The Doctor's sonic screwdriver

From Tardis Wiki, the free Doctor Who reference

The Doctor, throughout many of their lives, possessed a sonic screwdriver. They ostensibly upgraded and improved each subsequent model, improving functionality and adding additional features while the design changed. Features included projecting sound waves to lock or unlock doors, frying circuitry, hacking, disabling, and activating technology. It could also be used as a scanning device, with medical applications.

Each model used the same software. Essentially, the sonic screwdriver in use by the War Doctor was the same as that in the Eleventh Doctor's possession, some 400 years later. (TV: The Day of the Doctor)

At least one version of the screwdriver used a crystal similar to the Metebelis crystal sought after by the Eight Legs of Metebelis III, (COMIC: The Forgotten) while the Fifth Doctor attempted to collect a diothanine crystal from the planet Argentia where temporal zone met to focus sonic waveforms for a new sonic screwdriver. (AUDIO: Serpent in the Silver Mask) There were also electrical components. (COMIC: The Halls of Sacrifice)

The screwdriver had a multitude of settings and different versions of settings. The Tenth Doctor told Rose to use "setting 15B" to triangulate the source of the ghosts (TV: Army of Ghosts) and used 34-H to sink a ship. (COMIC: Second Wave) It had a setting 85 that undid security codes to unlock doors. (TV: The Lazarus Experiment) The Ninth Doctor told Rose to use setting 2428D to re-attach barbed wire. (TV: The Doctor Dances) Sarah Jane used the Theta Omega setting to melt plastic vines. (TV: The Android Invasion) The Twelfth Doctor told Clara to use setting 41 to send out random bursts of helicon energy to distract the Skovox Blitzer. (TV: The Caretaker) The Twelfth Doctor himself used setting 61 to knock out a cybernetically augmented dinosaur with a "sonic brainstorm". (COMIC: Spirits of the Jungle) However, at least one version of the screwdriver was able to use thoughts as well as settings. (TV: The Big Bang, Amy's Choice, Let's Kill Hitler, Death in Heaven) The same version could also be activated using the Doctor's voice. (TV: Deep Breath)

The different versions of the Doctor's sonic screwdrivers exhibited different capabilities and uses, such as medical diagnostics (TV: The Empty Child) and repair of organic parts; (TV: The Vampires of Venice) cutting, but also re-attaching materials such as barbed wire; (TV: The Doctor Dances) operating Earth machinery such as computers (TV: School Reunion) and even cash machines (at regular and high eject speeds); (TV: The Runaway Bride) creating a spark to light a candle (TV: The Girl in the Fireplace) or Bunsen burner; (TV: Evolution of the Daleks) opening and holding doors with acoustic locks; (TV: The Rings of Akhaten) and, on the rare occasion, driving screws without touching them. (TV: The War Games, The Ark in Space, The Doctor's Wife)

River Song told the Fourth Doctor that, though his current screwdriver was mostly just a screwdriver, he would later "go a bit crazy with the optional upgrades". (AUDIO: Someone I Once Knew)

Although it was primarily a tool, the sonic screwdriver could also be used as a defensive weapon, able to combine with other sonic devices to form a shield around a hostile target to either force them back (TV: The Day of the Doctor) or slow their advance. (TV: The Doctor Falls) The Tenth Doctor put it in a soundboard to destroy the Robot Santas by overloading their sensors. (TV: The Runaway Bride) The Eleventh Doctor used it to bounce sound waves off a knife held by Melody Pond, knocking it out of her hand. (TV: Let's Kill Hitler) The sonic screwdriver was also capable of holding off sound waves from creatures who relied on sound in order to attack such as the Vigil. (TV: The Rings of Akhaten)

The sonic screwdriver would, in rare occasions, be used as an offensive weapon, firing energy blasts. The Eleventh Doctor used it in this manner to help River Song defeat a group of Silents, defeating at least two of them. (TV: Day of the Moon) The Twelfth Doctor used the same model of screwdriver to blast a Hyperion, buying himself and others time to escape from it. (COMIC: The Hyperion Empire) It could also destroy ice creatures when it received the latest update. (TV: The Snowmen)

