My opinion about Hannspree Hannspad SN10T1

During Linaro Connect Q3.11 I had occasion to play with few Android tablets. Andy Green pointed me to Hannspree Hannspad at Ebuyer UK (as he has one at home) which looked as nice deal so I bought one. It arrived two days later so I was able to play with it during conference.

Tablet was quite fast and nicely responding but… screen was disaster 🙁 Problems with touch screen, very poor angle views made using it very uncomfortable for browsing web or watching videos. Later I found out that there are two versions of Hannspad tablet: 1633 (which I got) and 1653 (with usable, bright display).

I was able to play with Froyo (was installed by default with some crappy tools), Gingerbread (community build of Cyanogenmod) and also with Honeycomb which is what I used for most of time. The fun of hacking Hannspad is that there are no kernel sources released by vendor so most of custom ‘ROMs’ are made for Viewsonic GTablet. Effect is that soft touch buttons does not work, volume buttons are reversed and some other issues exists while device is usable. But thanks to ab73 from SlateDroid forum most of them was solved and even more — Search button was found below Back one 🙂

Today I sold it. Was it worth buying? Definitely no, but it was good opportunity to check do I need such device. For day to day use rather no, but it was nice tool to browse web from couch or checking social networks. And Freerunners HD were flying 😉

But I plan to buy next tablet one day. Something with more square screen would be nice as I mostly used it in portrait mode to browse web and screen was too narrow for it. Who knows — maybe Amazon Kindle Fire or Barnes & Noble Nook Color 2 (which was expected to be released in September too). 7″ sounds better then 10″ due to size. But for sure nothing less then 1024×600 resolution (1024×768 or 1024×1024 would be perfect).

Error: Boot loader didn’t return any data!

Today I upgraded my virtual machine from Ubuntu 10.04 ‘lucid’ to 11.04 ‘natty’ + 3.0 kernel from 11.10 ‘oneiric’. For first time I used official way for upgrades and did that step by step (lucid -> maverick -> natty) with reboot on each step. Each upgrade ended with reboot of vm.

But fun started when I wanted to install 3.0 kernel from 11.10 ‘oneiric’… Installation went fine — mostly due to Alex’s comment to my blog post about it. But after reboot machine did not wanted to boot at all ;(

xm create NAME” resulted in “Error: Boot loader didn’t return any data!” message… After some googling (as I never was XEN administrator) and experiments I got what was wrong. We use ‘py-grub’ to boot VMs and this tool uses “/boot/grub/menu.lst” to get information which kernel to boot. But Ubuntu systems are using “/boot/grub/grub.cfg” due to grub2 instead of grub-legacy.

Anyway I updated menu.lst by hand and VM booted fine. Need to remember for next kernel update 😉

My devboards lost power source

When I returned from Linaro Connect Q3.11 I noticed that none of my Pandaboards are on. I though that powered them off before leaving but two days later I needed at least one online. Power cycling PSU did not helped so I took 5V/3A one from box and got board running leaving old one for inspection later.

Today I disconnected all cables from PSU and opened it:

This does not look good… So time to buy another 100-200W old pc power supply and adapt for use with developer boards:

This big white connector had 12V, GND, 5V lines which allowed me to charge most of my developer boards and usb hubs.

It served well for 2.5 years — now have to recycle it…
