The pot should be 100ohms max
The resistor you need to work out for yourself. It will set the maximum current available to the LD, use search to find the max current then go to the driver page on my website (link below) use the simple sum to work out your fixed resistor.

The capacitor needs to be 10microfarrad 16vconfused all these variation of pots, resistors, and capacitors

There are very good tutorials on here that take you step by step through flashlight builds, you need to spend some time looking for them.It would be nice if someone could explain the WHOLE THING about making these into flashlights.And i mean EVERY little detail

My guess is that the pre-installed LD is dead, swap it with the one you know works....remember to short the cap before removing and adding LD's though.Ive set up this driver to a 'T' and when i hook up the pre-installed diode I get a very faint glow. However, when I hook up a diode that i extracted from a DVD burner to the exact same driver, it shines brighter than something I would want to look at
