Each are accutely British phenomena, crystallizations of the drive to achieve great results with minimal resources. They are, of course, a match made in heaven, so it’s no surprise to find that the popular Raspberry Pi has been used in several Doctor Who-themed projects.

K-9, The Shooty Dog Thing, Pi-Style

Back in 1977, influenced by Star Wars How Star Wars Has Influenced Other Movies and TV Shows How Star Wars Has Influenced Other Movies and TV Shows Read More ‘ droids C-3PO and R2-D2, Doctor Who’s producers decided to introduce a new robot companion for the Doctor in The Invisible Enemy (an episode written by Bob Baker and Dave Martin; Baker would later co-create Wallace & Gromit).

The robot, a dog punningly christened K-9, starred alongside the fourth Doctor Who, Tom Baker. It had a good run into 1981, and has since appeared in Doctor Who and even his own TV show, imaginatively called K-9.

Originally, K-9 was a radio-controlled prop. Over the years various toy versions have been released, and fans have built their own props, using bulky motors and servos, and little in the way of a brain. The Raspberry Pi, of course, changed all that.

Most notable, we think, is the supreme home-built K-9 from Richard Hopkins, which features a Raspberry Pi camera module 5 Things You Can Do with the Raspberry Pi Camera Module 5 Things You Can Do with the Raspberry Pi Camera Module One of the first expansions you should buy for the Raspberry Pi is the camera module. With a dedicated connector, the camera can be used for a variety of tasks. Let's take a look. Read More and has a monitor mounted on the side, along with a wagging tail.

If you want to build your own K-9, you’re strongly advised to check Richard’s blog, where you will find everything you need to get started.

Beware: this is not a project for the faint of heart!

Also worth a mention, however, is William Reichard’s wood-built K-9 complete with a nose-mounted thermal printer; on TV back in the 1970s, the original K-9 had a ticker tape printer which output results as needed.

Doctor Who and the Daleks

The Daleks, created in 1963 by future MacGyver writer Terry Nation, are synonymous with Doctor Who, so a Raspberry Pi/Dalek mashup was somewhat inevitable.

Alan O’Donohoe‘s Twitter-powered Dalek is a sight to behold:

Details on how to achieve this are thin on the ground, although we suspect you would need to start with a Twitter-configured Pi that is able to respond to Tweeted commands.

Of course, there’s no reason why you shouldn’t extend this functionality to build a Twitter-powered K-9…

Open Doors with a Sonic PiDriver

The Sonic Screwdriver has had a charmed life, first appearing in 1967 as a, well, screwdriver, and evolving over the years into a remote key, mine detonator, and portable computer hacking device.

Put short, it’s a magic wand, a narrative tool to save the Doctor and friends from being locked up and give him the ability to reprogram computers without sitting down at a dull keyboard-and-monitor. Would it be possible to build a real screwdriver capable of removing screws with ultrasonics?

Don’t be ridiculous.

However, it is possible to build a Sonic Screwdriver with infra-red.

Here’s the TV-B-Gone sonic, which switches your TV off and on thanks to a chip that is programmed via your Raspberry Pi.

But it doesn’t end there.

Home automation is also possible with a Sonic Screwdriver. Here, Pat Hartl has modified a commercially available IR remote control in order to interact with RF-compatible power outlets.

The results are impressive, and can be seen here:

But if you truly want to open doors with a DIY Sonic Screwdriver with the help of your Raspberry Pi, the project demoed below uses the distinctive whirring of the Doctor’s handy sonic wand to open a an electronically locked door, equipped with a microphone.

The TARDIS in Orbit

While it might not be able to travel in time, this TARDIS can certainly travel in space. Well, near-Earth orbit to be precise (let’s be honest, time travel and dimensional transcendence are a little beyond even the versatile Raspberry Pi).

You probably know that it is possible to launch Raspberry Pis into space using a weather balloon, so Dave Akerman opted for a scaled down police box for his fourth unmanned mission, to store the Pi and battery pack Pi to Go? 3 Ways of Powering a Raspberry Pi for Portable Projects Pi to Go? 3 Ways of Powering a Raspberry Pi for Portable Projects Want to get your Raspberry Pi out of the house and involved in some mobile projects? You'll need a battery of some sort – but there are several options available. Read More . The build had to be light enough to go into orbit while being sturdy enough to support an external camera.

Here’s the launch:

And here you can see the Pi live streaming its own recovery!

4 Doctor Who Projects: What Can You Add?

Could one or more Raspberry Pis be used to automate a DIY TARDIS console?

Perhaps a Siri-like module could be installed to engage in conversation with a Raspberry Pi-powered Cybercontroller?

We’re sure that while the 4 projects detailed here are great, you might just have some ideas that can outdo them. Or perhaps you’ve spotted a top Doctor Who/Raspberry Pi mashup that we missed.

Either way, use the comments to tell us more!

    I love that the biggest danger K9 faced in the titles of K9 & Company was falling off a wonky stone wall.

    "K-9 ... even [has] his own TV show, imaginatively called K-9."

    There was also a pilot called *K-9 and Company,* which would have brought Sarah Jane Smith (the late Elisabeth Sladen) back into the TARDIS (or at least into the Doctor Who universe).

      I considered mentioning it, but felt that it was perhaps just too much information ;)

      Of course I wrote before rumours of the K-9 film went public... :s
