Compatible flashlight boost converters, cheap 445nm drivers

[ReNNo]

Many of us prefer low-budget laser builds instead of throwing ~30USD+ for "proven drivers".
There are few 445nm laser builds that use cheap boost converters from flashlights.
First driver that is proven to work with 445nm diodes is one with "NJG-18" mark on it.
This driver can be ordered on DX:
DealExtreme: $4.26 3W 19-Mode Universal Regulated Circuit Board for Flashlights
Or Kaidomain:

But there are much more cheap flashlight drivers on market and it would be better if we can make bigger list of compatible drivers.
We can find many kind of drivers... different sizes, shapes, different mods supported, different input voltages, different output currents and sometimes we need specified driver for specific use.

Please use this thread to post your experiences with different cheap drivers so we can make bigger list of compatible flashlight drivers that can work with laser diodes.
Please post high resolution pictures that can tell us more about chips, capacitors, coils, resistors and pots used in specific models.

Will update with pics of driver in 30 days when the new flashlight arrives.

Hey, I was asked to add this to this thread.

If you are looking for a driver that puts out a steady 1.2amps this is the driver that i have been using for a couple months now. Iam running it off 2 CR123A 3.0v lifepo4 cells for full power and iam getting 1167mW and if you put in a 18650 cell it still works but not in full power. Iam getting 215mW with a 18650 cell.

It can handle up to 18v input but i would not pass 12v or ever 8.4v because its not needed.

The Driver only coast $1.99.:wave:
DealExtreme: $1.99 18V 5W Cree Circuit Board for Flashlights (16.8mm*5.5mm)

Check my thread out for more details.

I ordered 3 of these 18V 5W Cree Circuit Board from another site, and hopefully their shipping beats dealextreme. I would still put a capacitor on the output to stop any stray current spikes.

Hey guys I thought i posted this part over here from my other thread but i forgot to so, I also want to mention that here is the site where you can get similar to the boards i posted above that you can put a pot on them to regulate the current. Ive order some about a month ago and they should be here very soon.

Here is the thread on CPF on how to put a pot on them:
Desperatly looking for driver (updated kennan driver?)

Here is where you can get those drivers at:
http://kaidomain.com/ProductDetails.aspx?ProductId=1640

Edit: Very easy to do and you can get 2amps out of it. Her is the data sheet for the IC >http://www.axelite.com.tw//Products/AX2002-V1.2-20080729.pdf

Also I want to mention that suppliers tend to some times change the board up a bit so Lets hope they are the same as they are showing in there Picture and in the CPF thread.
