Revision as of 03:03, 28 November 2018

This article needs a big cleanup.

All of the "Uses" sections are extensively specific and detailed. They should instead give a more general overview of the sonic's uses, written in paragraphs instead of lists.

These problems might be so great that the article's factual accuracy has been compromised. Talk about it here or check the revision history or Manual of Style for more information.

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. Features included projecting soundwaves 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) 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 different versions of the Doctor's sonic screwdrivers exhibited different capabilities and uses, such as the interception of signals ranging from transmat beams [source needed] to conscious thought; [source needed] 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)

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 Doctor also used it to try and help River Song defeat a group of Silents although River teased him by saying it would be better if he used it to "build a cabinet". However, the Doctor implied that although it couldn't actually hurt the Silents it could weaken the power of their electricity, therefore allowing him to provide River with a certain degree of protection while she shot down their foes. (TV: Day of the Moon) It could also destroy ice creatures when it received the latest update. (TV: The Snowmen)

Although the Eighth Doctor once claimed the device could destroy a Dalek's brain if held directly against the casing when activated, (PROSE: War of the Daleks) according to the Tenth Doctor, the device could not be used to wound, maim or kill living things. (TV: Doomsday, The Doctor's Daughter) 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)

The Twelfth Doctor claimed to have abandoned sonic screwdrivers in favour of wearable technology like his sonic sunglasses. (TV: The Witch's Familiar, Under the Lake) However, after briefly returning to Gallifrey, he resumed using them, as his TARDIS fashioned a new one for him as a gift. Furthermore, after the Doctor had lost sight of who he was, Clara Oswald 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.

The First and Second Doctors' sonic screwdriver

A small, simple metal rod similar to a penlight, sonic screwdriver was used by the First (PROSE: Venusian Lullaby) and Second Doctors. (TV: Fury from the Deep) It was also used by the Eighth Doctor after being destroyed "centuries ago", with the Doctor claiming to his companion Samantha Jones that this was possible because "It's a Time Lord tool. Time doesn't work the same way for Time Lord tools." (PROSE: Alien Bodies)

However, according to one account, the First Doctor did not possess a sonic screwdriver, leaving him confused and somewhat irritated when the Twelfth Doctor utilised a future model. (TV: Twice Upon a Time) Indeed, an alternate Third Doctor did not recognise the device. (AUDIO: The Emporium At The End)

The Eighth Doctor carried a similar model near the end of his life. Cylindrical and silver, with a blue emitter diode tip, he used it in a surgical procedure to scan his patient and to seal incisions. This model could glow with an "almost white" light and emit great heat, be used to sharpen surgical instruments and be turned "on" and "off". (PROSE: Osskah)

Uses

The Third, Fourth and Fifth Doctors' sonic screwdriver

The Third Doctor's sonic. (TV: Carnival of Monsters)

The Third Doctor's most-used model of the sonic screwdriver was much larger than the one his first and second incarnation used; its elaborately detailed silver collar featured black and yellow stripes and red trim, and could be pulled down to activate the screwdriver. It had a removable burgundy emitter head which the Doctor would change with others, each performing a different function. (TV: The Sea Devils)

On one occasion he removed the head entirely and replaced it with a small, round mirror, which spun rapidly when he tapped its edge with his finger and hypnotized anyone who looked at it. Accompanied by a yellow light on the collar of his sonic screwdriver and the Doctor singing a Venusian lullaby, it hypnotized the aggressive Aggedor into calmness. (TV: The Curse of Peladon)

The Third Doctor later fitted the head of his sonic screwdriver with a cylindrical black magnet which enabled it to open bolted doors, especially when its polarity was reversed. This refit left the metal mostly unpainted, with a dark red emitter ring. The head of this model could be extended. (TV: Frontier in Space)

The Fourth Doctor with the sonic. (TV: The Sontaran Experiment)

Before this model met its demise, its head was repainted twice after the original coat wore off. (TV: The Keeper of Traken, Castrovalva) It was ultimately destroyed when a Terileptil leader forced the Fifth Doctor to drop the screwdriver inside a holding cell, then incinerated it with a laser gun — causing the Doctor to remark "I feel as though you've just killed an old friend." (TV: The Visitation) The Doctor went without a sonic screwdriver for some time after this model, with Nyssa lamenting his decision not to replace it. (TV: Snakedance) The Tenth Doctor also lightly mocked his past incarnation for going "hands-free" following this incident when their TARDISes accidentally collided. (TV: Time Crash)

