The world's first Nintendo DS 4 internal speaker mod?

Hey there, GameFaqs contributor einsteinecker here (I'm better known as mangatron in the anime world) So here we are, 10 months later from it's conception, (possibly) the world's first 4 Speaker Nintendo DS mod. Well, I've not the time to go through those 140,000+ search results, so for now I will lay claim to the title. It shouldn't have taken this long, but sickness, acquisition of HSDPA internet, writing FAQs for GameFaqs, and that other DS mod kept me quite busy till I eventually posted this on such a time of the year. So while I'd like to divulge on the details, I'll leave that for the full story here. On to the parts:

-A Nintendo DS Fat (grey and black first production run)
-2 Internal speakers from Palm Tungsten devices, or some DS Lite speaker parts from Dealextreme would be nice, except for the part where they are too large. Radioshack anyone?
-2 Copper wires measuring about 10 inches long in length, about half a millimeter thick
-Plastic (preferably rubber) tubing to fit the wires inside
-Triwing screwdriver (I used a flat tip optimized to fit the DS size)
-Flat tip screw driver (that's why I modified a flat tip for both triwing use and cross/horizontal screws)
-Some electric tape (personally I prefer Masking tape, with the right one it won't leave a mark in the long run)
-Super Glue. Super? Maybe there's something else called instant glue? What about Forever Glue? That might make a good name...
-Maybe a soldering gun, but I didn't use one. Simple, right?
-Rubber gloves or a static wrist-strap like for computers, that's if you work on the DS while it's on
-Hobby knives for cutting the new speaker holes.
-Speaker covers (those round black ones came from the Tungsten speakers)

Flash is used to try and show the cutouts where the new speakers are. The Palm T|X was used to lessen the flash reflection on the DS screens (darkest object I could find nearby, without it I have a ghastly picture)

Hmm, I don't know whether or not I should put instructions, I mean the pictures are plenty self explanatory, right? This isn't like deciding whether or not the voltage is correct, or replacing the wifi module, or replacing the screens. A couple of wire insertions and steady hands is all it takes... Or maybe I can put up some resources (really, I don't even know how to explain this in a DIY way, to me it's very simple, but yeah I know what's simple to me may not be simple to others, so...)

Those wires actually fit in there...

Ah heck, maybe I'll make it simple. Start by opening your DS. This site sounds like a good place to go. Start by removing the backing of the top screen, then the base of the lower screen, since we'll need the top exposed. The top of the DS, that is... ahem, I should note if you have any wifi game settings you'd might want to move it over to another DS since removing the battery for more than 15 seconds resets to factory defaults. Anyways, our first move would be to remove the mainboard down on the bottom half of the DS, and then hold the DS on it's side, mainboard facing you (like you're playing Hotel Dusk) and use your four fingers to lift the touchscreen up, in turn also lifting the mainboard from its roots.

For me, I started from the bottom working my way to the top. We'll start by cutting holes into the DS shell right where we want the speakers to go. And yes, I carved both holes while the mainboard was still in place. Simple right? Hint: start cutting on the outside. Once your foxholes have been dug, place your speakers as shown below. I secured them  with super glue.



Don't mind that Goldeneye game cart. There just wasn't any other FPS that year, that's all...

Now let's wire this place. As you can see in the pics, the rubberized tubing only went through the hinge part of the DS, my method of making this quick and simple (you know how hard it was to carve those holes?) I start by inserting the left speaker wiring through the hinge, followed by the right (take note the right wiring might need a bit longer wiring than the left speaker) Once the wiring is setup up on the bottom of the DS, place the mainboard in its spot and put the base of the DS back on. We're moving up top.

Hope the camera flash isn't too blinding...

The top screen of the DS is no laughing matter. As you can see, I severed the wire connecting the right (left) speaker to the circuit board. Of course such a thing can easily be worked around, so I'll caution you that you just might ruin your wiring. Now attach the wires to the main speakers, before I simply attached them to the main wiring itself but that didn't work in the long run. By attaching them to the main speakers themselves, opening and closing the DS won't interfere with the wiring too much. (yeah, I tried attaching them to the main wiring itself, wasn't a good result)

Note where the blue circled wires end.

