Laser Pointer Plug-in MOD

The first thing I did was rip the silver backing off to expose the guts...it's just glued on (be careful not to mangle it too badly). Unscrewing 4 really tiny screws gets the board out. (Theres a really tiny spring that I lost almost instantly, not sure what it does as I didn't bother looking or it and it still seems to work ok.) I pried the microswitch off the board and put a blob of solder in it's place to jumper the four terminals under the switch...this way the thing is always on once it's plugged in. Then I soldered a lead to the positive upright terminal and another to the flat negative terminal (the board is marked). I dremmeled the battery holder to allow my leads an exit, and put it all back together with the leads hanging out the battery access door. Putting the door back in made it all nice and tight (hehe). Solder the leads to the AC adapter and remember not to look at the beam with your remaining good eye
