Re: PWM Laser

I have fixed the Laser problem. Turns out when we switched it to be inverted that was causing a problem with the whole setup. I put the O-scope on it and see how it was inverted. So when I was asking for full power it was basically shutting off. After adding logic level converter and going back on t...

Re: PWM Laser

Honestly I don't. I did read that it should work with TTL voltage from 0-12v. If that is true I have no idea. But when you put 12V to the PWM line it turn on instantly starts burning a hole in stuff. I am going to get the scope out and see what is going on. Thought I could pull this off with just a ...

PWM Laser

I just bought a laser that has no information with it. I have it hooked up and can turn laser on and off. But it doesn't seem like the intensity is changing. Also in one of your post you said you changed the duty cycle and a couple other things. What kinds of things did you change?
