Step 4: Burn stuff!

Put in 4 AA batterys in the battery pack, and fire it up! The laser dot is really bright. I like to shine it through my neighbors bathroom window and scare the crap out of him(not a good idea). But anyway have fun, be safe, and don't get caught.

Oh yeah this is my entry for the wicked lasers contest, so if you like this instructable, please vote for me.

<p>Hi can you please help me? i have a question, I have bought this laser with driver on ebay &quot;100mW 650nm Red Laser Diode Module with Driver(Power AC7V or DC 7-10V)&quot; this is the info/description but I just think it is fake and this is not a really 100mw/650nm laser</p><blockquote><strong>Laser Color Red</strong></blockquote><blockquote><strong>Laser Power 100mW(&plusmn;10mW)</strong></blockquote><blockquote><strong>Warm-up <br>time (minutes) <8min</strong></blockquote><blockquote><strong>Power <br>Stability 5%</strong></blockquote><blockquote><strong>Operating <br>temperature (℃) 10~40℃</strong></blockquote><blockquote><strong>Size of <br>laser module (mm) &Phi;18*40</strong></blockquote><blockquote><strong>Modulation <br>TTL Leve 0~30K</strong></blockquote><blockquote><strong>Output <br>Beamdiameter(mm) 2</strong></blockquote><blockquote><strong>Power AC7V <br>OR DC7-10V</strong></blockquote><p><strong>Output Wavelength(nm) 650nm<br><br></strong></p><a href="http://www.ebay.com/itm/100mW-650nm-Red-Laser-Diode-Module-with-Driver-Power-AC7V-or-DC-7-10V-/252052633693?hash=item3aaf81f85d" rel="nofollow">http://www.ebay.com/itm/100mW-650nm-Red-Laser-Diode-Module-with-Driver-Power-AC7V-or-DC-7-10V-/252052633693?hash=item3aaf81f85d <br></a><p>This laser dont pop balloons or burn thngs, can I just replace the laser diode with the laser diode from the dvd/rw and it will work for burn things?

