Hi pjc123, I am considering getting this USB stick. You mentioned that sometimes the stick doesn't get an IP address while booting. Does this problem still persist? Could you share your script to turn the stick on manually? Yes, it still has the issue, but the script fixes it. Actually the script r...

Re: Connecting free bVNC (Samsung Tab 2) to Pi

Is it possible that the tightvncserver on the Pi will not work with the bVNC client on the Android? I have used "bVNC Free" with tightvncserver in the past, so it does work. I don't remember my setup as it was a long time ago. Kind of useless on my small smartphone screen though, but I just wanted ...

Re: Rasberry Pi with Android controller

If you are simply asking for a way to communicate with the pi from an Android device, then yes, you could ssh from the Android device into the pi and run whatever programs on the pi that you create. ConnectBot is the de facto ssh app for Android, and it makes this very easy to do.

Re: Which case is best?

I have the first case and like it. It holds the pi nice and snug and has openings for all the various ports and connectors. The one I got from SB Components on Amazon is identical; it even has the same exact picture. You can read the reviews here: http://www.amazon.com/Protective-Case-Enclosure-Tran...

Re: Backpower Protection?

Sure, buy a powered USB hub that does not backfeed. Like this one that I am using, that has a special uplink port for data only: http://plugable.com/products/USB2-HUB-AG7 But I am more or less being facetious, as I suspect what you meant was a fix for an existing hub that someone might already have.

Re: Raspbian rapidly jumping between desktops

Perhaps you have the additional issue of a flaky scroll button or th...

I would never even attempt to compare the pi to a desktop computer. It is so slow that I would wind up smashing it with a hammer if I had to use it every day, even for the most basic tasks. Even my ancient XP computer blows it away, never mind my fairly modern desktop with a quad 2.8 GHz hyper-threa...
