I quite agree Rick. I'm sure that's the case.
Even some of us experienced in electronics are somewhat bemused by SC'c unstructured and disjointed style. And irritated by some of his sweeping generalisations.🤔
He still seems to be low on this particular learning curve himself and reporting more failure than success at the moment.
Although there is also much to be learned from "Don't try this because ..." reports.
I also believe that many are disappointed cos they thought they were going to learn how to build a simple ESC. They're not! ☹️
This rather complex circuitry is intended to provide a rudder/motor mixer function for twin screw RTR models (such as the HobbyKing Southampton/Richardson tugs) which use a single proprietary combination RX/ESC/rudder control circuit board.
(Later models now also include some electronic switches for lights and smoker on the same board. My oldie doesn't😭 Not to worry I'm upgrading it from 40MHz to 2.4 Gigs anyway.)
As far as I can decipher, in essence what SC is trying to do is to tap the control outputs to the motors and rudder, and use them to recreate the input signals from the RX which created those outputs in the first place!!🤕
Then apply those to his own circuit which splits the original single ESC control output into two. These he will then apply to the two motors in a mix ratio governed by the rudder commands.
Probably a rather limited market so to speak
I think you'd be better off continuing your experiments in private, documenting everything as you go. In a Word document and with close up photographs of each construction step and simple explanations of the functions of each new circuit stage and new components as introduced and why it is there.
Then when you have it up and running you can edit and tidy up your Word doc and post it chapter-wise as a cohesive structured 'How to' that will be easier for novices to follow.
This would also give you time to tidy up the breadboard experimental layouts to make a more compact easily reproducible layout.
Word documents can be posted on this site no problem. Converting to pdf is even better.
