Ikea Dragan Speaker Box

thingiverse

This is basically a frame to connect the two halves of an IKEA Dragan box with a magnetic door latch:\r\nhttps://www.ikea.com/de/de/catalog/products/40222607/\r\n(The magnet mount is called "flap" in the SCAD file, current size is 12x38mm with a hole distance of 27mm, feel free to customize this for your own magnets.)\r\n\r\nMy speaker cover I used for this project can be found here:\r\nhttps://www.thingiverse.com/thing:3268837\r\n\r\nI put a Raspberry Pi Zero W with Pimoroni's Phat Beat in it,\r\nhttps://shop.pimoroni.com/products/phat-beat\r\nadded a chinese RFID reader (less than 4 Eur),\r\nhttps://www.aliexpress.com/item/USB-port-EM4001-125khz-RFID-ID-Contactless-sensitivity-Smart-Card-Reader-support-window-system/32743649284.html\r\na membrane button pad (less than 1 Eur),\r\nhttps://www.aliexpress.com/item/1-2-3-4-Key-Button-Membrane-Switch-Matrix-Array-Keyboard-Keypad-Control-Panel-Pad-DIY/32915945543.html\r\na Visaton FRS8 M speaker (about 10 Eur) and made use of the wonderful piCorePlayer (with some home-grown Python scripts...):\r\nhttps://picoreplayer.org/\r\n\r\nVoila, a small Squeezebox with RFID-card-selectable playlists!\r\n\r\nFeel free to take the OpenSCAD file and modify as needed!\r\n\r\n### Python Scripts\r\nNow you're entering the experimental section - the uploaded scripts are made up of some hacked-together stuff that was extracted from another project... and I am currently unable to set up the whole thing from scratch (without breaking the current installation).\r\n\r\nThe "backend" is a python script which connects to the Squeezeserver and sends "play", "pause", etc. commands to it. On top there are two scripts, one is responsible for detecting button activity and the other reads input from the USB RFID reader to change the playlist.\r\nRFID reader source code is based on this: https://github.com/MiczFlor/RPi-Jukebox-RFID/blob/master/scripts/Reader.py\r\n\r\n** Squeezeserver **\r\nYour Squeezeserver needs to have playlists prepared with a matching ID in angle brackets. For example if you have an RFID card with ID "1234567890", you should create a playlist named "My cool playlist <12345678990>".\r\n\r\nAvailable playlists are read by the scripts only at startup - or when a specific "service" ID is read. This ID needs to be defined as "SERVICETAG" in the beginning of the script.\r\n\r\n** Prepare System **\r\n- install tiny core extensions (via web gui or from commandline tce-ab) :\r\n - python3.6\r\n - python3.6-dev\r\n - python-RPi.GPIO\r\n - compiletc\r\n\r\n** "Install" Scripts **\r\n- Create a workspace directory on /mnt/mmcblk0p2 as root or via sudo.\r\n- Change the owner of the workspace to tc:staff.\r\n- create a folder "radio" in /mnt/mmcblk0p2/workspace as user tc.\r\n- copy my Python scripts to /mnt/mmcblk0p2/workspace/radio.\r\n\r\n** Build evdev module (to access the RFID reader) **\r\n- download (and unzip) python-evdev from https://github.com/gvalkov/python-evdev to /mnt/mmcblk0p2/workspace \r\n- run "python3.6 setup.py build" in the unzipped directory.\r\n- copy new module folder evdev from "build" to /mnt/mmcblk0p2/workspace/radio.\r\n\r\n** Test it ... **\r\n- try to run everything manually -> go to /mnt/mmcblk0p2/workspace/radio and run startme.sh.\r\n\r\n- very likely to fix a lot at this point... there might be further Python module dependencies I've forgotten. Or worse... \r\n\r\n** Autostart **\r\n\r\n- Add startup command to /opt/bootlocal.sh:\r\ncd /mnt/mmcblk0p2/workspace/radio && ./startme.sh > /home/tc/squeeze.log &\r\n\r\n- Run "sudo filetool.sh -b" to backup this file to SD.\r\n- Reboot the Pi.
