Actually they can, it just takes a more expensive digital scope to do it. I'm sure the higher end Rigol scopes can do it. My modern R&S scopes have no problem displaying waveforms like this in XY mode. Being able to do it just comes at a cost to your piggy bank.
Absolutely. No issues with Nyquist rate and sampling depth. It's all about the visual experience. As art. Ironically, my cheap OWON 2 x 70 MHz handheld scope has an amazing X-Y presentation compared to my Rigol MSO5354. But the best is of course my old Iwatsu SS-5702. For precision measurements, of course modern DSO's are better.
Is there a way to put just the chua diode part on a curve tracer to see the negative resistance curve? BTW would also like to see the channels in standard time-domain waveforms. WIth X and Y side by side, can you tell when it 'flips' to the attractor on the other side? What is the approximate frequency of the generated signals?
It sure would be cool if you'd mention what supply voltages you were using. I guess I'll use +/- 12 VDC because that's what I happen to have available. I'm building mine right now. It's almost done, except I managed to put the TL084 chip in upside down. So, reworking it now. Wish me luck!
Cool scope patterns! You are go for trans-lunar injection burn... because the double swirl somewhat reminds me of the Apollo and Artemis mission trajectories.
Well blow me down! It freak'n works! Wonderfu! How gratifying is that? I haven't seen that amazing pattern since reading 'Chaos, Making a New Science' by James Gleick back in 1988. I dusted my book off and I'm going to re-read it. So here is what a electronic hobbyist like myself has to go through to get your little board to work. First try to get a complete schematic by taking a screen shot off of your video and download your BoM. Order parts from Mouser. Find out I ordered the wrong size TL084. Order again. Solder it in the wrong way. Pull out my AliExpress hot air reworking station and resolder it back in place correctly. Guess at what supply voltage I should apply. Fire up my vintage Tektronix analog scope. Loud pop, lots of smoke coming out the back (no, I didn't short the ground to mains). Hopefully just a worn out tantalum or electrolytic capacitor. Maybe I'll be able to repair it. I really liked that scope. Resort to an old Sencore SC61 TV repair oscilloscope that someone gave me and hope it still works. Well it does still work and so does your brilliant circuit! Next project up is your previous Lorenz (a.k.a. 'strange attractor') generator circuit. I'm wondering if the two discount surplus 'refurbished' AD633's that I found online will be up to the task? We shall soon see.
But I already bought a multiplier! (Of course it can do a variety of useful things.) However, this is a cool circuit and I have a pile of quad op-amps. :)
That's a very nice minimalistic implementation of a Lorenz attractor circuit, nice job and great channel. It would be interesting to hear what it sounds like controlling a couple of VCOs. What other applications would it be good for? Possibly a dual-output random number generator. Two unrelated video suggestions: #1-how about a video on using source-to-source NMOS FETs to make a low-loss DC switch? #2-I own an Imsai with a Z80 CPU and it was always very prone to crashing until I isolated all of the front-panel LEDs from the bus lines using a bunch of 74LS240 (I think) buffers. The buffers need to be added to the address and data busses as well as the various bus control signals. Those LEDs really draw down the signal levels on the bus.
Someone says it can’t be replicated on a digital scope but it works on my Rigol and even on my owon handheld scope. And I build it on double sided copper clad fr4 with milled traces.
Really does look better on the analog scope I swear I mentioned a chua circuit in a comment here somewhere in the past but I can no longer find it. Would be interesting to compare to the lorentz you made
It looks like a collision between two galaxies is approaching. Very beautiful to see!
One of the examples where a digital scope cannot duplicate the effects visible on the old fashioned analog scope!
Actually they can, it just takes a more expensive digital scope to do it. I'm sure the higher end Rigol scopes can do it. My modern R&S scopes have no problem displaying waveforms like this in XY mode. Being able to do it just comes at a cost to your piggy bank.
Franchement les oscillos numériques c'est de la daube pour rester poli , mieux vaut cent fois un bon oscilloscope analogique !!!!

@@zibobpompon5768 100% agree, which digital have 10 M FPS?
@@zibobpompon5768 No, they all have their uses.
That's so cool. I love playing with X/Y inputs on my analog scope.
This sort of thing always looks best on an analogue 'scope.

Pleasure to be one part 🥳

dude how cool)) is it in the audio range; lets make it hear for us please. might be very interesting. best hp
The analogues definitely shines and clarity and resolution.
The digital looks like an old Commodore 64
What voltage are you operating the circuit with?
3 cheers to the good old analog cathode ray oscilloscope (CRO) 🍻
It would be fun to watch a very slow version, and also use it as a control voltage for a synthesiser!

The AD633 Lorenz circuit is also working. Hoooray! Who'd a thunk chaos would be so easy to achieive?
Wow, so it works! I'll give it a try in the breadboard.
educational with exercises! how could I resist this!
Would be interesting to _hear_ what this sounds like, maybe into a VCO.
i had similar idea ...or maybe like guitar effect ...
One of the first thoughts I had too! Got to be done!
Search Chua's circuit audio on RUclips. Part of it sounds like a car doing donuts 🤔
This was a very quick PCB.
I shall build one. Thank you ! 😊❤😊
I wonder how does it sound if you put it in audio range?
can you kindly recreate duffing , ueda, van der pol and rosseler attractors !!
find me good schematics
But I already bought a multiplier!
(Of course it can do a variety of useful things.)
However, this is a cool circuit and I have a pile of quad op-amps. :)
How about Z as intensity? I should wait to the end before commenting. Patience, Nick.

I had also buffered the LEDs and replaced the motherboard with one that had ground traces between all signals
A chaos generator :)
Looks like the chaos theory symbol
Why stop at two attractors? Make a circuit for three or more and impress your friends. :)
Reminds me of a 8 track tape
Showing your age and geekness in little words. Well done! 😎

buy them both! 😎
Did anybody hear how it sound?
nice
the digital one looks not that nice 😅
