph (https://www.instructables.com/id/Laser-Spirograph/#step1) and i just got my laser diode to come out of its case, and i was wondering where i should solder the red and black wire as it does not look like the one in the 'ible. the laser diode looks like this one here http://10mW 532nm Green Laser Module (3V 11.9mm)  (i would take a pic of the diode but i cant find my camera!) the only difference in the diodes is that mine has a black button instead of the red. Oh and one more thing is that it has to bypass the use of the button. Thanks in advance!!!!!!!!

Lasers on motors

I am trying to create 8 motorised lasers that move (ideally randomly) between a 135˚ angle. I doubt with my level of knowledge i will be able to make them move randomly but if i can't just moving back and forth between the 135˚ would have to do.These motors would have to be reversable and travel between 2 points making an arc of 135˚, I'm looking at making this in the cheapest way possible. By mounting cheap pen lasers onto mini motors and somehow getting them do this. I will need to see the beams of light so unless i can find a better way to used focused light cheaply, i'll have to use a smoke machine or something. Having no real knowledge of this, would it be easily achievable, i would use a microcontroller to make the motor movement random within that 135 degrees but i have no idea how i'd go about it.
