Introduction: 9-Volt Laser-----Easy,Cool, and FUN!!!!!!!!!
Step 1: You Will Need...
1) 2 9-volt battery
2)a mini pushbutton or a small on/off switch from Radio Shack
3)a 650nm 5mW 12x30mm brass case Laser Module from http://mfgcn.com/_wsn/page2.html
4)a hot glue gun
5)a metal cutter
6)a pincer pliers
8)a solder station or gun
9) some solder
Step 2: Opening the 9-volt...
Your first step is to open up a 9-volt battery. using the metal cutter and/or the pincer pliers to open the button of the 9-volt slowly. After that, take every thing out and leave the clip,the cover and the buttom peice. if you don't kown how to open a 9-volt, click here:how to open a 9-volt battery
Step 3: The Wires...
cut a hole in the 9-volt so the switch can fit using the metal cutter or the power drill. solder the wires correctly based on the simple diagram shown. it's really easy to understand it. You MUST connect the red wire to the negative terminal of the clip and the black wire to the positive terminal of the clip. See the 2nd picture for where's the positve and negative side of the clip.
Step 4: Things Are Getting Harder..
things are getting harder and harder now.put the clip (with the wire) back to the 9-volt and the switch to the hole. use the hot glue gun to put hot glue in until it was tie, but DON'T FILL UP THE WHOLE THING!!!!!!!!!anyway, put the laser in to the opening and now fill the whole thing up. you are almost done. at this point, you might want to use sand paper to scrap the matal case and use spray paint to paint it.
Step 5: Final...
now put the 9-volt battery in it and test it out. you might want to give it a holder if you like, and have fun with laser!
!!!!!DANGER!!!!! Laser can be dangerous, never point it at any living thing's eye!!!!!!!!!!!!!!!!!!
