How did you break the pot off.?Your right, the top of the pot is missing! but i dont understand.. it keeps outputing 1.5A xD
I've never had any trouble with UltraFire or TrustFire batteries. Whether it's 3x10440s, 2x16340s, or 1x18650 - running them all the way up to 1500 mA, I've never seen any battery issues.UltraFire and TrustFire batteries are not good to use for lasers being driven over 700mA.
hey. i did set the current and the pot was alright. but dont understant one thing, why cant i use the laser as a test load? doesnt the test load simulate the resistance of the diode?The biggest concerns I see here so far are:
1) Without a pot, you cannot adjust or set the current
2) Without a test load and a DMM you cannot measure the current unless you wire a DMM between the driver and the diode.
What this means is that we have no idea what current is being given to the diode. Until we can set and measure the current, speculation is useless.
Do you have a DMM?