This sonic operated at a frequency of 80 kilohertz. (PROSE: Light Fantastic)

The Doctor, leaving UNIT, left behind a prototype. UNIT scientists then tried to use reverse-engineering to understand its workings; this went on into the 21st century. Despite them trying to keep it quiet from the Doctor, he was well aware of the project by his seventh incarnation. (AUDIO: Persuasion)

A version of this screwdriver was kept in the Twelfth Doctor's office at St Luke's University. His companion Nardole made use of it in a war zone where the Daleks and Movellans skirmished. (TV: The Pilot)

Uses 

Used by the Sixth Doctor 

The Sixth Doctor once carried an unspecified replacement model for the sonic screwdriver, but had to leave it tied to the side of a video camera in a dungeon cell in order for it to keep the visual feed disabled. (PROSE: The Nightmare Fair) He later carried another sonic model during his adventures with Crystal, Jason, and Zog. (AUDIO: The Ultimate Adventure)

Uses

The Seventh and Eighth Doctors' sonic screwdriver

This section's awfully stubby.

As per Thread:133842, there is a sonic in the Doctor's possession by the time of his travels with Benny in the NAs. Info needs to be added from these sources, as well as numerous Big Finish audio dramas.

Chang Lee discovers the sonic screwdriver amongst the things he stole from the Seventh Doctor. (TV: Doctor Who)

The Seventh Doctor acquired a sonic screwdriver at an unspecified point of his life. Many contradictory accounts existed, including one which claimed he had acquired it at some point before meeting Bernice Summerfield, (AUDIO: Love and War) and another, which claimed he acquired it from himself on a parallel Earth where the species Homo Reptilicus had conquered the Earth and killed his third incarnation. (PROSE: Blood Heat, First Frontier) The Doctor himself claimed that he had only recently built one shortly before re-encountering Mortimus, (PROSE: No Future) and that he received it as compensation after suing the Terileptils for criminal damage. (PROSE: GodEngine) The Eighth Doctor claimed that this screwdriver was a spare model that had "rolled under the TARDIS console and remained there" until the Seventh Doctor found it. (PROSE: Frontier Worlds)

This model, identified as the "Mark 5" by the Eighth Doctor, (PROSE: Alien Bodies) looked similar to the screwdriver used up until his fifth incarnation: it was silver with a brass trim ring in the lower grip and a handle that resembled that of the previous sonic screwdrivers', now with a flat base. Its upper section was able to undergo telescopic collapse for ease of carrying, and, at its top, it held an emitter with a silver ring and a red bullet-shaped crystal at its centre. (TV: Doctor Who) Once, while suffering from amnesia, the Doctor was able to operate this sonic screwdriver on instinct. (PROSE: EarthWorld) This version remained in the Eighth Doctor's use throughout his life, up until its destruction at the hands of a Cyber-Leader on Earth. (COMIC: The Flood)

The Eighth Doctor had resumed using this model by the end of his life during the Last Great Time War. It was the second and final model the Doctor used thus far that bore an emitter-ring head. (TV: The Night of the Doctor) The Eighth Doctor's other choice of a diode-tipped model would become the standard for his later incarnations. (TV: The Day of the Doctor, Rose, The Christmas Invasion, The Eleventh Hour, Deep Breath)

The Eighth Doctor once commented that he felt undressed without his sonic screwdriver. (AUDIO: The Sontaran Ordeal)

A version of this screwdriver was kept in the Twelfth Doctor's office at St Luke's University. (TV: The Pilot)

Uses

Replacement on Ha'olam 

During his imprisonment by INC on Ha'olam, the Doctor's sonic screwdriver was confiscated. After his escape, he briefly used a replacement screwdriver resembling a slender metal rod with a crystal at its tip. (PROSE: Seeing I)

Uses

The Eighth Doctor's second screwdriver

The Eighth Doctor's second screwdriver. (COMIC: The Pictures of Josephine Day)

Later in his eighth incarnation, the Doctor carried a sonic screwdriver with a wooden handle. It had a metallic tip with six prongs that nested a clear diode at the end, which glowed blue when activated. (AUDIO: The Great War) Its handle doubled as a torch. (AUDIO: Sword of Orion) The Doctor claimed that he made this version of the sonic screwdriver to do more than open doors and blow up land mines. (AUDIO: X and the Daleks) He later made further modifications to the screwdriver. (AUDIO: Beachhead)

