This project is using various open-source components like Plasma Bigscreen, Mycroft AI and libcec with a modified KDE Neon img for the Raspberry Pi 4 to allow easy accessing content-related services on your TV.
KDE Plasma Bigscreen
A big launcher giving you easy access to any installed apps and skills. Controllable via voice or TV remote.
Bigscreen supports Mycroft AI, a free and open-source voice assistant that can be run completely decentralized on your own server.
Mycroft is using the Selene Open-source backend:
Note: While the Mycroft server is currently using Google STT engine, Mozilla DeepSpeech support has been started:
Help DeepSpeech to become the best STT by contributing to the Common Voice project:
Remote control your TV via CEC
CEC (Consumer Electronics Control) is a standard to control devices over HDMI.
Use your normal TV remote control, or e.g. this RC with built-in microphone for voice control and optional mouse simulation:
Download new apps (aka skills) for your Bigscreen or add your own ones for others to enjoy.
A completely open UI stack
for your own personal TV box
Enjoy Bigscreen without worrying about:
> Censoring of content.
> Selling of personal data.
> Intrusion of your privacy.
Raspberry Pi 4
ARM Linux machine for setting up your own Bigscreen box.
KDE Neon based
This img is using KDE Neon as its base to provide latest packages:
Control Bigscreen with your TV remote control.
