Project McIntosh - By Volumio

Hi everyone, I’m an audiophile and I have a passion for electronics and information technology

this is my voluminous project…

Hardware:

LCD 9,7 IPAD3
Controller LCD
Raspberry P4 - version 1 GB
Apple Remote A1294
self-made cabinet
DAC PIFI v2.0
preamplifier output - tube.


Working

I had problems with the resolution of the monitor so I modified the file from the boot
as:

initramfs volumio.initrd
#GPU_MEM=32
max_usb_current=1
dtparam=audio=on
audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
hdmi_force_hotplug=1
force_eeprom_read=0
hdmi_cvt=1024 768 70
hdmi_drive=1
hdmi_mode=87
hdmi_group=2
#dtoverlay=vc4-fkms-v3d

max_framebuffer_width=1920
max_framebuffer_height=1080
framebuffer_width=1024
framebuffer_height=768
include userconfig.txt
#### Volumio i2s setting below: do not alter ####
dtoverlay=hifiberry-dacplus


#### Volumio i2s setting below: do not alter ####
dtoverlay=hifiberry-dacplus



#### Touch Display gpu_mem setting below: do not alter ####
gpu_mem=32

#### Volumio i2s setting below: do not alter ####
dtoverlay=hifiberry-dacplus


#### Volumio i2s setting below: do not alter ####
dtoverlay=hifiberry-dacplus

with the WINSCP program
which helped me for the changes and by first enabling SSH for volumeo , I replaced the files in the folder

the default album-art (when nothing is playing) is the default.jpg/png file in /volumio/app/plugins/miscellanea/albumart/

demo:

I’m still working on improving some things, as soon as I can I’ll post the remote control code and other videos.

for now, hello everyone.

Nice project, keep us updated.

do not change the file config.txt, please put your additional lines on userconfig.txt, they will be preserved on system update (otherwise you will lose them)

great I will try

ok, post new updates!

I also add the configuration code of the Apple Remote A1294
this setting is the best you can get for my PIFI DAC V2.0 dac with IR

this is the model
pifi-dac

configuration port for the IR pin is gpio is 26, to allow the remote control to receive commands.

I have to make a parenthesis the menu key does not work, it works as if it were the play button. ( I’m working on it.)

end remote

this file must be copied to / data / INTERNAL / ir_controller / configurations
to create a new folder “Apple Remote A1294” after which create a file with the name “lircd.conf” without quotes and paste the code into it.
this can be done with WINscp with SSH enabled.

as soon as I can I will put other updates
thank you all for now …

if there are any suggestions or updates that can help me improve everything, they are well accepted … thanks.

this is the 3d drawing of the project
