+# Phase Shift Oscillator
+
+I just was curious if you could just chain a bunch of inverting amps to make an oscillator because you are shifting the phase by 180 at every stage. It looks like I was maybe getting some oscillations but probably just incredibly unstable. I never made this on the bread board.
