There are several different ways to make a hand held laser pointer. In this case we will be creating one out of a flashlight body.

Now these lasers can be very dangerous. I built one that is only 5mw and can not burn, but for about $5-$10 more you can easily find a module that can burn (I will include links to these).

Note: At about 100mw it is possible to light things on fire.

Step 1: The Parts

You will need a flashlight body, you can take a old broken flashlight. Minimags work well.

Step 2:

Next step will be to attach the positive end of the battery to the red wire (positive) like so

(ignore the circular metal object around the diode thats just part if my flashlight body)

Step 3:

Attach black wire (negitive) to the bronze tab inside of the flashlight body (your flashlight body might be a little bit different but this is what most flashlights look like.

Step 4:

Insert the taped battery (and any other batteries necessary). Put diode into the cap on the front of the flashlight (you make need to make adjustments on the front itself)

Step 5:

Screw the cap on and you're done! Hopefully yours work'd as well as mine did.
How to make a burning laser???
<p>yep, that ed be cool.............</p>
(If you want it to burn paper)
Hey is there a way to make one without a laser modual
What do you have in mind?
I have a 10 mw red laser and im not sure what batterys to use. I might just use a torch to hold it all. (I dont care if it burns or not)
<p>how do you attach the wires??</p>
Well I used some electrical tape but that doesn't always stay put so you could just solder it on, which would be very easy to do
or well suppose to mean
<p>it stands for milliwatts </p>
hey quick question whats the &quot;mw&quot; stand for
Cool idea!
