Today marks Pi Day, one day of the year to celebrate mathematics and all its beauty and applications in our world.

It often extends to the Raspberry Pi, a maker board which shares the name and is used the world over to create new and exciting projects in labs, workshops and back yards.

To do our part today we’ve compiled a list of our ten favourite projects based on the Raspberry Pi. Click on the name of the project to be taken to our story on the build (in a new tab) where you’ll also find links to guides and tutorials to replicate what you see.

World’s smallest arcade cabinet

While not an official record, you’ll be hard pressed to find a functioning arcade cabinet smaller than this, which measures in at just over six centimetres tall. The buttons look a bit cramped, but it’s worth the sacrifice.

Windows 98 wrist watch

Borrowing from retrufuturism as well as cyber punk, strapping an older, full fat OS from 1998 to your wrist is something you can do with a Raspberry Pi and some patience.

E ink name tag

Another PC strapped to your body, this time as a great ice breaker in a convention setting. We’re sure a company will pick this idea and mass produce them in the future.

Custom NES Classic Mini with NFC cartridges

The Classic Mini NES leaves a lot to be desired, which opens the door for improved maker projects such as this. While the console does have flash storage, 3D printed cartridges with NFC tags give you the satisfying, tactile feel of switching games.

Tweetbot that complains to your ISP when you have a slow connection

While tweeting to your ISP when your internet speeds drop will probably put you in contact with a chatbot, we find it endlessly satisfying to think of using this project. It may end with robots speaking to robots but, hey, if your ISP isn’t going to give you what you pay for, why not give them automated hell?

Smart mirror made out of a TV

The smart mirror trend was in full force a few months ago with some being based on tablets. This version, using a 32″ Samsung TV, is definitely the best looking.

SMS Cross stitch

An odd one for sure – a small screen you stick to your wall and send SMSes to. When it receives them it will display the messages on a colourful grid that looks a lot like a cross stitch.

PIX-E – the camera that only captures gifs

The age of disposable cameras is long gone, but it’s nice to create throwback projects like this. This camera will only capture gifs, making it the perfect novelty for Twitter. It was also recently upgraded with a flash.

Functional ‘Weasley Clock’ from Harry Potter

Who needs magic when you have a Raspberry Pi and GPS? This clock uses the coordinates from cellphones to track the whereabouts of a couple. Its face has the names of several locations both of them frequent, and the hands (with their pictures) move to indicate where they are.

Voice command fireplace

With all the gifs and pictures let’s have some sound. One maker hooked up his fireplaces, which has an electric starter, to the internet. With a voice command through Google, the fire starts up.

Clinton has been a programmer, engineering student, project manager, asset controller and even a farrier. Now he handles the maker side of htxt.africa.
