    hi,
    You could use a number of device options for picking off the RPM, eg: opto or hall effect etc..
    Amplify the rpm signal to a TTL level and use say PORTB.0 of the PIC to count the pulses over a given period.
    Output the rpm to LCD or RS232 port.

    Does the "dynamo" produce a DC output relative to its RPM?

    Please explain what type of "dynamo" it is, as that could just be a language translation of any number of devices. :)
