I have run harvested reds and IR's from LG burners with no regulator with no problems. I typicaly use 2x33ohm resistors a cap and a diode for polarity reversal. If I do the same with the blues, and restrict the current, what type of voltage should I use 4xaaa for 6v or higher? I was also thinking of using some LR44 button cells instead, seeing as the current draw for the diode is 50ma. Using Gazoo's circuit is probably the safer bet, but its too bulky for what I want to do. If these diodes can handle up to 9v do I have to worry about voltage spikes when using 4 or 5, 1.5v cells?
