I had posted earlier about using a timer to interrupt my pumps for feeding. Well I have completed the project and I am here to report on it.

WARNING a basic understanding of electricity is highly advisable before starting project.

Parts list
1 Intermaatic timer FD32H (SPDT)
1 dual plug box with custom made strain guard
1 outlet from home depot
1 face plate
1 used cord from old computer

The heart of the unit is the switch. The FD32H is a SPDT switch so it has a normally closed position. it is the shorteds time timer Intermatic makes at 2 hours. I verified Line 1 and load 1 were the NC terminals, and they became the interrupt.

Parts

On this cord the brown wire was the hot side, so it was the one I chose to interrupt with the timer.

Wired

Plug and timer in box

Complete unit

Total assembly took about 30 minutes, and now I will never forget to turn my pumps back on after feeding.

I got the timer on eBay, but you can also get it at this link.

It was less than $40, but I love the fact that I will no longer lay awake at night wondering if I turned the pumps back on.

Nice package. Looks like this will work well. I may try this route. Thanks for the link.

That's slick!!

I have been working on something similar in my head but I always seem to go overboard, and do it digitally

I've been contemplating upgrading to a PLC (Programable Logic Controller) for my entire tank(s)

Very easy solution!! I like it.
