the best amazon Kindles are reliably good at their primary job: displaying e-books in a crisp, eye-pleasing format. But Kindle e-readers are actually more versatile than you might imagine.

If you just upgraded to a new Kindle and are looking for something to do with your old one, or if you’re just interested in seeing how hackable these e-readers are, we’ve got three projects for you to try.

These projects vary in terms of difficulty and the amount of time and effort you’ll have to invest, but complete instructions for all of them are available online, so you can follow the steps on your own Kindle.

Turn your Kindle into a Spotify controller

Part of the appeal of Spotify is that it can work on so many different devices and connect to so many other services. There are many ways to use Spotify, and that includes through your Kindle. All you need to do is provide your Spotify credentials and then make sure your Kindle is on the same Wi-Fi network as the other device you’re using to play your music, podcasts, or audiobooks.

This is possible through Kindlify.co. Open the site in the Kindle’s built-in web browser, and then tap Connect Spotify to log in. Once this is done, you should see details of whatever you’re currently playing on Spotify, although you’ll need to use another device to choose something from your library. There is more discussion about this trick on Reddit, which is where I found it.

It all works thanks to the magic of Spotify Connect, which you may have already known about. This feature allows you to play something on your laptop and then control playback from your phone, for example, or vice versa. You can also use the feature to manage playback through compatible smart speakers.

Please note that you are not actually storing music on your Kindle or running an official Spotify app. This trick is just a way to connect to your Spotify account and control what plays through it, from your Kindle. You can fast forward and rewind, pause and resume playback, all from the e-reader.

Turn your Kindle into a smart home display

Another way to reuse a Kindle and its E-Ink display is to turn it into a smart display that pulls all kinds of data from other services. You can use the e-reader to display a variety of information related to your devices, including weather forecasts, calendar information, and your to-do lists.

This is one of the more complicated projects featured here, and you need to do everything from setting up a custom website to cutting out a custom frame for your Kindle. Developer Matt Healy, who originally created all of this, has diligently provided instructions online.

It’s the kind of project you can try if you want to learn more about hardware hacking, coding, the inner workings of Kindles, and how various apps and services talk to each other. When you’re done, you might have some ideas about similar tricks you could try.

The information you display is entirely up to you, but must come from platforms that allow third-party connections. You can see from the scripts provided by Matt Healy that he managed to get real-time information from weather services, calendars, and even status reports for upcoming installments.

Turn your Kindle into a literary clock

Finally, you can also consider turning your Kindle into a literary clock. This trick keeps the e-book theme but repurposes the device into a screen that you can look at any time you want to know what time it is, with each minute represented by a different quote from a book that mentions that particular time.

As with the smart home display, this requires a significant amount of work in terms of coding and setting everything up, but again, there are complete instructions online, so you can do it yourself. You can create a stand or frame for the clock, but it’s not essential if you don’t care about the original look of the e-reader clock.
