    In this episode of HACKED! I will show you how I extracted a laser diode from a DVD Burner which should have the power to ignite a match. In order to power the diode correctly I will also demonstrate how I build a constant current source which delivers a precise and steady current to the load.

      Actually gives me cause for puzzlement but otherwise HIGHLY delighted that they do. I could spend a week at our recycling plant saving a fortune in bits, pieces and perfectly usable components Just today picked up two fully functional Makita drills, both two speed and one a hammer drill also. Well used but otherwise look in pretty good condition, only missing batteries - big deal - get on eBay for less than £25 for TWO!. Don't need the standard chargers as they f**k up batteries big-time. Have my own which doesn't! Also collected three PC's c/w psus and some older DDR400 memory (I needed some for an old shoe-box PC too), a few DVD RW drives (hence being here) LOADS of SMD components I can recover off these if the boards don't work. Amazing stuff people chuck away. A few fans (I always refurbish fans whenever I can. A few drops of 3-in-1 oil onto the bearing from behind the stopper - or sticker - work it in and bingo. I have one fan that I've re-lubed twice and it's still going after 16 years!! Quiet too.

  • @Jimbo78ify
    @Jimbo78ify 8 ปีที่แล้ว +3

    They make precision voltage references for small amounts of current. Basically you can use it similar to the schematic with a few changes. Constant voltage across a resistor = constant current. The precision voltage references are used in IC's like LM34 and LM315. The LM1117 is a low voltage high efficiency voltage supply that would be ideal to run this kind of application in addition with the voltage reference and a battery pack. Nice application and tutorial.

    I would think you could use a high current pulse to drive the laser much harder. You can do this with infra red LEDs when you need to send the light over a longer distance. The data sheets will tell you how much current and for how long of a pulse to use.

    The Technics SL-P1200 CD player had a particular point of failure in the CD door switch. The switch was a blade that contacted copper fingers, meant to prevent the player from operating whenever the door was open, because potentially a user could look right at the laser. But it was a crude design, so we had to replace them regularly.

    If the forward voltage of the diode is less than 3V, then it is the IR diode. It still gives off visible red light at, so beware - you can easily blind yourself, thinking it is just a dim red diode.. An LM317 is sufficient if you keep the input voltage not far above 7V. 500mA is too much for an unknown diode. Don't go above 400mA MAX (even this is pushing your luck), and the 1/4W pot will handle it fine if you put an appropriate series resistor before it (the voltage drop over the pot will be low (P=V*I) . Disconnecting the diode from the constant current source and reconnecting it while under power will kill the diode.

      Yes, you need to be extremely careful, those protection glases should be a must, as I experimented with it I broke the lens in the diode and the laser light came out just everywhere out of the diode and for a short time I got a little into one of my eyes, my heart started to beat like crazy, it was really a shock but I had luck because probably the laser isn't powerful enough without its lense. I can just say to every beginner: Do not touch it if you have any doubts, except of you have all that is needed to protect you, no matter what it's about.

    For the future, there were likely 2 additional neodymium magnets that you may have missed...depends on the drive. They are REALLY TINY magnets, too...about 3mm L x 2mm W and less than 1mm thick. They should be attacked to a small movable coil that further stabilize the LASER beam emitter based on optical feedback from the disc. This helps the drives achieve much higher speeds than before.

      Dark colors absorb heat better.

      @shmeet 7 ปีที่แล้ว +2

      Yes it does, but it may also have made the match head too wet to ignite. I would have like to have seen you put a new unpainted match in front of the new diode. Oh well.

      Still, it is something being placed between the match surface and the laser.

      How does it manage to manipulate the material on the disc if it's so weak?

    • @kv-2743
      @kv-2743 6 ปีที่แล้ว

      to maximize absorption of light to increase the heat being generated on the surface of the matchhead.

    Well if the laser diode is blue then it is a blu-ray drive.

    Great video. How fast can these laser diodes switch on/off? I have a laser I bought from eBay that has its own little circuit attached and is nice and bright. But when I try to switch it quickly (for a laser harp build) it just doesn't illuminate . Is this due to the extra circuit that came with my laser or just a limit of the diodes?

    lasers will have a focal point of concentrated energy.. did you try adjusting the distances and wait a few seconds at each distance to see where that is? It's probably fairly close up, since it is used to scan disks at close proximity

    Where do you get rid of all the electronic (-less) waste then? Can you throw it into the trash once you have gotten out enough of the electronics? what when any electronics are left over, is it okay to throw them into the trash? (small PCB's for example)

  • @jclowe735

    The red laser diode is for reading while the ultraviolet or blue ray diode is for writing which can also be used as a burning laser.

    Actually, how I look at this "infrared diode" through the gap, she looks like Mitsubishi LPC815 (red open can laser diode). Have you tried to free both diodes or just the "burnt" one? (And yes, I know that that was 5 years ago, but I'm just interested :P)
