The small form factor of the Raspberry Pi Zero W enables a new range of projects. In fact, a lot of people use the Pi Zero in the final version of the project after prototyping on a different full-sized Pi board. And, that’s because it consumes much less power compared to the flagship Pi boards and makes it ideal to build battery powered gadgets.

After scouring Instructables, Reddit, Hackaday, other maker oriented communities and my own experience with Pi, I have compiled a list of projects built around the Raspberry Pi Zero and the Raspberry Pi Zero W. The community is extremely innovative and all these projects make impressive use of various features of this maker board.

So, in addition to the awesome list of Raspberry Pi Projects that we covered earlier, here, we will be focusing on Raspberry Pi Zero!

Top Creative Projects You Can Build With Raspberry Pi Zero

Of course, you’re free to use some Raspberry Pi Zero alternatives and try the same project ideas mentioned below.

1. Portable Game Console

This is by far my favorite project built around the Raspberry Pi Zero, hence featured at the top. Today we have emulators for most of the retro games. This project puts the Pi Zero in the classic game-boy form factor. You can play most of your favorite retro games and you can play them anywhere.

This project is also beautifully documented in YouTube video(s) and on Instructables.

2. DIY Smart Speaker Powered by Alexa

Amazon’s Alexa has always been very tinkerer friendly and makers around the world have built all kinds of Alexa based devices. This project also adds RGB programmable LED’s to make it look a little more like the echo speaker.

3. Home Network Music System

Getting a proper home music system setup is usually expensive. However, with the inexpensive Raspberry Pi Zero, you can utilize your MP3 collection to set up a home network music system.

This project uses the PiDrive, PiDrive is basically a Raspberry Pi Zero W attached to a hard disk. Unfortunately, I think it has been discontinued but you can also build it using a normal Pi Zero W in different configurations. You can play local music or even stream from different services.

4. Network Ad Blocker using Pi-Hole

This is something I personally use on a daily basis and it has completely changed my internet experience. If you’re someone who doesn’t want to see advertisements while you browse around online, an Ad blocker using Raspberry Pi would be exciting, right?

Pi-Hole on a Raspberry Pi can block all the ads on your entire network. Anyone on the network with an active Pi-Hole will have an ad-free experience. It also speeds up your internet experience since the bandwidth used by ads is freed up.
