    Hi all,

    For pat of a college project building a closed loop feedback system on a small 12V conveyor.

    For the input i was going to connect a small metalic wheel to the motor of the conveyor, and use a proxy but this only gives a DC outout. Where the 8 pin LM2917 needs an AC input. The only reason i was going to use this proxy is because i happened to find one at work.

    Is there anyway to make this work, or a cheap / easy alterntive?

    the circuit im going to use is in page 8 of this datasheet:

    Any help is much appriciated :)

    Thanks lee

    Can you post your schematic of what you intend to do?
