README

Rasberry Pi as TV controller

• Buy the meanest and leanest raspberry pi you can get. I got the Raspberry Pi 2 Model B with a 900MHz quad-core ARM Cortex-A7 CPU and 1GB RAM.
• A good browser (I use Firefox).
• Avahi for zeroconf / discoverablility.
• NGINX as web server.
• A python http server script.
• A tiny web page

To display a web page on the TV:

Note: Your network has to support mDNS. Some corporate networks will block that.

• Go to <pi-hostname>.local and a form will allow you to input a URL. That will start a broswer session with that URL.
• Use terminal: curl --data "url=https://www.librato.com" <pi-hostname>.local:8000

Fast setup

1. Install Raspbian Jessie.
2. Launch sudo raspi-conf and
3. Expand the filesystem
4. Set time zone, language, keyboard
5. Activate SSH access
6. Change the hostname
7. Set to auto-login directly to startx
8. Clone this repo and cd into it
9. Run sudo bash install.sh
10. Set the screen resolution: edit /boot/config.txt. This configuration works for me.
11. Last but not least, check the autostart.md file for ideas on auto-starting the browser to a specific URL and settings to stop the Pi from sleeping

Cloning

When all is set and done you can clone SD cards with rpi-clone. After cloning is complete, boot up the cloned Pi and change the hostname with raspi-conf.

Stlying

You can use CSS browser plugins to force Spaces to use a dark theme. For example Stylish has plugins for Chrome, Firefox, and Safari. It allows you to map specific URLs to custom CSS. Stylish has a social aspect to it; users can share CSS themes. I added a couple of Librato Spaces themes. There's also the Style Script plugin that works on iceweasel.
