Linux is highly customizable and adaptable. Plus, it’s free! With all these qualities, it’s not surprising to hear that people use Linux for all sorts of tasks.
However, you might be surprised by some of the niche ways people use Linux. You may even want to take on some of these projects yourself.
1. Start the radio

Have you ever thought about what goes into the operation of a radio station? While this form of media has been around for over a century, operators these days use computers to make the magic happen. If you want to get into it, you can save money by using free software.
The Open Source Radio project has a Wiki page and a GitHub page filled with resources for people who want to create and run their own stations. There you can find examples of studio setups, see what operating systems people have installed, get help building low power FM stations, and more. GNU Radio is another community to add to your list.
2. Create your own car dashboard

Cars have long been equipped with sensors that show your speed and other important indicators. Newer vehicles often display this information digitally. They also come with other nice touches like Bluetooth, touchscreens and built-in navigation.
Many car manufacturers use Linux to power these systems. Not only that, you can use Linux to create your own. Several developers have experimented with this idea using Linux and the Qt toolkit, or you can put something together using a Raspberry Pi (shown in the video above).
Although you may think that pairing an OBD2 dongle with an Android app is a more pragmatic option.
3. Monitoring and analysis of your solar panels

The cost of solar panels is falling rapidly. While switching to the sun for energy still requires a costly initial investment, it can save you money in the long run. This is the case even in many less sunny regions.
How much energy do you get from your panels? Are you getting a solid return on your investment? The US Department of Energy provides the PVWatts website as a free way to answer these questions. But if you want to go deeper, the department has released the System Advisor Model tool as open source software for Windows, Mac, and Linux.
4. Water your yard or garden
