In this weekend, I'm trying to build my old idea: RS-trigger in the "forbidden state" (when both R and S is "active" in one moment).
Like Chua's circuit (https://en.wikipedia.org/wiki/Chua's_circuit), my circuit is very simple, but fully digital (online simulation (https://www.falstad.com/circuit/circuitjs.html?ctz=CQAgjAHCAMB00OmArANgEzJAZgu2A7BsnmACzYCcl0qZIy0DDTyApgLRhgBQKYIVAhxFBZJtlED0zZH2QChTMuLHLV02fIHJkM8VGSV90KJqxz+akAcERlp8CBkWeAd2uTU18U2jufYSUbMG9-D2CyUMFhChlwmIkIekjhBNSmOmVo9NUo7yybVXTYskNjIqgEo30yhgrbaobHGpxUKoDW7HbEto6PXX1owZs0GE69UYL7KfGImbIx9ocOgCcGSaoXTZ6mMER-ACUNmW7WTe6YK9UsPxhYOQHNipHfOZO+j7P31+FkFRsaR4AGcGOgHKwAW89iAAGYAQwANsC2DwAOZgiGYmwzPx8Oh2CRCEAEaD0b4CKpXW7Uq5MBHItjvZZtTKqb65IlsiSifwAZRJkzI6HoBHQUGF9AkcKRKKulACYolECghTK-R8Kp8xR46G4gv0IpJDSNeyY9mEvHE2BJxK2IBVErGEmgAH0wK63WB0OgaK7kJ74AgPVx3TwgA) for draft)!
The variable resistor works as a delay line for inputs R and S to help the circuit find balance (when the switch is on, the trigger must settle into one of the two stable states).
Like my previous researching (link (https://overunitymachines.com/index.php?msg=2226)), this circuit now is very-very simple and based on a single SN7400 IC.
Good ICs for this purpose is SN74LS279, SN7474 or SN7472.
But at this moment, I am build the circuit using only the SN7400.
P.S.: The main idea: Detection of torsion fields, solar neutrinos, or black hole collapses.:))

Hi Alikberov,
looks neat. How are you going to test it? Do you have means of producing black hole collapses at will? ;D
Surely beats pushing buttered slices of bread off of a table and measuring if it always falls on the buttered side :))
Ok now that the jokes are out of the way - Are you doing experiments with torsion fields then? Are you able to influence it with your mind? :)
Well, respect for interesting!
As first - I have RADIO-86RK (https://en.wikipedia.org/wiki/Radio-86RK) (near analogue - TRS-80 (https://en.wikipedia.org/wiki/TRS-80)) with video-out based on i8275 (https://www.emuverse.ru/downloads/datasheets/peripherals/display/8275/8275.pdf).
The i8275 have one input LPEN (Light Pen) and lot outputs (GPA, RVV, HLGT).
In the basic model of that PC is haven't color RGB-out and all pins is free for optional use.
In this case, I can turn on/off my RS-trigger by signal from i8275 with full programmally control, when this trigger must to be activated: I can paint needed region of screen with signal from this "detector".
Then I can to do a "smart RS-Monitor".
But main problem - is too highly frequency (25 MHz as Composite-In for CRT-TV - is very high)!
(Using the counters, like SN7493 - is bad way (any counters is smooth-up the noised "real RS-picture").
As second - So, in 2004 I haved tiny OOBE (https://en.wikipedia.org/wiki/Out-of-body_experience) and reads trilogy by Robert Monroe (https://en.wikipedia.org/wiki/Robert_Monroe).
Late - Torsion Fields by Shipov-Akimov (https://en.wikipedia.org/wiki/Torsion_field_(pseudoscience)) and Axion Fields by Shpilman (https://spinfield.narod.ru/ALMANACH/N1_98/properties.htm).
As short - Yes, I have few extras in this case.
But I can't understand the classical radioelectronic - digital only! :(
Then, this RS-detector - is "my digital word" in whole of that all. ;D
Today I made a second experiment using a neodymium magnet.
At first there was a stable sinus without reaction to a magnetic field.
But, when some knot of solder broke out, I found the "Hall effect" and the frequency was filled with curious noise.
P.S.: I need to remake on a layout against hinged air montage and move to another good elements of TTL, like SN7475.
More variant - digital optocouplers, like 6N137 (https://docs.rs-online.com/9a25/0900766b80de4953.pdf).
