but I am using an RC oscillator. an extremely low-power one, on the chip, that's already been trimmed to ±1% at room temperature. reproducibility is a nice touch. so too is smol. so also is non-calibration especially when the time to be tested is particularly long
unless I missed a post, anon never put a number to "about" 40 minutes nor specified what sort of process he was enabling (heating, cooling, blowing, lighting, stirring, opening, closing)

Digi-Key prices as of a few minutes ago: about $0.49 for the 4536 alone in singles, not counting support components. about $0.43 for the PIC10F200 in singles. other micros with internal calibrated oscillators can be cheaper still. chinkbay and/or quantities can vary the balance. 100n bypass caps are assumed free

agreed. all that said, chained 555s is next-level sheepposting and thanks for the (You)

do Cypress PSoCs count? waiting for some checks to clear so I can pick up the PSOC 5LP programming tool/dev board