It was referred to as a pennywhistle by numerous World War I medics. (AUDIO: The Great War) The Doctor possessed it as early on as his travels with Charley Pollard, (AUDIO: The Light at the End) and was still using it in the early part of the Last Great Time War. (PROSE: Natural Regression) He had returned to using his original model by the end of his life. (TV: The Night of the Doctor)

Uses

The War Doctor's sonic screwdriver

The War Doctor's sonic screwdriver. (TV: The Day of the Doctor)

During his battles in the Last Great Time War, (COMIC: The Clockwise War) the War Doctor used a sonic screwdriver with a simple metallic handle and a red-light-emitting diode at the end. It appeared to be a further upgraded version of the Eighth Doctor's first sonic screwdriver, which he kept strapped in a bandoleer on his chest. It shared the same casing type as the screwdriver used by the Fourth Doctor, but had an extending diode head instead of an emitter head, and an additional piece added to the end of the handle that looked like a small red cap. In this way, much like the Doctor who used it and his TARDIS control room (which, also like the sonic, was primarily of a silver colour scheme, with red highlights), this sonic combined visual elements of both the classic and revived eras of the show, as its casing was more or less shared by all of the classic sonics, and having a light-emitting diode emitter and a kind of pommel at the end of the handle are characteristic of the revived sonics. (TV: The Day of the Doctor)

After regenerating at the end of the Last Great Time War, the Doctor kept this model with him during the early adventures of his ninth incarnation. This version was destroyed when the Doctor rigged it to explode in order to seal a rift in interstital space. (AUDIO: The Bleeding Heart)

Uses

The Ninth and Tenth Doctors' sonic screwdriver

The Ninth Doctor's sonic screwdriver. (TV: Boom Town)

After the destruction of his last model, the Ninth Doctor built himself a new sonic screwdriver. This one had a creamy light grey handle with a "cracked-porcelain" texture matching elements on his TARDIS console and rings around the roundels on the control room walls, silver metal at both the bottom of the handle and the top, and was capped off with a black pommel. Its emitter was blue and sat atop a silver metal section attached to a transparent tube containing black and red wires twisted around each other in the centre that was hidden inside the handle until extended by the slider on the side. The Doctor used this model far more frequently than his previous incarnations had done before. (TV: Rose, et al.) The Tenth Doctor also used this model, as he liked tinkering with technology to make devices he needed.

A replacement sonic used by the Tenth Doctor after overloading the former model. (TV: Human Nature)

This version was burnt out by accident after the Tenth Doctor used it to modify an X-ray output to over 5000%, however, and he replaced it with a similar one with a flatter slider, two yellow wires in the tube instead of the black and red ones, and a greyer handle, (TV: Smith and Jones) though it reverted to its cream handle during his time with Queen Elizabeth (TV: The Day of the Doctor) and appeared to have a blue handle following his regeneration. (TV: The Eleventh Hour) The model underwent several changes in shape[source needed] and colouration, some inadvertent. (COMIC: Laundro-Room of Doom) This version of the sonic screwdriver was also the first to be shown to have a direct connection to the Doctor's TARDIS (TV: Aliens of London) and could be used to override its functions. (TV: Utopia) The Tenth Doctor had this screwdriver on his person during his regeneration, but it was damaged repeatedly afterwards, leading to many malfunctions. Despite the damage, the Eleventh Doctor used it to overload technology in an attempt to alert the Atraxi to Prisoner Zero's location. This fried it into useless, charred metal, much to his growing annoyance and anger. (TV: The Eleventh Hour)

Multiple versions of these screwdrivers were kept in the Twelfth Doctor's office at St Luke's University. (TV: The Pilot)

The Eleventh and Twelfth Doctors' sonic screwdriver

The Eleventh Doctor's sonic screwdriver (TV: The Hungry Earth)

