How to make a high power burning blueray laser! Easy,cheap and focusable!

This is a DIY guide on how to make your HIGH POWER burning BLUE-ray laser.

WARNING:
You are dealing with very high power lasers that will blind anyone in under half a secound if shined into your eyes or anyone elses eyes!


Now onto the first PIC! :D

Step 1: Parts

Step 2: Flashlight stuff

Flashlight stuff.

Step 3: The polarity

Pocket Pal PCB board polarity and what Jayrob sent me 001.jpg
Ok first off get your 9-LED flashlight take out the little metal ring (force or pressure whatever works) and then take out out all the stuff inside it, all you need is the little metal ring, the pcb board thing and the head of the flashlight, also the little shiny thing that the leds fit into and cut out the middle of it.

Desolder all the leds on the pcb board.

Now file down the edges on the metal ring.

Solder wires onto the postive and negative pins on the diode in your heatsink, put the wires through the o-ring that comes with the heatsink then you put them through the shiny thing from the flashlight and solder them to the flexdrive connection pads.

Then solder wires onto the - and + of the driver and then put the wires through the holes on the pcb board and solder them on.

Go to step three on how to put it all together.

Step 4: How to put it all together!

How to put it all together.

Step 5: Finished!!!!!!

Now you have finished your laser!

If you need more help this guide is great too! http://www.laserpointerforums.com/forums/YaBB.pl?num=1213338268/0#0

This will last WAY longer then kipkays lasers cause his DON'T use drivers or heatsinks making them die VERY quickly.

Hope you enjoy your laser!

(I did not design this laser or make any of the parts I linked to I only made this guide.)

What is the most powerful cutting laser of non CO2 type that can be built please irrespective of price from available components ? How fast could it cut 3mm plywood ? Would it be focusable ? What approx cost ?

thats pretty cool except that is way too expensive!!!!!!!!!!!!
Hello, My name is Calvin. I have a question. I own my own Crafted Wood business online and the items I make I use a normal bench scroll saw. I would like to upgrade it with a lazer saw that can cut through 3/4" wood. Any sugestions?
Epilog Lasers.
but a cheap weapon!!!
I could purchase one,but I would like to maybe build my own laser cutting tool for this purpose.
Any one out here that can maybe help?????

Is the laser safe to look at when you point it at an object like a book? Or does it only damage your eyes when directly pointed at a persons eyes?
Anything that is shiny can be a potential danger to your eyesight when a laser is involved. Be very careful, you could be blinded before you know what hit you!
So basically if it's not shiny it's somewhat safer to look at?
No, not really. ALL laser light is dangerous to the eyes-- even from laser scanners and laser levels-- so you don't want to see any kind of reflection. A non-reflective surface like cardboard or a dull white or even gray wall is okay, but keep it away from dark walls and panels for the opposite reason: anything dark will absorb laser light and can burn if the beam is powerful enough or focussed.
Then its better to use it as a weapon.
Kill someone,blind someone within a second.
Actually white or reflective items will be more dangerous to shine light at, dark objects appear dark because they absorb light of (nearly) all frequencies, including lasers, so because they absorb laser light and absorbance is negative log of transmittance, there will be less light transmitted from the incident object, meaning less light will reach the persons eyes.
Read his whole reply for commenting... "reason: anything dark will absorb laser light and can burn if the beam is powerful enough or focussed" He's talking about burning the dark object, not your eyes.

Actually it is of great use when it is used in laser cutting or in far off places to light a fire at night.

very complex not easy to get parts this is not cheap you lied and you will regret it eventally
YOU STOLE MY AVATAR!!

A comparable laser if purchased from a manufacturer would cost around $250 or more.... so yes, it really is cheap. You could cut some cost by not adding the heat sink but doing that would make it burn out a lot faster. It is also not that complex as far as electronics are concerned.

The diode page is not available. Maybe you can try these products:

Price breaks down to 15 Dollars if you buy the DIODE, and the AIXIS Module from HIGHTECHDEALZ, and if you make your own driver...

hey do you know if i can fit a homemade driver in there?

I built this laser and and had it for 1.5 days when it suddenly got much weaker and then stopped. I looked inside and saw a wire had come off. I re-soldered it but the laser is still very weak. I replaced the batteries multiple times and it didn't work. Any ideas on how to fix this?
LaserRain (author)  laserblast5 years ago
Your diode is dead by the looks of it you can order another one and replace and it should be at full power again. May I ask how many milli-amps you had it set at?
115mA
why would it die after 1.5 days?
two words. cheap. parts.

 the link for the heat sink is broken where else can I get one?
 this is a cool project, but in my book, $80 is not cheap. Kipkay has easier ones, and you can get his diodes from cheap, broken Xboxes.

This is pretty straight forward.  Thanks for the info.
does it burn through stuff?if so, then i want it!

dont diss kipkay he does gr8 instructables and his projects are supposed to be easy not complex

 UGH!!!! ive spent the last 2 hours trying to find the dang heatsink!!!! no avail... someone please help me!!!
BL1NDED4 years ago
 i am having a lit of trouble finding the heatsink you mentioned off the sight you posted. it just brings me to the forum home.
randone4 years ago
could you use tape because I do not have a soldering iron and I do not mind taking it apart every once and a while.

Also, how many mW is the diode?
Mr. Waffle5 years ago
DO you NEED the heatsink, and if you do is there an alternative site to buy it from?
