Gazoo!!!
I took your advise and purchased the AMC. It really small and great for my flashlight. But there is a problem:
I wired it up but changed a couple of things:
1.) Instead of putting a 33 ohm resistor like you did, I put a 100 ohm pot. It is wired in parallel. The reason I did this was to try and tweak the pot to see what resistance I need to get an output of 160mA.
2.) I substituted my laser diode with a normal LED.
The problem I have is that no matter what level of resistance I set the pot to, the current does not seem to reduce. The LED brightness remains the same all the way. If I set the pot to a lower resistance, the pot does get hot quickly, but even then, the LED brightness (and the current measured using a multimeter) does not change.
Any idea of what's happening?
Thanks for your time man.
