Try Ultramatic feeders or Magnum Hunting Porducts. The both put out extremely dependable digital timers along with some of the best spinners Ihave ever used. The spinners have flaps on the to keep the corn thieves from getting your corn. These timers, linked up with a good 10 watt solar panel and a decent 12 volt , 7.5 amp hr batt and you will run the season or longer with no problems with it ever not feeding. MPO.
