Through the years I have identified recurring rules that underly most of my "bugs", "failures", "mishaps" and other blunders.
Rule 1 : If you connect it to the power supply, it works better.
Rule 2 If you connect it with the right polarity, it works even better.
You could argue "it goes without saying" but it goes better when you say it ;-)
Please comment and contribute with your own "golden rules" :-D

Just a friendly reminder.

Playing with Fasltad's circuitjs to create a slightly better hysteresis circuit than the default circuit. It's crazy because changing any value affects the rest of the circuit.
The main difference is the feedback resistor, and a better choice of resistor values.
I tried to reduce the current draw and increase the hysteresis, which keeping convenient resistor values and decent logic levels (at least the low level is < Vbe at 3.3V).
That's if for today :-)
