Set up a Chromecast from a Linux PC, without an Android or iOS mobile device and without Google Home
#!/usr/bin/env bash
# castanet.sh: Script to connect a chromecast to a WiFi network.
#
# Allows you to put your Chromecast on WiFi and do Chromecast initial setup
# without using the Google Home app at all, just using a normal Linux computer.

# You do need your Chromecast to be on Ethernet, or (untested) to join its setup WiFi
# network with your PC, and you also need to find out its IP yourself with e.g.
# Wireshark.

Magic Potion | How to setup an Asus WL-520gu with OpenWRT for Sound
Note these instructions are all based on the mightyOhm articles. This is a little bit different because I wanted to get alsa sound working (instead of dsp) so that I could overlay effects

What to do
==========
install mightyohm trx by blind flashing
setup network and wireless and dhcp
setup the banner for fun
