I need help in identifying a product that I saw on a hunting show a year back or so. It is a device that you could attach to your own homemade pvc pipe feeder that would release feed/corn only at certain times. You could buy a timer to go with it. Does anyone know what I'm talking about?

Not sure what you mean,but why make it complicated.Go to Walmart ,get a Kenco Smart Timer,then get an empty drywall bucket and your all set...
