Digitalize Your Hi-Fi System with Raspberry Pi
Based on a Raspberry Pi, HiFiBerry HAT and touchscreen, this audio system was designed and finished to match up with existing equipment.
Today you can turn on the radio, and tune in what is still an amazing array of content over the airwaves. However, digital music, via the Internet or locally stored content, gives us the ability to hear virtually limitless music or spoken word content at the touch of a few buttons. We live in an incredible time, but setting up a Hi-Fi system to take full advantage of digital options takes a little more work than merely flipping a switch and turning a dial.
For his system, “Legufix” decided to go all out, pairing a Raspberry Pi 3B+ with what looks like a very nice Denon receiver. Of course, having a Pi with a tangle of wires next to such a receiver just wouldn’t do, so he created a two-piece 3D-printed housing for the Pi. This is beautifully finished in black to match the receiver, and includes a 7" touchscreen that sits at an angle to display song info. STLs for the enclosure are available in the project's write-up.
Inside, the Pi is surrounded by a rather large aluminum heat sink, allowing it to stay cool passively, without any sort of fan to interfere with audio entertainment. Audio signals are passed along through a HiFiBerry Digi+ HAT and optical cable for maximum fidelity, and LibreElec with Kodi was chosen as the device’s control software. It’s a well executed build, so much so that Legufix even built a second unit for his brother!
