In this instuctable I'll show you how to make a powerful handhold laser. Almost all parts are easy to find online. There are only one part that must be produced by a lathe, everything else can be made with ease.
Warning: These lasers are powerful enough to burn your skin. In other words, they are powerful enough to take out an eye instantly. Always use protective goggles.
Step 1: Acquire parts
We need a shell for the laser with a lot of power. I've seen flashlights been used around the net. The one I uses here I bought from dealextreme in china. The laser diode can be found on e-bay, here I made two pointers. One with a 445nm blue and one 405nm ultra violet. As the driver I intend to use can handle a wide variety of diodes you can choose the one you like. The laser diode needs to be mounted and have a lens. The easy way is to just buy a mount with lens.

Step 2: Taking apart the flashlight
The flashlight screws apart in the front and the back. In the front you will find the LED mounted. The LED is mounted on whats called the "pill" thats where the battery connects and a small controller card is located for the LED.
Once screwed out you can de-solder the LED and remove it. On the other side (where the battery touches) you need to remove the controller board. Once that has been removed it's easy to drill out the pill to give room for the laser driver.
The small controller is needed to connect the battery. Just remove all the itty bitty components somehow, I just used a small knife and carefully scraped them away. Next up you need to find out where you can find power. Just search around with a multimeter until you find a point that connects to the ring around the controller and another that connects to the "button" underneath and solder two short wires to them.
