Time Machine Costume

I decided to enter my car as an exhibit at a local Halloween themed event. It was time to build a time machine “costume” for the car. This is in no way meant to be screen accurate. Here’s my goals:

  1. 100% removable, and non-destructive. No drilling or cutting the stainless, fascias, fiberglass underbody, or the wiring harness. No removing the rear windows.
  2. Exterior only. Sorry, no time circuits. No flux capacitor.
  3. Keep the costs around $100
  4. Have fun!

Let’s get started.

Base & Vents
First, I had to remove the sunshade, or the louvers. I had been wanting to repair a crack in it, and re-paint it. Maybe this will jumpstart that project. Remove, bag, and tag the bolts:

I bought an ½ inch sheet of MDF several years ago for a subwoofer project that never happened. I couldn’t find the receipt, so the 2021 price is listed below. The base only sits on the engine cover, it is not fastened down. This is intended for display only, and not for driving.

I use a thin piece or carpet, or mat I purchased for $1 or $2 to protect my engine cover. I used some other scrap wood to start building the base of the vents.

I could have used wood or metal to make the vents, but I opted to use foam core for ease and low cost. Five sheets cost me a total of $5! With a lot of measuring, I began to create the vents:
 

I used carpet tacks to hold them together, then silicone to glue them. It didn’t work well, but the price was right:

I first used a tube of silicone that was several years old. It wouldn’t set up, and turned into an oily, gooey mess. After wiping most of it away, I used a new tube:

Finally, I tried to make them water resistant with some black undercoating. This, unfortunately, made the foam core wrinkle. Oh well:

Mr. Fusion
After some searching, I found I already had the perfect plastic containers to make the Home Energy Reactor:
  

After removing the label on the hand sanitizer, cleaning of the label residue with Goo Gone, and cutting it apart:

Hot glue it together, tape off the window area, and paint:

I found the logo online, and printed it on some clear labels:

Costs: $0!

Reactor
I found a slide carousel for $2, and a plastic container for $1. I painted them black:

I had an unused 18 inch flexible LED strip. I bought it several years ago on eBay, but I can’t find the order… maybe $4? The reactor will now glow:

I connected Mr. Fusion with two screws, and a SATA cable. The cable is a cheap hinge, since I ran out of time to find an actual hinge. With some black spray paint and some wood screws, it all came together:

Costs: Roughly $7

Wormhole Emitter
Scrap 1×4 wood, wood screws, silver spray paint, and empty spray paint cans.
 

I had some LED lights I originally purchased several years ago for my engine compartment, but they were too cheap to use. I finally found the perfect use for them. Speaker wire and electrical tape connects them together:

Side mounted electrical boxes and wires
I measured the marker lights, and found some cheap plastic boxes, slightly smaller in length.

I cut off the pegboard hanger, painted them blue, and screwed on some electrical box covers:

They are mounted to the body using the same mounting holes and screws used for the front marker lights. I have many old printer and SCSI cables I had been saving for this. I also have scrap wires, and cord ducting. Finally, to attach them to the stainless, I used cheap removable hooks with a hole drilled in them for a zip tie:

The box makes it easy to install, and add or remove components:

Miscellaneous capacitors, tanks, hoses, etc
There’s nothing special about any of these. It’s mainly leftover parts from the car that have been replaced, scrap materials from home improvement projects, and other junk.

This PVC pipe also doubles as a carrying handle:

This empty container is my janitrol tank:

Delorean fuel hoses, a Delorean CV Boot, Delorean headlights, electrical boxes, BX wire, household copper pipe, an empty food container, a 220 electrical whip and outlet, a red light that I retrofitted with an LED, a PC IDE ribbon cable, a toilet tank hose, spark plug wires, and a fire extinguisher:

Flux bands
This would be the most expensive part of the project. Since it would be displayed at night, having working flux bands was essential. I opted for blue, as they appear in the movie. Note: the actual color used in the movie was white, but it appeared blue on film. After measuring the car, I found a 65 foot strip on eBay that should be perfect:

I attached them to the stainless using adhesive hooks, with a hole drilled in them, and a zip tie. I should have used the removable kind of adhesive hooks. To make them easy to remove, I first stuck the adhesive to felt to pick up some fibers and make it less tacky:

I kept the 65 foot strand as one strand, and concealed some of it in cord duct.

On the front and rear facias, I opted for painters tape:

OUTATIME license plate
I found the image online, printed it on some photo paper, and used painters tape to stick it over my real plate at the event. Cost to me: $0.

I’ve got around 40 hours into the project, including this blog post! Several people helped me on this project, and I could not have done this without them.
It was fun to build, and the car got some great reactions at the event. Unfortunately, the car narrowly missed winning an award. Maybe I’ll enter it again in a few years.

I intend to improve upon this “time machine costume” over time. Other than coming in over-budget, I accomplished my goals.

New Alternator

My alternator has been leaking a black gooey substance, and staining my garage floor for years:

Recently, my car has had an un-diagnosed electrical gremlin, causing the car to need periodic jump starts. I also needed to replace the alternator belt, so I decided it was time to replace the alternator.

The popular alternator to retrofit into the Delorean is the GM Delco-Remy CS130, and the popular car to cross reference is a 1991-1994 Saturn. I was considering buying one of these alternators from a parts store, with a lifetime warranty. Buying an off-the-shelf CS130 usually means having to swap a serpentine pulley for the V-belt pulleys. A 1/2 inch spacer is needed behind mounting ear. Some bolts need to be changed to mount and tension it correctly. A wiring harness is also needed to plug into the alternator. A new “Saturn” CS130 was near $165, while rebuilt alternators are cheaper.

I was also interested in the “Iceberg” upgrade for the CS130, which adds more cooling fins for the casing. Check out the details here: https://alternatorparts.com/iceberg.html
I wanted to stay away from high amperage output alternators, since they sometimes fail to provide adequate amperage at idle speeds. I’ve read stories of owners having to raise idle speeds since their high-output alternators were failing to charge during city driving.

After totaling the cost of new parts-store alternator, pulley, harness, and bolts, I opted to instead buy a 120 amp alternator from DMC Midwest. Their alternator, a version of the CS130, includes a different casing which mounts easily to the Delorean’s alternator bracket without a spacer. It also includes bolts, wiring harness, the correct pully, and a new belt:

Several years ago, someone posted the parts needed for a stainless turnbuckle alternator tensioner. I added the parts to another order I was already purchasing.

The hardest part of removing the old alternator is access to bolts. Also, the AC belt needs to come off when changing the alternator & water pump belt.

I spent a few hours cleaning belt shavings off the engine:

I needed a longer M8 bolt to mount the new tensioner to the timing cover. After purchasing a stainless bolt and mounting everything, I found the tensioner is too long! I cleaned up the stock bracket, and reinstalled it:
