need some eyes for this simple LM393 ckt.
do 393's bounce when V- = V+ thus need feedback, i cant have the SSR (VO1) flapping, etc. is gnd'ing all the pins on unused comparator in the 393 the right way to terminate it?
393 is a common collector sink. and not shown here, but VO1 is a SSR switch for four 60w PS's. the PS's are 120vac-12vdc for landscape lighting zones. i'll also show later, but the loads on each PS (aka "zones") are actually controlled by a 4ch PWM module driving power FET's. the module has wifi and a app for iphone/android and you can manually control zones and create saved "scenes". i looked for COTS but the systems were like $k+ and the lamps are ~$100ea (i'll have ~28 lamps in my backyard). i think my whole system is on order of $300 and plain 'ol 12vdc anything for lights work (my system is made for LED but is not rgb, thus limiting to 60w per zone, but if you needed more power just replace PS with a bigger one, the FET's can handle lots).
