Eldin ring is a project where an old phone from a phone booth is being trasformed into a device that can play audio.
This project is using a
All pinout uses the BCM layout
adafruit i2s audio bonnet used pins: 18 19 21 16 20
ringer_pins = [13] phone_pins = [5,6] keypad_pins = [4,17,27,22,23,24,25]
First, plug in the phone booth. After about 1 min 30 seconds the bell should ring signifying that it is up and running.
The phone booth emits wifi called Phone Booth. Once connected, open a browser and connect to http://192.168.4.1 in the url search bar. You will see a website with a bell icon.
When you hold down the bell icon, it rings the bell. When you let go it stops the bell. If you close the browser without letting go on the bell it will continue to ring until you open the app and click the bell again or pick up the phone.
The bell only rings when the phone is hung up.
Power off the device. Take out the usb drive and replace the mp3 files on it. Plug in the usb drive and power on the phone booth. If the phone booth does not have a usb drive when it is turned on it will not boot. power off the device, re-plug in the usb drive, and the phone booth should turn on in 1 min, 30 seconds(ish).
The phone is silent until the handset is picked up. When handset is picked up it plays welcome.mp3
if a key is pressed, welcome.mp3 is stopped and it starts playing the audio associated with the pressed key. once the song is over, the payphone will be silent.
any time the payphone is hung up it goes silent.
