    Basic circuit, but is this possible??

    I'd argue that it is wayyyyyy too early to be that confident given many details are not up front. One limiting factor would be the internal R of the "button cell" (type not shown). Another being the "555" as it normally needs between 4.5 and 15v to operate successfully. There are naturally...

    help with IR2110 chips

    Yes. When finished your layout you can submit it to JLCPCB for their checking. Naturally there are design rule checks you can set when you do the "generate PCB". After that you can ask for a price, watching your delivery options as I mentioned previously. As with anything, you have to learn...

    help with IR2110 chips

    Use the EasyEDA software and get a direct quote from JLCPCB .....couldn't be simpler. $2 for 5 boards (100mm x100mm)max Just watch postage I usually select the cheapest which takes around 10 days to Aus. $1.50 last lot. Can be $50 if you don't watch out for it and change it. [mod edit] changed...

    GE Washer Motor Control Board 5KMC145YTA008S Diode Rectifier burnt

    Could be equal to a 1N4007 or could be a zener....cannot see any number on the diode itself or any board marking. Either way, expect additional damage somewhere in the vicinity.

    Monitoring inputs and getting alerts on my phone

    On the pump stations, we used a phone dialler that would ring a predetermined number of people until an answer was received. I'm certain there would be a modern day equivalent available nowadays. Obviously you would need access to a landline or be within range of some phone network. Then you'd...
