To do that just add a second IC and use ½ of it as an inverter and the other half as a buffer this will give two outputs that are 180 degrees out of phase with each other.
Note: One LM339 can be used in place of the two Lm393’s, as it is the quad version of the 393.
The 555 is a great little chip, with untold uses, but trying to do this with it is an exercise in learning how to tear your hear out.
THAT WAS JUST AWESOME!!
MANY THANKS!!! Mad Scientist!!
