The Eez clock was created with the intent to notify a concerned parent about the general whereabouts of their distant child and whether the child has eaten all the meals for the day. A tutorial has been published on the Instructables website for other makers to re-create. The Instructable was awarded second prize in the IBM Watson powered IoT Builders' Contest.
Eez uses the location data from the child’s smartphone and turns the clock hands to one of three positions: Home, School or Elsewhere. These can be configured depending on the user’s frequented locations. Three LEDs on the clock hand, representing the three meals of the day, light up based on buttons pressed by the child on their phone. At the end of the day, if all three lights are on, the parent would be relieved and happy to know that the child has had food throughout the day and at midnight, the lights automatically turn off.
Eez works with Adafruit’s Feather Huzzah Wifi board, in conjunction with If This Then That (IFTTT) and Adafruit IO (a platform to create simple Internet of Things devices). Location based applets on IFTTT send data to a feed on AIO based on where the user is and IFTTT DO buttons on the user’s phone can be triggered manually each time they have a meal, which is sent to another feed on AIO. These feeds communicate with the Huzzah board and cause either a servo to move to the appropriate location or the relevant LED to light up.
Being a DIY tutorial for Instructables users, the body of the clock was made using materials that were available to me, in order to reinforce the idea that the shape and form can be made as per the user’s preference of any fidelity, with whatever materials they have. I chose to cast the form in concrete using disposable food containers of appropriate sizes to fit the circuit and all other components at the back.