The Tenth Doctor claimed that the device could not be used to wound, maim or kill living things. (TV: Doomsday, The Doctor's Daughter) Despite this, the Third Doctor used the device to incapacitate Space Greyhounds by disrupting their brain functions, (COMIC: The Forgotten) the Eighth Doctor once claimed it could destroy a Dalek's brain if held directly against the casing when activated, (PROSE: War of the Daleks) and the Twelfth Doctor used setting 61 to knock out a cybernetically augmented dinosaur with a "sonic brainstorm". (COMIC: Spirits of the Jungle) It could destroy non-living objects or mechanisms or place living creatures in circumstances where they might die if the situation required. (TV: The Christmas Invasion) The War Doctor claimed that it was a scientific instrument rather than a water pistol, (TV: The Day of the Doctor) or indeed a magic wand. (PROSE: The Day of the Doctor)

Particularly during the Time War (AUDIO: The Satanic Mill, The Thousand Worlds, The Heart of the Battle, A Thing of Guile) and in their thirteenth incarnation, (COMIC: A New Beginning, TV: The Battle of Ranskoor Av Kolos) the Doctor was known on occasion to summon the TARDIS using their sonic screwdriver, though the Thirteenth Doctor noted that the TARDIS got "prickly" at being summoned too often, as she found it demeaning. (COMIC: A New Beginning)

For a time, the Twelfth Doctor abandoned sonic screwdrivers in favour of wearable technology - namely, his sonic sunglasses. (TV: The Witch's Familiar, Under the Lake) However, after briefly returning to Gallifrey and having Clara Oswald dematerialise with them still inside her TARDIS, he resumed using screwdrivers, as his TARDIS fashioned a new one for him as a gift. Furthermore, after the Doctor had lost sight of who he was, Clara left him a reminder to "be a Doctor" after leaving his company. As part of his role of being a Doctor was to use a sonic screwdriver, the Doctor accepted the TARDIS's gift (TV: Hell Bent) though he would continue to occasionally use the sunglasses as well. (TV: The Husbands of River Song)

In one parallel universe, an alternate female version of the Third Doctor used her sonic screwdriver to get a pound coin unstuck from a trolley. (AUDIO: Exile)

Behind the scenes[[edit] | [edit source]]

Running gag[[edit] | [edit source]]

Whenever a new Head writer takes over, they always destroy the sonic screwdriver.

    • Steven Moffat twice over, so the Twelfth Doctor didn't have a hand-me-down from Eleven; just like with Eleven from Ten.
    • Chibnall, so he could start Thirteen off from scratch.

Information from invalid sources[[edit] | [edit source]]

According to one account, the Doctor got her sonic screwdriver from the planet Argos. (TV: Untitled [+]Loading...["Untitled (The Lily Savage Show)"])

The sonic screwdriver prop[[edit] | [edit source]]

  • In Victor Pemberton's script for Fury from the Deep, it was simply described as the Doctor's "own version of a screwdriver". When seeing a normal screwdriver in rehearsals, production assistant Michael Briant suggested using another prop and the device having sonic waves, so Patrick Troughton took a penlight from the visual effects department. (DWM 277) However, during location filming, Troughton accidentally lost the original prop and it had to be replaced at the last minute by Peter Day[1] with the safety whistle[2] from Deborah Watling's life jacket outfit.[3]
  • In episode six of Fury from the Deep, the Second Doctor uses one of his devices together with some amplifiers to produce a "sonic laser soundwave" but it is unknown if this is the sonic screwdriver, and if so whether it was the retrieved original prop or not. The combined props are seen in a surviving alternate take of the climax battle of the episode, in which a sort of medical hammer appears to be lodged in the amplifier and manipulated by Troughton.
  • The Second Doctor's slim penlight prop from The War Games has been identified as a EverReady model no. 1980 (1968-70 version).[2]
  • The Third Doctor's sonic screwdriver is a modified prop from the Thunderbirds film Thunderbirds Are Go, where it appeared as a screwdriver of the non-sonic variety. When Century 21 Productions was closed, the prop, among others, was sold off to the BBC.[4]
  • The sonic screwdriver was retired during the Fifth Doctor serial The Visitation, as it was felt that it had not only been overused but also writers relied on it instead of their own inventiveness to get the Doctor out of tricky situations. It was absent for the Sixth and Seventh Doctor's eras, except in the TV Movie, where the Seventh Doctor used it to lock the Old Master's remains away. The Eighth Doctor recovered it at the end of the film. After appearing in many Seventh and Eighth Doctor audio adventures from Big Finish Productions, the tool was reintroduced with the Ninth Doctor and has become the show's most frequently used gadget besides the TARDIS itself.
  • The screwdriver was given a rest once more in series 9, only appearing in The Magician's Apprentice, and a new version was introduced in the last episode Hell Bent. It was replaced by sonic sunglasses for that entire season.
  • For unexplained reasons, the Tenth Doctor's sonic screwdriver had a green casing in The Infinite Quest.
  • There are two main versions of the Tenth Doctor's sonic screwdriver — one which has a slide feature with button, and one which does not slide and has a fixed button. The two prop types varied each episode.
  • The War Doctor's sonic screwdriver prop was created by modifying a Fourth Doctor's sonic screwdriver replica toy.
  • When the Doctor handles the screwdriver, the clinking noises produced (when he throws and catches it) are created by repeating the motions with a corkscrew, the handles of which bump against the casing to produce the required noise. These noises are dubbed over the footage in post-production.

