This is a Raspberry Pi Media/Musicplayer case, which also can be used for general purpose (for example building a thin client).
It is designed to use it with a Raspberry Pi 3 and a IQaudio PiDAC+ (http://iqaudio.co.uk/audio/8-pi-dac-0712411999643.html ; the small plastic ring on top of the cinch connectors has to be removed to close the cover. This 5mm space would totally wasted in my optinion.).
Other soundcards can probably be installed if the dimensions and the connector positions are nearly the same.
If you want to use the same parts, here is my bill of materials, including article numbers of the German electronic parts store “Conrad Electronik”: https://www.dropbox.com/s/zka5diwjgptpeqg/BOM_Conrad_Electronic.pdf?dl=0
The USB connectors are common panel mounted USB connectors with male plugs.
In order to redirect the HDD activity to a front mounted LED, you have to add a “Device Tree Overlay” (please google what this is). This is pretty simple, if you use a RasPi 3 – Just add the following line to your “config.txt”:
Replace xxx with the pin the LED is connected to.
To use the encoder to control the volume, there is a simple piece of C code available from iqaudio.co.uk. However, it needs to be slightly modified depending on your music player distribution or audio config in general (soundcard device name).
Compile it (the wiringpi library needs to be installed!) and make it starting while boot (take a look at the PiDAC+ manual!).
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
