Xterrian, if you are going to go "glass cockpit" then perhaps this will work for you. Might blow your budget though! Crossbow Gyro AI

What do you think of this Ken? Do you think I can put together something similar for less than $100. That's all they want for it, and it seems to meet all my requirements. Kayak, I just noticed that if you go to the second page of the pdf file linked to above, there is a picture of the Crossbow software running. Coincidence? I think not.

I prowled around the xbow site some more and it looks like they have a model for auto use. It also looks like you can download the software for free but I didn't try. Anyway, I'm interested in what you are doing. At one point I was going to mount an old vacuum gyro driven AI that had been decertified for flying. Not much panel space for a 3 inch gauge though. They are pretty chunky.

Another link for you of somebody doing inertial guidance using the chip you are looking at using. You could browse his code etc. IGS

Well, I've gotten my tilt sensor samples from Fredericks. They look so cool, and the circuits to use them look so simple. An oscillator to give it some AC then an anolog to digital converter to give me PWM and then into the computer as hexidecimal value. No worries about it knowing which way is up. Fredericks even sells a board for it that puts out PWM for $100. I don't need perfect accuracy, so I believe I might be able to do something cheaper. Electroken, can you recommend some basic electronics books for building oscillator circuits? I really want, "The Art of Electronics" by Horowitz and Hill, but it's way too expensive. Know where I can get a used copy cheap? Sorry Ian, I want to support authors, but for a hobby, I can't pay $70 for a book. I already spend over a thousand dollars a year on medical textbooks.

Just so those that are interestd still know I'm working on it. I've included this link to a guy that built one for his personal radio telescope. I'm still working on digesting, "The Art of Electronics", but I can only spend so much time in the bathroom.

Interesting link. $100 for only one axis. How sensitive is your device going to be to acceleration? Dip a wheel in a gully and your reading could swing off the chart unless you damp/avg it somehow.

Very cool. When I talked to you at GOX I never thought you'd try to go through with the virtual dashboard. A lot of work, but I'm sure it will be worth it in the end. I'm looking forward to seeing pics. I just bought a new computer and am thinking of trying the indash computer thing with the old one if I can fiberglass some sort of mini case. Good luck! John

But i like it Xterrian, why not rename your Xterra "KITT" and program in some AI so it will interact with you and make wisecracks as you drive.

Hey Ken,what do you think about this cicuit for my electrolytic sensors? Edited to add: I ordered samples of the LCD and ADC from Maxim. Can you help me decide which PIC I need. There are too many choices when I put in PIC16C54C with Microchip.com
