Happi Cup

HAPPI CUP - IoT Assignment 3 from Vanessa Li on Vimeo.

Project Description

Happi Cup is the best reminder of your upcoming Friday! Every morning at 9:00 a.m. during the weekdays, the Pixel Ring lights up showing yellow color similating the beer, and the pump pours a certain amount of water into the cup, it will stop automatically after reach the required amount (approximately 2 minutes). The amount of the water indicates which day you are in according to the whole week and also how far away you are from the Friday Night! When Friday Night finally comes, the glass will be full of water, which indicates you are free! Go out join the party and grab a beer! This device can also show notification on some important things. The pixel ring outside shows blue color when his girlfriend updated on Instagram; Pink for his boss's email; And cyan for important calendar events.

Function

To enable the water pouring into the cup, we used a pump powered by 2 sets of battery cradle in total of 18V, by control the time of how long it runs to get the certain amount of water we want. And also to simulate the beer and enable its notifying functions; we used 2 sets of pixel rings to light up the glass, the one inside showing beer-like color, the outside one shows its functions of notification integrated with Gmail, Google calender and Instagram.
