im going to use 2 cr123's so i will have 6v.
1 laser diode
1 lm317
and 1 capacitor
so would it be alright if i just use these and will they give me the right voltage?
If the lm317 is used as a current regulator, then will i always have that amount of current until the batteries dies out completely
eg i will use a resistor and a pot
1.25/.0033=378ma
so will i always get that much current input until the batteries are almost dead and not like normal batts where they start to dim after a while.
thanks
