Well, no problem blst ...
... I´m sure that those of us who know how to read electronic diagrams - it´s quite clear. But I´d guess that even 1000000 words aren´t enough if you try to explain it to a guy who knows nothing about this stuff. Keep up with the good work!
I´m impressed about your achievements. All you need now is proper digital control system for the cars.
