Some more smartbook internals (big pictures!)

As requested I took my quality piece of tablet apart again to make some more pictures (especially of the daugtherboard). This time I did not downscale them to 800×600, so beware of the 5 megapixels!

This is the backside of the daugtherboard, the “press-on” connector connects to the frontfacing camera. Sticking out from below the battery is the ribbon cable going to the mainboard.

The daughterboard with the ribbon cable to the mainboard removed.

The ribbon cable going from the mainboard to the daughterboard is below the glued-in battery.

Anything else you want to see? Please don’t make me remove the battery…. ;-)

Smartbook Surfer internals (iBreakIt…)

After taking a look at the software i could not resist to take a peek inside the tablet.
I only had to undo 4 screws at the back and then i could slide around the tablet with a screwdriver to open it and reveal the inside:

Connectors on the left side (bottom to top): microSHDC slot, miniHDMI, headphone, miniUSB, power button, DC in

After removing the cable coming from the touchscreen we get a view of the CPU, RAM, flash area:

From there it’s just a short trip to the wifi chipset (Atheros R6000):

Which is connected to this piece of Antennagate:

Smartbook Surfer

Marktkauf (a German supermarket chain) sells a stripped down version of the Smartbook Surfer ( It was quite difficult to get my hands on one of these. Because there is not a single Marktkauf in Berlin one of our poor trainees had to go out of Berlin (by train….).

The bad news first, it’s a pretty disappointing piece of kit. Even the online shop of Marktkauf disagrees with the printed Marktkauf commercial about the number of USB ports, etc. Here are the actual specs of the device i received:

160 MB RAM (not 256 MB, although there are two 128 MB DDR2 RAMs), 1 x miniUSB (not 2x), 1 x microSHDC slot (not 1x miniSD), 1 x miniHDMI (not 1 x HDMI), 1280×720 HDMI out (not 1920×1080 HDMI out), 720p Videoplayback (no 1080p), 2GB Flash but only around 1.4 GB are usable as internal storage (the device itself only shows 300 MB available to the user)

It runs Android 2.1, but it is really slow (what did you expect from a ARMv6 cpu?). The CPU should be running at 720Mhz which i cannot confirm yet. To dmesg it looks like 500 Mhz: “### CORE CLOCK (500000000 Hz), BUS CLOCK (166000000 Hz) ###”.

And “cat /proc/cpuinfo” says pretty much the same:

Processor       : ARMv6-compatible processor rev 6 (v6l)
BogoMIPS        : 499.71
Features        : swp half thumb fastmult vfp edsp java

The “touch”screen should be renamed to “press”screen because you have to press pretty hard to get it to recognize your input.

The builtin speaker is plain crap! It sounds awful, the headphones are fine though….Until! the device went to sleep for the first time, afterwards you will only hear very unpleasant highpitched static! Which really hurts when you have the headphones in use…. :-(

It features a frontfacing camera. You might “Wohooo!” first, but then you find out that you can only take photos with it or make black (not black and white!) videos with it. Then you think about….video calling…and install Fring..just to be told that because of device limitations you cannot make video calls.

Softwarewise it doesnt get much better. Quite often you are greeted by the “Force close” dialog. The tablet comes with a Skype lite beta client installed which unfortunately does not fill the full screen. Did maybe somebody rip it from some phone? ;-)

But after all the software situation is a good thing! Mainly because when you connect to the device with adb you are ROOT! Which is quite nice because you can access anything on the device. That way i was able to copy the to my Nexus One and install it. :-)

Of course it is a Skype lite (meaning calls with cost credits and go over gsm) but chatting seems fine. UNTIL…you get a chat message while the app is not running in foreground. Then skype eats 100% cpu and freezes the phone, forcing you to take out the battery.  Exactly the same thing happens on the tablett, skype rockets to 100% CPU making it even slower.

I would not recommend this tablet to anybody who wants to actually use it! For playing and hacking it’s fine though. :-)
