I've been messing around with a circuit simulator, and I have some more (very n00b) questions if you have the patience ;) 1. I'm confused how the resistance bypass circuit is supposed to work (h***://laserpointerforums.com/forums/YaBB.pl?num=1198812822/11#11). Placing the 20 ohm resistor across...

likewhat: My laser diodes don't have photodiode monitors (only anode and cathode pins). They will be run below max power at a low duty cycle however. GreyFox: Thank you again! Setting the range of the LM317 with static resistors is very important if the LM317 is under "remote control". I've...

xanatos: Unfortunately I need all lasers to be on and at approximately the same intensity simultaneously. I agree that I will need a driver circuit for each one. The thought of killing many at once is truly horrifying, lol. Which I why I want to learn as much as possible about the theory behind...

Thanks very much for your input. ajohnson: I agree that each diode will need it's own driver. Norm's laser diode driver with modulation looks very good, and it's something I will investigate further (although it's too expensive to buy 50!). I have been studying modulation and op-amps over the...

Thanks for your reply! I can see how that could be a problem. I'm afraid my project is a bit more ambitious than I originally stated. I ultimately want to control the brightness of many identical laser diodes (50+) using a single control. I am at a loss on how to even begin to think about...

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...
