I just completed my own NES Controller Cellphone and it is the COOLEST THING EVER!!! The only thing that is missing is a cool charging dock, so I took it upon my self to make one.
Step 1: Parts
The base is a special peace that is used in some of the train kits.
I used it because it has 2 square holes in the middle where the charger can be feed through
Also as you can see from the pictures, it is 24 units long and 6 units wide and you will need enough peaces to make 3 layers.
If you have enough peaces that are the same color to make it with good for you but if your like me and just have a box of random colors you can just paint it afterward.
Step 2: Step 1
Make 3 layers just like what you see here.
Step 3: Step 2
The phone is just a tad bit too big for the dock so you will need to grind off just a little bit on the inside.
I used a grinding bit on my drill press and then smoothed out the rough parts with a razor blade knife.
You should not need to go very deep. About 1/16 to 1/8 of a inch should do.
Step 4: Step 3
The charger is going to rest on the left side.
On the bottom you need a peace 4 units long and on top of that you need one 2 units long. Then you will place 2 flat peaces on top for the phone to rest on.
On the right you make 2 layers that are 6 units long and 2 flat peaces on it.
Step 5: Step 4
You need to cut a slit in the bottom of the dock for the wire to go through
Step 6: Step 5
Now you need to glue the charger inside of the dock so that you can just place the phone on the dock and it will start charging.
It's best to use hot glue but if you don't have any Goop should work.
I had lots of trouble getting the charger in just the right spot but I found the best way was to plug the charger in to the phone and put some glue on the inside of the dock and putting the phone not all the way down but just a little higher than where the phone sits. By doing this you do not need to push the phone down hard to get it to charge.
Once the glue is dry, remove the phone and put some glue around the charger.
Step 7: Step 6
And there you have it, all you need to do is slap a fresh coat of paint on if needed and your ready to charge.
