This is my latest artwork:

Mobile workplace.jpg

Mobile work-place ;) Freerunner beeing charged from a modified USB hub using 5 AA batteries.

Full keyboard, mouse and external HDD connected!

Internet access wia UMTS dongle.

A special holder places the FR into a reflection-free angle.

Note the TUX penguin, that I have manually glued on the 'Windows-Keys'!

I have bridged the output power supply of the USB slots in the USB hub back to the 'input' line (where the FR plugs in). With a manual switch I can turn on/off this power feed. This might be some good lock that the good piece didn't blow off - it's a 20EUR DLINK hub.

The power supply are 5 AA NiMH accus, which deliver around 6.5V when fully charged. This is about the same voltage the comes from the external AC/DC power plug.

Using alternate browsers

Midori is nice...but not a fully usable browser. And loading pages over cellphone network is pretty slow. Therefore I use a ssh tunnel to a X-server at home and look at it via vnc. (I don't explain how to set-up an ssh account through dyndns here...)

at home type:

vncserver :30 -depth 24 -geometry 1280x1024
DISPLAY=:30 firefox &

on the FR in a first shell:

 ssh -L5930:localhost:5930 myaddress.dyndns.org

and in a second shell:

vncviewer localhost:30

Adding swap space on mmc card

In SwapSpace is descriped how you add a swap file on filesystem. This seems somehow complicated to me. I wanted to use my microSD card for swapping (it doesn't matter if it gets broken after 2 million read/write accesses). Also, I don't want the mmc card formatted with VFAT anyway, so I made a new partitioning:

/dev/mmcblk0p1               1        5129      500075   82  Linux swap / Solaris
/dev/mmcblk0p2            5130       81820     7477372+  83  Linux

and added in /etc/fstab:

/dev/mmcblk0p1          swap                    swap    defaults        0 0

doing a

 mkswap /dev/mmcblk0p1

once and a reboot and we're done.

See what 'top' says: the internal 128MB memory is almost always completely exhausted, with just one or two applications running. With 512MB swap space I can use Midori, tangoGPS, several terminals, the settings pages and so on all at the same time.

Mem:    120856k total,   116364k used,     4492k free,      172k buffers
Swap:   500064k total,    67696k used,   432368k free,    71764k cached
