Sharing some project planning phase: A (digital) ELECTRO-MECHANICAL Network

<< < (28/39) > >>

RJSV:
   You get a TON of diverse ideas, using that switch with the second, logic follower layer up top.  Several ideas, at once, can pop up; (if you are enthused), including a very 'traditional' looking 'Edge Triggered' pulse 'circuit'.
   In photo, the diagram has a drive (rotary) signal arrives to the 'D2' gear input.  Not shown is an additional connection option: By connecting the switch motor driver to the switched output, (D1), you get an interrupted impulse to the motor, that will start to dis-engage the whole switch (toggle lever).
That's one layout method. Another, places that motor input to the basic circuit input, this the motor keeps running, strong, even after pulling the reader portion free of any drive input.  That's going to produce a classic RISING EDGE TRIGGER.

RJSV:
This photo, features the latest shift, from schematic and (endless seeming) diagrams, to a test bed, for getting some timing info.

   Landlord is Elec Tech / Engineer with many nice items, like the TEKTRONIX old school SCOPE.

RJSV:
   Using the first test bed, I want to try out some of the many assumptions and cautions, (mostly concerned about parasitic signal feeds).
   Probably try a toy electric motor, as a generator of some electrical output, for triggering that '465 scope.
I figure, roughly, a motor shaft spinning at 30 revs per second, that's going to be 1 milli-Second per gear TOOTH, for 30 tooth nylon gear.
I have used the light metal guitar string, for various springy contacts, so that is another option, for generating a little pulse, for diagnostic uses, in the LAB.  (We use a Lab with 'car storage' option, and fresh air).

coppercone2:
as a side note, did anyone start researching spintronics after looking at all these pictures... just for namesake alone?

Something kinda makes me feel like eventually someone is gonna figure out how to use monoatomic? hydrogen as a gear

RJSV:
   Here is a pretty wild example, using commonplace analog concepts...(and YES, you can squeeze some analog, even from 'digital' switches).
   Using your custom 'C' channel, suppose you have a moveable 'STOP', that can be adjusted, in some separate action / components.
   Now, that picture shows, the temporary STOP is now at 48 degrees, travel from zero. Course, you lose any right side gear function, as that requires full travel, to insert gear teeth, of moving TIP rotor.
   You can arrange, for PULSE duration match, you would have a 'PROXY', that's just a useless looking, no output switch, that provides tracking info, regarding being in step with another gear layout; that being in the next box, or wherever.
   But back to function: The arrangement is to run the two gear trains at same time, and cause any lingering output, in the compare, to be 'ERROR', for feedback.
AHH: but not feedback to gear train run, but to cause the slight adjust, of moveable stop.
That way you can issue repeatable impulses, even though the actual components are transient involved, or, said another way: The process, for a single time interval, is DESTRUCTIVE, in that you cannot repeat, without an 'image' source somewhere. That's done by that moveable stop, that does not change, except by another, separate action.
