This is my first instructible. I had just got my old nintendo from my parents house and the game wouldnt work so i tried to combine some parts that i had laying around. turned out pretty good and my cat loves it too. oh dont point the laser in anythings eyes. the diode is rated to 4.5 volts but i have 9 volts going to it so that might shorten the life a bit.

Step 1: Supplies and Tools

Supplies

Nintendo zapper (ebay $10)
Red Laser Diode (http://thelaserguy.stores.yahoo.net $11.50)
9 volt battery Snap Connector (http://www.radioshack.com 5 pack $2.69)
Red and Black Wire

Tools

Dremel
Wire cutter
Hot glue gun
Soldiering gun
Philips head screw driver

Step 2: Taking It Apart

Take the screws for the outer light grey cover and then the inner cover. Cut the lower part with your dremel so a battery can fit and be easily replaced.

Step 3: Batter and Trigger

Connect the trigger switch, laser diode, and battery clip so when you pull the trigger the battery gives power to the diode. Hot glue all the wires in place so they stay in place.

Step 4: Mounting the Laser

Mount the laser with hot glue. Make sure it is pointing straight before the glue cools down.

Step 5: A Slot to Charge the Battery

Leave enough wire so the battery can slip out to be replaced easily. I used electrical tape to better control the wires.

Step 6: Putting It Back Together

Put the dark grey cover back on. It took some test fits and more cutting to make the battery fit in and slide out easily. becareful with that screw hole i kind of cut into that and had to put hotglue so the screw will still kind of tighten.

Step 7: Almost Done

Put the light grey cover back on and it looks like a normal Nintendo zapper without the cord.

Step 8: All Done

now you can have your cat, dog, or baby chase the laser dot around for hours of fun.
<p>Awesome! Great idea and documentation!</p>
<p>couldn't you put the battery in the handle so it would be harder to see?</p>
Fun idea. these things sure drives my dog crazy...
I know people are going to hate me for this but..... in SOME cases by getting a cat, dog, or any pet to chase a lazer or light can make them kinda skitzafrennic (really don't know how to spell) and they are always looking for the lazer or light and they become really had to take care of.<br><br>Don't flame it's just I have seen it happen and it was really sad.....<br><br>REALLY sad.
&nbsp;Nice, I've got to give it a go.
i got a 200mw laser and i shined it near a mynah (a bird) and it got scared.....lol
if i can im gonna put a manly burning laser in :D
does it have to be a Nintendo gun can it be anything else liek another type of gaming gun?
It can be anything you can make a circuit in. Hell, it could even be a laser stapler if you wanted to. Just make sure there's room for a battery, wire, diode, and switch, and you're pretty much set.
laser stapler :O thats so awsome!!!! ill give it a go
cool idea. but your pictures break almost every rule of macro photography. Theres several great instructables on how to take better pictures, and this would greatly benefit from clearer photography.
i dont think anyone cares
Nope, I don't think anyone does either.
i care.
would the laser hurt your eyes?
Just about any laser can hurt your eyes. It looks like this one would.
yah,but what if the cat or dog just stared into the beam...
then you would turn it off.
good to know
If you used the space in the handle, you could add a sound FX circuit that would make cool ray gun zapping sounds when you pulled the trigger.
if that's what gets you going then have fun.
it would be cool to add flash chargers and a hercules/aries laser to it so it could be a real laser gun. and a bigger battery.
Add an 82 Ohm resistor to the circuit, that will fix any problems with blowing out your diode.
Thanks for this instructible, I'm gonna be making a blu-ray laser, and putting it in a zapper is a great idea!!!
tell me how it turns out...
i just made one of these and my cat LOVES it. She chased it around until she was tired. THANKS :D
Thats why i wanted to share it. im glad it worked out for you.
dude i heard of a real lazer that burns stuff it burns soooo much electricity probobly like 50k wats in like 5 mins
it depends on how powerful. also, this is a real laser.
can u elaborate how the wires connect? is it black wire, laser, battery, red wire, trigger ?
wow....
cool! ...hmm woulda been cooler if u used a higher output diode (mabe 45mw??) so you could burn stuff
it would drain the power fast, and it would be dangerous (legal?) could get u sued. BUT BURN BABY BURN!!!
so, if u could have a burning laser who cares how much it uses energy lol. dangerous yes, legal yes (you can actually buy way way way over the top strong burning ones), you could get sued just as anything els you could be sued for lol. and yes you could burn stuff with a powerful enof laser!
wait, you could burn things from far away and no one would ever know who did it!
ya . but come on were not talking about at the laser 'point' there being fire for something crazy you'd see in a video game, but yes it would burn stuff lol heres a example on a 100mw laser <a rel="nofollow" href="http://www.youtube.com/watch?v=l1vlNpLq-Dg">http://www.youtube.com/watch?v=l1vlNpLq-Dg</a> <br/><br/>(the more the mw, the more the burn)<br/>
ohh battery directly across laser diode without a resistor even? gotta be careful doing that, youll kill it if not careful. generally i think all reds are 4.5v the reason your 9v isnt killing the laser diode is because a 9v is made up of 6 button cell type cells all in series. these tiny cells just cant supply the current that the led is trying to draw from them at 9v so you get a beasty voltage drop. meaning, that your laser survives. but if you hooked it up to a 9v, or any voltage supply really, that has a higher current capacity then youll fry it in an instant. (e.g. a plug pack for charging your rc car or something) you should really put a resistor in there so as not to accidentally kill it. 10 ohm or so would prob do. but if the lasers arent expensive, and you dont have any resistors around... then meh. end of the day if it dies its only a red. still would be a waste though. nice job there anyway.
What the hell? Not a bad Instructable, actually very cool, but... Won't a 9v battery explode a laser diode? But still, WOW, awesome job! I look forward to trying this out if I can get the laser diode. Great job!!! +5/5 stars.
Thats even better, turn your nes zapper into a grenade
Cool! Great re-use for an otherwise outdated toy
I don't know about outdated. My NES zapper stills sees tons of use nearly every evening. Duck hunt all the way! Neat instructable though, even if it was done already.
I second that motion! Duck Hunt is a classic.
Adding to the dumb cop just shot a kid remark..... I think in some states its considered a felony to laze a cop
Hey, I did the same thing a couple of months ago, <a rel="nofollow" href="https://www.instructables.com/id/NES-ZAPPER!!!/">NES ZAPPER!!!</a>, Zappers RULE! haha<br/>
Only if you take to the public and say something threatening.
Cool! Great First Instructable!
That is enough to drive a cat crazy! Cool! I am giving you 4 stars. I will give you 5 if you add a video driving the cat crazy.
gj! now make it with a bluray diode and zap the duck!
