Introduction: NES ZAPPER!!!
How to turn a NES Zapper into a real laser pistol. After seeing Fun With Lasers by Stephanie Maks, I got inspired when playing Duck Hunt so here is my little project.This isn't a difficult project as long as you know some of the basics of soldering. Please be extremely careful, this laser is dangerous. This is my first instructable so I'll try my best.
Disclaimer: CAUTION! As you know...lasers can be dangerous. Never point them at any living object!T his is not a toy, and this should not be used like a conventional laser pointer. In other words, don't use it in presentations, or to play with pets, or allow children to use it. It should only be operated by responsible persons who understand and respect the potential laser safety hazards.
Step 1: What We Need-
Step 2: Zapper Tear Down
First we need to open up the Zapper and basically gut it. When you have it open you can remove both counter balances ( one in the grip and the other in the barrel). Unscrew the three big screws on the trigger to remove the wiring harness. Next simply pull out the wiring harness but remember to desolder the black and red wires connecting the trigger to the circuitry, we'll need those for later. Remove the wires at the circuitry end.
Step 3: Improving the Trigger
The trigger already has a switch inside but to use it we need to make a simple modification to the trigger which will keep it from releasing when fully squeezed. Unscrew all the little screws and right between the big spring and trigger you will see a little plastic protrusion. With a pair of needle nose pliers simply twist it out. Now your trigger wont release when it is squeezed all the way. Screw the little screws back and lets move on to the electrical.
Step 4: Setting Up the Trigger and Safety Button
Okay, let me start out by saying that my friends aren't the brightest bulbs out there so I'm adding a safety button so it cant be fired without pushing both the trigger and the push button. I connected one end of the momentary button to the positive side of the battery and the other end to the red trigger wire. I later to switch the black trigger wire with matching red wire to stick with the whole positive thing.
Step 5: Almost There
Okay, this is the last step basically. Make sure the wires are long enough. The push button fits perfectly in the bottom hole so I just placed it there. Next the battery fits good where the counter balance was in the handle, you might need to twist off these little plastic nubs on the other half of the pistol. You'll know what I'm talking about when you're closing it all up. Attach the laser module with some tape or hot glue where the other counter balance went in the barrel. Then just run the negative wire to the battery and the positive to the trigger. I've included a picture with all the wires outside so its easy to follow them.
Step 6: Enjoy!
Put it all together and that's it people. It's really easy to do and you'll be the coolest nerd out there. I want to thank Stephanie Maks over at her website for making an in-depth tutorial on how to make these DVD-Lasers. Thanks to you all for taking a look at this. Hope you like it.
