Gobandroid

When i got my first Android Phone ~2 months ago there was no goban for android yet - but i wantet some - so i started the opensource project gobandroid ( goban + android ;-)
I got a lot of feedback, that's one of the reasons why i am writing this blogpost. First of all thanx to the first contributor Ruth Hinckley aka Lironah for with first images ( i started with single color circles and lines ;-) See the difference:





Second thanx to the potential contributor shay raikin who wants to implement gnugo !-)
And last but not least thanx to all the mails with bugreports/ideas and greetinx.
There are not much features yet but even with these little featureset some users are just happy with it e.g. to write down games and save them to SGF.
Tonight I implemented something new - the skins are now saved to SD-Card with applications called gobandroid skinstaller ( skin + installer ;-) - These applications uninstall after they did the job of copying images to the sd-card - so there is not much Application Space is needed. Application Space is actually a big issue on android at this time. I have a lot of space on sd-card but lack space where i can install application. This needs to be fixxed on android but until then I'm going this workaround.




here is the code of gobandroid: http://github.com/ligi/gobandroid

the code is GPL licenced

and here is the code of the installer ( perhaps the uninstalling or the resources to SD-Card part is interesting for someone ) : http://github.com/ligi/gobandroid-skinstaller-lironah/

Controlling Mikrokopter with a SpaceMouse on an OpenWrt Router

I improved my SpaceMouse MikroKopter flying setup so that it's now more practical. In the old setup for piloting the MikroKopter with a SpaceMouse ( look here) - I used my notebook for running Riddim. This mainly had 3 drawbacks:
- setup time until i can start flying with this setup was very high
- not reliable enough ( I install software and do experimental stuff on my notebook too often to believe it could be a reliable MultiKopter Controller )
- in the notebook setup piloting was only possible when sitting

In the new setup i use one openwrt router ( asus wl500g premium ) to run the riddim software:
side top

The Datalink to the Mikrokopter is done with ZigBee Pro - which is connected over one MK-USB to the router ( later i can get rid of the MK-USB and use one of the 2 native serial ports in the router to save weigth and power).
The keyswitch to start the mikrokopter and the other switches are connected to an mini gamepad i bought for ~5Eur and took apart to connect wires.




The whole thing is powered by a 2S LiPo ( to ensure the 7805 is not getting to hot).

résumé

Pros:
- very intuitive ( you move the mouse as you want your QuadroKopter to fly )
- one free hand - only one hand needed for flying ( so you have one hand free for operating other functions, for a cigarett, a mobile phone ,a tissue , ... )
- keyswitch to start the Multikopter often lets spectator smile ;-)

Cons:
- router needs ~1min to boot ( i deactivated some stuff in the init.d allready but i have some more options left i can try like boot_wait_time, removing modules i dont need , ... - i hope i can get it ready in <30s )
- landing ( more touch down than soft at the moment with preasure sensor )
- not really suitable for acrobatic flight
