The real magic behind the Holiday projection display is the clean and effortless appearance of a highly involved and technical project. A few specialized tools, specifically the Mac based media management and playback system Millumin and the laser projector line from Optima, make our display possible.
The heart of any mapped projection display is the content. Robust control and manipulation of stock content allows you to take existing pieces of media and mold them into an exciting and engaging show. Our display utilizes Millumin, which is free to try and extremely reasonably priced, given the extensive playback control.
Short-throw laser projectors have lowered the price tag and made bright saturated colors accessible to hobbyists in the market. The Optoma Technology GT1090HDR is a great laser light engine option for expansive coverage on a short throw distance.
Synchronized sound brings the display to life, and you can listen in via your car’s radio using a simple FM transmitter from the playback machine. Most units allow you to dial in the output frequency, allowing you to adjust around populated frequencies in your area.
Projection technology continues to advance, but at the hobbyist price point the output (measured in lumens) will still require ambient light management. We deploy a combination of Philips Hue products in our outdoor fixtures, as well as a Wifi controlled dimmer for incandescent light strands.
Transmitting reliable video signal over longer distances requires a pipe more robust pipe. Blackmagic Design mini-converters take the HDMI output from the laptop to HD/SDI via BNC cable, runs of more than 250 feet from the playback machine.
Protecting the technology investment necessary to pull off the display is crucial. Ring doorbells, cameras, and Apple AirTags are a few of the ways we keep an eye on the system exposed to the elements during the Holiday season.
Fall and winter here in the Midwest require protecting the projector and electronics from rain, wind, snow, et cetera. Modified and water-sealed metal garage cabinet units, like the one above, make for a great option.
Securing the enclosure requires some creative engineering. Take a look at metal helical anchors with a robust chain and lock compliment to prevent your enclosure from wandering off without a fight.
Electronics need to breathe to prevent damage or destruction from overheating. Cold winter weather helps, but airflow is pivotal to keeping electronics cool. Electronic temperature units (~$50) can trigger fans and heaters to keep the temperature in check.
