This is a List of Miscellaneous Technology. This article describes all of the various technology in the Code Lyoko franchise which is significant enough to mention, but not significant enough to have its own article.
The Neuronal Headset was a headset made by Jeremie in "Temptation". It theoretically harnesses the power of the return trips to the past, and makes the person smarter, much like how X.A.N.A. is strengthened by them. In practice, it has the opposite effect. Most of the calculations Jeremie made under its influence were incorrect. Jeremie got the idea for it from Franz Hopper's diary. It deteriorates the person's physical and mental condition every time it is used, causing strange dreams, the wearer to pass out, and headaches; among other issues. Jeremie destroyed it after recovering from a prolonged period of unconsciousness and realizing that his calculations were wrong.
X.A.N.A.'s Brains were some brains in tanks in the Siberian Research Facility. They were in large tanks of yellow green liquid, and were hooked up to wires. It's unknown if they were created by X.A.N.A., or if they were left there by the former occupiers of the facility. They were exclusively shown in "Cold Sweat".
X.A.N.A.'s Circuit Boards
At the New Mexico Research Facility, X.A.N.A. was manufacturing circuit boards, likely to support the technologies being created at other bases. These were shown in "A Lack of Goodwill" and "Hard Luck".
Networks of Security Cameras have been shown throughout the Code Lyoko franchise. Instances have included:
The Factory's Security Camera network has been shown the most times. There is a camera in the supercomputer room, which was shown in "False Lead" and "Sabotage". A camera was shown in the scanner room in "A Lack of Goodwill". A camera was shown in the lab in "Kadic Bombshell". A camera on the factory floor, near the entrance was shown revealing intruders in "X.A.N.A. Awakens, Part 2", "The Girl of the Dreams", "Attack of the Zombies", "Vertigo", "Tidal Wave", "Replika", "Wrong Exposure", and "Fight to the Finish".
