Bill;
After getting somewhat lost in Hawaii, Joline and I just joined the tech revolution by trading in our old cellphones for Motorola Droid Maxx smart phones. I had not realized when we bought them just how versatile they are.
For example, a Droid Maxx has a built-in 3-axis accelerometer, a 3-axis gyroscope, a barometric sensor, a magnetometer, a light sensor, and a good GPS. It even has a cell phone in there somewhere
There are a few apps available that allow the phone to log the data and export it to a spreadsheet. As an experiment, I put the phone on the center console of my truck and recorded the x,y,z accelerometer data while I drove into town; it plotted a nice graph of the drive data. At the same time I had it record GPS data showing the track superimposed on a map, max & min speed, distance travelled, and also plotted the speed & altitude vs time.
There is also an app that provides a nice big digital GPS speedometer readout. If you desire, it turns the display upside down so you can place it on your dash-- the display reflects off the windshield as a head-up display.
I think this is not a substitute for a full-fledged data acq system but what it does, it does very well!