So, with that done, I guess you can test it out! Except when you power on your DS for the first time, you will have to re-input all your data! Mwuahahaha!

Guess which is the 2 speaker loudness and the 4 speaker mod. Tested using a mono microphone setup though so the obvious is even less painfully obvious...

Enjoy your ear deafening 4 speaker DS mod! Next upgrade: inserting a subwoofer! Hoo-rah!


-Q: What's the purpose of this mod?
-A: Well, as with all of my mods, it starts as a proof of concept kind of thing, then if it works, I turn it into a full fledged working mod. Those battery mods I've been doing are like that. That and connecting the DS to a computer is just... I don't know, not worth it? Because what I did before was connect my DS to my desktop computer with a 4 speaker setup, which was also connected to a surround sound system with two 3 foot tall 1980's era speakers. Now that's connecting it to the computer. But then your playing a handheld with its strings attached to a desktop computer... hence this mod.
-Q: So how loud is it?
-A: Very loud. DS players who own more than one type would know the DS Fat is louder than the DS Lite (unfortunately, I don't have a DSi to test). Surround sound enabled games like those from Nintendo (Metroid Prime Hunters, Mario Kart etc) sound even better with this 4 speaker mod.
-Q: How's the battery life?
-A: Hard to say. The battery that's in there right now is the one from purchase, and that means it's the first production run DS battery from 5 years ago! With the battery operating at less than half of it's rated capacity, I only get around 2-2/12 hours of gameplay now. So no telling how much juice is being used (although I noticed even less playing time when the volume is full blast.

Sneak preview of my other awesome mod: possibly the world's first built-in joystick mod for the DS Lite,  removable as well enabling the DS to close!

You have no idea how much better FPS gaming has been with this joystick mod.

The story behind the making of the 4 Speaker Nintendo DS mod

So, on this last day of the year, I finally post this mod I started back in February, before that major stomach flu/food poisoning incident that crippled me for 3 months. Thanks to that sickness though, I realized no one lives forever, and so I said "This DS won't live forever either, so why not cut it up..."

I actually had second thoughts about this one. This wasn't the same as totally taking apart my Palm OS devices, or taking batteries from one device and moving it to another, this is my First Nintendo Ds, that grey and black first production run DS, the very same with a Metroid Demo and Thumb stylus strap. I have a sort of special feeling for first time devices, and I really hated cutting holes into this thing and removing screws.(My AfterBurned Original Indigo Gameboy Advance doesn't count, right?) But what I had going against my personal feelings, were several reasons:

-This DS is wearing out. I'm talking fading colors (the grey is turning white, an ominous sign of aging), serial bar code disappearing, battery that lasts about 1/4th of it's rated output, not to mention it's not really that bright and the colors just aren't up to the DS lite/DSi.
-It's heavy. Seriously, I'm not really up to holding up this thing for extended periods of time (the aforementioned sickness had me lose about 16 pounds and severely weakening my muscles).
-It's getting old to the point where a just-as-old game "Feel the Magic XY/XX" is having a working rate of 20% (The DS is having trouble reading the cart, despite the cartridge's contacts cleaned regularly). Cleaning the DS's Slot-1 contacts isn't having any results whatsoever.

The DS shows its age. Note the white-ish parts. With a little bit of work, I can turn it into a white DS!

So, rather than toss this nostalgic piece of history, I decided to mod it. Now, I really didn't think it was going to work, I also didn't like the part where the DS might end up in the grave before me, but I said what the heck, No turning back now. I succesfully ripped a battery from my Palm OS Tungsten E2 and put it in my HP iPAQ rz1715, I braved electric shocks to temporarily revive my Casio Exilim Camera, I heavily modified my HP iPAQ hx2415's D-pad into a gaming friendly version, I was on a roll to the point where  I ended up being known as the "Repairman" in the family.

The Casio Exilim camera in its current state.

Looks like an ordinary LG Chocolate cell phone, huh?

Until you find out I shoved my Gameboy Advance Micro's battery into it. Yes, I can make calls, take pictures, play music, etc. just like before the mod. And it charges through the phone.

