0-10 Minute feeder timer project in 15 Minutes!

Hi all,
I wanted to contribute something after reading thousands of interesting articles through the years on this forum. I recently moved selling off most of my equipment in the process. All of my custom cabinets had built in timers for feeding purposes. I have recently started up some nano tanks and missed my timers for feeding, so I did a quick search and found nothing of interest for the cost. I used to use Omron timers but they are around $250.00 each. I went at this with a low tech approach this time. I found a timer on Amazon that is used for protecting A/C compressors from rapid cycling. It is a simple delay circuit that cuts the power after you press the button for a preset amount of time. The delay can be set between .03-10 Minutes. I have found that 10 minutes is a perfect time for my needs. I can feed the top water and mid water swimmers easily before my filters come on and eat all the food up. I put it all together in 15 minutes...I wasn't trying to win award for a clean look as it sits inside my cabinet next to the food. i built this in a standard plastic 2X4" electrical box and everything fit nicely. It could have been housed in a 4X4" box with s socket easily...The best part is, it cost under $15.00 to make! The most expensive part is the timer module. I found many different higher prices for this, but Amazon has it for $5.50

Hope someone can use this,

There are definitely people that can use this. I'm glad someone finally came up with a low cost solution

This is a really useful project, thank you.

Finding this type of timer in an electronics shop is pretty much impossible, let alone in a BestBuy kind of store.

Nice little project. I think I need one! If anyone is trying to source one of these timers locally, they're commonly used by air conditioning service people. I would imagine they're used in many small appliances. Any AC supply house should have loads of them.

You would connect your filter to the auto shut off. When the button is pressed, power is shut off to the connected equipment (in this case, the filter) for a specified time (e.g. 10 minutes). After the selected time has elapsed, power is restored.
