Default Open can driver.

Hello everyone
I was looking at the ddl circuit page and it says that it is for a dvd burner diode and outputs 200-250ma, im prety sure a long open can can take up to 420ma with a heat sink. What modifications do I have to make to the driver if i am going to run a long open can at ~ 420ma using 2 CR123A (3v).

thanks ;D

Use a 3 ohm resistor instead of the 2 10 ohm resistors and get rid of the pot unless you want to adjust the current to run below 420mA.
And you can't use two 3v batteries, you need 2 3.6v batteries for this driver.

Can you recharge 3.6v CR123A recargibles on a charger for 3v CR123A?
The specs of the charger are:
Input voltage: AC110V~240V
Output voltage: DC4.2v - 300mA

Also how many watts should the resistor be?

Yeah, you can use that charger.
1 watt. I got my resistors here, it's only 70 cents for 10 resistors.

Do any of these dvd burners have long open cans?

Yup, LG should be good, but don't get any that say, "double layer" I don't remember where or when I saw a thread saying those had weird diodes in them. :-/ Not really sure if these are it, but just to be safe, get one that doesn't say that.
