HACKED!: PS3 Blu-Ray Laser Diode || Simplest Constant Current Source

[@riperchetobg]

its because ps3's blue ray is read only, you need read+write to be able to burn stuff

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).

[@RafaRdzanek]

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).

I really enjoy that this isn't an electronics account that makes videos for those afraid of math. I enjoy what math can do for electronics design and how it can help. (Not to mention how it helps). You also don't make it all about it though, to reach the side of hobbyists who don't like it. They'll like it eventually though.

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.

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.

[@AtomsLab]

Thanks for that tip about enabling the PS3 power supply! I had one sitting around unused for years, and thanks to you it's now powering my laser engraver :D

[@AtmelKiller]

+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]

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.

[@freedom_aint_free]

Great video; try to use the UV laser to cure some epoxy resin, or other UV curable resin, the chemical mechanism of IR and UV reactions in materials are way different, but remember the simple quantum relationship: Energy of a photon=Planck constant*wavelenght/velocity of light in vacuum.

[@GruntW0rk]

Would be so cool if you made a laser solder gun. You could use a normal lower power laser to aim and with a button press, activate the more powerful laser that melts the solder.

[@ggeasy8499]

It seems so easy when he is soldering..when I am soldering, even though I have some mechanical metal clips to hold my wires and a magnifying glass, my hands were still shaking like my 80yrs old grandfather..

[@morgan3447]

there is a huge difference between getting a phosphorus match to ignite and to reach the ignition temperature of wood

[@wirebrushproductions1001]

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.

[@SPLPuroOne]

[@vinolicam4140]

youru content is astonishing! watching your videos I feel like I could build a Mecha

[@JohnL90808]

The unit is only for reading, the module is a combination of 780/650/405 nm diodes at roughly 10-20 mW sometimes at 50 if you're lucky.

[@CustardInc]

It's only a class 1 laser product because the laser isn't supposed to be able to harmful to anyone if the device is used as intended. If you start taking things apart then it's going to be more dangerous and might have a different classification ;)

[@DiyEcoProjects]

ooo... that 12v fan nice. That woud make a good laptop cooler pad. I like you videos, very well explained, thanks

[@BrandonPrintiss]

Have you ever messed with the bluetooth on the PS3? I'm curious if that can be used for other projects.

[@RinksRides]

it's the wavelength, red is closer to infrared, which is heat, and why IR/RED LASERS are more apt to cutting things.

[@chrrtz_builds2018]

You sir have some really good friends.

[@BrendanOrr]

The red light of death could mean that the board just needs reflowed. The BGA of the chips on the original fat-style PS3s have a tendency of disconnecting. At least was the case with mine.

[@BavarianM]

Wrong It’s nec Tokins

[@TrollFaceTheMan]

Cool video, but that PS3 probably would of been salvageable if you just reflowed the CPU and GPU chips. Fixes the YLOD a majority of the time. I have a old ps3 power supply like yours I might do the PSU mod that you did as it seems like a good way to power 12v high wattage LEDS. Thanks for the video!

[@thenoid5131]

great video sir did you go to some electronics school to learn all and for how many years, its always good to know what's behind the magic

[@arnislacis9064]

You need to extract laser diode from computer's Blu-ray writer/recorder. It's possible that the burner diode have 500 mW or 1W output power.

[@rich1051414]

Good Job. If your power supply is upside down, all the electrons will fall out.

[@marksierra3522]

It will work, but you gotta get that point a whole lot more focused. I bought a laser on ebay that I assume is in the 20 to 40 mW range and I'm able to light matches with it

[@slashpointo]

summer is coming, can you please make something that would be useful in a few months

[@fernylloyd1975]

He made the cooling fan project. Maybe he should make AC out of a car radiator. Just put ice on a cup and a fan at the top that sucks cold air out of the bottle. A laptop fan.

[@alchemy1]

I took 6 dvd players apart. At the end I managed to have just one laser diode that worked. Just why none worked except one, I have no idea. This is the only video that doesn't warn about shorting out the LED. He simply cuts the ribbon and use solderig iron and removes the tape. Then furthermore tries different connection pin to see which one lights up the LED. No concern about shorting anything.

[@dylanfrost191]

The power supply already had banana jack outputs without a mod? That's awesome

[@driveitbreakitfixit7496]

+Lieutenant Frank He just coated it in black to make it easier to light

[@MrWitchblade]

Love the maths! I keep killing diodes, lol, infra-red ones burn well.

[@HighVoltageMadness]

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.

[@eW0LF]

Some PS3 units have 32A PSU. You should check that - I used one to power 3D printer. You shold use the PS3 case and build a PC in it.

[@eW0LF]

+ELECTRONTHORP It doesn't come with the fan. It looks the same as the one Scott used in his video. I remived the PSU from its case and placed a 12cm fan on it. It should not be used without fan-its ok with small loads,but anything above 10A for long periods makes it really hot.

[@mrkiky]

Those guys have no idea what they're talking about, blu-ray reader diodes can't output more than 5mW. You need a writer diode to burn. There is an exception though, the PHR-803 (iirc) found in the xbox360 drive that for some reason can be cranked up safely to around 100mW.

[@tenpotkan7051]

That is some really high-tech calculator.

[@tiger.98]

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

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

[@zedius24]

What about your lm317, didnt it heat too much without radiatior? Moreover according to datasheet max current is 200mA for this transistor. How did you manage not to kill this guy?

[@lucasn0tch]

He was given the PS2 compatible version of the PS3, so that explains why it doesn't work anymore

[@RenoxMTA]

Lucas and Pikachu No its not a BC. I know that because its 40GB and it doesnt have the chrome finish on the front Most of the phat ps3s get YLOD not just the BC ones

[@НиколаНиколов-м1л]

its only for reading not writing

[@Xenro66]

Nikola Nikolov Oh, I didn't know that... That'd explain why it's so weak

[@НиколаНиколов-м1л]

Xenro66 yes if you take laser from blue ray writer it will be much more powerful

[@power-max]

Nope. The simplest constant current source would be to get a JFET and connect the gate and drain together. This will allow the JFET to conduct a certain about of current, there is a special name for that amount of current, simalar to "saturation" in the BJT transistor.

[@greatscottlab]

+Power Max But it is a small current.

[@Jilocasindragon]

I really like your videos but I never got my head around why people call this "hacked". It's probably for recognition reasons, so people will click something thats got " hacked" in the title, even though you basically just salvaged some cool stuff. Turning the power supply on with two resistors and testing the diode is barely hacking (or modding) something. Even tho, just a random thought. You don't need to use buzzing, fancy keywords with exclamation marks, man. You're great. :)
