Nintendo Zapper Laser




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


Nintendo zapper (ebay $10)
Red Laser Diode ( $11.50)
9 volt battery Snap Connector ( 5 pack $2.69)
Red and Black Wire


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.

The light grey cover hides the battery. However, this does mean that you have to take off that cover every time you change it.

Correct. The light grey cover is screwed together, which holds and hides the battery. When it is time to change the battery you would need to remove the light grey cover to do so.

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.

Don't flame it's just I have seen it happen and it was really sad.....

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.

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.
