There’s a certain disadvantage of the LM317 solution. During power-up those regulators produce high pulses which could destroy your laser. So do you provide some means of overvoltage protection?
I guess i would prefer a solution with an active step-down regulator or something similar.
just a lm317, inputvoltage 5V
i killed the diode, cause i needed the case 4 a dvd burner diode, so i’m not able to say how long the diodes live at such ‘high’ current
From my experiences, those little devils are quite sensitive to overvoltage. Did you limit the voltage at all? Did you experience any loss in power during the lifetime of that diode?
p.S. love your transformers as well. where’d you get them? Need a supplier in the area of Dortmund
i know, but i can get lots of those diodes, so what do i care? ;D
the next few weeks i´ll build some real drivers with analog modulation ^^

There lots of tutorials, just pick one
That was cool. How can I build one?
