arduino pro mini face-palm.

[Horst]

That's the info I think I was really after. I had ordered an interface board from one of the Chinese eBay vendors recommend by the my sensor page. It just hasn't shown up yet though I have everything else. I'll try one of the vendors you mentioned if they have good ship times. Else, I'll just wait for the slow boat from China. 

Thanks,
Horst
