practical 'ow 'er logic test

needed a 1:10 duty oscillator - so i revised/-studied/-tested some trivial generator types . . . the schmitt-inverter showed up a fairly good properties for design target (power levels indication) - more over the inverter passed the basic logic test without any modifications (this is like something extraordinary)

and the schmitt+inverter itself with SB captured 2-ch scope diagram through 1nF+3.6kΩ decoupler-probes

if you remove the 15pF capacitor and add input diode pairs you'll have a set of 7µA NAND-s
