NES Cartridge Speaker

Introduction

Step 2 What to do

Step 5 Done!!!

My favorite NES hack is the NES Controller MP3 player, and this NES game cartridge speaker would go perfectly with it. This hacks gives speakers a cool retro looking case, which still has quite a lot of portability (for speakers). What I like about this mod is that the cartridge has lots of space in it, so you don't need to buy special shaped or sized speakers for it unlike some hacks where if its a tiny bit larger, it might not fit.

NES Cartridge Powered Speakers


Some of you may have seen my NES Controller MP3 player. This is a companion project for it. I sometimes like to sit around and listen to music so I made these powered speakers. And since it was to go with the NES controller I made it in a NES cartridge.

Now before you even read any further. These are not really loud. Just so you know. They are great for sitting at your desk, but you would not want to have them as music for a party or anything. Now you could make a larger more powerful amp, but I didn't. Just FYI.

 

Step 1. Getting everything you wil need....


Just get your normal tools. I.E. Dremel, glue gun, soldering iron, etc...

Then you will need the following:

One NES game of your choice. I only used Rush N Attack because it was the cheapest one I could find.
Two small speakers that will fit into an NES game. 1 Watt 8 ohm. ((0.5 watt are better.))**
Two LM386N ICs
Four 100uF caps
Two 100k resistors
Two 1k pot resistors
Two rectifier diodes
One ON/OFF switch ((Just get the smallest one you can.
6-12 votls worth of batteries. I used watch batteries ((6 volts worth)) due to the limited space. You could wire up a 9 volt and just have it on the outside of the game case. But it would look kinda weird. LOL

** I got these speakers out of an old Dell laptop I had sitting around.

Step 2. What do I do with all these bits???


O.K. Heres is the schematic I used. I found it over at Bat Amps

It is simple and effective. Plus its VERY tiny. I did not make mine as small as it could be. I really think that you could fit two into a 9 volt battery casing. LOL I might have to try that for a headphone amp.

Anyway, you just follow the schematic and you should get something like I got. ((look at second pic))

Step 3. Modding the games case...


Your gonna need to cut some holes for the sound to get out.

Also you will need to drill out the spot for the switch. and the holes for the volume controls.

Just look at the pics to get an idea of what to do. Its really easy.

((YES I KNOW MINE LOOK BAD)) I was way too tired when I did it. LOL I also found out that the little circular saw blade of a dremel, WILL in fact cut through your shirt and into your flesh. So BE CAREFUL!!! ROFL

Step 4. Putting it all together...


Not to fit it all in there.

First, glue the speakers and the amps in. Put them on separate sides.

Then glue in the batteries.

Now you just have to hook up the power wires to the switch and the Diodes. Just wire the diodes in on the ground line of each amp. If you dont, the speakers will whine like crazy.

Step 5. DONE!!!!


Test it all before you screw the case together. Make sure it works.

If it does then you are done. Enjoy.
