Subject:RE: [DUG]: Sampling sound
I am wanting to read spark plug pulses so i can calculate rpm (and then add
in accelration measured by a g sensor).
The easiest way of doing this is via the microphone jack. Then I can find
the peaks and do something with the information
celeration. By doing it this way you won't need the
Analogue Input board.

Alternatively the acceleration can be measured by "tapping" the
speedometer's pulses by sticking a hall generator at the back
of it (right
next to the cable going in) As you may know it rotates a
magnet to displace
the needle. This hall generator (connected up
Thanks for all your suggestions. A few more details would probably help.
I have a G sensor with serial input. I can read this quite easily. This
gives me x and y acceleration of the vehicle which can then be integrated to
give speed and distance (approximately). I have a working program
