	~~====but actually in Cascada 2.0====~~
	:The bottom sensor comparator(out1) is wired to the D and through a NOT gate to set. out1 is HI when dry and set is LO forcing !Q HI which only happens when the water level is below the low sensor. The HI turns the pump on.

	~~if reset is always HI (proposed pcb hack)~~

	~~when completely dry, out1 HI D2 ON~~
	~~:set would be LO D would be HI(doesn't matter) CLK would be LO, !Q wouldand pump would be ON~~
	~~once low sensor is covered out1 LO D2 OFF, (pump should stay ON)~~
	~~:set would be HI, rest HI, D would be LO, CLK would be LO, no change !Q stays LO so ON (now reset is actually LO oops)~~
	~~once water reaches upper sensor ^ D3 ON~~
	~~:set would be HI, reset HI, CLK ^ so D LO would be Q so !Q would be HI and pum would go OFF~~
	~~once water falls below upper sensor \| D3 OFF~~
	~~:set would be HI, reset HI, CLK \| so D LO(doesn't matter) no change !Q stays HI so OFF~~
	~~once water falls below lower sensor out1 HI~~
	~~:set would be LO, reset HI, D would be HI(doesn't matter) CLK would be LO, !Q would and pump would be ON~~

	~~What happens when power comes on with the pond partly filled??? (pump off would be good)~~

	~~once low sensor is covered out1 LO D2 OFF, upper sensor uncovered out7 LO, Clk LO~~
	~~:set would be HI, rest HI, D would be LO, CLK would be LO, no change from ???~~

	~~you would like Q to be LO (!Q HI, pump OFF)~~

	~~since D would be LO, if LO could be forced on Q, !Q would be hi and the pump would stay off. That could happen if we could get clock to issue a rising pulse.~~

	The only time clock issues a rising pulse is when j2 shorts or its resistance is lower than 5.1M. or when the voltage on pin 5 is greater than the voltage on 6. How can you make that happen for a minute?? charge a capacitor somewhere, maybe inline with some resistor. which one??

	~~<s>you could short out r8 5.1M Once the cap is charged it would look open and back to just the 5.1. But at first it would(oops no current path to ground)</s>~~

	~~with no current flowing through the 5.1, the voltage on pin6- should be 5v (it is 3.6 vs 2.5 on pin5-) so - wins . + could win if the upper r6 was temporarily shorted~~
