Porcupine
From Capsil Wiki
The Porcupine [1] is a small wearable sensory unit for logging motion data and doing low-level activity recognition. The project includes electronic schematics for the hardware, software for the microcontroller and client-side software for hardware-interaction.

The Porupine being a wearable sensor is mainly used for activity recognition through users actions. It has been involved in a number of projects to date to include:
- Actigraphy for Bipolar Patients
- Activities of Daily Living (ADLs)
- Daily Activities Annotation & Recognition
- Gardening Activities
- Long-Term Sleep Study
- Smart Electronic Dice
- Sports Training Activities
Power
The board contains charging circuitry and is designed to be worn 24/7 without having to recharge its 3.7v battery in between. According to the online documentation, the Porcupine should log data non-stop for weeks with a minimum of user interaction.
Software
The CSS compiler is used to program the PIC.
