I built a LEGO dock for my Motorola Droid X, complete with USB plug and magnet for full functionality.
About this creation
I made a dock for my Droid X, with USB plug.
In the spirit of other docks made for the Droid, I decided to make a LEGO dock for my new Droid X. I started the projection with a few major goals:
No sharp edges or studs showing, so that the Droid X can't get scratched
Symmetry (at least horizontally)
Secure fitting with a solid housing
I initially sculpted a basic housing for it using scrap parts. The most important aspect in initial design was getting the correct slope for the rear. There are two distinctly different sloping areas: the top area with the camera that has a larger housing, and the rest of the phone. Both of these slope at the same rate but need to be offset to deal with their size.
I added the Android guys on the side to spruce up the model a bit, and I think they turned out great. Lime green definitely goes with the standard Android color scheme, and they were really fun to put together.
Once this was done, things got a little out of control, and the pyramid-like base was born. Following that, I decided to place treads at the bottom, because treads make every LEGO model better. The USB cable routing was done using arch bricks, with initial testing using some scrap parts I had. The final model was all designed using LDD, then parts were ordered from BrickLink.
The tread base uses standard conveyor belt links and has < 1 plate of ground clearance. The treads are more for decoration but are definitely fully functional. It's a perfect fit for flat surfaces, as it looks very stationary but is still movable.
The hardest part of construction was figuring out the length of USB cable to pull through and anchor. I had to experiment a bit but finally got the right length, and the cable is very secure. It does not push into the model when plugging in, and is in the correct spot to plug in whenever you attach the Droid X.
Another very difficult part of construction was placement of the magnet to trigger dock mode. I have made the changes in the LDD file to show them, but I was able to find a magnet small and strong enough that it fit in a 1x2 brick space and magnetized the Droid X into its dock mode. Make sure to get the polarity correct! One side will do the car navigation mode, and the other will do home dock mode.
I'm very excited about this model. It was a lot of fun planning it out and finally assembling it. I only hope that the hinge controls that I use for antennae are someday out in lime green.
Parts missing from the LDD:
5x 4x12 black brick (3 go in the lowest level of the pyramid base, 2 go in the tread base)
6x 4x6 black brick (all 6 go in the tread base, above the Technic bricks and above the 4x12 bricks)
1x 1x3 black brick (goes in the dock to cover the magnet hole)
4x black hinge control stick (for antennae)
4x Technic 5-wide axle (tread base, outer treads, I used old black ones)
2x Technic 6-wide axle (for center tread)
6x Technic 16-tooth gear (goes in the tread base)
12x Technic full bushing (tread base, I used black because black is awesome)
4x Technic half bushing (tread base, for the center tread)
