Wouldn't mind owning one myself actually, but really would want to print larger objects than 20x20x10cm I've an idea for a case not so much like a QL but more an Acorn Atom, with an external slot for a standard sized bread-board PCB with an edge connector so as to easily build and slot in hardware projects without opening the case. The only problem being that I need someone with knowledge of (single-sided) PCB design, power regulation circuitry and 3D CAD. Oh, and someone with a 3D printer and/or injection moulding facilities if I wanted to try to market the kit. Other than those skills I'm fine! ;-) Steve ___ QL-Users Mailing List http://www.q-v-d.demon.co.uk/smsqe.htm

we are doing a case variant which comes with a 15cm ribbon cable and connector everything you need for HW hacking ;) Should be on EBAY soon but if you are interested shout me directly john Alexander --- On Tue, 3/7/12, Dave Park plasticu...@gmail.com wrote: From: Dave Park plasticu...@gmail.com Subject: Re: [Ql-Users] Rasberry Pi arrived To: ql-us...@q-v-d.com Date: Tuesday, 3 July, 2012, 21:52 On Tue, Jul 3, 2012 at 8:15 AM, Tony Firshman t...@firshman.co.uk wrote: Yes in theory at 700ma plus usb devices, but http://www.raspberrypi.org/phpBB3/viewtopic.php?f=63t=6050 finds 210ma max.

According to Eben the Nokia N900 display should work but I don't think there's any drivers as of yet.

Login as raspberry user I think root is disabled. Also load the latest Image then do an apt-get update on it as it cleans up a load of stuff.
