Okay well i decided to test this again WITH a new battery and now it's brighter? it could burn tape as well? does that still means it's fried?
what batteries are you using?

How many laser diodes have fallen victim to your "tests" try a lower voltage laser. And maybe next time don't post 40 times in a row.

Lol I normally get between 2 - 5 people emailing me on a daily basis, asking why their respective diodes without drivers are not working when powered up.

Doh.

I am a little bit confused about this because you are posting too much. Did you use a driver when you tested it again?

okay sorry next time i'll provide more detail in a new post.
I used the first driver, which was the '18V 5W Cree Circuit Board for Flashlights' Driver.
I don't have the O-like Driver and i know it would require only one 18650 Battery.
But for the driver i just used to test, the laser seemed to be brighter than before? Would you recommend me purchasing the O-Like Driver for this build instead?
Also a question about the driver i am using, if was to use 2 18650 Lithium Batteries would it become brighter?
I am still a dumb ass with these things i admit, but what is the title i should research?

Charge all batteries before using them. That driver will need 2 li-ion batteries in order to function properly.

And do not run the module without a heatsink otherwise you'll fry it.

You can find a search bar at the bottom of the page. Use it.

Okay just to finalize things: 2 li-ion batteries will bring it to its maximum output? (for the driver i'm using)
If i purchase the O-like Driver would it perform at its maximum output with just one 18650 Li-ion Battery?
Sure do have a heat sink, would applying thermal paste be necessary?
Okay fair enough, thank you.

You need to do a lot more reading. Judging by your posts, you dont seem to understand anything but its not bad. I admit that I the same back then.

The DX driver need 2 Li-ion cells in order to function properly.

In most cases thermal compound is not needed.

Take you time and read around. There are a lot of helpful threads like this one: http://laserpointerforums.com/f51/i-want-build-laser-thread-52972.html

Learn WAY more. This sounds like an impulse. Keep those under control. If you don't know much then why did you get it in the first place?

yea, maybe try buying a 10$ 100mW 405nm laser diode off ebay first...wont cost much, and you can practice setting a driver+soldering it to your diode. if it works, then cool, you have a nice little burning laser. If it doesn't work, then oh well, you are out like 30$. But if you mess up your 445 diode, then you are out much more money..

before you start a build, always do some research. The google search bar at the bottom of the page will help you a lot. Good luck :)

Only if they're fully charged. That is why I said earlier to use 3.

Yes, but only if you can figure out how to adjust it right.

Sure do have a heat sink
Keep your finger on both the diode and driver. Use the heatsink on anything that starts getting hot.
