    My day 3: build a gsm monitor/alarm for a pump house

    Seems to be working ok, as in texting and calling. The mains relay's I have used are getting too hot, seems that the led resistor is of the wrong value so are dissipating too much heat. Have started to do it another way for the mains monitoring.

    House water pump keeps needing a reset

    Hi. I have a single phase water pump which supplies our house. It frequently cuts out and needs to be reset (on pump itself). Because of our location (rural Spain) I suspect it is erratic voltage supply. Is there a power regulator I can use in between pump & outlet to overcome this?