After the loss of the previous sonic screwdriver, the TARDIS gifted the Doctor with a new model. Differing radically from the last, with its extendible "claws" and green crystalline emitter resembling the inner structure of the TARDIS's new time rotor, it also had copper plating similar to the new control room. (TV: The Eleventh Hour) A psychic interface allowed its user to point it at a target and think of the function they wanted. (TV: Let's Kill Hitler, Death in Heaven) Having been mentioned to be more than sonic, (TV: Night Terrors) this screwdriver also shot beams of green energy in the shape of sonic waves. (TV: Day of the Moon, Closing Time) By at least the time of the Doctor's thirteenth regeneration, it had a voice-activation feature, which the Doctor forgot about when he needed it. (TV: Deep Breath) It had a charge that could last centuries; it once lasted 300 years before the Doctor could charge it in the TARDIS. (TV: The Time of the Doctor)

Retaining ineffectiveness against wood, it also didn't work against Peg Dolls (TV: Night Terrors) or the Wooden King and Queen. (TV: The Doctor, the Widow and the Wardrobe) The Doctor considered it embarrassing and said that "I need to invent a setting for wood." (TV: Night Terrors) In similar situations, he yelled at it in panic; "Aliens made of wood, you know this was always going to happen!", "Yes, I know it's wood. Get over it!" (TV: The Doctor, the Widow and the Wardrobe) Though aware of this flaw, he was still able to successfully bluff a Wooden Cyberman into destroying itself. (TV: The Time of the Doctor) He also once defended this weakness, saying "Oi! Don't diss the sonic!" (TV: The Hungry Earth) The Twelfth Doctor later upgraded the sonic, allowing it to blow up wooden objects. (TV: Robot of Sherwood) At some point it had an anti-freeze setting. (TV: The Snowmen) This screwdriver was also shown to have a "red setting", (TV: Cold War) similar to River's sonic screwdriver.

This model was lost and replaced by the Doctor repeatedly, having been bitten in half by a sky shark and left behind, (TV: A Christmas Carol) left with the Ganger Doctor, (TV: The Rebel Flesh) destroyed by Danny Fisher (COMIC: The Blood of Azrael) and, in one instance, simply burnt out due to overuse. In the latter instance, a replacement was given to him by Santa Claus. (COMIC: Silent Knight) One of the Twelfth Doctor's sonic screwdrivers was incinerated by the Governor when he was admitted into the Prison. Clara Oswald attempted to give him a new one disguised as a large candle in a birthday cake, but the Governor refused to give the cake to the Doctor. To circumvent this, the Doctor created a sonic spoon in the interim for the time being. (PROSE: The Blood Cell) Ultimately, he left one of his screwdrivers with Davros after abandoning him as a child. Davros had it in his possession for many years after, until Colony Sarff returned it to the Doctor. By this point, it was no longer of any real use to him, as it had become heavily damaged and inoperable, visibly weather-beaten from exposure to war and conflict, and with one of the clawed prongs broken off. (TV: The Magician's Apprentice, The Witch's Familiar)

The Doctor eventually declared that he was "over" sonic screwdrivers, saying that they "spoil the line of your jacket". He replaced the screwdriver with a pair of sonic sunglasses. (TV: The Witch's Familiar)

However, he did not keep this promise, as he used this sonic screwdriver several times afterwards. (COMIC: Clara Oswald and the School of Death, The Fourth Wall)

The Twelfth Doctor's blue version. (COMIC: Tulpa)

When the Eleventh Doctor met the Tenth Doctor in England, 1562, upon the latter realising that the former was a future incarnation of himself, they both got out their sonic screwdrivers. The Eleventh Doctor immediately showed off how much bigger his was, to which the Tenth Doctor claimed that his future incarnation was compensating, remarking that "regeneration, it's a lottery." (TV: The Day of the Doctor)

A version of this screwdriver was kept in the Twelfth Doctor's office at St Luke's University. (TV: The Pilot)

At one point during his travels with Bill Potts, the Twelfth Doctor had a version of this sonic design in the colour scheme of his second sonic screwdriver. (COMIC: Tulpa)

The Twelfth Doctor's second screwdriver

The Doctor tests out his new screwdriver. (TV: Hell Bent)

After spending a period of time using a combination of sonic sunglasses and his green-emitter sonic screwdriver, (COMIC: Clara Oswald and the School of Death) the Twelfth Doctor was gifted a new model by the TARDIS.

