rad400 posted:Ringy? Please explain? These are suppose to be square waves, but in all of the pictures that we have all shown, none of them are square. Is the so call "square wave" suppose to look as we have shown them in the photos or is there a lot of distortion being introduced some where in the circuit?

It's a square wave plus an e^(yt) x cos(wt) term from all the wire inductance like the last part of the tutorial talks about. The amplitude is fine and if johnf tightened up the loops in the wire it's be a square.
