The ‘JukeJack’ is a project of mine to create a ‘Diplomatic Jukebox’. Me and my mates used to choose which bars to drink in when we were younger based on the quality content of their jukeboxes. My favourite was the Old Ale House in Truro that had all the Led Zeppelin albums on!
These JukeBoxes are now long gone and were briefly replaced by the ‘web connected’ jukeboxes but they too have now disappeared. Our local The Ship Inn in Porthleven can often be seen passing round an Ipad for punters to select their favourite tunes on Spotify.
I thought this could be improved by using a web app on your phone with the added functionality of other people in the pub ‘upvoting’ or ‘knocking off’ tunes from the playlist, therefor creating a ‘peoples playlist’
Following some research i found the best way to do this is use a raspberry PI as a web server running Mopidy an extensible music server written in Python. Mopidy plays music from local disk, Spotify, SoundCloud, Google Play Music, and more and you can edit the playlist from any phone, tablet, or computer using a range of MPD and web clients.
The next addition would be to add functionality for users to be able to ‘tweet’ the song to the venue using this Twitter API libary https://github.com/lfcipriani/tweet-jukebox i have tested this and it works well but just needs some refinement. This adds great marketing value to venues using the app too.
To summarise –
- The venue would have a web connected PI with the software installed and a pro audio hat such as this https://www.hifiberry.com/products/dacplus/ connected to an amplifier.
- The customer connects to the ‘JukeJack’ network. The customer then tweets to the venues twitter account what song they would like played. The venue then tweets back to the customer that their track will be played after X amount of songs.
- To be worked out..Other customers can ‘upvote’ or ‘downvote’ the upcoming track. I think this functionality will have to operate independently from the twitter API
Below is the process of installment i will update this with a finished prototype very soon
Part 1
- SD Card adapter for micro SD card I didn’t have one so had to use this method
- https://www.stewright.me/2013/05/install-and-run-raspbian-from-a-usb-flash-drive/
- https://docs.mopidy.com/en/latest/installation/raspberrypi/
- Download the latest Jessie or Jessie Lite disk image from http://www.raspberrypi.org/downloads/raspbian/.
- Install the image to your SD card using these instructions https://www.raspberrypi.org/documentation/installation/installing-images/windows.md
- Install mopidy using these instructions
- https://docs.mopidy.com/en/latest/installation/debian/#debian-install
- Check mopidy works by typing ‘pi@raspberrypi:~ $ mopidy’
- http://raspberry-at-home.com/mopidy-spotify-client/
- Install sudo apt-get install mopidy-spotify https://github.com/mopidy/mopidy-spotify Edit config file to include your Spotify Premium Log In
- Config file here sudo nano /home/pi/.config/mopidy/mopidy.conf
- [spotify]username = ***************password = ***************enabled = truebitrate = 320timeout = 10cache_dir = $XDG_CACHE_DIR/mopidy/spotify
- JUKEJACK 1.0 – Issues, Roadmap
Part 2
- Changing hostname for Mopidy.
To change the hostname for Mopidy, we need to change the parameter hostname to 0.0.0.0
and uncomment the lines that are in the config file which you can see now. They are under http block.
- Opening Firewall in Raspberry PI if available.
If Iptables is blocking, we need run :
sudo iptables -A INPUT -p tcp -m tcp –dport 6680 -j ACCEPT
sudo /etc/init.d/iptables save
- Configuring Router with DDNS.
Here, we used Noip.com for DDNS service. We first created account on noip.com then we created a new domain. As our router supported Noip.com as DDNS service built-in , we could easily apply the DDNS service and connect our router with Noip.
Then, we need to add the required port 6680 and open it so that the port will be available through the internet. Now, we should be able to access Mopify from local network (http://RPI’s IP address:6680/mopify/ ) and also from the internet (http://alecsraspberry.hopto.org:6680/mopify/).
To run mopidy, you need to run :
$ screen mopidy –config ~/.config/mopidy/mopidy.conf
And tweet-jukebox :
$ screen node ~/workspace/tweet-jukebox/init.js
