Hi. Has anyone worked out a way to allow ponies/horses to be given hay automatically so that a person doesn't have to be there to just give hay e.g late evening or when the owner is at work? I have a lengthy journey to my ponies' field. I do have helpers who are willing to visit my ponies during the day but not late at night! I have been thinking about an idea which uses weights attached to the lid of a container. Hay would be put into the container & a weight is attached to the lid. A bag of sand would be attached to his weight. Both would be draped over a fence behind the hay container. The sand bag would have a small hole in it so that the sand comes out of the bag at a specified rate e.g. a 3 kg bag of sand might lose sand at the rate of half a kilo per hour so taking 6 hours to empty. The reduction in the weight of the sand bag would eventually allow the weight to drop thus opening the lid of the hay container. I have found examples of automatic gate openers but these seem to be really expensive & complicated to install. I think I need to get in touch with an amateur inventor LOL.
