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

In this episode of HACKED! I will show you what I salvaged from an old PS3 and solve the comment mystery from my previous laser diode video which says that a Blu-Ray laser diode can burn things.

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

[Forssa]

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).

bluray disk player not enough beam to burn the matches, try bluray disk burner laser diode

Amazing video as always! Are you Topper of your class in academics?

[daaronson]

Do a video on all the calculations you use. I'm going to school for this but they still don't cover some of the calculations you use. I also figure anybody who wants to do the same project can tinker with the calculations and get a different result.

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.

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.

GS: hey power supply do you feel like turning on?

Power supply: oh sorry no not today

GS:😑

Your channel is like the porn of electronics that every one loves your videos, your channel and you. And also watch your video again and again :) <3

[tuskiomisham]

when he uses the read blu ray diode, not a writing blu ray diode. lol.

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.

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

[Mosfet]

Great video! The PS3 diode I don't think has the ability to write. If you had a BluRay burner maybe better luck? Would be fun to see.

[BrandonPrintiss]

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

[DiyEcoProjects]

ooo... that 12v fan nice. That woud make a good laptop cooler pad.

I like you videos, very well explained, thanks

[rich]

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

[JohnL]

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.

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.

[ggeasy]

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..

HDD! you can format it, and uses for other hard drive usage!
