October 11, 2013 by aubreykloppers

Over the next couple of weeks I will post some tips and tricks for the Raspberry PI:

Enable Analog Out:

amixer cset numid=3 1

Testing your Sound:

Left:

speaker-test -t sine -f 440 -c 2 -s 1

Right:

speaker-test -t sine -f 440 -c 2 -s 2

Connect via WiFi (and disable LAN):

vi /etc/network/interfaces

auto lo
iface lo inet loopback

#auto eth0
#iface eth0 inet dhcp

auto wlan0
iface wlan0 inet dhcp
wpa-ssid “<name of your ssid>”
wpa-psk “<your secret key>”

Connect via WiFi (Part 2) with Wheezy:

wpa_passphrase “<SSID>” <PASSPHRASE> >> /etc/wpa_supplicant/wpa_supplicant.conf

Quick enable proxy support:

export http_proxy=”http://”<ip:port>&#8221;

Upgrade packages:

apt-get update
apt-get upgrade

Projects:
