Hello All! I’m new here and wanna show you my diy player.
I needed only two inputs,one for RPI one for TVs Spdif.
To build it I have used:
RPI 1 B+ (old and slow, but was laying around so I wanted use it to something)
Cheap usb soundcard (AXAGON ADA-17)
Old TDA8425 (audio processor to switch inputs and basic sound equalizer)
Spdif DAC (based on CS8416-CSZ chip)
Class-D amplifer (XH-M189)
Two cheap used VFD displays (CU20029-UW1J)
Custom power supplyboard
Old Tuner housing
RPI works as a main controler:
All code is based on python.
One of VFD displays is connected to RPI
Second VFD is driven by Attiny85 with FFT code to represent audio spectrum
Remote control is implemented with:
IR Sensor to receive commands form TV remote
Physical buttons on the case
MPD: via Home-assistant i can control volume and update it when volume was change via remote or case buttons
And few photos (sorry for low quality)
