No Soldering!!Cheap Burning Altoid Laser!!!





Introduction: No Soldering!!Cheap Burning Altoid Laser!!!

This is a burning blue laser made in an altoids tin.
The parts were $43 total and this laser, is BEAST!!

1. Altoids tin- $3
2. Laser module-$38

4. Battery pack-0.91

This is the instructional video: this was made by styropyro and I credit him

Step 1: Tools

You will need...
Soldering iron(optional)
Drill/ dremel
Electrical tape

Step 2: How to Put It Together

Tie 1 red wire to one side of the switch and the other to the other side. Solder if possible.
Tie the 2 black wires together and cover with electrical tape if you can't solder. Then, drill a hole in the altoid tin for the module. Then drill another for the switch.

Step 3: Done!!

Now that you're done, you press the switch and the laser will come out!(Be sure the battery pack switch is turned to on) always be sure to wear safety goggles!!!

If you want to see the more descriptive instructions, watch the video,

Thanks in advance!!

    Perfect thing to show off to my friends... I will just have to make sure that they wear safety goggles, no questions asked. I hope my mom doesn't get mad at me if I accidentally burn the wall.

    50 mw but wear laser safety googles

    Sweet, Thank you

    You could always get a green module for like $5-25 and just turn the potentiometer for extra power. If you want a link, just ask

    While this would probably work, you run the significant risk of burning out the diode, and a guaranteed chance of shortening the overall life span of the diode.

    While it is great of you share the thing you've made, I do have some strong concerns with this instructable.

    1) The output of the diode you've used and recommended is beyond the range of what is generally considered safe to use with no eye protection, and is sufficiently powerful to cause permanent damage, if not blindness. This is made worse by the fact that it is within the blue light range, which has has been shown to be more harmful to eyes than other wavelengths.
    Yet nowhere at all is eye safety or protection mentioned. This concerns me deeply, as even a near miss can cause damage. I would highly recommend adding a preface of text at the beginning of this instructable, letting people know that they should always use appropriate eye protection for the laser wavelength they are using.

    2) You've linked to a video that isn't yours, but you haven't given credit to the original author. Normally I wouldn't get worked up over this, but because you've entered this instructable in to a contest where you stand to gain something if you win, you've committed a significant faux pas.

    Continuing this train of thought, your instructable is pretty much just a rehash of that video, but with the important safety part left out.
    Submit something original for to contests, and give credit to the original author of the video.

    it says wear safety goggles smart one and it says styropyro im reporting you

    you don't have to get the same laser diode as he did you could always get a smaller on, for example I made one of these before I saw this and I used a very small one that was 99¢ and it was still decently bright

    I would do this, but it's really expensive for a DIY laser product. Why not salvage some lasers instead?

    Salvaging something instead of buying a new one is always a great idea, but not always applicable.
    I've salvaged a number of laser diodes from CD/DVD readers. The problem is that they are:

    a) Usually under powered. Generally speaking CD/DVD lasers are only a few mW, and nowhere near enough to burn things. Only a few CD/DVD burner lasers are powerful enough, but those are usually IR lasers and hence not visible (also very dangerous).

    b) Don't come with a driver or a lense. Drivers are necessary to if you want any kind of usable lifespan from a laser, especially a burning one. While laser drivers aren't too hard to build, but if you don't know the specifications on the diode you've salvaged you run a significant risk of burning out the diode (I've done it a few times). And a burnt out diode is of no use. Lenses are needed to focus the light; without them you have a curious but dim flashlight.

    In this case it would just be easier to purchase a new diode and driver module. You might pay more, but you would at least know what you are getting.

    someone should make a sonic screwdriver do this... ...that would be cool

    So like .1w+ will burn

    .1 w can already burn

    Do you have any color specification?

    You could get many varieties of laser that can burn

    cool what other lasers could i get to burn better?
