5Mw green laser pointers are usually factory-set to a very low intensity. To increase the intensity requires manipulating the electronics inside the laser pointer. The increased strength of the laser beam, while not illegal, will now span greater distances and be easier to see when used outdoors. Anyone with a basic understanding of use a soldering iron should be able to do the modification safely in less than 20 minutes.
Instructions
1. Spread some newspaper on a work surface. Open the battery compartment of the 5Mv green laser pointer and remove the batteries. Put the batteries and the battery compartment cap down on the newspaper.
2. Hold the 5Mv green laser pointer in your left hand and clamp the jaws of a needle-nosed pliers around the front of the device. Twist the casing of the 5Mw green laser pointer using the pliers until the front and back half of the casing separates. .
3. The laser mechanism is in the the back half of the device. On it is a small screw that you should turn counterclockwise slightly, using the jeweler's screwdriver. Tightening the screw ensures that there will be an adequate flow of electricity going to the laser diode.
4. Heat up the soldering iron. Apply the tip of the heated soldering iron to the circuit board above the screw on the laser mechanism. Remove the tip of the soldering iron after 8 seconds has elapsed.The circuit board limiting the flow of electricity to the laser diode is now deactivated.
Unplug the soldering iron and let it cool.
5. Apply some bonding glue to the rim of the front half of the casing of the 5Mw green laser pointer. Reattach the front half to the back half of the 5Mw green laser pointer. Hold the two halfs together until the bonding glue sets.
6. Insert the batteries into the 5Mw green laser pointer and close the battery compartment cap. Discard the newspaper.
