Is my OBBLOG

Ignoring the equivalences of the Karnaugh table, OBBLOG contains all the possible logic gates with two inputs and one output.

This is the partial living OBBLOG Truth Table:

For to build a operating toy, I added forks, crossings at different levels and bit visualizers. (Similar to a light bulb)

However, the toy did not have flip-flops, so you could not make a numbers counter, although small binary calculators 1 to 16 bits.

The toy allows to build little and simple animated toys:

Or more complex constructions:

Binary Tree:

But from the initial basic logic gates, I discovered that it was possible to build a flip-flop:

(And consequently a counter of binary numbers):

(The obblog allows a closed loop that continues

to circulate indefinitely if not obstructed)

(without flip-flops)

I posted all this, because yesterday I found similar artifacts along the history of computing:

The article published in Scientific American the December of 1964:

Fluid logic devices, all based in the Coanda effect:

And the conference from Manu Prakash,

The manu Prakash Thesis: (About "microfluidic bubble logic"), and inside this beautiful Truth table about logic gates and its equivalents in transistors, valves, electrical devices, and fluidics:

Some examples of projected fluidic devices:

(from Prakash thesis)

Integrated fluidic logic gates with a schematic integrated control circuit

The main patents about fluidics, come from the sixties:

(from wikipedia)

And schema about Coanda effect from Popular Science (Jun 1967 Pag 118) :

And the: Fluidics: Basic components and applications

By: James W. Joyce (1977; Unclassified: 1983):

And from the conference:

APPLIED HYDRAULICS AND PNEUMATICS U5MEA23 Prepared by Mr. Jayavelu.S & Mr. Shri Harish Assistant Professor, Mechanical. http://slideplayer.com/slide/5675986/

I would like to see these companions of my program, running.

Anyway, everybody can see them inside the Bowles products:

And inside of the Theranos patented devices: (Lab-on-a-chip)
