Its a Constant Current source from the battery driving your Laser Diode.How do I use the lm317? I saw this circuit and I am curious on how the lm317 controls the voltage and current. Does current flow from the adj pin to the vout pins or the other way around?
I'm totally surprised that all of the OPs threads on this topic haven't been shut down. From the electronics knowledge he's showing, doesn't any one see the folly of helping to build a "burning laser"? Almost every one of the posts, he asks about overdriving the module, I only see this with a bad out come.Gadersd, I told you in your duplicate thread on this topic that your image was too small and that the circuit was a constant current arrangement. It's not cool to start multiple threads and waste people's time with the same thing over and over.
This thread of your's is barely different as well. Why not start a single thread on "Laser diode driver" and keep the discussion in one place?
