Halloween 2021 Magic Pumpkins

A Halloween project I hoped to accomplish in 2020 was plaguing me over the weekend. It was the internal pumpkin projection mapping that I had hoped be able to build but just didn't have the time or correct construction concept.

Now, I think I'm ready.

The concept is to have the large, plastic pumpkins display the animated pumpkin faces from the inside utilizing the translucent properties of the prop. A quick test using the simple, small projectors and a mirror proved that it was possible. However, the projection ratio required the small projector be mounted about 18" away from the mirror in order to display cripsly and at the right scale.

During a trip to Home Depot over the weekend, I passed by some wall-mounted, magnifying vanity mirrors and it sparked an idea. Strangely, I installed one for my wife years ago and see it every day, yet it never sparked inspiration.

The new ideas should address two of my biggest problems. The first is to use a magnifying mirror in order to shorten the projector distance requirement. The second is to use metallic materials to construct the framing to place the pumpkins over to complete the effect. The framing can be covered by a heavy black cloth to complete the overall look.

If only I still had my Erector Set from when I was young.

Hopefully, I'll start on this project soon so that I can complete three Magic Pumpkins in time.

First Synchronized Video Produced for 2021

With the plan to use DMX synchronized video projections and lighting controllers, I have been getting busy with the setup for the 2021 Halloween display. This includes making sure the DMX hardware I have actually works and producing video content for the display. I feel that once I confirm the hardware will work, getting the hardware setup should be uneventful. The synchronized videos will require a lot more work, especially since I want to produce an hour long show (in order to not repeat the same scenes too often). I settled on four large video projectors for this season, but I know only where three of them are positioned. Figuring out where the fourth projector goes is eluding me and causing a little angst. I haven't tested the DMX controllers with the media players yet. I'm planning on testing them this weekend. This includes getting a DMX interface from the computer to the universe to work as well as sequencing software. I still have my Lynx USB-to-DMX interface but haven&

Research and Planning for Canton Chills 2020

I spent some time conducting research this weekend on video projectors, DMX lights, fog machines, and wireless transmitters, digital decorations from AtmosFX, and computer show controllers. My goal was to get a good understanding of equipment and cost and keep that understanding in the back of my mind while planning out the display. The theme of the display will be kid-friendly with hints of creepiness scattered about. I imagine something more of a Disney experience: good attention to detail with a warmer, thematic feel. I am also adjusting my mindset such that I think of it more like a show than a display. I am just not skilled enough to know whether the show is built around the display or the display is built around the show. This perspective, I need to understand. On the display side, I also started a task I was curious about for some time. That was, what is the distance to screen size projection ratio for the video projectors I have. I managed to get measurements for the mini

Plan for Halloween 2020

I think Canton Chills has been a great success over the past 5 years. Big crowds formed in front of the house and children and adults alike have been entertained and terrified. The house has earned a reputation for frightening technical excellence. Dawn and I talk about delivering a more kid-friendly experience every year. I still want it to be entertaining and amazing from a technical perspective. This translates into lots of planning. Our goal: Provide a family-friendly experience that amazes all age groups. The "family-friendly" part simply comes from using more comical animations and toning down the sound and special effects so as not to frighten more sensitive children (and parents). Walkways will be well lit, but scene lighting will still be theatrical. Scary sounds will be toned down and fog will be moved away from visitors. Video projections, sound, and DMX driven lights (both static set lights and color settable floods, including strobe) will all be synchronized. A s
