I have a motor home without a tachometer, some salvaged electret microphone elements, and an app for my Nexus phone that "listens" to the sound the motor and tells me the RPM of the engine. I'm thinking that as I roll down the highway, there will be too much noise in cab for it to work and want to put a pickup near the motor, but I'm don't know how to feed the signal to the phone.
Anyone know how to do this?
Thanks,
Jeff
