Knowing that probably not many people are going to watch stuff like that. I have to thank you for your effort. I love the fact you still cover lots of the 74 chips even tho many seem like being outdated already. But every hobbiest elektronics guy still loves them.
The CMOS version is the CD40106. I have both. You can use them to create square waves, among other things, with a resistor and capacitor, just like a 555. I think I got both chips to test circuits that would a create an adjustable 0-100% duty cycle square wave as an input to a DC motor driver. I don't remember if I succeeded in building one.
The 40106 is one of my favorite chips ever. It's so useful and versatile but especially good for creating square wave signals for clocking other chips and creating 6 different audio signals for DIY synth stuff with no more than a pot and a capacitor. Just last week I was messing with a circuit that used a 40106 and was wondering how big the hysteresis range is and how closely a Spice simulation matches real life. The simulation was only 0.05V off from the breadboarded one. The hysteresis range is 0.825V in a 5V circuit with a 40106. ibb.co/7kfVHBJ
It's actually fairly easy, just following the block diagram on the wikipedia page. You just need some op amps and basic components. Making a homemade op amp, now that is a whole different ballgame.

Greetings from North Africa (Algeria)
great explanation, thank you.
Such a great and practical explanation. Thank you for sharing 👍

I love your videos always very informative thank you very much will share your channel as fa as i can
i like explanation a boss change papers !!!very creative . thanks from brazil !sugestion: remake a pratical video i can´t see the voltage change.
did i hear you right when you said you will show us how to build our own 555???? COZ THAT WOULD BE CLASS!!!
