Seeeduino Stalker as automotive data logger

Hi all, looking at taking on a new project, I have no experience of using arduino's or electronics, but I am a computer programmer by trade. Im looking to build an automotive data logger for use on my Dragster. My thought is that I can use the seeeduino stalker to simply capture the sensor data and write it to sd storage as a comma seperated file. Ideally I would like to capture data as often as possible, and realistically I am aiming for 100 hz for between 5 and 8 sensors, which dependant on data length should be possible? I am aiming to record 1 or 2 K type thermocouple exhaust temperature sensors (max 2000 degree's F), engine RPM (using coil, max 7500 RPM), propshaft RPM (using hall effect sensor - max 7500 rpm), an on / off reading from my transbrake switch and possibly a throttle position sensor (yet to be determined).

Does this seem possible? Can anyone give me any hints / tips for recording such data? Data could be saved as a raw value and converted by software afterwards where needed. Many thanks in advance. Dave

Your project certainly sounds interesting, the only issue that I can see is that the arduino only runs at 8-16mhz, polling a sensor that will trigger for less than a millisecond will be an issue unless you build a shift register based counting mechanism and used the output that that gave you as a reference for each RPM sensor. Temperature can be used easily, as can throttle position and a simple on/off from the ?trans brake?. This unit is basically a device that you can put onto your Arduino serial port and every bit of data you send to it will be saved to an SD card. It would seem to be something along the lines of what you need. As far as the RPM counter goes, I have no idea, some people seem to have done it successfully using just an arduino, I have not ever attempted it at all.

I think I could use an LM2917 to convert frequency to voltage (I still need to research it)

Ok, seems you have done some good homework there, that looks like just the device you want, if you can get the output voltage to be between 0 and +5 volts you can attach it directly to an analog pin on the arduino and grab readings at any time. your only issue is you might need an arduino Mega to get enough analog pins to deal with two rpm inputs, one throttle position, and three temperature probes.
