Triangle Signal Generator  -  A Discover Circuits visitor needed a variable low frequency triangle signal generator, which would produce a full 5 volts peak to peak signal using a 5v supply.  I suggested the circuit below.  It uses three rail to rail op amps (2 LMC6484 dual op amp packages) .  The first circuit produces a clean 2.5v reference voltage.  The second is configured as a classic multivibrator oscillator . . .
