Tech the Tech: How to Dial a Stargate

Or, “Mother, the chevrons are locking!”

Considering it’s just a big, spinning wheel, there’s actually a surprising amount of ambiguity about exactly how the Milky Way version of the Stargate dials. The basics are obvious. There’s an inner ring, which rotates alternatively clockwise and counterclockwise to indicate specific symbols on it, each of which is represented by one of nine corresponding chevrons on the main ring of the device. The chevrons are numbered one through seven, proceeding clockwise, ending with seven at the top, and skipping the bottom two chevrons.1In the subsequent television shows, we saw eight- and nine-chevron addresses. The nine-chevron address engaged each chevron in clockwise order, with the bottom-right chevron becoming chevron four and the normal chevron four being chevron six, and so on. We never saw an eight-chevron address dialed in enough detail to be sure of the order, but the implication in “The Fifth Race,” the first episode where it was done, is that the first six symbols encode under the normal chevrons, while the additional seventh symbol encodes at the bottom right chevron (briefly seen on a computer screen), with chevron eight at the top.

So the question left is, exactly what position on the main ring indicates which symbol is being encoded or locked by a given chevron?

Stargate Command Plaque

“SGC Logo Plaque” for Lightwave 2020 (FBX & OBJ Included), Released March 15, 2021 (CC0)—279 KB

As a quick little side-project, the other night I built the SGC Plaque. Joseph Mallozzi, who was a writer and producer on the TV shows, has been posting high-res behind-the-scenes photos, concept art, and documents since the shows were still on the air, and recently posted a construction diagram of the plaque, which made it pretty easy to model in only an hour or two, most of which was spent squinting at the measurements and comparing with some photos of the finished plaque to see how things changed between the drawing and the actual piece.

There was also a 3D rendered version used on the show as a screensaver and decorative element on computer displays which was colored differently, so I made both versions. I didn’t sweat getting the textures exactly right (and there were some shape differences with the digital version I didn’t bother changing), just going for the spirt instead of a perfect duplicate. The gaudy ’90s texturing is pretty rough, and now we’ve entered a glorious era where flat color in CGI actually look okay.
