The 1:1 replica of the TV & Film prop
Working with Reis Martin and Les Enfants de Mac Gyver, we built a 1:1 scale replica of the Stargate from Stargate Atlantis.
I worked on the LED infrastructure and the system working behind the scenes to allow a fully user intractable experience.
Below is a basic overview of the system in place to allow the system to function in terms of dialling the Stargate as it would have been in the original show.

THE FINAL LOOK
BEHIND THE ELECTRONICS
The challenge of making a user interactive replica is making it as 'idiot proof' as possible in order to keep the system running as the original Atlantis gate did, no matter what abuse it is put through.
DIAL HOME DEVICE (DHD)
the user interface panel
Each of the 37 DHD buttons have an LED cell behind them as well as a push to make button mechanism which all run back to a DMX controlled LED driver & arcade input controller board respectively. to allow individual control of each button and light output.
the 6 metre diameter output
The structure of the gate comes apart into nine pieces and the electronic system behind it has been designed to be disassembled as such. In each ninth of the gate there is an LED driver to power four individual glyphs, three permanently installed and one removable to allow access to the joins.
ARCADE BUTTON BOARD & RASPBERRY PI
detecting the button presses
The system for the button presses functions by running into two circuit boards normally used to build custom arcade game machines, each have the capacity for twenty buttons so were perfect for the job. These both run into a raspberry pi that is running a small python script that converts these button presses into an OSC (Open Sound Control) command individual to each button number.
handling the logic and sound
QLab is a show control system and in the case of the Stargate is used to handle the logic of the system. From here, it sends the relevant commands to EOS and plays the required sound effects for varying lengths depending on the buttons pressed.
ETC EOS Nomad
controlling the LED
All of the LED is controlled from here, the buttons are controlled by commands from QLab to raise that specific LED. The animations are run by effects that run in sequence to complete the dial.
