In my case, I took the opposite direction. Instead of displaying the screen on a 49" TV, I have repurposed a 7" tablet as a Volumio kiosk:
Just got this setup recently and will see what needs to be fixed / improved while using it on a daily basis. The aim is to be able to browse music and control playback directly from it.
Here’s the configuration for those who are interested:
- Amazon Fire 7" (7th gen), flashed with LineageOS 14.1. The good thing is you can get these refurbished / secondhand for cheap. I got mine for less than 15 USD. The not-so-good thing is you would have to flash a custom ROM, otherwise it won’t show the Now Playing screen properly. Depending on the FireOS version that came with the device, you might have to open the case and short some pins under the heat shield to unlock the bootloader before you could flash LineageOS. Anyway, it’s amazing to see the developers sharing this kind of stuff over at xda!
- Install Fully Kiosk Browser, which is an awesome app that turns your device into a kiosk that displays a full-screen web page. Configure the browser to load
