SIPR (sounds like "sipper")
What it does
SIPR keeps track of your can. The web page shows you how much you've had to drink and when you drank it. The koozie has a display which both shows your drink count and flashes party lights.
How I built it
SIPR uses an accelerometer to determine when you're drinking. The accelerometer also knows when you finish a can by detecting a double tap. We used a PSoC to control the electronics. It communicates with the web page through a laptop for the demo.
Challenges I ran into
We encountered some problems getting our hardware to work. We had to learn a lot of new skills to get stuff done.
Accomplishments that I'm proud of
Very attractive website. Glowing LEDs.
