But what am I looking for when I'm measuring the current & voltage around the diodes? Should the values stay the same or decrease by their rated amounts? Or perhaps more importantly, what should I be looking for if the circuit is *not* working? Dave

Howdy, I'm trying to make a somewhat universal LD driver and this is what I came up with. It's based on Daedal's current-regulating driver, with an extra tidbit for voltage-regulation. I'm fairly new to electronics and the theory behind it, so if you don't mind using plain English... :D The...

Howdy, I'm new here but I think you're talking about Daedal's *current* regulating circuit. It's not going to change the voltage much, just the usual loss from the 317 which is about one volt, which you seem to be experiencing. I had this same problem. Read over the thread about the circuit...

Hey, I'm Dave and just recently got into lasers after coming up with an idea. I'm a freshman in college and was thinking it'd be cool if I could make a glow-in-the-dark (GITD) poster that could be "written" on with a laser pointer to put in my dorm room. After looking around the net it looks...