<p>I was thinking that with that PWM-OCM i could regulate the power and chose whether it burns or not.</p>
<p>Could I use a PWM I have from RMCybernetics (I used it for motor control with a Van De Graaff generator) </p><p> <br></p><p><a href="http://www.rmcybernetics.com/shop/PWM-OCm" rel="nofollow">http://www.rmcybernetics.com/shop/PWM-OCm</a></p><p>One of these</p>
<p>I'm a kid oh 12 years old, can i make it, i'm from india where can i find the parts </p>
<p>can you do a video for this? <br>It'd be really helpful! :')<br><br>cheers! </p>
<p>Hello guys.</p><p>It is important to get the right old dvd, it has to be a Class 3b laser inside and not all dvd especially the new ones have lasers in lower classes. Look on the backside of the dvd drive a yellow badge shows what class laser it has. It has at least to be Class 3b, Class 1 is even not dangerous to the eyes. try this link: <a href="https://en.wikipedia.org/wiki/Laser_safety" rel="nofollow">https://en.wikipedia.org/wiki/Laser_safety</a></p><p>And a heatsink is also necessary or the laser will burn out in no time. </p><p>Sorry for bad gramma and spelling.</p><p>Have a nice and laserbright day</p>
<p>How can I add a heatsink?</p>
To make a heatsink get an old heat sink from old grafikdrive or old amplifier drill a hole with dimension so the laserhead just fit in apply a little drop of heatpasta to the laserhead before puting it in the drilled hole, thats all.<br>The right laser is all about what class it is on the back of all drives is written what class it contains it has to be class 3b at least.
<p>would it be safer to use if i had on smoked glass goggles or sun glasses? </p>
<p>also can your laser melt solder?</p>
<p>I opened up a few old electronics and now I've got one infrared, two red, and one blue laser. Will this instructable work with the blue or infrared lasers? I know I can't see the infrared, but could it still burn?</p>
Just to let you know, that popping sound your eye made was the water in your eye heating past 212 degrees farenheit, leading explosive boiling of water inside your eye. You're hella lucky you're not blind in that eye. Play safe, and have fun burning shit fellow pyromaniacs ;)
<p>Could you use a 9-volt battery instead or is that too strong?</p>
<p>how do you get such a huge cylinder from a cdrom laser head ???</p>
<p>i made my laser according to the instructions but it won't burn anything and it is dim.</p><p>Could the dvd drive have been preused and is already kind of burnt.</p>
<p>Are you sure it's a DVD writer and not a DVD reader or a CD drive? Those are less powerful...</p>
<p>radioshack? why do you suppose all people live in USA?</p>
<p>well, most people know what radioshack is i would think. so you could most likly find a similar store close to you.</p>
<p>Saw quite a couple of these instructional videos and everyone's saying to extract the diode and build a driver for it on another heatsink/casing.</p><p>But I just wonder why not just leave the diode as it is in the laser carriage assembly and simply power it up with whatever ribbon cables it is attached to? </p><p>Saves all the trouble don't it?</p>
<p>Okay everyone, I'm finally back on Instructables :)</p><p>Looking back at this instructable...reminds me of my early days :P</p>
do you know if a laser from a lg gsa-5169 dvd/cd burner would work for this project? I'm fairly new to this kind of laser fun, but I'm loving figuring it out.
is this laser ok to use its from a Sony cd tape player
I hooked mine to two AA batteries, after a while, the laser dimmed, I couldn't make it go bright again even after changing the batteries, did I just &quot;partially&quot; fried the laser diode?
<p>Is it safe to hook the laser directly to a small CR2032 battery, or is that enough to fry it? (The Chinese do it all the time.)</p>
<p>is there any substitute for the 10 ohm resistor, because i can find much that arent expensive. (I live in europe not america btw) thanks</p>
<p>This is the first time I&rsquo;m trying anything laser diode <br>related so I could just be totally wrong, but it seems like not every DVD burner <br>has the type of laser diode with the metal cap on it needed for this project.</p><p>I bought a &ldquo;DH-16A1L SATA LIGHTSCRIBE DVD&plusmn;RW DRIVE HP P/N <br>5188-7537&rdquo; from EBay and took it apart to find both laser diodes had no caps on <br>them (the crystal was exposed).</p><p>And I bought &ldquo;Toshiba Satellite C655D Series CD-RW DVD&plusmn;RW <br>Multi Burner Drive TS-L633&rdquo; from EBay to find a diode that did not have much of <br>a body at all. It had the flat round <br>back with the pins like normal, but after removing the heat sink material that <br>should have been encasing the front of the diode I realized that the heat sink <br>was the body of the diode with the crystal resting in it.</p><p>Can someone who has completed this project successfully please <br>suggest to me a make and model DVD burner that works for this project.Thank you.</p>
<p>Well, the diodes that you got from the DVD burner(s) should work just fine for this project :)</p><p>The diodes with no caps are known as &quot;open-can diodes&quot;.</p><p>They should work just fine, they are made without caps because the manufacturers want to save money. It should still fit into an Aixiz module, but just be very careful not to touch the exposed crystal.</p><p>For more information, check out this link: </p><p><a href="http://laserpointerforums.com/f44/laser-diode-vs-open-laser-46381.html" rel="nofollow">http://laserpointerforums.com/f44/laser-diode-vs-open-laser-46381.html</a></p>
<p>would it work if i connect the battery pack directly to the laser diode?</p>
<p>You COULD, not very healthy for diode though.</p>
<p>Will a LM317T work for this project.</p>
<p>Do you need the Aixiz module or can you get by without it? If not, why?</p>
it's a heat sink, and audio houses the collimating lens that focuses the bean into a dot
<p>I opened up a radio/CD player, and found the 3 pin diode and tested it with 2 AA batteries. But when I attached the wires, there was no visible light coming from the diode. Is it possible this thing is in an another spectrum like Infrared ?</p><p>Please help ! </p>
yes, cd uses infrared. only dvd players and burners use visible red light. blue ray player uses blue to uv I believe
<p>i too tried connecting the laser directly to a 3v battery .... and its heated up fr some secs and then stopped working .i saw ur ansewr to the problem. my question is that can i use a capacitor to regulate the voltage?and not only a capacitor is it ok to use an old capacitor which was used in circuits??and will the laser spoil if i do not use a resistor??</p>
<p>mine just showed a really weak red dot.</p>
<p>I can just improvise with my module.. its all in the focusing of the lens right?</p>
<p>nice I like it good job</p>
<p>What is the use of Aixiz Module? And can I make it without Aixiz Module?</p>
<p>You could make it without the module, but then it would be more like a flashlight then a burning laser. The module helps focus the laser into a beam, which is why it can burn things.</p>
Hi I remove the laser sled and I see one diode. On your picture the diode is encased. Do I need to remove everything around the diode? Where is the positive and negative on the diode? Thank you for your help.
<p>Yes, you want to remove everything around the diode; the diode should look like this: <a href="http://www.futurlec.com/Pictures/LASER_RED.jpg" rel="nofollow">http://www.futurlec.com/Pictures/LASER_RED.jpg</a> (pins won't be that long tho). For me, there was a piece of metal in which my diode was encased in, I had to carefully break it off or else the diode wouldn't fit inside the module.</p><p>Oh and about the positive and negative connections on the diode...it is shown in the first picture.</p>
<p><strong>Hello i took parts from a old radio cd player</strong></p><p><strong>10 ohm resistance ( i have been lucky only 1 in it lol ) </strong></p><p><strong>and transistor ( not lm317 ) but 2SD882</strong></p><p><strong>A laser diode from a ps3 bluray </strong><strong>kem-450 DAA , 3 pins .<br></strong></p><p><strong>All seem to work with a 6V battery but i need at least to buy the module .to focus the light .</strong></p><p><strong>Because for the moment it look like a flashlight not a laser .... ( blue light )</strong></p><p><strong>brightness is very low, I have made a mistake? or should i buy a module then try again ?</strong></p><p><br></p><p><strong>Thanks :</strong></p><p><br></p><p><strong>Dhal from France<br></strong></p><p><br></p>
<p>The brightness is low probably because your diode is not getting enough voltage/current. Since you are using a different diode than I am (Bluray), the needs of your diode are probably different from mine. Also, the fact that you are using a transistor may be the problem...I'm using a voltage regulator lol. The module is only used to focus the light, if you have very low brightness then it must be something wrong with the circuit itself.</p>
I hope you know that you don't solder on the breadboard
<p>Yea, I didn't want to solder cuz I was being lazy...lol</p>
<p>im making this for a school project. do you have any tips or tricks on how i could make it stronger, diffrent colored, etc...?</p>
<p>If you want to make it stronger, you could decrease the resistor values by a little (don't overdo it) and the laser should be brighter. If you want to change the color, you would have to get a different diode because every diode comes with a set color that cannot be changed.</p>
