Wiimote B Button Led Mod
Posted 24 July 2007 - 06:16 AM
In this tutorial you will learn how to light up the B Button on your wiimote!
Disclaimer- I am in no way responsible if your wiimote becomes engulfed in flames, you solder your hand to your wiimote, or some creepy combination of what has previously been mentioned.
Solder (Rosin Core/.022dia)
3mm LED color of your choice*
*In this tutorial I used a 3mm Blue LED (3.3v/30ma). I have yet to test an LED that requires 2.1v (such as Red). Assuming that the wiimote outputs 3.3v, you'll need to use an 82ohm 1/4w resistor to properly power a 2.1v LED.
Where to get LEDs-
Where to get a Tri-wing Screwdriver-
My tri-wing screwdriver looks like this-
Before we start, I've read that some wiimotes are incapable of being modded. This is indicated by a series of numbers printed on the wiimote's PCB. Just take off the battery cover, remove the batteries and take a look. This wiimote is moddable-
Modding the B Button
Finding your wiimote:
It looks like this..
Removing the screws:
Remove the battery cover. Take out the batteries. Grab your tri-wing screwdriver and take out the 4 screws indicated in the following picture-
Disassembling the wiimote:
You may have to pry a little bit. Be cautious though.. I broke the 2 tabs in the front that keep the front of the wiimote locked together.. so mine is now loose. After taking off the top, it should like this-
The PCB comes right out.. just pull a bit. It'll now look like this-
Modifying the B Button:
Take out your B Button and take a look at it. There will be a giant "tab" thing sticking out of it. I want you to get rid of it. Do this by using a dremel or just prying it out with pliers. The end result should look like this-
Bending the LED:
Not much to say here.. except for bend it as I did in the following picture-
It'll end up looking something like this when placed in the B Button-
Soldering your wires to your LED:
Grab your 30awg wire and measure about 1-1.5in and give it a snip. Repeat twice. Strip both ends. Solder one end of one wire to one leg.. and do the same for the other leg. It should end up looking something like this-
Locating the power source:
This picture should be self-explainable-
Soldering the wires:
Go ahead and solder your wires. Make sure to do it correctly.
Placing the LED in the B Button:
Now that you got your LED and wires all soldered.. go ahead and stick the LED into the B Button. I ended up taking my soldering iron and modifying the hole. I made it wider and trimmed it down a bit. It also helped that it was somewhat molten when I put the LED in it.. keeps the LED in there.
Go ahead and put your wiimote back together. Make sure all wires are out of the way. Feel free to leave the screws out for testing purposes.. up to you. Plug your batteries in (putting the cover back on isn't necessary). Then end result should looks like this-
And that's a wrap!
Hope this tutorial helps!
