Raspberry Pi: Top 37 projects to try yourself
The best projects to try with the Raspberry Pi and Raspberry Pi Zero
The Raspberry Pi is a superb piece of hardware, capable of emulating many of the tasks you might do with a traditional computer, only taking up a fraction of the space. Yet, one of its greatest strengths is its ability to support automated tasks, especially when it comes to making your home a little smarter.
To show off what this tiny hardware is capable of, we've pulled together a list of the best projects for automating everything, from feeding your pets to building your own smart assistant, all powered by one tiny but powerful mini computer.
A warning before we continue – many of these projects are a little more involved than those you might have encountered so far, so prepare to be challenged should you choose to try them out yourself.
Build a smart home hub
Kuman 4 Relay Module
Our homes are becoming incredibly connected environments, with products such as smart energy meters, smart light bulbs, and smart door locks now being a common feature. Whether you're the sort of person that wants to transform their home into a digital haven, or even if you've only got a handful of smart devices, it's possible to connect all of that technology to a single access point – using just the Raspberry Pi.
In order to build this, you'll need a Relay Module, and incredibly powerful piece of kit that will let you connect the various devices around your home directly to your Raspberry Pi board. You'll also need to source some software to manage all of those devices – thankfully there are plenty of open source tools available – and an SD card to store it on.
For full instructions on how to put this all together, we're going to refer you to this great step by step guide. Be warned, a little technical know-how is required.
Build your own AI assistant
Google has partnered with the official Raspberry Pi magazine The MagPi to release a brand new add-on board, enabling makers to add voice control and artificial intelligence to their Raspberry Pi projects.
The board allows hobbyists to make easy use of Google's Cloud Speech API for voice recognition, as well as the Google Assistant SDK that provides the AI brain for the company's smartest devices.
Issue 57 of the MagPi comes complete with a free AI kit, including the new Voice HAT add-on module, a speaker, microphone, cables, button and even an enclosure to put it in - everything you'll need to make a homebrew version of Google Home.
Start your Sonos playlists at the push of a button
Connected speaker systems like Sonos are great, but they still require you to pull out your phone, open your music app of choice, and select a playlist. This project lets you start the playlist of your choice at the push of a button, by linking an Amazon Dash button to your Sonos system.
You can even program multiple buttons with different playlists, giving you the option of choosing your favourite, or having specific playlists for each room. Party music in the living room, for example, or easy listening in the kitchen for Sunday breakfasts. You can find the full guide on Hackster.io.
A quarter-finalist in the 2014 Hackaday Prize, this project by James Pavur is designed to automate the process of making a nice loose-leaf cuppa.
Tell the Raspberry Pi for how long and at what temperature you want your tea brewed, and the Pi will activate the connected kettle, measure the temperature, and lower the tea in with a servo motor.
Once the tea leaves have been in for the desired time, it'll lift them out again, ready to be made into a lovely cup of tea.
Power Cat Feeder
We all love our animals, but sometimes an automated pet feeder sounds like a pretty nifty thing to have around the house.
We at one time showcased the work of David Bryan, who back in 2013 found himself regularly going out of town on extended trips, without being able to source a cat-sitter. Of course, one option was to simply leave out an enormous bowl of cat food, but this wasn't exactly convenient, not to mention rather unhygienic.
Through his Power Cat Feeder project, however, he could make sure they didn't overeat before going hungry. Presumably, too, it can be used to feed any animal - including humans.
Since then there have been a bunch of iterations on this idea, some of which look rather elegant. Take for instance Sam Storino's solution to help placate starving felines at 3 am. For this project, he used a dry food dispenser, a rotation servo motor, jumper cables, a Wi-Fi dongle and a Raspberry Pi board – in this case, a Raspberry Pi 2.
For full assembly instructions, head to his step by step guide.
Pi Multi-Room Music Player
Buying a bespoke multi-room sound system can be costly - but thanks to Jezsinglespeed at Instructables, you can now do it yourself for under 100. It's a simple four-step project, which is perfect if you want to introduce children the power of the Raspberry Pi.
All you need is one wireless streamer, wireless receivers (no. depends on how many rooms) and of course your trusty Pi.
The Pi Musicbox software is used to make the magic happen and the results are just as good as any off the shelf product.
