Software for audio LAN installation with hacked retro alarm clocks and websockets

requirements

python3

https://www.python.org/downloads/

for midi input (so the server side)

pip3 install mido

maybe you will need this backend for mido too

pip3 install python-rtmidi

for websockets to communicate to the radios in LAN (for the server and the clients)

pip3 install aiohttp

for the web interface

pip3 install aiohttp_jinja2

for playing the music files

pip3 install pygame

after having installed the required python libraries you can run with

python3 server.py or chmod +x the file to make it executable.

The server will be listening to any incoming midi device that is connected (before boot). It will then broadcast certain commands depending on the incoming midi msg through websockets.

python3 client.py will launch a client that receives the command via websockets

Web Interface

Once the server is booted visit

http://localhost:8080

on any browser to open the web interface to monitor and manage the alarm clocks.

troubleshooting

the clients are not connecting to the server?

• Make sure the laptop is connected to the router network. SSID is "nacho"
• Make sure the performance router is ON and the computer running the server is connected to it
• Make sure the computer running the server has no firewall blocking the connections
• Make sure that the IP of the server is correct in the config.ini file:
  • first check your ip addres:
  • then make sure the config.ini file has the same ip you just checked:

A single radio is not connecting?

• Once you spot which radio is not connecting you do 2 things.

1. Turn the radio off and then on again. It should work.
2. If the above doesn't work you can force it to connect manually. Do as follows: - Open the terminal and log in to the specific alarm clock (let's assume alarm clock 8 is the target): ssh ubuntu@radio8.local the type the password: francesca Once logged in type the following command: sudo systemctl restart radio.service Then radio8 will appear as connected in the web interface.
