Simple count up timer for coffee machine triggered on mains voltage detection using CT on the coffee machines solenoid valve. CT is SCT-013-005
Note this is a slightly modified layout to the first board to space out the components better to allow easier soldering also change ICSP to staggered layout (circuit is identical)
Simple count up timer for coffee machine triggered on mains voltage detection using CT on the coffee machine solenoid valve. CT is SCT-013-005 (5A) PCB is designed to fit custom case such as http://www.ebay.com/itm/190966512623?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
Has been tested and in Production June/July
