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 :-)

I tried to simulate this one but the curves are weird...
