Make Laser Gun From a Cheep Imitation Nerf Gun

We have all had those Star Wars fantasies, being Han Solo running through the death star shooting those pesky storm troopers.  But alas!  You can't shoot storm troopers the same with a Nerf gun as you can with a LASER GUN.  And it's also hard when you have no idea how electronics work.  So I have created this Instructable for those with NO electronic knowledge on how to create a laser gun. This is more like a laser pointer though, but thats what happens when you leave out all those fun little parts.

WARNING: Don't point a laser into anyones eyes, and don't look into a laser aperture!

Step 1: Stuff You'll Need

laser
wire
momentary push button switch(make sure its easy to press)
solder
soldering gun(no precision tip needed)
hot glue
hot glue gun
9 volt battery
9 volt battery hook-up
click on, click off switch(optional, make sure its easy to press)
LED(optional)
2 AA batteries(goes with led)
2 AA battery holder(goes with the led)

Most of this stuff you can get at radio shack except for the laser and hot glue. I ordered the laser online at All Electronics for $7(plus $7 shipping.ARRRRG!!!) and the hot glue you can get at a craft store. If you don't want to solder you can use hot glue, but I don't highly recommend doing that, you have a good chance of the electric current not making it to the other wire. 

Step 2: Connect Electronics

You can follow the schematic below. Just remember, red wire is positive, and black wire is negative.  Leave enough room with the wire to be able to play with it some when you put it inside the gun.  I added an led because I felt like it needed something besides just a laser (also there was a second hole in my gun). My led was blue, which meant that it could handle 3 volts of power, but if you want a different color, you may have to use a resistor.  Make sure to solder the momentary push button switch to the laser and 9 volt battery and laser, and please, test before you solder. The click on, click off switch you can soler to the led and 3 volts of power(The flat end of the led is the negative end if you did not already know that).

Step 3: Put It All in the Gun

Screw open the Nerf gun and gut it. Save the screws that hold the shell and cocking handle together. Now use a lot of hot glue to hold everything where you want it.  like the push button switch in a place it will be pushed by the trigger and the click on, click off switch where it will be pushed by the cocking mechanism.

Step 4: Closing Your Blessed Blaster

Only advice is to make sure the bar on the cocking mechanism is put through the spring.

Step 5:

And there you have it!  A laser gun from a Nerf gun.  Now you can ether blast those storm troopers back or impress you colleges with you awesome laser pointer.
