Introduction: Easy Red Laser (That Burns) for Under $40

Red lasers are sweet. You can go ahead and buy a laser but those can be expensive and not always be as effective. In this instructable I'll show you how to build your very own red burning laser for under $40. The process and Idea came from this video.http://www.youtube.com/watch?v=_VrNDe9mpOs

Step 1: Parts

Supplies:

1. Laser Diode- can be purchased for $20 on this site.

2. Laser Drive- Can be purchased on this site for $13.

3. 4 AA battery pack. Can be bought at Radio Shack for about $2.

4. Some type of insulation. I ruined my first one by letting it overheat.

Tools:

1. Safety Glasses

2. Soldering Iron

3. Solder

4. 4 AA batteries

Step 2: Soldering

1. First find the positive and the negative ends of the diode and solder them to the front end of the driver.

Step 3: Step 2

Next Soldier the two ends of the battery pack to the other ends of the driver.

Step 4: Step 3

Now turn the screw on the driver all the way to the right. Make sure you don't overturn and break it. This will increase the power output.

Step 5: All Done

That's it. You can add some insulation so that it doesn't overheat. My first one burnt out because I left it on too long with no insulation. Now you can focus the beam and it will light matches, fireworks and make most black paper and rubber melt. Make sure you use appropriate glasses and safety precautions. just by looking at the reflection hurts your eyes and gives you a headache. Remember always be cautious.

    Is there an on off button, how do you turn it on and off

    PLZZZZZ clarify my doubts


    1>want to know that if I use Li-Ion batteries i.e; 18650 which are 3.7v 2600maH,then I have to use 3 of them connected in Series is that right(about 11.1 v )(since the total consumption will be about 7.2v),but these batteries comes with pcb protection so when I will be using this laser will the pcb should posses any problem.Secondly want to know that if this driver can handle 2600mah.

    2>Then in case 14500 which is standard AA(1.5)then have to use 5 of them I guess,plz clarify if I am right or wrong.

    3>Can u plz give the names of the chargers which charges these batteries,1 by 1 charging will not be a problem for me.

    4>plz suggest the best lion battery manufacturers. I went to this site(http://www.candlepowerforums.com/vb/showthread.php?257543-LiIon-18650-battery-comparison)but cant decide which one to purchase.

    Thankx in advance

    deifinitly stole it from kip kay

    Where did you get this diagram?

    You can buy a burning laser, for just under $30. So why buy one?

    1. this one is much more powerful than any laser I could find online. most lasers at this power cost about $200.
    2. It's always fun to DIY.

    nice, when you say insulation, do you mean a heat sink? and if so is it mounted on the driver or the laser diode?

    Any type of insulation. You could probably use electrical tape. I put the diode and driver into an old cheap laser pointer and it ended up heating up and burning the diode out.

    Do the website in the links post to Britain?
