Sorry for bumping an old topic.
The geekstudio site does not work anymore and it says the account was suspended and his last online activity on forum was 05.11.2010.
His shield eagle board file had a small mistake. The analog input connector was twisted in the wrong way. I fixed the mistake and improved the shield by adding another connector in parallel in order to be able to connect additional shields on top of it.
I take no credits or ownership over the files.
The files can be found here
