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.
