***UPDATE PLEASE READ*** If you are going to build a laser the curcuit used in this video is a BARE MINIMUM. Although the one I made in this video still works fine to this day, you will probably want to add a small capacitor (anything over 10v 16uf is fine)in parallel with the diode to even out any voltage spinkes from the battery. To build a well regulated circuit check out www.laserpointerforums.com for some great, easy to build, current and voltage regulated circuits for lasers. You can buy pre-made drivers for lasers off of:
sales.lasingpix.com
One thing to note is the prices of the diodes have jumped from $13 to $19.50 but you can buy the diodes off of sales.stonetek.org


In this video I show you how to build a homemade high powered burning laser.

Parts:
You can get 100ohm potentiometers off ebay for pretty cheap
You can get you switch and battery holders at any radioshack
You can get your laser diodes at laserpointerforums.com for less than half of the price of pulling them from a DVD burner (and a heck of a lot easier)
You can get AixiZ modules from Ebay Seller aixiz_lasers

A few tips
-DO NOT LET ANYTHING SHORT!
-When you have turned the pot so the brightness turns high, don't even think about turning it more to make it more powerful. If you do that the power will go from 100mW+ to .1mW and your diode will be screwed
-buy more than one diode cause they can break by simply touching them sometimes, too much current to the diode or a ton of other things so you will be safe bbuying more, and if you have extras build more modules and sell them to your friends for even more fun! (go ahead and charge $100 for them so you can be rich)
-Buy goggles for these things! Goggles cost around $40 and are easily worth it, your eyes are worth more than $40 and if you get hit in the eye by this thing without goggles on, you're screwed.

  • Nice video, Styro !

    I remember this when you published it, before this a$$wipe stole it !

  • cool

    very good tutorial i want to do this but i cant get a diode from the forums because im from the uk

    By peezo 1206275678
  • why make it?

    when i get get those for 20php- 50 cents USD
    made in china

  • Stolen!!

    That video is mine! You were too much of a dumba*ss to remove the styropyro part of it, I am styropyro! I own the copyright to that video and if you do not remove this video I will be forced to take legal action against you. I hope you will enjoy jail, thief.

  • This is just daft really.

    You should at least give a disclaimer on your video...
    Also carry on handling high power diodes like you are and you are going to end up, at the vary least seriously damaging your eyesight, probably losing it.
    Can we all watch that video when that happens?

      Wish i was able to make that :) 5 Stars Hun!

  • burning laser pointers....

    woah, that's pretty cool. seems kind of like the < $200 burning laser pointers they have at NitroxLasers.com

    these can light matches, pop balloons, and light fireworks, but have a higher power output than the laser pictured here...

    • weak

      dont be a tool

    • The real lasers are at

      WickedLasers.com They actually get military contracts and developed a laser to go on guns and disorient attackers so they can take them down easier.

      By rhgwynn 1201990615
    • I have seen the name of the company

      that got the contract and it is not Wicked Lasers, the company that got it is getting 10,000$USD though

  • Thats pretty neat!

  • stolen!

    he stole this from kipkay!

  • Not so fast please.

    The top side of the balloon it's outside of the camera field of view.
    Occam's razor?

    By Stendall 1203028225
    • he's right

      Even really good lasers take longer than he did to pop balloons.

      By Fluffyjimmy 1203464004
  • the higher powered

    are more resistant to damage and can be driven much harder, I get them from brand new DVDRW drives.. Check out my video of one doing a lightshow by bouncing off a cigarette lighter.

    Will the laser in this tutorial do that?

  • i thoght,,,,

    dont dvd players use infered not red......

    By lonewolfzor 1200956151
    • No,

      DVD players use visible 635nm, which is a good wavelength cd players use infra-red 780nm, although it is still visible.

      By olly_k 1203791858
    • they use both

      IR and Visible Red.. two seperate diodes
