Any question answered...

raspberry pi, perfect for the job surely?

also, why did tester change organist to onanist in the plumbed in organ debacle up there^? I didn't get the joke, if it was one, unless it was a subtle bit of calling someone a wanker on the internet, which I did get, but will refer to my previous comments on the role of onan in the bible.

I assumed it was some classic tester 'humour'...
