Laser pointers

Hey guys, I can imagine this question being asked a few times, but google did not provide good results. ANyways, I have a CD drive, CD burner, and DVD drive and wanted to build myself one of those nifty laser pointers that can burn matches almost instantly. Which one will have the strongest laser to do this with? I'm assumign either the CD burner or the DVD. so which should I tear into?

DIY Laser pointer

Hello everybody, I'm sorry if this is already explained in an instructable, but I can't seem to find one... My question is, is there a way to make a laser pointer from the laser thingy inside an old cd-writer or an old hard drive (that both still work) ? Thanks

Running a laser pointer? Answered

For a school project, I am running a 4.5 volt, 0.03 amp laser pointer. I need to run it from a 24v power supple. I have tried 1/4 watt resistors, and they ended up smoking. I don't know how to determine what components I need between the + power and the +lead of the laser pointer. Any assistance would be appreciated.

Laser pointer diode

I was making a laser trip wire, but I was looking online for diodes which I found, by which one would be best to get, I dont care for the color, in fact I am better off with red and the intensity can not put off heat to harm anyone. Anyone have any laser diode recommendations or have a site that I can buy them from?

Ipod laser pointer hack...

bought a laser pointer that plugs into a 2nd gen iPod nano (hey it was $2), and since I don't own one, (3rd gen FTW) I took it apart. Now I've got some problems: a) How much power does an Ipod put out? I cant just hook this sucker up to a AA? I don't wish to power it through an iPod. b) The negative wire wasn't soldered, I think i know where it goes but I'd like to be sure All I know is it's a red laser pointer laser, and there wasn't any info on the packaging other than don't shine in your eye...

Laser Tripwire Turned Off By Laser Pointer?

I was playing through my older Splinter Cell games the other day, and had my airsoft pistol next to me. I had attached a laser pointer on it, mostly for kicks and giggles. While playing Splinter Cell, I turned off a security camera by shooting it with some sort of laser from my FiveseveN and it gave me an idea. I decided that I'd like to make a simpler version of this for a scenario airsoft game. So my question for you guys is, is it possible to make a laser tripwire that can be turned off by aiming a laser pointer at some sort of sensor on it? If so, how much would materials cost me, and how difficult would it be to assemble? Could it be pulled off by someone with little electronic experience like myself? Thanks in advance!

Laser conversion from pointer to burn

I could have sworn I saw an instructable on converting a regular laser pointer (low wattage type) into one that would burn (if only a little), i.e. increase it's power output, but now I am finding it impossible to locate. Has it been removed? Are there not proper tags to help me weed out the other half million laser projects? Have I lost my memory and there never was such a project? inquiring minds want to know...

Laser Pointer shooting range ideas?

Idea is to slightly modify the annoy a tron circuit to turn on a laser pointer at a specific time interval, then back off... Then i would put this into my lego mindstorms robotic thingy that will point the laser to random points on the walllink to annoy a tron: https://www.instructables.com/id/Homemade_Annoy_a_thing_Annoy_a_tron/thats all great and a work in progress, really just background inforeal question, just askin, is what technologies are there that would allow a microcontroller to "sense" where the laser is pointing and then to link that info to an sensor that would find where the bb bullet hits? Then just give me a percentage of how far off i was from the dot, maybe in the form of an LED bargraph display like this one: http://www.goldmine-elec-products.com/prodinfo.asp?number=G8942this isnt something i expect to do, but i want to do something with 555s and this looks like a pretty cool ideato clarify, on the top part, the laser and lego mindstorms are 2 separate systems, one is simply mounted on the other, but by using the same timings it is possible to make them work synchronously... its a work in progress, stay tuned if interested

Making a "flexible" fibreoptic laser pointer

Dear knowledgeable peopleI am looking to put together a laser pointer connected to a some sort of a fibreoptic cable to allow a clean projection of the beam at the end of the cable. I have looked at visual detector devices but are they suitable in giving a "clean" and focused beam that can project for at least few metres? The other limitation is that I am looking to work with a class II laser to make it as safe as possible (sneaky kids etc..). If a VFD is not suitable for this purpose how can you connect a simple laser pointer to the cable (?possible ?practical).Finally is the green laser more focused by its nature?Many thanks in advance!!!!

Using a laser pointer to display secret shapes?

Hey, all, I'm working on a puzzle for an escape room right now and am wondering if there's any way that I can use a laser pointer to display a number. My hope is that the number is not on the lens of the pointer, but rather is discovered after the laser pointer is shined through a specific spot on a piece of plexiglass. The players are asked to set up a tripod in a specific spot with a specific angle, mount the laser point to the top of it and then move the point around the room. Ideally, as the point is traveling around the room, it will shine directly on a small part of a plexiglass display and then refract a number on the wall behind it. Any ideas on how or if this is possible? Any and all thoughts are welcome. Thanks!

What happens if you over-power a laser? Answered

If you take a laser (say, a 1mW pen laser pointer) and hook up a stronger battery to it (say a 9V battery as opposed to the 3V watch battery it came with), would it increase the output of the laser? If it would, at the risk of lifespan, would it work if you strobed it?

Model a heliostat with a drill press, laser pointer and mirrors?

Mechanical Heliostats were important scientific instruments over a hundred years ago and one mirror heliostats were often used to focus sunlight on an experiment. Better mirrors became cheap and 2 mirror heliostats replaced them. Then electric light killed off both types.But now, solar energy is becoming important again. Big fairly low efficiency mirrors can be made with mylar stretched across a frame. Perhaps now is the time to get 1 mirror heliostat research going again! (With low efficiency mirrors, 70% efficiency becomes 49% if you use 2 mirrors to reflect the light) So you get less efficiency for twice the expense if you use 2 mirror heliostats!But first we need to model the process. It just takes too long to test your ideas outside! Here is the start of my model of mirrors on an equatorial mount (also called a polar mount) and the sun moving on the celestial sphere. I think that it will end up being very useful. I just gotta find the right mirrors and the right laser pointer. A heliostat with the mirrors moving at one rotation every 2 days, can do this perfect reflection but it is limited to certain angles because the mirror must be upright on the mount.In my model, I have left out the earth's surface for them moment. So we will just model the suns movement, the heliostat mirror movement and have a target to see how much the reflection moves too.Brianhttps://www.instructables.com/id/S1QAZI9FS8O1X6Z/

Dividing a laser beam

I'm working on a project that utilizes a series of laser beams, about 8. Instead of having 8 separate laser pointers/diodes, I think it would be easier if I were to find a way of splitting the beam of light from one into 8 beams of light. Does anyone have any ideas? Something like shining it through angled Plexiglas or some kind of prism?

IR laser detector alarm

With the new Infrared laser pointers etc. there is no way to tell if light is on or not. I think there is a need for a IR laser light detector that is small enough to fit in your pocket and could be clipped to your shirt. If a IR laser was pointed in your direction the sensor would chirp or make a noise. I've noticed several places selling IR laser pointers. I think they are dangerous and very little use for them, since they are invisible. Anybody want to make one? If you do I want one.
