I have been reading posts for about a year now on this forum and decided its time to start asking questions now that I am gearing up to actually build something. So the question:
I was on DTR's laser store and saw that the diodes sold there come with either a Microboost driver or a X-Drive. I was thinking about using one of the M140 diode modules. Now, I am trying to figure out a way to make this a two for one deal on this laser and end up with a crazy burning monster, but with a power selection switch to turn it down to about 100mw output. Would it be possible to do this? I haven't found any documentation for either driver saying how to set the mA output. (The pdf for the Microboost has suffered link rot) I read about adding a resistor between the driver and diode, but I want to avoid this because its a good way to waste power and I want this to not be a completely ghetto project.
I know the drivers usually have a reference resistor on them. I was thinking that by wiring in a switch I could swap between one resistor value and another to change it from full power to low power. I just want to know what this reference resistor might be for each driver, or if this is even a good idea in the first place. Any help is greatly appreciated. :thanks:
