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

I keep seeing DIY plans for "Burning Lasers" are these the same as the red or green Lasers used to point into the night sky at selected stars,planets etc?? Can anyone direct me to info on this type of Laser?  I don't want to burn anything. Just a very strong beam that will point out objects in the night sky.                 Thanks

My macbook pro mouse pointer is freezing up? Answered

I do not use the trackpad. I use an external mouse. Whenever I log in to the computer, the mouse pointer is freezing up. When this happens, I can only use the trackpad to move the mouse. I found a temporary fix: Unplugging the usb and replugging it. It is still quite annoying though. Is there a permanent fix to this?

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: 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: 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

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...

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?

adding a push-button

Howdy! I'd appreciate any advice regarding this potential project.  I would like to take a regular old basic laser pointer and hack it so that I can turn it on and off with a push button, at a short distance, and connected by wire.  The original device may have a rubber button on the side or back, or maybe it's turned on with a twist, or maybe something else. That would have to be left 'on' -- or, better yet, bypassed.  Because I want to be able to activate it by pressing and holding down a button, just like a doorbell. (I suppose flashlights and any number of other devices would work similarly.) For the project I have in mind, having the switch hard-wired to the device would be fine, but naturally I'd love to hear about anyone's wireless ideas! Thanks so much!!!!!

Device to Improve Sound/Lighting/Accuracy for a Digital Camera

Hi Folks, How are all of you? I'm new on this forum and I am glad to be here! :D Anyways, I need some help on a little project I am trying to achieve... I've been working on it for sometime, but unfortunately I am not very knowledgeable when it comes to circuits and need some help. It's kind of complex, so please bare with me. If anything is unclear, please ask me to explain. Okay, here is what I want to do. I want to connect a small microphone, two LED strips, a laser pointer module, a battery pack, and an "on/off" switch all to a handheld device which would allow me to harness my digital camera to it. This would give my pictures/videos better sound, lighting, and a light that will allow me to point at stuff ( the laser pointer). The battery pack would power it separately from the camera, and finally the power switch would all me to (obviously) turn the device on and off. Now, for further detail: -The microphone would be one of those small ones that can be powered off of cameras. It'd be similar to the cheap ones you can buy for your iPod Touch. If you know of a nicer mic that would draw a little more power and thus need to be connected to the battery pack, but be better sound, please inform me. -The LED strips would need to be, at most, 8 inches long, and allow me to provide light from above and below the camera. In other words, I'd basically have two different 8 inch long spaces on the device for the LED strips. It doesn't HAVE to be a strip, but could be two modules of LEDs - say, two 3 inch modules. I say this part about the modules as I'm looking for good lighting, but I want to be able to have it draw the least amount of power possible as I am using batteries to power it and am open to whatever configuration will suit this the best. -The laser pointer module (this will allow me to point at stuff as I am recording it and talking about it), would again need to draw a little power as I would run this off the battery. I would probably use a 5mW red laser module, but I am totally open to any ideas if you know of a different laser that would suit this device better. -The battery pack would need to be as light as possible. I purchased a 4 AA battery holder pack, which seems like it will work, BUT I was wondering if there would be a better way to power this (smaller, lighter, and more powerful, all while using popular type batteries so that way I can still find batteries fairly easy - i.e. 9v, AAA, etc...). Maybe have two separate power packs? Just an idea... -The momentary switches would be for the LED switches and the laser module. I would want one for each so they could be controlled separately. Two last notes: I would like each of these modules (the LED strips, the laser module, the battery packs, and the momentary switches) to be able to be connected to the main device using connectors. This would allow me to keep all the wiring inside the device and not have to re-wire anything IF one of the modules needed replacing (say, the momentary switch for the laser module died), but would allow me to simply detach the defective one, and attach the new one onto the device. Also, I don't know what size of resistors or wiring that would suit this the best. If you could include that, I'd greatly appreciate it. If someone could help me, I'd appreciate it so much. I've been trying to search this forum for this, but can't find a similar layout... I don't really know how to calculate the correct amount of power and all that as, again, I am not very knowledgeable in this... Again, thank you so much. Waldoctg

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!

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!
