I do not own a Atom yet, but I am wondering if it can do what I want before I go to the expense of buying one. I looked back through the messages here and didn't see anything like this.

I would like to build a data acquisition system for my RC truck. Sort of a real time dyno. I am looking to monitor the following: battery voltage, current draw, battery temperature, motor temperature and rpm in the beginning. Then maybe later add on G forces, servo positions and who knows what else if the first part would work.

I figure I only need to collect data 4 times a second for 6 minutes. Figuring 5 sets of data 4 times a second for 6 minutes means 7200 data points. Once done the data could be transferred to a PC of plotting.

So I guess what I want to know is if this is possible with the Atom? Open to ideas, recommendations and input.

The first 4 battery voltage, current draw, battery temperature, motor temperature could easily be done using the A/D of the ATOM , the rpm could be done using the count command you just need some way of getting pulses from the motor which could easily be done from the output of your gear box then multiply by the gear ratio to get the motor rpm.
If you use Accelerometers with duty cycle output the are very easy to use just use the pulsing command to measure the low and the hi of the input signal and you can determine the duty cycle from that. If you need more data storage you can easily add an eeprom for additional data storage.
