Optical Bench REDUX: Digital Switching can have Analog Functions!

<< < (70/71) > >>

Please forgive, some of these preliminary numbers aren't trustworthy yet.
   Paring down to FIVE individual fibers, out of the 1000 fiber bundle, I've gotten it to go through change of 0.008 volts (8 milliVolts), dark, changing to 0.030 (30 millivolts), illuminated, with 5 strands.

   However, I need to solidify things, on the table here, as my light baffle has to securely hold the 5 little optical fibers, while simultaneously blocking and holding the rest of the bundle secure.
But, it looks like the electronic aspects, of detecting that little portion of light is easy, if feeble.  Need to set up to read that photocell current as well, but seems a sensitive FET can easily handle the (30 mV), even if total power isn't much.
Tomorrow, better test jig...

   Wanted to briefly show, an older concept, of using the lawn lights as digital switches, having less layout rules, as it's light beam paths that carry signals, where usual electronics has...wirrs.
(That's broken slang, for 'Wires').
I noticed right away, that such 'amorphous' gate interplay was causing a latching ability, similar to cross-connected gates.

(Electronics would simply run traces wherever needed, regardless of any requirement (in optical) for running 'straight line' signal paths.

So also, while viewing the last two Garden Light layout arrangements it should be clarified that the 'two' inputs featured, in the NOR gate illustrations, the meaning is really 'one or more' inputs, depending on where each light beam is traveling.  Two inputs shows, how the little gates can be used as '2 input NOR' logic.
In an 'accidental' bio-system layout, that random orientation would be, could be, massive numbers, like hundreds of tiny cells, waiting for evolutionary selection to act.  Eventually, a complex system could emerge, from the disorganized jumble presented here.

The latter diagram shows a nicely reorganized and more clearly discernable structure...implementing classic 'SR' FlipFlop.

Maybe not obvious, but in context of popular neuro-network analog qualities, you would have attenuation (i.e. adjusting analog input weights), caused or controlled through device spacing and optical beam angles.
Of course this sort of free-space in 3-D layout wouldn't be used in some of the integrated devices...they used optical fibers and conduits, waveguides, rather than free space setups.
