Introduction: Nintendo DS Slot-2 Lights

How to make a source of light out of 2 white leds & your filler cartridge(the useless thing that came in your ds's gba slot).

Step 1: Gather Materials...

Picture of Gather Materials...

I've found a cheap set of wardrobe lights, cheaper than white led itself; so I've decided to use them, instead of buying some...

Step 2: Dismantling

Open up the cartridge and prepare some wires...
p.s. take a look at the polarity (2nd image).

Step 3: Soldering Time

Picture of Soldering Time

Desolder 2 leds
solder them to the wires
look at the 7th picture and make something similar
put some insulating tape between the wires in the cartridge

Step 4: Cartridge Mod

Take the bottom part of your cartridge and engrave it with something, like a dremel...
then detach the internal plastic separator part.

Step 5: Assembling

Put the pcb into the cartridge case (use some glue to fasten it);
close the case with the screw (do you remember where you put it?)
add some glue to the leds(to prevent short circuit).

Step 6: Let There Be Light!!

You've finished!

do you need a resistor in that?how will i know the voltage?

Charles Espeville (author)2009-11-09

Step 4, pic 2: "here you can see it more clearly"

Are you kidding me?

Quick question. Are you soldering the wires to both of the outermost contacts? The picture was hard to make out.

Step 3 pic 8: "here you can see it more clearly" lol
Step 2 pic 2: n° of pins (1 & 32)
you can solder the wires to the track of the circuit (use sandpaper first) or to the contact directly (but no more than 1-1,5 mm).

Ok... got mine to work. Found out that it is practically impossible to embed an LED into the front cover of the blank (the plastic is incredibly thick!) so I left that part off and only used the top half of the blank. Other than securing the circuit, it's pretty easy. I've attached pictures of my stab at it. Overall, it's a cool project. Thanks m6233555m! (or can I just call you 'm'? ;) )

wel i used a tiny flat screwdriver it worked for me

i made one just like that... i have a diffused blue led in a pink filler from one of my friends, i got my ds used, so i was mad when i foundout that piece was missing, waiting to be modded

Call me "m"... glad to be helpful.

Ok... got that. What about the voltage output? Say I wanted to use only one LED. Would I need a resistor?

XOIIO (author)Charles Espeville2009-12-29

The output voltage is 3.3 volts, I just tested it.

Charles Espeville (author)XOIIO2009-12-29

Thanks, XOIIO! I know I should be able to do that myself but for lack of tools... :P

XOIIO (author)Charles Espeville2009-12-29

Yeah, good multimeters are hard to find. Just a month or so ago though I found one that was $60 but on sale for $30, and it's great.

Uh...why? I mean, if you need a flashlight, go get one. And it would be more useful if there was a way to turn it off (but there probably is).

dude22072 (author)2010-06-12

could you use this gide to put a led in a normal GBA cart

juhanius (author)2010-02-14

i soldered  it and then start my ds and it started and WOOF and it just get black :(

qazwsx755 (author)juhanius2010-04-28

What where the ratings on the leds you used?

juhanius (author)2010-02-08

just wrecked my ds with that

zack247 (author)juhanius2010-02-09

how? if you followed the instructions there should be no reason for it to stop working

junits15 (author)2009-06-17

this would be cooler if there was a switch and the LEDs were actualy in the filler, it would make a handy flashlight.

willrandship (author)junits152010-01-09

Why use this as a flashlight? wouldn't you get more light out of the ds screens? :P

junits15 (author)willrandship2010-01-09

not really, you can get some pretty bright LEDs

m6233555m (author)junits152009-06-18

But there's a switch.... the ds's one, and you can place the led wherever you want, simply shorten the wires. :)

fishgish509 (author)2009-11-24

were did you find the wardrobe lights? at the dollar store?

m6233555m (author)fishgish5092009-11-25

You can try, I found them in a normal discount.

fishgish509 (author)m6233555m2009-11-25


fishgish509 (author)fishgish5092009-11-25

were did you find the tri winged screwdriver?

XOIIO (author)fishgish5092009-12-29

Even easier just use a small flat screwdricer (like a glasses one but bigger) and put it so it's inside 2 of the 3 wings and it turns as easily as a regular screw.

fishgish509 (author)XOIIO2009-12-30


m6233555m (author)fishgish5092009-11-25

I've used a standard flat screwdriver (1.8mm); and some patience.

fishgish509 (author)m6233555m2009-11-25

did you bend it with pliers?

m6233555m (author)fishgish5092009-11-27

No, but it may be useful to have pliers and hammer nearby...

fishgish509 (author)m6233555m2009-11-27

yea i do

jonty789 (author)2009-09-09

it sound cool but when i try to make it i couldn't put it back in the ds

Atomman (author)2009-05-15

Cool, but really no purpose...

m6233555m (author)Atomman2009-05-16

The filler cart is more useful now...(lol)

poptart432 (author)2009-04-09

kool but dumb

Miles Tails Prower (author)2008-11-02

This looks really cool, man! Sadly don't have any GBA games I'm going to destruct...

it's not a gba game its the dust cover.

gamewinners42 (author)2009-01-21

so the first pin on the left is + and the 1st on the right is -? so i just solder 2 ends to the left and 2 to the right?

junits15 (author)2008-12-23

how did you make your high voltage power supply?

m6233555m (author)junits152008-12-24

It's nothing special.. a flyback transformer driven by two 2n3055 with heatsink, but you can just search for "flyback" on Instructables.

Sandisk1duo (author)2008-09-18

too blury to see anything

m6233555m (author)Sandisk1duo2008-09-19

Photos were taken by my cell phone the evening(see binary clock).

The Nate Dawg (author)m6233555m2008-11-19

so solder on pins 1 and 32?

m6233555m (author)The Nate Dawg2008-11-20

Exactly... as shown on 2nd step 2nd pic...

The Nate Dawg (author)m6233555m2008-11-21

Now I see it. I didn't get that the first time I read this. I didn't know what the round things meant. I don't know if it was just me, but maybe other people won't get that either.

mettaurlover (author)2008-11-04

I'm going to make one of these, but with the LEDs contained in the cartridge, so that they don't stick out.

apr1694 (author)2008-10-22

I can see that you have an R4DS

m6233555m (author)apr16942008-10-23

It's for the HOMEBREWS... I also have an Ez 3 in1... quake 2 on the ds is one of the best thing you can have...

Alcreion (author)2008-09-19

nice r4 you pirate! lol jk i wont tell. Nice Instructable!

sharkstun97 (author)Alcreion2008-10-16

i thought it said iq like an iq gAME
