thats an inverting schmitt trigger, but the final inverting transistor stage is skipped and the output is taken from the first stage. Thats clever and its also working in simulation and with a very good chance also in real. Its simple in sense of number of components but im afraid its not simple in understanding how it works, most users will see it as not simple and need an detailed explanation how it works. So the word "simple" in headline is as mostly misleading. Anyway, its a nice circuit, i like it 👍

Oh, nice! :D I never quite got the hang of this type of Schmitt trigger. I'll have to study it.

@hurz: I had this problem with an operating system I wanted to understand: Plan 9 from Bell Labs. Very little code, but very confusing! A friend who understood it better than me said, "You have to be a genius to understand the simplicity!" :D

this schmitt trigger with the trick to take to output from the first transistor is like a 74ls14 you get 6 of them. im not a genius, try it but if its related to something propritary inside this OS i dont have a change without the help of google. Test me 😁
