My wife bought me a showing of Back to the Future at a local theater with a meet and greet with Christopher Lloyd after.  Well that just means I need to make a flux capacitor to bring along! After some research from www.myfluxcapcitor.com and searching this site for help I was able to put it all together and keep it under $100.

First we need to draw up a plan.  I usually use sketch up, but paper this time.



First thing I did was start to wire up an Arduino Uno as I had never programmed one of these. I did write a few webpages back in '97 with wordpad, that was the extent of my coding abilities.




A screen accurate electrical box was $125, so mine was made from poplar wood.



Traced a round corner and hit it to the belt sander.



Bought some acrylic rods, balls and tubes off Amazon and ebay.  Cut them, sanded from 80-500 grit and polished them.  You can also polish with a dremel.





Here I masked off the outside of the blocks and painted them silver.




I picked up some terminal ends off Amazon to use and made them shorter.  I also made the cylinders from pine, coated it with glue and sanded it.  These are the "solenoids" for the Fluxing.



Bought some yellow/red spark plug wires off Amazon ($40!) and used those.  Came in a set of 8, so I have a few more.



Cut a hole for the window and used a piece of plexiglass.  The trim is from MccMastercarr and was $15 I think.



Found a vintage label maker at work to do the labels.  You can also buy this label maker at Staples or Amazon around $15. Pipes are PVC from the hardware store painted silver.



Putting in the electronics.  We have 16 LEDS with a resistor on each, DIP switches to change programs, and powered by a 9volt or wall adaptor.  I also picked up some connectors at Amazon so it can come apart.  There is a motion sensor on the bottom so it turns on when you walk by it.



Final prop all made and done:










Here is a youtube video of it:

I have my code posted here.  Feel free to use it as the main code I took from this site (http://forum.arduino.cc/index.php?topic=310977.0) Thanks to Elykem for getting me started with a basic code. I tried to past in a "code" box but it is too long.

Awesome! And even prooved by Doc Brown.  :)

Any recommendations on removing the code for the sensor?  I just want to be able to turn it on and run the program.  Mind you, I'm not a programmer by any means.  I have it all on the bread board and your code will run the lights as they are suppose to if it is hooked up to the computer, but because I do not have a sensor hooked up to it, I can't run it without the computer being connected...

Looks like this is an old post, but i though it was worth a try to contact you. Unfortunately I have very little skill in this Arduino world. I am trying to build a flux capacitor like you did with the motion control and extra lights. I belie understand the first part of your code well enough to set it on the Arduino board. However, I not completely sure how to completely wire it, any chance you have a wiring schematic that would go along with the code. I would really really appreciate any help you can offer. It is super awesome that Christopher Lloyd and he sign your flux capacitor.
