Re: Warrington Raspi Users

I live 15 miles away - don't see the advantage over this forum unless there are going to be meets - I've collected some bits and pieces that are surplus to requirements e.g. HDMI lead that could be useful to someone else - you cant swap hardware over the internet!

Re: Motion Tracking and Targeting

I would go for a tesla coil using the transformer from an old microwave - no tracking or targeting required and doubles as a security light after dark.

Re: Mobile Broadband

pants - there does not seem to be a version of wvdial for arm architecture: http://packages.debian.org/squeeze/wvdial :¬/

Thanks for the hints anyway - can use that technique to get packages without being online, so maybe no need to have my pi hooked up to the web via mobile broadband anyway :¬)

Therefore I can update the boot directory via my windows PC but can't access the modules directory using said PC. Can I do this from a usb dongle using the Pi comma...
