	Thanks Chris. Yeah I more or less know basically what I need to do, I'm just 
not sure about specifics, like what kind of electronic pressure regulators 
are out there and how they can be controlled. From what Craig was saying on 
the viperpit forums, it sounds like a simple variable voltage is all that's 
needed on certain units. This I can do. :)
	I could probably learn assembly or something for programming microprocessors 
(I think that's what you are referring to?), but with Phidgets, I don't see 
the need for it right now. That's something I'll probably play with in the 
future though, the idea of being able to take a BASIC stamp or whatever, some 
simple electronic components, and make all sorts of interfaces, really 
appeals to me. It's just a matter of the initial learning curve..figuring out 
what I need, putting it all together, learning a new language. Electronics 
would be my weakness here, I'm not very knowledgeable in this department. But 
no worries, for now I'm having fun with Python and Phidgets. :) And it looks 
like Phidgets can effectively handle just about everything I have planned for 
my pit.
