was just looking at videos of builds and seen a guy using a diode off a 9v with only a resister and switch in series. I'm sure everyone seen this. I appreciate the value of my diodes (after one death) too much to do this, but was curious about it's life span and mw on this set up.. If you can call it that.

DON'T LISTEN TO KIPKAY !!!
That Setup will kill the diode either instantly,or in a matter of time.
you need a driver to protect the Diode from the Voltage spike and to limit current to the diode so its not getting blasted with Ma's.
Read up on this forum and youll learn alot.
Please Buy a Rkcstr driver here at

actually waiting on a lava2 but will probably buy a rckstr as well. Thanks for the link!!

No problem.
Any of the fine Drivers that the guys of LPF Make will work perfect,and you can even use the drivers for other applications like for fans and other Nik knacks.

Good job Wes!

kipkay isn't in it to help people, he is in it to get money, and if he said the real and logical way to doing things it would be too hard for many people and they would not show others which means less views for him and less money for him!

sounds like a nice guy!!

I wish I could get paid to lie to people :-[

Laser Diodes are current driven not voltage driven...
A resistor is a current limiting device... but its current limiting value is
dependent on the input voltage..

Here's a scenario..........

One day you use a slightly used carbon 9Volt battery and figured a required
resistance of "X" that gives you say 100ma of current through your LD
(just at max current for your LD)... great it works.

The battery runs down and the LD gets dimmer... you install a fresh 9Volt battery
(very fresh alkaline) and poofff you blow your Laser Diode... why???

The current limiting resistor saw more voltage and let more current get to your
LD. End of story

The LD Drivers sold here by reputable members are immune to excessive/varying
input voltages and limit/stabilize the current to the LD (as long as the specs of the driver are met).
