Why is this thread locked? As I said, there is an easy way to do this. No one seemed to recognize that the output waveform (see below) is the derivative of the input. A differentiator is very simple. I have posted one below, followed by a logic level translator (the transistor). The value of the capacitor is selected depending on the slew rate of the input.
C1=200nF/Vpp, where Vpp is the peak to peak amplitude of the triangle wave. This will yield +/-2V at the output of the op amp, which is used to switch the transistor.
