Homemade Laser Flashlight

  • I don't know

    which metal gear flashlight I am supposed to get, can you tell me if it is the L.E.D. one that target currently sells. and if it is, is it the small one, 45 lumens, or the big one, about 120 lumens. Any help would be greatly appreciated.

    where can i find a diode, how it looks like?

  • tell

    me some more about this....

    were can i find a flashlight like that to modify and can i just take a laser diode out of an old computer?

    also what is a driver circuit and where might one find one

    • Well

      I would recommend a dorcey metal gear flashlight like I have. There's plenty of room and it's very easy to get the bulb out. The diode has to be from a dvd burner, a 16X Dual Layer or better. If it isn't 16X or higher it won't be powerful enough to burn stuff and ignite matches. If you look below I posted where you can get most of the parts.

    • The Diode

      the diode in a DVD burner wont work, they have there own driver circuits, and if it was powerfull to light a match at 2-3 feet it would melt the dvd, i think the diode is a one out of a laser pointer, 50mw or higher [i have a green 50mw laser pointer that runs on 3 AAA's [from ebay]]

    • No.

      The drive does have a driver circuit for the laser diode but it doesn't melt the dvd. It uses various voltages and currents in order to write data on two different levels of the dvd. The bottom of the dvd is also covered in a reflective material, not black. If the bottom was black, then it may burn the dvd since the color black absorbs all the light the laser is putting out.

  • Kipkay's

    is better...

    By im2short2die 1192485529 Reply Spam [+1] Moderate Up Moderate Down
    • Actually

      It isn't. His maglite does not have a regulating circuit in it. Therefore, his laser diode that he spent $50 bucks on, is gunna burn out a lot quicker. My diode that I used for Kipkay's design blew out within a few days. So that was $60 bucks down the hole, since that how much the drive cost me.

    • great idea

      good day dandeman321

      i like your stuff its cool
      may i know the diode that you used so that i can make some too. thanks

  • just a few quick questions

    i have this flashlight and i measured around 600-750mA going to the LED and before i install one of my few precious 16x diodes i want to make sure it isn't going to fry. Because i was under the impression the recommended mA for these 16X diodes is 250mA with (around) 3 volts. Am i correct with these figures? because i want a long lasting burning laser not a 15 minute burning diode execution! thanks for the help mate! (of course i don't plan on running it continuously for 15mn! I'm assuming it has a 30-60 second duty cycle?)

    thanks!

  • help pls

    what can i use instead of a aixiz housing?
    how can i built a regulating circuit?

    By myrhinegold 1199456306 Reply Spam Moderate Up Moderate Down
    • Nothing.

      There is nothing that I know of to replace that at the moment, sorry. As for the regulating circuit, There is a link that tells you everything you need to know but I can't post it. I'll send it to you in a msg.

  • PLEASE Help !!1

    So i took your advice and picked up the dorcy metal gear, installed the 16x diode and it works...very bright but doesnt burn anything why is that ???? how does it work but not burn ??????

  • what one do u have

    i have the same flashlight but the top doesn't screw off help me plz

    By xXxMinionxXx 1198107321 Reply Spam Moderate Up Moderate Down
    • What one do you have REPLY !!1

      lol you have the right one...i bought one off ebay and the top wouldnt come off either you have to take two pairs of channel locks on the top and body of the flashlight to get it off...

      By emandreg017 1198112709 Reply Spam Moderate Up Moderate Down
    • where

      where are they and what do they look like? thx for the reply

      By xXxMinionxXx 1198121817 Reply Spam Moderate Up Moderate Down
    • im not sure what your asking but..

      channel locks are like pliers you can use those or two huge cresent wrenches. either way you have to take one and grip it on the cap and take another pair and grip them on the middle of the flashlight.. then lefty loosey righty tighty lol... it might take a little muscle but it will come off and it wont break .

  • 2 questions

    did you use an aixiz laser housing like for the mini-maglite mod? if not what'd you use?
    and second, the big one:
    would this work for a blu-ray diode?

    By redhead3031 1195075062 Reply Spam Moderate Up Moderate Down
    • Yes

      Yes I did use a aixiz housing. I am not completely certain if a blu-ray diode would work. This site
      laserpointerforums .com
      will be able to answer that for you though. Remove the space in between the .com and the laserpointforums

    • cool

      thanks, awesome mod by the way, as soon as i get some time i'm going to try it, and depending on what everyone at laser pointer forums says, i might try it with a blu ray diode
