Sharing some project planning phase: A (digital) ELECTRO-MECHANICAL Network
RJSV:
For the Sq wave: Diagram shows 'T3' at bottom; that's the output you want, timed to 340 mSeconds.
Notice the waveforms T1, and T2 finish and then just 'hold' there. Each separate timer can do that, for a cascade that enables the next component, without additional explicit switching.
Don't be fooled, by thinking a time interval is over, when the timer reaches 'Sat.', as there is still a short bit of work, (and rise times), before effective end of this little cycle, and start of next.
Notice, also, turn-off IS faster here, at 90 mSec, than the bigger swing 250 mSec for the 'assertive' contact switch end-field.

this came to mind, the 'no go' zones of these kind of contraptions are bound to be interesting. Then you start thinking about flex of the chassis to allow the gears to some how walk over each other or something so they do not break teeth when it has a aneurysm. So the shafts in the gear box and the gear box walls are all spring mounted and it yields and has a (undefined) spasm instead of breaking bones. That sounds like it belongs on a battlemech (from the battle tech universe, how do you make a bipedal tank keep lumbering after it gets hit by a rail gun?). that might be applicable to walking proteins too, since atomic bonds are stiff but often described with springs.
RJSV:
Here is diagram, probably still imperfect, but to show the 'cascade' sequence, at the end everything's streaming out...
But like before, the good Output you want is from 'T6'
and there are some special details, keeping rotary direction proper, for the negative half, of Square Wave.
E.O.C. (see right side of diagram), means 'End of Cycle' and that would start up a process to 'restore' the various toggle levers, for next plus / minus cycle.
RJSV:
This looking, 7 gears -switches, course they're TIMERS, and do special jobs, like issue overflow / underflow status...(like some 1982 z-80 CTC beast).
And so being TEST GEAR (no real PUN), that's no sweat build.
The arrangement sends out Clockwise, 500 mSec, then 500 rest stationary time.
That second half is simply blank timing, as the zero part of Square waveform.
Same for the CCW or counter-clockwise Output, you get 500 milliseconds on the CCW labeled Output, then 500 of stationary rest.
Notice it's two fragments of a SQUARE WAVE, needing a mix.
RJSV:
Coppercone2, I'm going ta need you on that...WTF ???
DIVIDE BY ZERO ? ...HUH ?
...what happens, if I press 'PLAY' ?
Will it: PLAY another video ?
...maybe it will 'PLAY that video...'...
Huh, ?...
