Very impressed by your build LaserAdct! It seems simple and fool proof. I especially like the sunken mounting bolts. Would you mind taking the time to outline any pit-falls in your construction, or any setbacks you encountered? Im in the process of building an RGB scanner system and I think...

Your local power distribution substation :D :D Sounds weird Firsh, got any links?

I think its clear dark4ngels objective is to create something that gives the impression of a light-saber, not to amass a load of comments concerning the impossibility of the real thing ;). You're lens that constantly changes the beams point of convergence does interest me though. I was just...

You are right of course, and indeed for Sourcegeeks resistor values this will have a large effect. However, if he were to choose his resistor values carefully he could minimise this to a large extent without employing your ideal, yet component requiring, fixed voltage reference. If the...

Ya na he's got the right idea with the voltage divider. You're making the mistake of using your V- as ground with your opamp resistors and LEDs. Go back to your schematic in post#16: The two series resistors running parallel to your voltage source; in the middle of those is your virtual ground...

Seems like anselm's gettin a bit of a hard time ;) I'm along his exact train of thought though. PWM seems more than plausable to me, however pulse speed would be critical. I think it fairly unlikely that the pulse frequency would ever be a multiple of the scanning frequency for an extended...
