# Project Overview
|
|
This is my first pass at building myself a small, portable, decent sounding digital audio player based around a raspberry pi zero and some additional hardware along with a 3d printed case.
|
|
|
|
My goal is to build myself a music player I can carry as my primary listening device that sounds good, can carry a large portion of my music library, has a simple user interface, has a more powerful backend interface, and does not cost a fortune.
|
|
|
|
For this first iteration, I have selected three HATs - a display hat with d-pad and utility buttons, a digital audio board, and an uninterruptible power supply board with battery. The selections of the hardware chosen was based more on availability at the time of ordering than any in-depth research in to the pros and cons of each device amongst its peers. As it turns out, there are a few GPIO pin assignments that two or more of the HATs will be trying to use for their own devices (ha) so I'll have to bodge that wire when I get to it.
|
|
|
|
The other hardware consists of a raspberry pi zero w board, a 32gb micro sd card, a micro-usb to usb-a plug cable, and a 256gb usb flash drive. The flash drive will be the music library storage and will be externally accessibly, should I want to remove it to modify the library contents on a system with a faster storage bus going for it. also, I could carry around a tiny fake pleather cassette carrying case that had a couple dozen usb flash drives in it and have literally terabytes of high quality music at my disposable. tres chic!

|
## initial setup
|
|
wrote raspbian image to sd card
|
|
|
|
added empty file `/boot/ssh`
|
|
|
|
added file `/boot/wpa_supplicant.conf`:
|
|
|
|
```
|
|
country=US
|
|
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
|
|
update_config=1
|
|
|
|
network={
|
|
ssid="WIFI_SSID"
|
|
scan_ssid=1
|
|
psk="WIFI_PASSWORD"
|
|
key_mgmt=WPA-PSK
|
|
}
|
|
```
|
|
|
|
booted pi
|
|
|
|
logged in via ssh
|
|
|
|
changed passwd
|
|
|
|
`sudo raspi-config`
|
|
|
|
- set up locale
|
|
|
|
- disable wait for network at boot
|
|
|
|
- resize filesystem in advanced
|
|
|
|
reboot
|
|
|
|
logged in via ssh
|
|
|
|
confirmed filesystem resize
|
|
|
|
`sudo apt update && sudo apt upgrade -y && sudo apt install tmux usbmount vim`
|
|
|
|
`sudo vim /etc/hostname`
|
|
|
|
changed to soundslab
|
|
|
|
shutdown -h now
|
