1. arduino yun 101 ###

before starting, assure we have:

arduino ide version 1.5.6-r2: http://arduino.cc/en/main/software#toc3

configuration: http://arduino.cc/en/Guide/ArduinoYun

let's become confident with the board

arduino.local does not always revole, safely to use the ip number (192.168.240.1, for initial configuration).

to log into the yun via ssh (from mac-osx shell): ssh root@192.168.1.13

    #---------------------------------------------------------------------
    # install the video stuff on the yun
   opkg update
   opkg install kmod-video-uvc
   opkg install kmod-video-pwc
   opkg install kmod-input-core
   opkg install libjpeg
   opkg install fswebcam
   wget http://www.custommobileapps.com.au/downloads/mjpg-streamer.ipk
   opkg install mjpg-streamer.ipk
   opkg install ffmpeg
   opkg install ffserver
   opkg install python-openssl
   #---------------------------------------------------------------------

after each installation step, to see free space remained on the hard disk:

   root@Arduino:~# df -h
   Filesystem                Size      Used Available Use% Mounted on
   rootfs                    7.5M      4.9M      2.6M  66% /
   /dev/root                 7.0M      7.0M         0 100% /rom
   tmpfs                    29.9M    372.0K     29.5M   1% /tmp
   tmpfs                   512.0K         0    512.0K   0% /dev
   /dev/mtdblock3            7.5M      4.9M      2.6M  66% /overlay
   overlayfs:/overlay        7.5M      4.9M      2.6M  66% /
   /dev/sda1                 7.4G    848.0K      7.4G   0% /mnt/sda1

see what is already mounted:

   mount

see which distribution:

   root@Arduino:~# cat /proc/version
   Linux version 3.8.3 (federico@smilzo) (gcc version 4.6.4 20121210 (prerelease) (Linaro GCC 4.6-2012.12) ) #8 Mon Aug 19 16:22:39 CEST 2013

to see the stream (from the os/x): open "http://arduino.local:8080/?action=stream" in a browser after running (on the yun via ssh):

   mjpg_streamer -i "input_uvc.so -d /dev/video0 -r 640x480" -o "output_http.so -p 8080 -w /mnt/sda1"

see if python server is running (from the os/x), after running "python -m SimpleHTTPServer" (on the yun via ssh):

   nmap 192.168.1.13
   
   Starting Nmap 6.40 ( http://nmap.org ) at 2014-04-30 13:03 CEST
   Nmap scan report for 192.168.1.13
   Host is up (0.19s latency).

   Nmap done: 1 IP address (1 host up) scanned in 39.77 seconds
