##### software and other stuff for my personal internet radio side project
# WORK IN PROGRESS
---
### what have i done:
My father tidied up his basement and found a *Loewe Opta R115* radio. It worked but had an annoying noise in the background and along with the fact that UKW (FM), "Ultrakurzwelle" will be turned off in the future, I decided to rip out all of the stuff and turn it into an internet radio.
It took quite a while. But now I reached a step in which the software and hardware is usable!
I try to document everything, so if you want to recreate this (aka. wake up the dragon): Good luck 🍀
This is no step to step instruction, so you should take your time and think yourself.
---
### hardware i used 🕹
- Raspberry Pi 3 Model B V1.2
- [1024x600px Display with HDMI](https://de.aliexpress.com/item/32700714288.html)
- cheap USB Soundcard (3.5 plug on RPI is crap)
- Amplifier with TPA3116D2 (have to check it out first, if it works fine)
- Monacor SP-13/4 speaker
- MeanWell RS-75-12 power supply (hope it delivers enough power for everything)
---
### how i use/make/run that:
You can run the radio software as standalone on your desktop, buts that a bit stupid, because there are way better tools to play internet radio on your pc.
#### prepare 🥧
[all commands in your user space: `/home/pi` unless its explicit declared]
1. flash [Raspbian Lite](https://www.raspberrypi.org/downloads/raspbian/) on a micro sd card
2. `touch ssh` in the root dir on the micro sd card
3. connect via ssh and run `raspi-config`
- System Options > Wireless LAN
- System Options > Password
- System Options > Boot / Auto Login > Console Autologin
3. remove boring booting stuff (optional)
- add `disable_splash=1` at the end of `/boot/config.txt` and save
- add `logo.nologo quiet` and change `console=tty1` to `console=tty3` in `/boot/cmdline.txt` and save
4. install everything needed
- `apt update`
- `apt upgrade`
- `apt install --no-install-recommends xserver-xorg x11-xserver-utils xinit`
(i know, i could use framebuffer with pygame, but I want to grab the pygame window over ssh and therefore I need xserver)
- `apt install git python3-pip vlc imagemagick pulseaudio libsdl-ttf2.0-0 python3-rpi.gpio`
5. `dpkg-reconfigure tzdata` and set your correct location for time
6. `git clone https://github.com/p4cx/optaradio.git` in your user directory `/home/pi`
7. run `pip3 -r install requirements.txt` in the freshly cloned optaradio repo
8. grab an api url from [openweathermap](https://openweathermap.org/) and paste it into `nano weater.cfg` - it should look like this: *http://api.openweathermap.org/data/2.5/weather?q=munich&units=metric&appid=1234567890abcdefghijklmnopqrstuv*
Attention: get sure, that units is metric: "units=metric".
9. `./optaradio/build.sh` to get fonts and emojis from external repositorys
-- have to test this
8. create a crontab for autostart
- `sudo crontab -e`
- insert ```@reboot sh /home/pi/optaradio/radio_startup.sh >/home/pi/optaradio/logs/cronlog 2>&1```
9. test it and if it runs: be happy
#### developing 💻
- activate X11 fowarding on your host machine (sshd config)
`ssh pi@x.x.x.x -Y` on your machine and you will get the pygame window on your desktop
- how do get radiothumbnails on the pi? Copy it manually with filezilla!
#### gpio usage 💡
| USAGE | PIN | PIN | USAGE |
|:---|---:|:---|---:|
| Power for all buttons | __3V3__ | __5V__ | -- |
| Favourite button 1 | __2__ | __5V__ | Power for rotary encoder |
| Favourite button 2 | __3__ | __GND__ | Ground for rotary encoder |
| Favourite button 3 | __4__ | __14__ | Rotary encoder button |
| -- | __GND__ | __15__ | Data channel rotary encoder |
| Favourite button 4 | __17__ | __18__ | Clock rotary encoder |
| Favourite button 5 | __27__ | __GND__ | Ground for relais |
| Favourite button 6 | __22__ | __23__ | Channel 1 for relais |
| -- | __3V3__ | __24__ | Channel 2 for relais |

#### run the 🐍 radio software
1. `cd ./optaradio`
2. `python3 ./init.py`
#### control optaradio
basic idea of controlling the radio: Like iDrive from BMW, rotate the wheel (in my case the KY-040 rotary encoder) to go up and down und press it to activate menu entry.
**control on desktop:**
- `return`: input
- `up`: up
- `down`: down
- `1`-`7`: Favourite buttons
- `q`: go back
- `w`: audio on/off
- `e`: LED on/off (future project)
- `r`: settings
- `ESC`: exit
**control with real buttons:**
- look at gpio usage, it should be self explaining
#### build 📻
1. get an old radio
2. get rid of all old crap inside
3. put a nice lcd and other fancy electronic stuff inside
4. jump in 🌙 light around the radio
5. squeeze your Raspberry Pi in the housing
6. turn it on and have fun
