I wanted to build up a music player really portable, to listen to music while in my office as well as in my music room.
in 2018 I developed (as a job) a small (2.4") touchscreen display, so I decided to design my own GUI and to interface to Volumio’s API
The specs are:
PI3 + Kali reclocker
dual-mono PCM1794a DAC (I modded a commercial board)
Good headphone amp (TPA6120A2) with 6.3mm output Jack
ALPS volume control (on unbalanced output and headphones)
balanced/unbalanced out
Internal, very quiet multi stage power supply (independent output for RasPI, DAC, headphone amp)
Custom display, touchscreen
As small as possible
I enclose some photos of finished work. The overall dimensions are 200x200x60mm (hence the H60 in the name)
Everything fitted although I would have left apart the PI a little more…
PCM1794a has a very, very good (analog ? sound), lots of air around instruments
I play most 24/96KHz tunes with Tidal (Yes, I am a MyVolumio user), difference with 16/44.1 is devastating
in next project will use a bigger chassis and perhaps a multi-parallel DAC, like the DDDAC1794 NOS
Cheers,
Paolo
It is not a plugin actually, it’s a python daemon wich talks to Volumio on one side (SocketIO), and with my display with serial bidirectional communication.
Display has his own microprocessor with graphic libraries and LCD driver, so I can keep it powered all the time and switch ON/OFF raspberry with a touch…
This daemon is a your propriety o free code? I’m very interesting because I would like to upgrade my volumio system that works with a 20x4 text LCD by discontinued plug-in. It is poor of info and not work with Spotify connect.
