Hello everyone. I think it would be cool to control the output of multiple lasers simultaneously using a single control. But being a n00b, I am short on ideas on how to implement this, if it is even possible (well, anything is possible I guess).
In Daedal's driver design, the current output of the LM317 is set by a potentiometer (optionally). So the brightness of the laser can be adjusted by turning the pot. If the power supply voltage was high enough, would it be appropriate to add additional laser diodes in parallel (within limits), and set the output current of the LM317 to ~0.15 A using a single pot (for example)?
Or if I'm completely wrong, are there any other ways that I can accomplish this?
Thanks very much!
