DIY DVD Laser w/ Cooling Fan

This laser uses an open can diode from a 20X LG DVD Burner. The laser has a heatsink made out of washers soldered together and then soldered around the collimator. To drive the fan off of 2 AA's i used a small boost circuit.

The boost circuit is inside the LED upgrade. You have to dismatle it carefully to get it out and use it. Heres what it looks like : http://www.accushop.at/images/product_images/original_images/MAG-LED-Upgrade-...

The tail switch i used in one of my most recent vids is just that, a switch. Heres what it looks like : http://ecx.images-amazon.com/images/I/51Kqz7TBfmL._SL500_AA280_.jpg
All internal circuits were removed and thrown away so that it is just a switch.

why do you need a heatsink when you already have the fan?

[FrigginSmift]

Heatsinks are only good until they become "saturated" with heat, once they warm up they aren't useful or protecting so i need the fan to keep it cooled off.

Is it bad if the window on your diode is halfway broken?

[FrigginSmift]

It can be.  If the windows fragments come lose they cold damage the very sensitive laser die.

Do I need the black enclosed one or the white one with 9V connectors (I have this one)

[FrigginSmift]

doesn't matter so long as you can still use it. Its a 2AA battery holder either way

[diegoribadacunha]

nice vid! Which size of washers did you use? M12 is too big and M10 way too small :-(

[xComboMambox]

Very Nice

Now try water cooling FTW!!

Jk JK its already nice how it is

[foibos899]

i would kill for this

[CHRIS90ANDES]

wtf u put a fan in that tiny box????

SKILL!

Respect dude, respect!

[crazydood135]

Can you send me instructions please?

[postopia1992]

so what is i need to make it work please help me

[FRANEDRNAS]

do you need driver to make laser work or you dont need please reply

[mrlaserguy1]

My next challenge is an Altoids smalls can with a momentary switch, 2 N sized batts, a capcitor and a 16x diode
