Stargate fan Kristian Tysse put the whole thing together and wrote painstakingly about the process on his website. He started out by 3D printing the pieces he needed to build a stargate, a base, a DHD (that’s a dial-home device), and a stargate address map.
The goal was to create a stargate with a real spinning piece, chevrons that lock and a wormhole effect. To achieve that last part, Tysse used an infinite mirror effect. The DHD has illuminated buttons, including the large red button in the center. The DHD is essentially a USB keyword, and Kristian created a custom PCB to connect all the buttons and lights.
When you tap the address symbols, the DHD will connect to a Raspberry Pi hidden in the base and check it with a list of valid addresses. Tysse got this from a list of addresses used in the show. If your sequence matches, the “stargate opens a wormhole”.
As you choose, the star gates rotate its coordinate symbols and the pieces lock exactly in place as seen in the show. And you will only get a wormhole if you choose the right address. To help with that, Tysse 3D printed a list of them on a replica goa’uld tablet.
Speaking of the show’s accuracy, the wormhole only stays open for 30 minutes. Once that time limit is reached, the whole lineup plays a quote from the show and closes the wormhole.
You can view the full report of the project on the Tysee website. Better yet, he offers a plan so you can 3D print, wire, and build your own. And if that sounds like something that doesn’t suit you, he plans to make another one to put up for auction.
