modified another circuit
src. :: http://wilf.solarbotics.net/Altbeam/Altbeam_files/Altbeam.html (seek text tlc -- for TLC27L2)
mod. :: didn't like quite a lot of things about it's operation so . . . it auto optimized itself to ↓ that ↓
the Spice shows a stable error free graph -- which i quite doubt would be that in real . . . but it's an add up concept to the few long interval timers out there . . .

some xx555 timer tests
crystalless oscillator / attempt to discriminate the intervals (initialized by pin-4 , R2 , C4)
-- the messy circuit is remnant for testing out several pulsed feed options -- this one seems to produce equal (14-tick) on cycles ???
"inversed rails" variant (an attempt to avoid initialization of the retriggerable monostable -- it still requires initialization -- by pin-2 , R11 , C3 -- this time)
