Picture of Back to the Future Model DeLorean Interactive Display
DSC_0016 (2).JPG
Although the Sunstar Back to the Future 1:18 DeLorean models are awesome on their own, I really wanted to hear sound bites from the movies and see some fire under the tire action every time I walked by my display case. Using the Arduino and Adarfruit Wave Shield, I can play music and quotes from the movies with the push of a button.   In addition, I installed several LED lights underneath the models and hacked an Under-Cabinet Light so that it can be controlled by my Arduino.  Not only does my setup play sound, LEDs light up the DeLorean from the corresponding clip.  Right now my system plays 13 different clips taken from all three movies.  The grand finale is a fully choreographed light show to the BTTF theme song!  Check out my videos to see it in action!

This does not necessarily have to be used for BTTF model cars.  You can use these same techniques to add lighting to any model car display case.  Also, you can add sound clips from any tv show or movie to complement your particular model on display.

You will need basic soldering skills and general knowledge of LEDs, buttons, and transistors for this project.  The wave shield and breadboard power supply kit need to be soldered.  Feel free to ask me any questions if you need more detail or clarification on something.

What you Need:
-Sunstar BTTF models!
-Imex Showcase Black Base
-Imex Showcase Clear Base
-Trumpeter 1/18 Display Case (Optional)
-Rite Lite Four Head, LED Under-Cabinet Light (Available on Amazon, but I got an awesome deal at Harbor Freight!)
-Computer Speakers
-Hot Glue
-BTTF Sound Bites
-SD Card

Arduino Related:
-Any Arduino.  I used a Diecimila, but any will do.  It might be nicer to use a Mega since it has more pins with PWM for fading the LED lights.
-Adafruit Wave Shield for Arduino Kit
-Barrel connector for Arduino
- Power Adapter

Electronics Components:
-Metal Pushbutton with Blue LED Ring – 16mm Momentary
-9 Blue 5mm LED
-14 Orange 5mm LED
-Adafruit Adjustable breadboard power supply kit
-5 2N2222 NPN Transistors
-Various Resistors

-Soldering Iron
-Wire Cutter
-Wire Stripper
-Dremel Tool
-Drill and Drill Bits
-Heat Shrink
-Electrical Tape
-Mini Screwdriver
Very cool! Those are probably the best display cases I've ever seen.

Thanks, I'm glad you like my project! It was my first time working with model car display cases.