While one account showed him gaining it after he had found Gallifrey at the end of the universe, (TV: Hell Bent) another account depicted him using it whilst travelling with Clara Oswald. (COMIC: The Day at the Doctors)

This new model had a very mechanical and complicated-looking, TARDIS blue, metal handle with multiple emitters, once again resembling the inner structure of the time rotor itself. The emitter was once again blue in colour, and the ring of emitters could all light up in a circling motion when activated. (TV: Hell Bent) He continued to use his sonic sunglasses as well, thus giving him two choices of sonic instruments. (TV: The Husbands of River Song, Extremis)

While it usually emitted a blue light, this screwdriver could also glow red (COMIC: Robo Rampage) or green. (COMIC: Gallery, TV: For Tonight We Might Die) It was still ineffectual against wood. (TV: Empress of Mars)

The Doctor sometimes attached this screwdriver to his guitar so that he could use both at the same time. (COMIC: The Pestilent Heart)

When the Doctor was stuck in 1972, the screwdriver "ran out of juice" and the Doctor was unable to charge it because he was without his TARDIS. (COMIC: Moving In)

After regenerating into the Thirteenth Doctor, the TARDIS console room exploded due to the damage it took from the intensity of the regeneration energy. The Doctor was thrown out of the TARDIS from the explosion, causing her to free fall to the Earth's surface. (TV: Twice Upon a Time) As she fell, she lost this sonic screwdriver along with everything else in her pockets. (TV: The Woman Who Fell to Earth)

The Thirteenth Doctor's sonic screwdriver

The Thirteenth Doctor's newly created sonic. (TV: The Woman Who Fell to Earth)

Due to losing everything in her pockets following her regeneration and fall, the Thirteenth Doctor lost her previous incarnation's sonic screwdriver. As a result, the Doctor chose to build one of her own in a workshop in Sheffield. This one was far simpler in appearance than the last screwdriver with a simple steel body, and a crystal on the tip that glowed yellow while in use, taken from a Stenza transport chamber. (TV: The Woman Who Fell to Earth)

It is unique from previous sonic screwdrivers in the fact that design-wise the handle was now the unique part of the sonic, as opposed to the emitter, (TV: The Woman who Fell to Earth) which had previously either had interchangeable heads, (TV: The Sea Devils - The Visitation) an extendable emitter, (TV: Smith and Jones - The Eleventh Hour) "claws" deployed when the sonic was activated, (TV: The Eleventh Hour - Last Christmas) or a large emitter glowing in a rotating fashion. (TV: Hell Bent - Twice Upon a Time)

Comparing it to a Swiss Army knife, but without the knife, the Doctor explained that it functioned not only as a screwdriver, but as a scanner and a tin opener, and it could be used for diagnostics. (TV: The Woman Who Fell to Earth) The back of the sonic concealed a black marker tip that the Doctor could use to write down facts relavent to her current situation. (TV: Rosa, Arachnids in the UK)

It had a self-rebooting feature, allowing it to restore power if drained. (TV: The Tsuranga Conundrum) It could not work on machinery if the power cells were fluctuating. (TV: Kerblam!)

Behind the scenes

The sonic screwdriver prop

  • The sonic screwdriver was retired during the Fifth Doctor serial The Visitation, as it was felt that it had been overused. It was absent for the Sixth and Seventh Doctor's eras, except in the TV Movie, in which the Seventh Doctor used it to lock the 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.
  • During early production of series 1 (2005), the production crew decided to switch from their original prop to one based on the toy sonic screwdriver because the first prop was prone to falling apart. The production team secured moulds of the toy replica to make a more reliable prop for the next season.[source needed]
  • 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.
  • Sometimes the production team used the Character options toy to replace the actual prop. (TV: The Rings of Akhaten) [statement unclear]
  • The Third Doctor's sonic screwdriver is a modified prop from the film Thunderbirds Are Go, the prop was originally used by Alan to unscrew the wires of the Zero-X junction box. After production had finished on the film and its sequel, Thunderbird 6, Century 21 studios were closed and many props sold off. [1] [2]

Concept art

  • Early conceptual art of the modern era[which?] 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)

Sonic screwdriver toy

  • 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 customiseable 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.

Attack of the Graske

  • In NOTVALID: Attack of the Graske, the Tenth Doctor appears to break the fourth wall by noting the player at home's been watching his adventures. Later, he points the sonic screwdriver at the television screen, transferring its powers to the player's digital remote control. This, along with having the player choose multiple endings to this game, disqualifies it as a valid source on this wiki.

Other matters

  • 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.[3]
  • 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.
