What time is it? The TimeDock Sleepeasy will tell you


This interactive docking station allows your Pebble Time smartwatch to talk to you with a wave of your hand.


Picture this. You’re in bed, wondering how much time has gone by since you haven’t been able to fall asleep. What if there was a device that could tell you the time so you didn’t need to put your glasses on to find out? At the Pebble Rocks Boulder Hackathon, one team devised a gadget to solve that specific problem.

The TimeDock Sleepeasy is an interactive docking station for your Pebble Time smart watch. The gramophone-like unit allows you to find out what time it is, without having to turn on a light, press buttons or touch the Pebble while it’s on the dock charging. Even better, the device will read the time and talk to you, so you don’t need to do anything except wave your hand.

Inspired by the old-fashioned gramophone, the team created a 3D-printed mount embedded with an Arduino Uno (ATmega328) inside. The 3D design enabled the sound to be amplified mechanically, resulting in a gramophone look-a-like. The Arduino then communicates with the Pebble and leverages a sensor to respond and tell you the time.

The group figured out how to get the Arduino talking to the Pebble, and they used an ultrasound sensor so that users can wave their hand at the TimeDock and learn the time. To open communication between the Arduino and the Pebble, the team configured the ATmega328 board to send a request to the Pebble for the time, then programmed the Pebble to reply with the time and a request to say it. Its creators loaded .WAV files on the Arduino for a range of other notifications programmed on the Pebble — when the Arduino gathers information on the notification, it plays the corresponding .WAV file.

“TimeDock was developed as a charging station for the Pebble Time and Time Steel, and was a successful Kickstarter campaign. For this hackathon, we wanted to see if we could make TimeDock do more than charging. The TimeDocks that you see in use in this article have been modified to allow connection to the smart strap serial data port on the Pebble Time,” the team explains.

Mission accomplished! You can read all about the 48-hour build process on its Hackster.io page here.
