People with two or more cats often have one cat eating way too much food leaving the other pet starved. The chubby cat tends to eat all the food before the other one gets to it. It is also tedious to control how much food each cat gets.

Solution and features:
We aim to solve these problems by designing an automated system which controls how much food is given to each cat. The system stops the cats from eating each others food and controls how much food and at what time the cats are being fed.

A desired quantity (weight) for food can be entered. The dispenser, will have a flap door that opens/closes based on feedback from a weight sensor placed under the area/bowl the food is dispensed. Times the food is dispensed when a cat approaches can also be controlled to control when the cat eats.
The food container will have IR sensors/LEDs to indicate to the person if the level of food.

Cat Detector:
Methods to detect which cat is approaching:
RFID detection: most existing dispensers / gates use RFID concerned about IP
Cat collar color detection: The part of the collar on the cats back will be distinctly colored and will be detected by a downward facing camera.The camera will take a picture as the cat approaches the device. A motion sensor can be used to activate the camera.
A sliding door to close the access to the food bowl if the wrong cat tries to eat the food.

All the above functionality can additionally be controlled by the owner of the cats using an attached screen.

Power Considerations:
The device will be powered through the wall socket and we will implement a voltage regulator to appropriately power our PCB.

Featured Project

There is a drastic lack of networking infrastructure in unstable or remote areas, where businesses don’t think they can reliably recoup the large initial cost of construction. Our goal is to bring the internet to these areas. We will use a network of extremely affordable (<$20, made possible by IoT technology) solar-powered nodes that communicate via Wi-Fi with one another and personal devices, donated through organizations such as OLPC, creating an intranet. Each node covers an area approximately 600-800ft in every direction with 4MB/s access and 16GB of cached data, saving valuable bandwidth. Internal communication applications will be provided, minimizing expensive and slow global internet connections. Several solutions exist, but all have failed due to costs of over $200/node or the lack of networking capability.

To connect to the internet at large, a more powerful “server” may be added. This server hooks into the network like other nodes, but contains a cellular connection to connect to the global internet. Any device on the network will be able to access the web via the server’s connection, effectively spreading the cost of a single cellular data plan (which is too expensive for individuals in rural areas). The server also contains a continually-updated several-terabyte cache of educational data and programs, such as Wikipedia and Project Gutenberg. This data gives students and educators high-speed access to resources. Working in harmony, these two components foster economic growth and education, while significantly reducing the costs of adding future infrastructure.
