🎧🔥🖨️🖼️ print out the album art music you're currently listening to
Uses Last.fm to get the tracks you're listening to and then prints them out on a thermal receipt printer.
here's a vid of it working: https://www.youtube.com/watch?v=ElmxS7iTNQ4
I did a talk about this, here are my slides: https://docs.google.com/presentation/d/1gCsklfmLf14PuasJexWyZcEoaQp72HyZ2LuIPDJe1Ys/edit
- thermal printer
- 57mm thermal paper
- Arduino Uno (Works with other devices that can use serial port too use the corresponding RX and TX)
- Arduino IDE
- some jumper wires
- 9V power supply (splice wires and shove into thermal printer)
- Last.fm API key
- upload the
StandardFirmataexample code to your Arduino Uno (File/Examples/Firmata/StandardFirmata->Upload) - set-up your thermal printer
you will probably need to tweak the settings for your printer, see the thermalprinter module comments
- add environment variables. (Copy
.env-sampleto.env)
LASTFM_API= # sign-up for a key at http://www.last.fm/api
LASTFM_SECRET= # also at http://www.last.fm/api
LASTFM_USERAGENT= # this is to tell last.fm who is requesting info
LASTFM_USERNAME= # your last fm username to track what music is playing
PRINTER_USB= # this is where the arduino is mounted at, see your Arduino IDE (Tools/Port)
PRINTER_BAUDRATE= # hold the power button and plug the power in, the baudrate is printed on the test page
PRINTER_ROTATION= # this changes the orientation of the print, 180 is upside down for example
- install non-node dependencies: GraphicsMagick
sudo apt-get update
sudo apt-get install graphicsmagick
- install node dependencies
npm install
listen to music and then run the script:
sudo node main.js
everytime Last.fm picks up a new song streaming it'll print it out!
you probably need to run a root to get access to the USB port
