Well, with this USB cable, you no longer need to carry a separate charger for your Gameboy Advance SP.
You can charge your GBA by plugging in to the USB port on your laptop/pc, or by plugging in to the USB port on a USB Charger, which is the type of charger that comes with many newer smart phones and MP3 players including iPod, Zune, Sansa, etc..
When I travel, I take my GBA for the plane. I don't like packing more stuff than I need, so I can use this cable along with the charger for my android phone.
Why haven't you upgraded to the Nintendo DS or PSP, you ask?
Because I'm old and these new systems are too darn complicated. I have a flash card for my GBA and I can put tons of game ROMs on it (games that I legally own of course), including an NES emulator, which gives me the opportunity to play all the best games from my childhood. Gameplay was at it best back in the days of 8-bit computing. The fancy new games with 10 buttons just aren't any fun.
What you will need:
- GBA charger
- USB cable (any kind will do, from an old MP3 player, camera, laptop cooler, etc.)
- Heat shrink tubing or electrical tape
I take no responsibilities if you shock/hurt/kill yourself or others, nor do I make any guarantees that this won't fry your GBA, PC, or any other device. This mod will break your GBA warranty, your PC warranty, your USB charger warranty, and may fail entirely. I make no guarantees that it will work. I have only tested it on my personal GBA for 1 hour, so it may very well burn down your house and your neighbor's house too. In fact, you should probably just stop reading now and move along to the next instructable on how to make a macaroni necklace. Forget you ever saw this. Move along, nothing to see here...
Step 1: Cut 'n Strip
You'll be using the USB end of the USB cable, and the end that plugs in to your GBA from the GBA charger, so figure out how long you want your cable to be and cut 'em both accordingly. Use a knife, scissors, wire cutters, a sharpened bone, or a melted plastic cup sharpened to an edge against a concrete floor (for those of you reading this in prison).
Then, strip back the plastic to reveal the wires on each cable.
On the GBA charger, you will find a green wire and some bare wire. The green wire is the positive, and the bare wire is the negative. Strip back some of the green wire.
Depending on the USB cable you sacrifice, you may find up to 4 wires and some sheathing and insulation. We're only interested in the black and red wires, so cut all the rest and strip back the black and red wires a bit.
Step 2: Join
Then twist together the bare wires and the black wire and use a bigger diameter tubing to go over all the wires, including the ones you previous connected. (I used 3/16" tubing and it was not quite large enough, so try 1/4"
Step 3: Charge!
Plug your finished cable into a PC or to a USB charger and start charging.
Save the GBA charger your sacrificed...you never know when you may need to use it for another project.
