      Does anyone know what type of a component I can use for an inductance
      sensor (kind used in like automotive timing lights) I would like to
      generate a logic pulse per voltage pulse for use in a Basic stamp
      Tachometer for use on small engines. Will se up to absol. max 10,000
      rpm's. Any body have any ideas. Otherwise does anyone have a good
      expanation of how a hall effect sensor works and if i could use it to
      send a pulse out as the magnet of the flywheel spins past the sensor.

        I think you'll find a Hall effect sensor much easier to use in the long run,
        But I've never used one, so I can't give you detail on how to use them. I'm
        sure any number of book at the local library should be able to hewlp you with
        that more reliably than I can.......       Good luck.......

          Here's a couple of simple things I did with some Allegro
          hall sensors. They make it real easy these days. The
          ones I used only have 3 pins: +5V, ground, and output.
          I don't know about max frequency, but you can follow
          the links to their site. There's linear and switching
          output types. And one is a switch that turns on when
          it sees either pole of the magnet. Free samples online.

            Hi,

            I have a circuit that tries to run a solenoid by using a reed relay
            to connect the power. The circuit+relay works fine if I try and
            connect a motor, and the solenoid works fine if I just connect it
            direct to the power source. it seems like maybe my relay is switching
            on and off really fast instead of just staying on, does this seem
            possible and could it be the problem?

            any advice appreciated,

            Mark
