Hi, I have been trying to recreate the PiBuster game described in 'Raspberry Pi for Dummies' and have copied the code exactly out of the book but I keep getting this error: "IndexError: list index out of range" when I run it. If anyone can throw some light on this (or has the complete working code) I would be grateful. This is the line that it refers to (highlighted in bold) which is very near to the end of the code: ballx+=ballxdir # This code changes the direction if map[bally-1][ballx-1]==0: # of the ball depending bally+=ballydir # on what it hits.

I have been running an after school Raspberry Pi club for Y5 & Y6 children - using 5 devices, 2 children per device. I have fitted Pibrellas to all of them and we have been coding things in Python like traffic lights, pelican crossing etc.

Ok thanks guys, I'll try these out. Cheers.

Thanks, I'll take a look at this.

The problem with Wordpad is its ok if they're just doing a bit of typing but if its project work etc, with pictures and wordart its not really up to it.

Hi Does anyone know if there is a way of disabling spelling, punctuation and grammar in Word etc? Some teachers have asked that it be turned off as kids are just using it rather than learning the proper way. Is it likely that I would have to turn it off across the whole network? Office 2013 is installed on all PCs thro' group policy. Anyone had experience of this?

I will try another cable but it would still have to go thro' the HDMI - VGA convertor as the projector is only VGA.

Ah, no, if I disconnect the PC signal the wobble goes away

Yes I always use 1024 x 768 as the resolution so it can't be that

The signal is HDMI coming from the PC thro' a convertor to VGA to the projector.

Its the image, the board is mounted on a solid wall. The image wobbled continuously throughout the lesson.

Thanks, I'll check it out.

Hi, I checked that and its tight

Hi, one of our projectors, an Epson EB-X11 has recently started suffering from image wobble. It doesn't seem to be related to the ceiling mount as there is no one above and even if I hold it still it still happens. IS this perhaps a sign of something in the projector failing? Has anyone experienced this?

I am getting somewhere now with Apple Support. I need to contact one of the 3 resellers Apple have in this country (none of which we bought from). I'll see where it goes from there.

Thanks, I'll give that a go.

No it still gives the same result. The link you give takes me to: Then sign in and get: Click on 'Get started' and get: Sign in again and get: And finally:

Yes tried Safari now and still the same result.

I first tried it on Chrome then IE 11.

Yes I did.

When ever I try to use the volume purchasing (after signing in) I see the message "This Apple ID has not yet been used with the Volume Purchase Program" then click on "Continue" I get "an unknown error has occurred". Anyone else had this? Its driving me nuts!

The only bit I can't get to work is the last bit: sudo pip install pibrella. sudo apt-get -o Acquire::http:proxy="http://proxyurlport" update sudo apt-get -o Acquire::http:proxy="http://proxyurlport" upgrade sudo apt-get -o Acquire::http:proxy="http://proxyurlport" install python-pip all work ok.

Thanks all, I found this on another post in the end which worked: sudo apt-get -o Acquire::http::proxy="http://proxyurl:port" update

Hi Thanks for your reply but when I type this at the command prompt I get this: bash: Acquire::http::proxy command not found (the 'p' of proxy keeps turning into a smiley in my post....Grrr)
