I need some assistance in my latest endeavor to build a programmable automatic dog feeder. The primary reason for this is the cost of the ones I have found in stores and online, and that they are to small. Programmable timers are easy to come by and quite cheap. The harder part to come by is the auger device to dispense the food. Does anyone know of any source for this type thing? Ideally I would for the stepper motor to be attached via relays, powered by low-voltage and have a 9-12volt transformer attached with keeps the nicad batteries mantained at all times, however should the power go out the unit will continue to function off battery power. Any suggestions?
TIA,
