TL072 dual op amp rail splitter and alternating square wave generator circuit step by step build

TL061 op amp alternating square wave generator circuit voltage measurements video using 2 single op amp components to build the same circuit in this video. TL061 op amp alternating square wave generator prototype circuit powered by UA741 741 rail splitter video where I step by step build this circuit but using 2 single op amps instead of the dual op amp used in this video.
