Introduction

We absolutely LOVE the new LEGO Star Wars sets that have come out over the last couple of years. They're well designed, fun to build, and look great. What would make them even more fun is if they also moved on their own!

We took an off the shelf LEGO X-Wing set and automated it so the wings open and close on their own. Even better, we added sound effects and lighting effects! But if that isn't enough we also added a motion sensor so that it would activate when someone walks by.

Overall this project isn't overly difficult to do, but does take awhile and requires a healthy amount of random Technic LEGO parts to built the gear box area.

  3. Start removing pieces from the bottom of the X-Wing. Keep going until you get to the internal gear box. Pull off the small back "storage area".

    • Start removing pieces from the bottom of the X-Wing.

    • Keep going until you get to the internal gear box.

    • Pull off the small back "storage area".

    • Set all those pieces aside for later.

  4. Insert a size 12 Axel through the back rear of the model. Carefully, and with some luck, get a 1/2 Brush onto the end of the axel. Lastly get the Bevel gear on.

    • Carefully, and with some luck, get a 1/2 Brush onto the end of the axel.

    • Lastly get the Bevel gear on.

    • Push the rod all the way in so that it connects with the other rod.

    • This is the most difficult part of the ENTIRE process. Remove more X-Wing parts if you need to.

  5. Rebuild the entire bottom of your X-Wing. Refer to the box and original directions. Rebuild the entire bottom of your X-Wing. Refer to the box and original directions.

    • Add plate, which should stick on the back the X-Wing.

    • Then start with a 1/2 Bush, followed by two of the full sized Bushings, then the Gear, and lastly a 1/2 bushing.

    • Use an orange LEGO prying tool to push the parts into the X-Wing. If you pull the axel out you'll have to take apart the bottom all over again.

    • Our pictures are not 100% accurate to our description above. We described the order in which our final build used, which required us changing a couple things after we had originally taken photographs.

  7. Put the Wings back on the same way you took them off. Attach the rubber bands.

    • Put the Wings back on the same way you took them off.

    • Attach the rubber bands.

  9. Use a large LEGO plate of some kind as your base. You'll need one with room for the gears on the back. We used some tall 1x2x5 bricks (2454) to make supports. You can use whatever you want provided that it gives enough clearance for the wings and Servo. We used some tall 1x2x5 bricks (2454) to make supports.

  10. We used a Gearbox for Worm Gear (6588) to translate motion from the Servo to the large gear. You'll need to build your own setup based on whatever LEGOs you have available. You'll most likely have to fiddle around with everything to get your spacing correct. Use our pictures as a guide.

  11. We added some 1x4 Technic bricks for the end of our size 12 Axel from the X-Wing to go into. Attach those to the Axel. Place the X-Wing onto the base plate so that everything lines up. This can be annoying. If everything doesn't line up, try again. Take it slow and easy.

    • Screw the Servo into a Servo Mount.

    • Press on the Horn.

    • Using a small gear, two 1/2 Bushings and some size two rods to create the horn adaptor.

    • Press a size 6 or 8 Axel and a full sized Bushing into the middle of the gear.

    • We used a couple of 1x4 Technic bricks and some 1x4 plates to space everything. You might need to use a different amount of plates.

  13. Pull the axel off the servo and push it into the worm gear in the gearbox. Press the Bushing up next to the worm gear.

    • Pull the axel off the servo and push it into the worm gear in the gearbox.

    • Press the Bushing up next to the worm gear.

    • Connect everything to the Servo.

    • Adjust your pieces to get the spacing correct.

  14. Use two 1x6 or 1x8 plates to create a small platform for the Robotics Board to sit on.

    • Use two 1x6 or 1x8 plates to create a small platform for the Robotics Board to sit on.

    • We need to do this since the board won't sit flush on the base plate. Feel free to do some fun designs of your own, just make sure Ground and Pin 11 are filled with a LEGO Stud.

  15. Use two Crazy Circuits SMT LED boards to add lights to the bottom of your X-Wing. Make sure you're using Nylon Conductive Tape as regular tape will break as the wings move. Place your boards on the bottom of each wing. Run Conductive Tape from the Positive on one board to the other board.

    • Run Conductive Tape from the Negative on one board to the other board.

    • Don't cover up the spots where the supports that go from the X-Wing to your Base go.

  16. Connect your X-Wing back to the base. Run Tape from Ground on the Robotics Board to the Ground on the LED Tape. Run Tape from Pin 11 to the Positive LED Tape.

    • Connect your X-Wing back to the base.

    • Run Tape from Ground on the Robotics Board to the Ground on the LED Tape.

    • Run Tape from Pin 11 to the Positive LED Tape.

    • Since Conductive Tape is not reliably conductive on the bottom you'll want to fold over the end that connects to the LED Tape. Then tape that down with another piece of Tape.

    • We found it helpful to attach the lines of Tape BEFORE we reattached the X-Wing. We just cut really long lines of tape and left them hanging while we set the X-Wing on the base. After that we connected everything.

  17. Plug the Servo into the D3 Pin set.

    • Plug the Servo into the D3 Pin set.

  18. The Diagram at the start of the guide is a good reference to show you how to wire up the Range Finder. Connect VCC to a 5V Pin.

    • The Diagram at the start of the guide is a good reference to show you how to wire up the Range Finder.

    • Connect VCC to a 5V Pin.

    • Connect Trig to A4.

    • Connect Echo to A5.

    • Connect GND to a GND Pin.

  19. Use the diagram again to help you out.

    • Use the diagram again to help you out.

    • Connect GND to a GND Pin.

    • Connect VCC to a 5V Pin.

    • Connect TX to 5.

    • Connect RX to 6.

    • Online documentation for this board is weird. Trust us, this is the correct wiring.

  20. We grabbed our sound clip via a YouTube Video. You can use any sound file as long as it's a .WAV or .MP3. (We can't give you a sound clip for Copyright reasons.)

    • We grabbed our sound clip via a YouTube Video. You can use any sound file as long as it's a .WAV or .MP3. (We can't give you a sound clip for Copyright reasons.)

    • You'll want to use just one sound clip for our code. Once you find one put it on a micro SD card formatted in FAT.

    • Put the Micro SD Card into the MP3 Player.

    • Make sure you take note as to how long your clip is, as it will be quite helpful when modifying the code.

    • X-Wing sounds are great as well as some classic Star Wars music.

  21. If you've never used our Robotics Board before you'll need to read the user guide and install the right software and drivers. You'll also need to grab and install the NewPing library as well.

    • If you've never used our Robotics Board before you'll need to read the user guide and install the right software and drivers.

    • You'll also need to grab and install the NewPing library as well.

    • Open up your Arduino software and copy our code into a new project window.

    • Lines 30 & 31 control how long the Servo will move when opening and closing the wings. We find that 20000 ms is about right. You can change the time by changing those values.

    • Line 91 controls how long the Servo pauses to wait for your audio clip. Our Sound Clip is about 25 seconds so we have it set to 25000 MS.

    • The code has the LEDs come on once the wings open, then turn off once they're closed.

  22. Attach some Speakers to the MP3 Player and run the code. (Powered Speakers with some Volume Control work best) The Servo will sound horrible. Thats expected.

    • Attach some Speakers to the MP3 Player and run the code. (Powered Speakers with some Volume Control work best)

    • The Servo will sound horrible. Thats expected.

    • You'll most likely have to modify your code several times to get the timing correct.

    • You'll also most likely have to go back and modify your gearbox or servo holding areas. The strain may push things apart on you, so modify where necessary.
