Here’s a pic of the guys in costume:

Here are a few close ups of the Flux Capacitor:



And here’s the hoverboard:


Time constraints kept me from completely geeking out the hoverboard, I might go back and add more parts to the bottom--although I was able to make housings for the touch lights
Here’s a break down on the Flux Capacitor construction:
I started with a basic electrical box, which I then butchered with a Dremel to get an opening for a large window frame I printed out of PETG using a 1mm nozzle:


I superglued an acrylic sheet to the frame, added a red Dymo sticker:

The case just needed two PVC elbows & some silver spray paint:

Here are the “relays” before I painted them with metallic gold spray paint:

I balked at spending $38 for spark plug covers/wires

So I decided to make my own:

After some red paint & yellow tape they looked pretty close to the real thing.
I finished the “relays" with plastic bead storage tubes: https://www.amazon.com/Plastic-Sample-C ... rage+tubes
For the lighting, I used these cool lights: https://www.amazon.com/CYLAPEX-Decorati ... ghts&psc=1
I used three strings, each wired to an Arduino. Using a basic, and I mean basic program I was able to get the lights to flash in sequence:

My wife & I are going to try & convince our twins to dress up as Gilligan & the Skipper next year. If they agree, I’ll have to whip up a coconut radio…
