Do these materials are available in store in spain?

1 LM317 adjustable voltage regulator
2 resistors 10ohm
1 25ohm POT
1 IN4001 Silicon Diode
1 35 volt capacitor 47 Mf

I use this manual http://youtube.com/watch?v=BI7iuBze5I8

And another question, how should connect the diode, and must have laser module?

Using a stack of 6v, any information before doing so?

You can order most of it online if you search, or www.ebay.com
 
100ohm multiturn pot would be fine there are usually some on ebay.

But putting that is 25ohm, does not matter? I think 25ohm to 100ohm is much difference, if you see in the video puts 25ohm
And I have to use batteries, and how many?
 
All that will happen, using a 100ohm, is that the starting current will be lower when set at full resistance.
As this is a red you need to get to 7.2v so 2 X RCR123A's will do the trick. You can get them from Deal extreme.

I can not use batterie 6v?

You can use 6v but as soon as they begin to sag the regulator will stop doing its job properly.
In simple terms 7.2v = 3v for the LD, 3v for the regulator 1.7v for lots of burning time and fun ;)

One alternative is to use an LM1084IT-ADJ. I had a bunch of these sitting around and used one in my first 2 cell CR123A MXDL laser.
The LM1084 is rated for 5 amps and is pin compatible with the LM317. It has a lower dropout voltage (approx .9 volts @ 500ma). At $3 each, they are only slightly more expensive than an LM317.

I'm planning on using an even lower dropout regulator (LT1764) for my current open-can project that will run on 3AAA's in DX flashlight sku.1442
 
Building this circuit:

With a switch like this:

How'm the diode, if food cell 6v?
He would put module Laser DX
 
I noticed in your picture you are using a 9V battery. That won't have enough current, unless it's for a Blu-ray.
 
Says 6v for laser red and 9v blue-ray ...

I had assumed that as you were using 2 X10ohm resistors you were building a red???? If so your 9v battery will last for a couple of minutes at full power as they do not have enough capacity (ma/hr's) to maintain the output.
I suggest you go for 7.2v as suggested previously when you come to test the circuit before fitting the LD.

Ok, first I would put 6v battery and then when I come I would put 7.2v, are there dx? What is the link? And the charger?
