Great Work!
There are many Laser pointer
 on the market, so you must have a clear observation and sufficient 
basic knowledge before making a decision. Laser enthusiasts choose laser
 pointers from reliable suppliers. Knowing what you need is always a 
good choice.Both the cd on the laptop or the cd on the laptop can be 
filled until the laser head becomes obsolete or obsolete. You need an 
old DVD disc (with a brand new electronic counter, MCG will not stop 
you), preferably 16X, of course 8X is also good, but the power is much 
lower, generally only 140mW, much less power.

Of course, the first step is to dismantle the beams. Turn the light 
actuator over and use a Phillips screwdriver to turn the screwdriver 
into four corners. After opening the lid, you can see two integrated 
circuits: one large and one small. Then pry open the locks on both sides
 of the big board, remove all the front and rear cables, and then you 
can pick it up. The so-called bald head is located at the bottom of the 
board, between two metal rollers. There are fixing screws at both ends 
of the sliding rod. You just need to unscrew the bottom of the reptile 
on the left. Remove the smooth headband and remove it from the optical 
drive. Turn off the flashlight, remove the light from the tube, and 
restart the head of the laser module that was just taken out. If the 
lens is a plastic bulb, it must be removed to avoid being melted by the 
high-energy laser. Finally, put the lamp back in its original position 
and the battery back to its original position.

Great Work!
