The way I see it, with a vacuum gauge, and a ammeter (at the moment I have volt gauge in there, but I'm going to change it) you would need most of the parts out of the gauges anyway with the pocket pc. As in you can't just plug a vacuum pipe into the pocket pc (not that I know of anyhow

)
And there is plenty of space there, so why not have analog gauges? I like them too. But, if you want to do this too, be my guessed with pocketpc gauges. And let me know how it goes, I'm always interested in things like that.
Smoov, you indicating I can find programmers to do this for me on google, or actual programs that do this? I'm not interested enough to bother looking on google actually. But if anyone finds anything, post it here for others to see please.
