DSD kuaj: DSD64, DSD128 & DSD256

Kauj Ruam 1: Cheeb Tsam

Koj tuaj yeem yuav lawv feem ntau los ntawm Audiophonics lossis los ntawm Volumio

www.audiophonics.fr/fr/dac-diy/… 11966.html (AK4495 DAC); https://www.audiophonics.fr/fr/accessoi … 11433.html (Kali reclocker);

www.audiophonics.fr/fr/raspberr… 12641.html (RPi 3)

Cov cai tswj fais fab:

www.audiophonics.fr/fr/alimenta… 12220.html (RPi zog)

www.audiophonics.fr/fr/alimenta… 11486.html (Kali zog)

www.audiophonics.fr/fr/alimenta… -4381.html (lub zog rau lub suab tso tawm theem los ntawm DAC)

Transformers:

www.audiophonics.fr/fr/transfor… -3504.html (rau DAC);

www.audiophonics.fr/fr/transfor… -6122.html (rau RPi thiab kali - tab sis yog overrated ntawm lub zog, zoo dua pom ib qho ntawm 30 - 45 VA);

LCD hd44780:

Case: Kuv siv rooj plaub qub los ntawm lwm qhov haujlwm tab sis koj tuaj yeem ua ib lossis yuav ib qho hauv internet kom haum.

Nyees khawm:

Lub zog khawm:

Laub khawm: 5 khawm khawm kom haum rau koj rooj plaub;

IEC Base EMI/RFI lub suab nrov lim 230V 6A nrog Fuse Holder: https://www.audiophonics.fr/en/iec-inlets/iec-base-emi-noise-filter-230v-6a-with-fuse-holder-p -11615.html

Kauj Ruam 2: Txhim Kho Software: Volumio

Muaj qhov sib txawv pub dawb uas koj tuaj yeem siv tau tab sis kuv xaiv Volumio vim tias nws muaj DSD txhawb nqa thiab plugins ua kom yooj yim rau kuv ua haujlwm.

Xav paub ntau ntxiv txog Volumio software ntawm no:

Yog tias koj tsis siv nws ua ntej, rub tawm thiab rho tawm Win32DiskImager.

Luam cov ntawv zip uas rub tawm thiab sau rau ntawm daim npav SD. Tsim lossis luam cov ntaub ntawv hu ua ssh hauv /khau raj yog tias koj xav nkag mus rau koj li RPi ntawm SSH ("Rau kev nyab xeeb vim li cas, SSH yog neeg xiam oob khab ntawm txhua lub khoos phis tawj tom qab 2.199") - tus neeg siv yog volumio thiab lo lus zais tseem yog volumio.

Nyeem cov ntaub ntawv:

Ntxig daim npav SD hauv RPi thiab txuas ntawm wireless lossis ethernet.

Nruab thiab teeb tsa GPIO Buttons plugin.

HD44780 LCD plugin tsis tau teeb tsa los ntawm lub neej ntawd tab sis koj tuaj yeem nruab nws zoo li qhov no (ua tsaug rau Saiyato uas tsim lub plugin no thiab rau Gvolt uas qhia kuv yuav ua li cas rau nruab nws):

Tom qab txuas mus rau Volumio ntawm ssh ua qhov no:

1. Rub lub pob plugin

wget

2. Tsim cov npe rau unzipping lub pob plugin

mkdir volumio-hd44780-plugin

3. Unzip lub plugin pob rau cov npe tsim tshiab

miniunzip volumio-hd44780-plugin.zip -d volumio-hd44780-plugin

4. Hloov mus rau hauv phau ntawv teev npe nrog cov ntaub ntawv unzipped

cd volumio-hd44780-plugin

5. Nruab lub plugin

volumio plugin nruab

Kho lub plugin.

Kauj Ruam 3: Kho Kho Vajtse

Ua ntej yuav tsum txhim kho cov hloov pauv thiab cov ntsuas hluav taws xob nyob hauv qhov chaw thiab txuas lawv mus rau lub zog khawm; ntxiv iav fuse (ncig 1.25A / 250V) mus rau 220V lub qhov (socket).

Ntsuas DC qhov ntsuas hluav taws xob thiab kho qhov ntsuas hluav taws xob yog xav tau nws (yog tias koj siv cov tswj kev hloov pauv): 5Vdc rau RPi thiab Kali Reclocker thiab +/- 15Vdc rau DAC.

Txuas Kali rau Raspberry Pi thiab tshem tawm jumper los ntawm Kali yog tias koj siv cov ntsuas hluav taws xob sib txawv. Txhawm rau pub nrog lub zog Raspberry Kuv txiav USB 2.0 Txuas Txuas Txuas uas txhawb 3Amps. Rau Kali Kuv tau ua ib kab.

Txuas LCD rau Kali Header:

SDA to pin 3

- SCL to pin 5

- Vcc pin 4

- GND to pin 6

Kuj txuas cov nyees khawm rau Kali siv cov ntxaij lim dej tiv thaiv zoo li koj tuaj yeem pom hauv daim duab qhia chaw;

Txhim kho qhov chaw DAC thiab txuas lub xov hluav taws xob thiab lub suab tawm rau RCA. Txuas I2S los ntawm DAC mus rau Raspberry Pi - rau qhov kev siv zoo dua tiv thaiv kab hluav taws xob lossis ua rau koj tus kheej (nrhiav cov kab koj xav siv, npog nws nrog cov ntawv txhuas, ntxiv cov kab me me rau cov ntawv ci thiab npog dua nrog kab xev txuas. ntawv ci rau hauv av).
