For a :

The output is roughly 50% duty cycle only when R1 = R2 (in standard circuit). Many calculators don’t show or calculate duty cycle. period_e = hc14_oscillator(r

Use a fixed C and a trimmer potentiometer for R. method="exact") print(f"Exact (5V): freq_e:.2f Hz

"It shouldn't be this hard," Lucas sighed. "The math says one thing, the scope says another. The tolerance is all over the place."
