Hi,
this is my first project a stereo receiver based on volumio with kodi. I needed all in one device with small dimensions. I decided make it own.
Here list of features:
- playing music via volumio
- playing movies via kodi
- playing sound from TV and XBOX via optic
- controling via web browser (standard volumio approach)
- controling via IR remote controll
- controling volume and play/pause via knob with button on receiver body
- indication on/off amplifier state via notification diode
- displaing time a date on LED matrix display, it hides under thin plywood
Hardware components:
- Main board - raspberry pi 3 B with three aluminium heatsinks (needed for KODI), plastic standoff spacer against ground loop
- DAC - AUDIOPHONICS DAC I-Sabre ES9038Q2M
- Amplifier - TPA3251 from 3e-audio, plastic standoff spacer against ground loop
- Power 1 - iFi iPower 5V 2.5A, low noise
- Power 2 - SMPS300RS from Connex Electronic, 36V low noise smps
- 230V relay board for enabling amplifier
- rotary encoder with button KY-040 360 (soldering capacitors for better detection)
- optical toslink to coaxial SPDIF converter from aliexpress
- IR receiver TSOP31236 from Vishay, 36 kHz
- LED matrix display 8x40 LEDs assembled from 8x8 module + 32x8 module. Module size is 32x32 mm. Control chip is MAX7219
- metal box from ezk.cz (drilled holes for cooling and screwing components)
- front panel cut by laser from plywood. Thanks Fablab Brno
Software:
- volumio (of course
) - plugin es9028q2m (this Audiophonics DAC haven’t native support on volumio)
- plugin Amplifier Switch (I will need modification for KODI, because this plugin can detect playing from volumio but not from KODI, or SPDIF)
- plugin KODI Krypton
- plugin Spotify
- plugin Youtube Playback
- plugin IR Remote Controller (added my own Xiaomi remote controll)
-plugin Rotary Encoder (I will need modification for better volume control) - Luma.LED_Matrix control led matrix display (python)
- (some python weateher and forecast library for displaying on LED matrix display)