So what we have here is a 4 speaker mod for the Nintendo DS. Originally I planned to add only 1 speaker (from the previously mentioned Tungsten E2), as well as using Fruit Ties for the cabling (don't ask). Later through several weeks of testing I find the Fruit Ties cable setup being too stiff, lacking flexibility to twist along with the upper screen. It was around this time that another one of my ancient devices, a Palm OS Tungsten E, died when I apparently forgot to charge it (it was kept on life support, constantly connected to a USB port for juice and itself being used for Palm application testing)

With another Tungsten speaker in hand, I sought out a dead electric water heater kettle and ripped the wiring out to give me the flexible cabling I needed. The end result: A beautiful sounding handheld gaming system using up double the battery life of the already paltry amount available.

So the big questions are, why a speaker mod? It wasn't my first choice, actually. I tried to give the screen more brightness, or higher contrast (I find the DS Fat to be a nice size for my hands, if only it weren't so heavy). My additional lamps weren't lighting up, so I ended up brightening up the top screen with a more highly reflective mirror reflector taken from the previously mentioned Casio Exilim camera. My question is, why didn't Nintendo include this in the first place? (The mirror-like piece of plastic goes directly behind the LCD screen, mysteriously not present in my DS Fat) By lengthening it to go under the backlight, it was able to brighten up the screen, so much so it's close to the DS lite at it's lowest setting!

Intermission time. Guys, I have to ask, does your wife (or girlfriend for those with significant others) do this? Maybe a kiss? Or is this only in Japan...

After brightening up the top screen, I thought of several things, like adding a joystick in place of the D-pad, putting Dreamcast-like triggers in place of the L and R buttons, I even thought of making an extending antennae for the Wifi module. But those were make or break mods, modifications of existing components that if something broke, there's no going back. So I decided on "additions", add-ons with no modification to existing electrical components, thereby lowering the failure rate. At an earlier time, when I opened my DS to optimize the L and R buttons, I made note of that ridiculous amount of space inside the DS. Really, this system is so mod friendly, I wonder why there isn't much mods for it (a quick search on google several weeks ago only gave me links to PSP mods)

Adding a thin piece of anything hard like in the above pic helps the L and R buttons.

So my research told me that that Tungsten E2 can really be chopped up (I was more than happy to rip it apart, several years ago that was $200 down the drain with Palm's half assed approach to a minor "upgrade" from it's previous PalmOS devices. I later bought a Palm T|X to forgot those years). My Joystick and Dreamcast triggers ideas led me to look at that vast amount of space on the sides of the DS, one could probably fit  that PSP analog stick in there. So that brought me to that other new thing bugging me of late: being in a hot country, with killer humidity levels, the A/C is on usually during the times I do my gaming sessions. Sure, headphones make a big difference in both quality and enjoyment, but I've been sticking those in my ears for 2 decades now and I'm on a quest to preserve my already great hearing. That, and I just don't like the cabling getting in the way of anything, which is probably why I use a bluetooth headset for my cell phone.

The Tungsten E2 in its current state.

So I ultimately decided that my mod had to be a speaker mod. Additional speakers in the unit would not only look cool, but it would enhance those games with surround sound, as well as not require me to wear headphones. Look, I got nothing against headphones, I use both earbud and over the ear types, mostly while gaming on my laptop, but those, especially the massive ones that cover your ears completely like ear muffs, aren't friendly when it comes to ambiance, or rather the important sounds of everyday life (I can easily miss a text message or even a phone call with headphones on) With an increase in sound volume from the source, I won't need to use headphones, and I won't miss a call or message. Or the doorbell when the mailman has a package. Or the overflights of airliners landing at the nearby airport...

The speaker candidates. Left to right: speaker from HP iPAQ rz1715, speaker from Casio Exilim camera, speaker from Samsung Upstage phone, and an unnamed speaker from some Gamecube candy holder.

The Gamecube in question. Note the 3 holes.

So the birth of the 3 speaker DS, eventually evolving into the better 4 speaker DS.

The 3 speaker mod in it's earliest conception.

