How to make a powerful burning laser for CHEAP!
Here is an example of a good heat sink for a laser. One like this that may cost 50 dollars or more.http://www.ebay.ca/itm/12V-Industrial-638nm-200mW-Red-ray-high-power-Laser-module-with-Fan-/231078315625?hash=item35cd574669:g:86QAAOxywOtSZSYK
A good idea is to add a really good heat sink to the lasers. Some cheap 250 mw burning lasers from e-bay do not have this. So without a proper heat sink the laser even though I added one only last 4 hours max.
yes, PLEASE listen to this about how dangerous lasers can be., I am now permanently blind in a small 1mmx1mm up close spot that progressively gets bigger the farther away at a max of 5mm. This was caused not due to stupidity but a freak accident. Sadly its dead center of the eye almost but its been almost 2 years. it seems to hopefully be getting better, but I doubt it. PLEASE take lasers seriously. They can be a fun toy but can be very hazardous. You've been warned!

Form any computer or device that says it is a dvd drive/ CD burner (literally means burn)
You should be able to go to a goodwill or somewhere similar and find an old one. Or just buy a cheap one from Walmart.
Also, an old computer tower if you have one.
WHERE DO YOU GET THE OLD DVD DRIVE??? I NEED TO KNOW!!!
is there a place to buy the laser diode?
I think that a led lamp is good too. Just make sure that its resistant is 10 ohm. Or a wire with a higher resistant. Or dont use a resistor, but you'll fry your diode fast
cant understand circuit daigram....?how to join positive and negative connections.and can i find laser dioed frm computer dvd drive?pls help me
If it works for the Chinese.
I used a lense that I found in a dvd drive.
I got my laser to work, but it doesn't seem to burn anything. Suggestions ?
Sorry JesperK I don't have any confidence with the information from Wikipedia. I am a electronic technologist and even if I looked something up about electronics it doesn't always give me the right answer. The last time I was to my ophthalmologists for a eye exam I asked her about the danger of laser pointer and if I need safety. And she told me as long as I don't look directly into the beam I will be alright. But you can ask your eye doctor ,and if they tell you something different please let me know. Thanks
Please be careful Mayurnath5
Is there anyway to focus the laser to a beam or something like that because it looks like a blurry dot, but if im mistaken i ask if anyone can tell me.Thanks guys
