Westinghouse H816L5 Clock Spotify ConversionBasically, If you own a 1960s Westinghouse H816L5 and want to install a RPI4 in it without chopping it up too much to use Spotify, this is for you. Or if you need to reprint a missing piece, these models might help you out.If you don't own one already and are a brave person that is great at printing supports, then you can try to print a new one from the replacement mockups I modeled. (I have never tried this, and if you do, please, please, let me know how it goes).https://github.com/MacGyverr/Westinghouse-Spotify-ClockOverviewI owned a broken H816L5 and wanted to give it some new life so I replicated the Westinghouse H816L5 clock in TinkerCAD to design parts for mounting a Raspberry Pi and a modern clock, transforming it into a Spotify speaker while keeping the original shell mostly intact.TinkerCAD Model: Westinghouse H816L5 Clock Conversion - WIPThe project involved some modifications to the original structure, you'll need to grind down the internal lip behind the volume knob. It uses Raspotify and Spotipy, controlled by a Python script. It features three rotary encoders for track control/shuffle, power/play/pause/volume, and playlist navigation.Hardware RequirementsRaspberry Pi 4MIC ULTRA+ (as an amplifier) Link3 Rotary Encoders3 WS2812B LEDsRotary Encoder #1 to GPIO pins 16, 12, 26 (Clock, Data, Button)Rotary Encoder #2 to GPIO pins 5, 6, 13 (Clock, Data, Button)Rotary Encoder #3 to GPIO pins 22, 27, 17 (Clock, Data, Button)Radio Setting ClockNew 4" Shielded SpeakerWS2812B to GPIO pin 10 (Data for LEDs)SoftwareRaspberry Pi OSRaspotifySpotipySpotify APIInstallation and SetupPrepare the Raspberry Pi:sudo apt-get -y updatesudo apt-get -y upgradesudo apt-get -y install git pip espeakConfigure Rotary Encoders in config.txt:sudo nano /boot/config.txt# Add the following linesdtoverlay=rotary-encoder,pin_a=16,pin_b=12,relative_axis=1dtoverlay=gpio-key,gpio=26,keycode=30,label="A"dtoverlay=rotary-encoder,pin_a=5,pin_b=6,relative_axis=1dtoverlay=gpio-key,gpio=13,keycode=48,label="B"dtoverlay=rotary-encoder,pin_a=22,pin_b=27,relative_axis=1dtoverlay=gpio-key,gpio=17,keycode=46,label="C"After editing, reboot and test with evtest.

(untested)The system is set to read only "Overlay" mode and reboots nightly for stability.It can be controlled by any computer or phone remotely via the normal Spotify App, it is using the Spotify API, there just is a custom program asking Spotify to make changes via the rotary knobs.I'm not a programmer, so after much trial and error the program works for what I needed it to do but not very well. If you can improve it or have an alternative I'd love to give it a try, feel free to fork my Github.Video of it in actionhttps://www.youtube.com/watch?v=2hyoNcoZj8I
