    I have built a simple sine to square wave converter in LT Spice. Need some of you more experienced guru's to have a look, the output seems to be doing what I want.

    Its for an automotive project, to be more precise the speedo requires a 0-10v square wave, I only have a VR in the gearbox producing a 0.2-36v sine wave, frequency & voltage increase with speed. Supply voltage is 12-14v.

    Anyway here is the circuit.


    Thanks for looking and appreciate any feedback. I'm green when it comes to electronics.

    This is a piece of cake for electronics nerds, but you're on the wrong forum. We don't do automotive here. A moderator will be along soon and give you a list of forums that do automotive electronics.

    Doesn't have to just be automotive related, I just want to know if this circuit would convert a sine to square wave. Thanks anyway.
