    The laser in the PS3 is just for reading the disc, so it is only good for up to 50mA, at most (more safe at around 30mA).

      Forssa1 Dual lens PS3 sled found in newer models is capable of outputing more than 50mW - I cranked up mine at 100mA and burnt some plastic and ignited a match (ofc at this current lifespan of this diode is pretty limited).

    Great Scott, just from watching and listening to you're videos. You have taught me so much more! then reading ever has from watching your videos about electrical engineering and setting up circuits. I am amazed you are not out there compared to other channels you teach so much and draw out diagrams detailing how you will connect resistors to pcb boards etc. Also showing the math you did to get the numericial value for how much electricity would be wasted is amazing.

      Vpot=Vtot*X/(Rres+X) // use voltage division to find Vpot
      Ipot=Vtot/Rtot // current is same in series so use total resistance and Vtot to find Ipot using ohms Law V=IR
      Power = Vpot * Ipot // Power = V*I for any component
      Power = (Vtot*X/(Rres+X)) * Vtot/(Rres+X) //plug everything in
      Total allowable power needs to be under Power rating of Rres and the POT's Power rating.

    You can get mostly safe laser diodes from devices that can only read optical media, but much more powerful ones from devices that can write to it.

  • @wirebrushproductions1001
    @wirebrushproductions1001 4 роки тому +2

    I'm afraid you are mistaken about killing potentiometers. Usually, the issue is not dissipating too much power. The problem is driving too much current through the wiper. This can produce a very small, localized burn on the resistive element, and at that particular position the pot will appear to be dead.. The maximum safe current depends on the specific pot - but it's not usually very much.

  • @AtmelKiller
    @AtmelKiller 8 років тому +1

    +GreatScott! You should check the beam pattern of the laser diode. I had 8 laser pickups to play around with and killed every single one with ESD. Even while grounded with an esd wriststrap and earthed soldering iron. Those 405nm diodes are very fragile and even more sensitive to esd than other wavelengths. You should look at the beam pattern if its a constant bar of light. If not you most likely killed the diode. Dead laser diodes usually emit a random splitted pattern or even no light from front surface, just some reflection of the substrates sides. + they often emit a yellowish color on the sides when they are dead.

    • @AtmelKiller
      @AtmelKiller 8 років тому +1

      And your diode looks pretty dead in the Video. Do not exceed approx 50mA or it will die. Those diodes are only for reading and not burning discs. They usually have about 5mW of output power.

    It looks like the violet laser diode is damaged because the output is very dim. Also its possible that the playstation does contain a burning violet laser diode, it might be a read only laser diode that isn't able to burn things. I took apart one and the diode did work but it only puts out about 15mW or so not burning.

Turning the power supply on with two resistors and testing the diode is barely hacking (or modding) something.

      @TrollFaceTheMan 7 років тому +1

      It's not that the solder spots conglomerate, it's that they expand and then crack as they cool separating the chips from the board.
      If they did all just stick together as you say heating it back up isn't going to do much of anything to fix it because that won't separate them, in all honesty heating them to molten will most likely make things worse.
      If a point is ever reached that they do completely fuse to one another then you need to completely remove the chip and strip it of all solder and do a fresh application.
      The reason why heating does work though is because as I mention prior the connections crack to due expansion and contractions of the solder, heating however melts this solder and reestablishes these connections completely.
      If you keep having issues with your chips after doing the repair it's likely that you got a bad PS3 with really dry solder points. Or didn't put back on thermal paste, or enough of it, or good enough quality thermal paste.
      Or that the brackets that screw onto the CPU and GPU were not tight enough as those are needed to wick away most of the heat. but also keep pressure on the chips to prevent expansions and cracking as I mentioned prior.
      Not saying you did this, but it's common for reoccurring systems

    Can it cut through thick metal, say 3mm or 2mm thickness?

    You can turn on the ps3 psu just by shorting 2 of the 5 wires together, I did it on mine, and there are other documents on it too. You didn't need to use the resistors. I forgot which two wires but googling it will reveal how

    there is such a thing as a dead ps3, but there is no such thing as a dead snes. mine still works!

      Yep, I replaced the coincell of some of the cartridges. I have gaming nights my friends come over we have some beer and play snes the whole day. nothing like a good snes gaming night.

    This is a low-power 405nm laser diode,maybe you need a high-power 445nm LD,such as NDB7775 NDB7A75,NUBM07,NUBM08.M08's power can reach 7W!

    To obtain a really high powerful laser you need to use a BD writer, not a reader (it's the same of DVD).

    I'm genuinely surprised that diode wasn't able to ignite the match. Maybe on later versions of the PS3 (or possible PS4) there could be a more powerful diode.
    P.S: Jesus, I made that comment 10 months ago now ._.
