Open hardware for musicians and music lovers: Headphone, amps, and more
======
From 3D-printed instruments to devices that pull sound out of the air,
there are plenty of ways to create music with open hardware projects.
![][1]

The world is full of great [open source music players][2], but why stop at using open source just to _play_ music? You can also use open source hardware to make music. All of the instruments described in this article are [certified by the Open Source Hardware Association][3] (OSHWA). That means you are free to build upon them, remix them, or do anything else with them.

### Open source instruments

Instruments are always a good place to start when you want to make music. If your instrument choices lean towards the more traditional, the [F-F-Fiddle][4] may be the one for you.

![F-f-fiddle][5]

The F-F-Fiddle is a full-sized electric violin that you can make with a standard desktop 3D printer ([fused filament fabrication][6]—get it?). If you need to see it to believe it, here is a video of the F-F-Fiddle in action:

Mastered the fiddle and interested in something a bit more exotic? How about the [Open Theremin][7]?

![Open Theremin][8]

Like all theremins, Open Theremin lets you play music without touching the instrument. It is, of course, especially good at making [creepy space sounds][9] for your next sci-fi video or space-themed party.

The [Waft][10] operates similarly by allowing you to control sounds remotely. It uses [Lidar][11] to measure the distance of your hand from the sensor. Check it out:

Is the Waft a theremin? I'm not sure—theremin pedants should weigh in below in the comments.

If theremins are too well-known for you, [SIGNUM][12] may be just what you are looking for. In the words of its developers, SIGNUM "uncovers the encrypted codes of information and the language of man/machine communication" by turning invisible wireless communications into audible signals.

Here is in action:

### Inputs

Regardless of what instrument you use, you will need to plug it into something. If you want that something to be a Raspberry Pi, try the [AudioSense-Pi][14], which allows you to connect multiple inputs and outputs to your Pi at once.

### Synths

What about synthesizers? SparkFun's [SparkPunk Sound Kit][16] is a simple synth that gives you lots of room to play.

### Headphones

Making all this music is great, but you also need to think about how you will listen to it. Fortunately, [EQ-1 headphones][18] are open source and 3D-printable.

Are you making music with open source hardware? Let us know in the comments!
