Building the Flux Capacitor

Final Assembly

Now that all the parts are made, I need to assemble them in their proper place. This picture shows the Arduino board mounted in place at the bottom of the box. Remember, the USB and power ports line up with the holes I previously cut for them. The small "perf" board in the top middle of the box is where I mounted the LED driver transistors. The smallest circuit board in the upper right is the Remote Control RF receiver board.

This photo shows the back of the mounting plate. I pressed in each of the LEDs, added a little adhesive, and the proceeded to solder my wires on, according to my schematic. You can see I added a few connectors in the circuit to allow me to disconnect and remove the mounting plate. Also note the four voltage drop resistors are soldered directly to the LEDs on the upper right side of the "Y".

Here I've placed the Vacuum Solenoids and Spark Plug wires on the front of the mounting plate. In hind sight I should have waited to attach the metal mounting feet that are attached to the sides of the solenoid bases. I made them all the same and apparently that is not the case in the original. I'll correct this on my next one. Also, the 4 holes in an arc will be drilled smaller in the next one.

Here's a wider shot of the finished Flux Capacitor with the door open. I am very pleased with the outcome. With a few tweaks, I think I accomplished my goal of a creating a decent replica true to the original. And I had a great time as well.

Show Time!

The Flux Capacitor defaults to a standard fluxing mode at a constant rate until one of the 5 buttons on the remote is pressed. Each mode plays for 10-15 seconds and then returns to the standard fluxing mode.Flux Capacitor Remote Control

The 5 different modes available are:

1- Ping-Pong Mode: A single light travels back and forth in each flux tube. When the light hits the outer most position, the 4 internal lights also illuminate.

2- Shuffle Mode: Two lights in each flux tube travel back and forth. I turn the 4 internal lights on when the tube lights are closest to the middle.

3- Inverse Ping-Pong: A single unlit light travels back and forth in each flux tube. This mode is tough to see in the video because of the brightness with all the lights on.

4- Disco Mode: I illuminate alternating lights in each tube. So lights 1 & 3 light, then 2 & 4 light. The 4 internal lights also alternate on and off.

5- 88 MPH Mode: The lights speed up until you hit 88 MPH and then they all flash, including the 4 extra internal lights. This is when Time Travel occurs!

I play each mode in the video below. I start with the 88 MPH Mode (#5) and then play modes #1-4 in order. You can see it return to the standard fluxing mode in between.

Flux Cap Operating Instructions

One of the fun parts of making a prop from someone is creating a unique instruction manual. I've done this in the past for my Twilight Zone Mystic Seer Kit. Since my first Flux Capacitor was a gift for my nephew, I wanted him to have some instructions when he opened it on Christmas. I've always loved the old Aurora Model kits and their assembly instructions has such a unique style to them. So, here are my Flux Capacitor Operating Instruction in the style of the old Aurora models. Click on the cover page below for the complete (PDF) manual.

..and a Flux Capacitor in a pear tree!

The two months before Christmas were very busy. I'd been wanting to finish my first Flux Capacitor to give as a Xmas present for my nephew Ben.ben with flux capacitor xm I can happily say that it was finished in time and was a big hit on Christmas. He was very surprised when he opened the packaged and could not believe what was inside.

I took many pictures over the last several weeks of construction and I will be updating all of the sections with the final details. There are a few tweaks I will be making on my next one (for me) but I could not be more pleased with how it turned out. Keep checking back. If you have any specific questions, please let me know.
