Huon Particles
Ancient particles from the Dark Times, created by Time Lords and later by the Torchwood Institute. They are potentially deadly, contain a great amount of energy, and can cause people to inadvertently teleport as they magnetite with other sets of Huon particles. A remnant of them exists in the heart of the TARDIS.


Biodamper
A ring intended to screen the wearer from certain kinds of detection. However, it does not work on all levels. For example, in The Runaway Bride, the Biodamper is ineffective at sheilding Donna as the Huon particles she is infected with are anchient.


Crystal ball

A ball that the Carrionites in The Shakespeare Code. It acts just as you might expect a crystal to in a fairytale, and is used mainly to spy on events. At the end of the episode, Shakespeare manages to trap the Carrionites in the ball with the power of his words.


Later on, in the episode The Unicorn and the Wasp, we briefly see the crystal ball again, when the Doctor is rummaging through a suitcase.

Dalek-enhanced Sub-Machine Guns

Although looking very similar to a normal machine gun, these weapons have been enhanced by the Daleks in the episode Evolution of the Daleks. They function in the same manner as a standard Dalek weapon, but seem to be inferior in terms of firepower.

Hypersonic Sound Wave Manipulator

In The Lazerus Experiment, Professor Lazerus uses this machine as a genetic manipulation device in order to reverse aging. Although becoming young again, the process awakens dormant genes inside Lazerus causing him to mutate into a giant scorpion-like creature. This creature is capable of extracting the life force from humans.

'Timey-wimey' detector

Created by The Doctor, this machine is a detector of temporal disturbances allowing him to track people who have been transported back in time. According to The Doctor, the 'Timey-wimey' detector 'goes ding when there's stuff' and can boil eggs at thirty paces, whether the user wants it to or not. Therefore he has therefore learned to avoid hens.

Laser Screwdriver

A weapon used by The Master in The Sound of Drums. It resembles The Doctor's sonic screwdriver yet it is larger and apparently better as The Master scoffs at why anyone would 'go sonic'. It can kill with a directed laser beam or artificially age a target using the same technology as the Hyper Sound Wave Manipulator, designed by Professor Lazarus. It is built with isomorphic controls, preventing anyone but the Master from using it.

Vortex manipulator

A vortex manipulator is a more primitive form of time-travel technology. It allows the user to travel through time by taking small 'hops' through the Time Vortex. The Manipulator can also be programmed to teleport anyone touching it from place to place.

Jack: It’s called a Vortex Manipulator. He’s not the only one who can time travel–
Doctor: Excuse me, that’s not time travel. It’s like, I’ve got a sports car, you’ve got a Space Hopper!

Paradox Machine

The devise was designed by The Master from the TARDIS. By using the sheer power of the TARDIS to hold the universe together, the paradox machine prevents the universe from collapsing under the contradiction of a logical paradox - Basically, it stops the world from collapsing when someone goes back in time to kill their ancestors. When destroyed, it reverses time up to the point immediately before it was originally activated. However those close to the device are immune to this effect as they are in the 'eye of the storm'.

Anti-Regeneration Gun
In Last of the Time Lords, Martha claims that Torchwood and U.N.I.T created a gun that could prevent a Time Lord from regenerating, and that the four chemicals needed to make it work were scattered across the world. However, this gun is revealed to be a ruse created to keep the Master from discovering Martha's actual mission.

The Doctor's hand

In The Christmas Invasion, The Doctor's right hand was severed by the Sycorax leader and apparently lost. The hand was then taken by Jack, who kept it in a transparent case filled with a preservative liquid. Despite having been severed for some months by the time it is first seen, the hand has not decayed and continues to twitch as if still alive. It is seen to glow as the sound of the TARDIS engines approach, much like the TARDIS key.

In Utopia, the hand makes a reappearance as Jack brought it with him as a 'Doctor detector.' At the end of that episode the hand is stolen by the Master, and it is later revealed that he has used it to derive the Doctor's biological code, accelerating the Doctor's aging by one hundred years.

The hand is now kept by The Doctor and attatched to the TARDIS.
