Meet Ember: a smartphone-enhanced coffee mug that keeps your coffee at the right temperature for up to 2 hours. It has a dial that lets you change the temperature. You can also make changes from your smartphone. In fact, the app lets you name your mug, remotely adjust the temperature of your coffee, and save different drinks.
Ember is waterproof and leak-proof. It simply keeps your tea or coffee at the right temperature for longer. More information about this project is available on Indiegogo.
