DIY laser 1w blue

hello

I would like created the laser in the video:

YouTube - DIY: How To Build A 1W Burning Blue Laser Torch!

but I do not know what component it is and where to buy
Thank you for helping me

You should try looking in the description section of the video you posted all the info is right there for you already. This is copied and pasted from styropyro's description.

Parts list:
Flashlight (There are a lot of options, I chose to "drill out the pill". You can add a bunch of extra options, like the "hot option". With the hot option You won't have to buy a flexdrive because there is already one placed in the flashlight set to the current you want. This saves a lot time. http://laserpointerforums.com/f39/fs....
Flexdrive (choose preset and type in 1000mA: http://hacylon.case.edu/ebay/laser_di...

Yes, jayrob is one of the forum members, and he made kits and heatsinks, you can try to PM him and ask if he have a heatsink for your type of flashlight host.

ok I'll see if he can make me one and send it to me

Thank you again for your support and your help because it's very hard for me to understand because I'm French

and also tell me if I'm wrong in the scheme:

Battery-> driver-> diode

Thank you