Concept art[[edit] | [edit source]]

  • Early conceptual art of the first modern era sonic screwdriver features a different "tube" section. Notes refer to "glowing organic circuitry" and a movable ball-joint on the emitter to allow use around corners and in tight spaces. Instead of the "glowing circuitry," the actual prop and toy reproductions featured a black "swivel" like a simple helix. When given a personal copy of the concept art, David Tennant himself commented on the lack of the swivelling emitter. [source needed]
  • Another early piece of concept art, similar to a simple Bitmap drawing, reveals that the black "cap" at the reverse end of the sonic screwdriver was intended to be an opening set of "feet," allowing the sonic screwdriver to plug into a section of the TARDIS console. This feature was also dropped from the eventual prop model. [source needed]
  • Dan Walker redesigned the sonic screwdriver, devising how it looks when used by the Ninth and Tenth Doctors. "We hit upon the idea of spark plugs, which in themselves are very iconic," Walker stated. "Initially, we started off quite techy, with retractable elements that would interface with an unlimited number of devices." Despite his work on redesigning the device, Walker wasn't allowed to take one of the sonic screwdriver props home with him. (ImageFX magazine, October 2008, pp. 63 & 64)
Time Lord Victorious screwdriver concept art
  • For the Time Lord Victorious event, concept art was made of the Tenth Doctor screwdriver, modified with parts bearing Gallifreyan text. It would then feature in The Edge of Time videogame's Time Lord Victorious DLC as an item to receive to complete the DLC's level, and implicitly appear in the novel All Flesh Is Grass when the Tenth Doctor hastily repairs his sonic screwdriver with bits of his Time Lord regalia.

Sonic screwdriver toy[[edit] | [edit source]]

  • A toy of the Eleventh Doctor's version was seen in "Light Echoes", an edition of "The Sky at Night" broadcast on BBC4 on Wednesday 5th October 2010. The screwdriver was (jokingly) used to scan a part of the LOFAR radio telescope, then under construction in Chilbolton, Hampshire, UK.
  • The Eleventh Doctor's sonic screwdriver toy has a total of four sound effects, two of which alternate with every other button press. The third is activated by pressing twice and holding on the third button push. The fourth is activated with three presses and a hold on the fourth push. However, in some models of the toy, over-use of the hidden sound effects causes the sound functions to eventually break, leaving only the LED functional.
  • The customisable toy sonic screwdriver set featuring three screwdrivers with interchangeable parts can produce up to eight sound effects: the first two are the basic screwdriver sound, with slightly different pitches, and alternate each time the button is pressed. The other six effects are achieved in a similar manner to those of the Eleventh Doctor's sonic screwdriver toy, and are accompanied by a flashing lights instead of a constant light.
  • Since the War Doctor's sonic screwdriver prop was created by modifying a toy replica, the toy version that was subsequently produced is screen accurate.

Other matters[[edit] | [edit source]]

  • In the animated title sequence of the first series of Totally Doctor Who, the Tenth Doctor uses his sonic screwdriver to fire a blue burst of energy which blows off the hand of a Cyberman.
  • In the original script for The Eleventh Hour, the Doctor referred to his screwdriver as "Level 4000" technology.
  • Scientists at the University of Dundee invented a device which turns objects with ultrasonic waves, an invention which has been described as a real-world version of the Doctor's sonic screwdriver.[5]
  • Doctor Who: Legacy mobile game contains a premium pack called "Sonic Adventure", which is centred around finding various sonic devices used by different incarnations of the Doctor and by several other characters. The playable characters form this premium pack represented almost every model of sonic screwdriver encountered in the DWU.
