Introduction: Halloween Time Machine

Picture of Halloween Time Machine

Hello all! So this halloween I decided to build a simulator ride for the back yard of my haunt! This ride will have three LCD's running to simulate windows, moving dials, flickering lights, and even vibrating seats! Let's take a look at the steps required to build something like this.

Step 1:

The first step is to build a strong base for the outhouse to be on. I used 2x4's and screws to put it together and then some super heavy duty solid wheels were added to be able to move the time machine to storage after halloween.

Step 2:

The next step is to start your framing. I first put down a sheet of plywood to act as the flooring. Next you build your walls one at a time on a solid, flat surface. After all your walls are built, lift them up one at a time and screw them down to your base. Then screw the wall sections to each other. You can see in this photo I've added supports into the walls for the left and right LCD screens to be attached to.

Step 3:

Next step is to cover your frame. I used a very thin 1/4" wood painted black on the outside as the first skin of the time machine to make there be no slits of light showing in between the slats. This also helps with weatherproofing it a little better. The wood slats I used were just dog-eared fence pickets with the dog-ear cut flat. I added 2x4 supports to the inside so I could screw the fence pickets down, since they wouldn't be very sturdy being screwed to just the 1/4" thick wood.

Step 4:

Next up you should build a frame for the bench seat. I left the frame wide in the middle so I can add a door so that underneath I can have a subwoofer and powerstrips to power the ride equipment. I later skin this with MDF wood and put a back on it made of MDF as well.

Step 5:

Next up you need to build a door. Fairly simple if you're just using these type of hinges. Just make a square out of 2x4's and add a couple support pieces on the inside to hold the center LCD screen in place. Time to add a roof now as well. Put down tar paper using a staple gun and start laying your shingles onto the roof with roofing nails. Start at the bottom of the roof and work your way up in lines going left to right. Alternate the rows by cutting the first one so that the ends of the shingles don't all line up.

Step 6:

Next up is making the new wood look old. To make it look weathered I first put on a coat of Rustoleum Wood Stain in the Sunbleached color. This made the wood all a uniform light grey, which looked good, but kinda flat. To add the real weathered look, I then took some black latex paint and watered it down a whole bunch with water till it was super thin. I then brushed that all over the time machine, which allowed it to soak in randomly in the pits of the wood. Looking good!

Step 7:

Next up I made an instrument panel to go on the door above where I will mount the LCD screen. It's just a box made of wood that's deep enough for the servo motors to sit inside. The servo motors act as the dials and are just mounted to a piece of plexiglass that's been spray painted black on the backside. I then made some stickers that looked like dial readouts and stuck those to the plexi. The chrome plastic pieces I found on ebay for a couple bucks apiece. The servos are all attached to a Pololu USB Servo controller board.

Step 8:

The seats I don't really have a super good pic of, but they were just massage chair seat cushions that had a on off switch. I left the switch in the on position and cut the line on the positive power side and attached it into this board seen here. This is a relay that can be activated by being sent servo position commands. It's made by Basic Micro and is very sexy. So, in my software it just thinks a servo is hooked up. When I tell it to move the servo from the home position, it activates the relay, which in turn, activates the vibrating seats.

Step 9:

Next I made a cheapo light dimmer by attaching a servo motor to a dimmer switch. Using JB Weld, I glued a circle servo attachment head to the dial on the dimmer switch. When it dried I just plugged the servo in and held them all in place with some wood. Works great! Here's a schematic as well for how I wired up the lights so that they could just be plugged into a power strip.

Step 10:

Picture of
Next up is editing together all the footage. The footage was shot using a custom tripod which was basically a light stand with a piece of MDF as a place to put the cameras on. I marked the MDF as to where to position the three cameras so that each place we filmed the cameras were in the same positions. I then used blender to render out the dinosaur and after effects to build a 3d dungeon set. I then added green screen footage of the characters into the dungeon, placed the dinosaur into the outdoor footage, etc. Then I did the audio work in premiere.





Step 11:

Next up is to program the ride servos using the software which will control the ride. The software I used, Visual Show Automation (or VSA for short) is made by a company called Brookshire. It's a great piece of software. Each servo gets its own line on the timeline. You place your video and audio tracks and tell VSA which monitors need to display which video. You can then hook up a joystick to the computer, hit play in VSA, and move one of the servos in realtime using the joystick as the video plays. After you do this for each servo, you're done and ready to go!



Step 12:

Prepare to amaze! Now that the ride is up and running, find some trick or treaters out there to act as your test subjects and enjoy your work!

Is there a way to get a bill of materials?

What is running the software video? Is it a computer or rasberry pi?

This is so fun, silly, and inventive. We love people who put in so much effort just for a good time. As soon as we finish our broom closet teleportation device we'll pop on over and go for a ride!

Well done. Very thorough and well-designed.