Fun facts (or the painful truth's)

-While working on the battery switch of the Tungsten E2 - Hp iPAQ rz1715, as well as reviving the Casio Exilim camera, I got shocked several times, giving me the taste of the reality of tasers. I had two super nasty shocks out of several: One when the Casio camera mysteriously had charged the camera's flash module, letting me have a taste of a full flash discharge, and the other when trying to fit the E2 battery into the rz1715, I held the negative contact with one hand and the other hand was holding the positive. The most brain numbing I ever got came, and the battery super heated to such a high level I literally threw the battery across the room.(Don't ask why I forgot about human conductivity...) I was that close to having it blow up in my face. So when working on the DS mod, I used rubber gloves and continually discharged any static I may have had (the DS had to be on when attaching the speakers, so as to test levels and usability when opening/closing the DS)
-I thought of using an even bigger screen in place of the current one on the top. Believe it or not, the backlight flex cable is exactly the same size as the one used for Palm's Tungsten series (hence why I tried to add them before this 4 speaker idea, it actually fit and lit up). I'm not surprised though, at a time when Sony declared LCD shortages and dropping out of the Palm race because of that, to see the same tech in two completely different devices didn't surprise me (same way an old iPAQ rz1715 had the same sized battery as the Tungsten E2 that came 2-3 years later)
-The DS Fat doesn't not have rubber conductive pads. It instead has a similar standard button layout of handheld devices of its time, silver metallic discs on top of a circuit board. Had it had the rubber conductive pads of the DS Lite, this would have been nice to mod a joystick into, as well as give more spring to the ABXY's step. Or perhaps that low layout is more ideal for modding...
-You might have noticed some odd carvings in the case. At the headphone port, I had to carve a curve large enough for my stereo headphones 3.5mm plug to fit into there (and by that, I mean those large, ear covering style headphones. To be honest, I found only my iPod headphones to fit in the space allowed by Nintendo (and YOU know how small the 3.5mm plug is on the iPod headphones)
-I thought of putting LEDs inside the case (a la Lock's Quest LE DS) to light up some crevices in the DS, but alas, given my battery situation and those rash of news of exploding batteries I decided to just forget about lighting up my DS and instead stay with the 4 speaker layout.
-I had several candidates for the speakers, although it was too rare to find two of the same [sized] speakers to use. Perhaps it was fate that led me to buy that Tungsten E2, which would probably be one of the few series of devices I have bought (the DS's being one of them, as well as my GBA's.)
-Believe it or not, I thought of adding a third screen. Yeah, it would have worked too. In fact, it is possible, just not in the way you are thinking. See, my idea involved adding one of the dead Tungsten E's on top of the DS, itself being powered by the DS's battery. The Palm device being separate, it would have been ideal for FAQ writing and viewing (I myself a FAQ contributor for GameFaqs). Alas, we are faced with that battery drain issue. It's a nice concept though... I just prefer Windows Mobile over PalmOS.

Look forward to my DS Lite joystick mod.

Happy Holidays! How can the same thing happen to the same guy twice?

Hey Hey Hey it's a Happy Holiday! Yeah, it's that time of the year where family gathers and gives each other Nintendo 64 boxes, aka the N64 Kid, aka .... clothes. Really though, I know that clothes is the #1 gift to give for Christmas, but why? Especially when it's summer clothes, why give such a gift during winter time? (most countries, yeah I come from Germany)

Anyways, per my usual tradition, I watch Die Hard 2: Die Harder this time of the year. I know, odd isn't it? There's a whole lot of other Christmas movies out there and I watch Die Hard 2? Hey, it's not the only movie I watch, it's just the one that has a funny story attached to it.

You see, back in 2006 AFN Europe aired Die Hard 2 on their AFN Movies channel. Since this is a tradition of mine, I decided to watch theirs. Oh yeah, how fun that was. AFN Movies being a channel even kids can access, their version of Die Hard 2 was heavily censored LOL (curse words, complete lack of blood, and most notably, the famous Icicle in the eye stabbing. Remember that? Unedited you see the icicle in the guys eye, but not in the AFN one lol) Sure, I've seen Die Hard 2 plenty of times on broadcast in the USA, but I went into this one thinking AFN at least kept it original (PG13 isn't the only rated movies they air)

After that I had to watch the DVD. No way was I going to sully the day with an edited version of a classic. XD

So yeah, Happy Holidays and here's my recommended movies for this day of the year:

Die Hard 1
Die Hard 2
Jingle all the way
Home Alone 1
Home Alone 2
Wonderful Life
Night at the Museum

Coming up next: The first ever Nintendo DS 4 Speaker mod, made by me!
