First, Ugghhh! I was trying to reply earlier today on my phone and all I was having was problems. OK, rant over!

I think it should be called the Gduino.
I wouldn't even know where to start with an Arduino. It would be good practice for when I do an automatic grill block though I don't know if it would be worth the cost of an Arduino board plus the accessories. At least with a grill block, I can see a payback, not really with a Gduino.

So I downloaded some different sensor apps on my phone this morning, just trying them out now. Holy cow!, I didn't realize my phone had so many sensors! So far, I can't really see any app that's better than another. I have noticed that I have no idea what the numbers mean (at least, I have nothing to compare them to, so I don't know how to "decode" them).
I would like to try the torque app and compare it to my UG, but I don't feel like spending the money just to try it.

Not sure how facetious you were trying to be, but I will respond with a facetious answer nonetheless... It will be pretty hard to drive with one hand, shift with the other and hold a string up in the air with my third hand! Also, I like to follow the law: don't derive and drive!

You can also use a 2d "gravity driven" inclinometer with a fore-aft accelerometer to account for motion, with a sanity check when the car is not moving. Assuming you do not spend all your time fishtailing.
Didn't know planes did that, thanks for the info. Is that one of the procedures they do when on the tarmac waiting for the tower to let them take off?
Definitely am not planning on doing too much fishtailing any time soon! (:




Can anybody help me figure out a way to do this to match the signs on the road (i.e. 7% slope ahead, etc.) I want a display with a # like this, so I can use it and compare it.

Thanks!
