About The Smartshelf

What we designed:
We created a system to help people with weightloss. It provides haptic feedback to inform dietary decisions. Our implementation included 3 containers in which food with a RFID tag on it could be placed. The system would diagnose which food was in which container and then provide power to an electromagnet within the container. The end result is that bad food is harder to take out of the fridge and good food is easy.

Prototype Components:
We used a java program we wrote, a RFID reader, 3 electromagnets, a handyboard microcontroller, 3 relays, and an external battery. Here is a picture of how it worked.
