Hi folks. I've been lurking for a the past few days trying to read and learn as much as I can, but I've still got a few questions. I have a decent understanding up how the driver supplies and regulated voltage and current. However, I don't know exactly how specifically I'm supposed to dial things in for my diode (Sony SLD1239JL from StoneTek). I've put my driver together based on Daedal's nice guide and I'm attempting to include a photo of it.
I'm feeding it 6V from four AA batteries. I can measure between 45mA and just over 250mA and about 5V with my mulitmeter. I've been testing it with an orange LED for a few hours and it hasn't blown (my orange LEDs usually fry with anything much more than 2V) so it's doing something right.
So my questions are:
1. Do I need to knock the voltage down from 5V to somewhere between 2.5-3V?
2. What amount does the current need to be?
3. Does my wiring look right? (assuming I get my photo attached correctly).
