![]() And the client, and more importantly, the cat, love it. Overall, and much to my surprise, the dang thing works. The code has built in checks to monitor the status of the hopper, check the end stops, and provide a timeout for the homing sequence to detect any jams. ![]() The user interface allows for programming of the feed time, as well as manual dispensing of food, and clearing of the hopper. The user interface is a regular 2x16 LCD, with an AdaFruit LCD backpack shield. The stack includes two shields from AdaFruit a motor shield for the steppers, and a servo expansion shield for the servos. Power is provided by an SFX power supply hidden in the bottom chamber, which outputs both the 5v and 12v needed for this machine. This board makes it easy to wire up all of the end stops, DC motors, and provide power distribution. The I/O board was custom designed and etched, and sits on the bottom of the stack. On the electrical side, all processing is handled by an Arduino Mega 2560 (yes I know, I could have done the whole thing with a 555 timer :P). The project presented many hurdles, including how to reliably dispense a can onto the trolley, how to reliably open the can, and how to remove the lid (it turns out it was aluminum, thwarting a simple magnetic solution). Lid and empty can are disposed into the trash bin Trolley advances can to cutout, then flips the can upside down onto waiting plate Vacuum cup grabs onto the lid and removes it Trolley grabs onto the can and advances it to the gantry Hopper dispenses can into waiting trolley The simplified operation procedure goes as follows: The steppers control the track and the gantry the servos control the dispensing, gripping, and flipping of the can and the DC motors come in the form of a vacuum pump and can opener. ![]() It includes five separate chambers for feeding your cat, allowing you to store up to five meals at once. This feeder is compatible with both wet and dry cat food. ![]() It is powered by an array of steppers, servos, and DC motors. You can effortlessly time your cat's meals with the ORSDA Pet Auto Feeder for Small Dogs and Cats. The rest of the parts were fabricated out of wood, Polycarbonate, and UHMW PE. The machine was designed in CAD, and is mostly comprised of 3D printed components, with some mechanical essentials like bearings, linear rods, etc. Function for clearing hopper for switching out food types. Programmable feeding time for each day, with built in manual override. Built in trash bin for the lid and the empty can. This can be theoretically expanded infinitely, and is only limited by space constraints and mechanical material strength. Want to learn more? Read Your Guide to Fleas, Ticks and Worms.- Hopper large enough to store nine cans enough for nine days of feeding. Looking for something else? See all products from Nexgard. Weight Rangeįor dogs over 50kg, administer the appropriate combination of chewables. Not suitable for puppies under 8 weeks and under 2kg, pregnant or lactating animals.

Learn more about what level of protection your dog needs. NexGard is highly recommended for dogs who live in a high risk tick area (such as the Eastern Coastline of Australia.) It does not provide protection against intestinal worms, heartworm, or the hydatid tapeworm. NexGard provides protection against fleas, ticks, and mites. It comes as a soft, tasty beef-flavoured chew which your dog will love. Nexgard protects your dog from fleas, ticks and mites for a full month. NexGard Small for Dogs weighing 4.1-10 kg
