We have been doing some substitution. The pot should adjust up (take the cover off the power supply).

Hello Mr Aixiz =)
I recently ordered one of your 50 mw unit , and received it today (fast shipping, thanks !!!!), but i think there is a little mistake on the unit :
The maximum current flowing to the diode is 460 ma , whereas other unit can go up to 700 mA (with the potentiometer), the same as my other green laser pointer (rated at 30 mw) , plus i have a 30 mw label on the side of the module (witch are not the same in the photo in the auction, like

I think i got a real 30 mw green, instead of your lovely 50-80 mw. It's is possible to resend you this unit to have an other ? i have not modified the laser module to check mA.
Thanks for your response !

Mike, you would probably know a lot more about that than I would. I'm still trying to figure out what the square filter is for, and why mines burned in the middle.
DON'T FORGET to insulate the 317 from the box, the outside of the laser is +, and the 317s tab is OUT. If you forget to insulate it, it will die real quick. If you have a bad driver from aixiz, the big transistor on the heat sink close to the output end has an insulating kit on it. You can just take out the screw from the transistor, and use it, and the heat sink with the small insulator on the screw and the heat transfer insulator behind the transistor. when you take it apart, you will see what I am talking about. This heat sink really isn't big enough for the lm317, but it will work, but after a few minutes it will start to overheat. I fixed that by drilling a hole on one side of the heat sink and tapping it, then using heat sink grease on it and a screw to attach it to the side of the aluminum case. Now it doesn't overheat after 15 minutes on.
