I have made a lm317 current driver(Thanks to Daedal's handy tutorial)it puts out 1.5a just what i need but the voltage output is 3.0-3.5v and the laser diode i have says Typical operation voltage is 2.2V and Maximum operation voltage is 2.5V so does anyone know a way i can drop the volts to around 2.5v? I was thinking use a diode but i don't know one with a low current drop.
I used the lm317 on the free laser diode and output voltage was 7v so why didn't it blow?
Also i am using a UltraFire LC 18650 2400mah 3.7v .
(Link to laser diode:One extra high burning power (1000mW-1500mW) 808nm TO-5 9mm laser diode + Gift* | eBay)
