Maker creates a fully hackable, Arduino-compatible smartwatch based on the Atmel | SMART SAM D21.
Moritz Wenzel has emerged once again, this time with the latest iteration of his Arduino-compatible, software and hardware expandable DIY smartwatch. An upgrade of his earlier device, Tardis, the OwnWatch is completely hackable and enables Makers to connect their Arduino projects with both the wearable itself along with its paired smartphone via Bluetooth.
“Currently, every company on the market [has] built their own smartwatch, nice small devices that makes your life a little bit easier and more comfortable. But for a Maker, a hacker, a hobbyist or a nerd who loves hackable devices and creating own projects, these ‘boring’ smartwatches are no real alternative,” Wenzel explains.
For the OwnWatch, the Maker improved upon Tardis’ original housing and its hardware, most notably by replacing its ATmega32U4 core with an Atmel | SMART SAM D21 Cortex-M0+ MCU and providing additional BLE support thanks to a new dual mode Bluetooth module. Aside from that, the wearable is packed with a plethora of sensors, including a gyroscope and accelerometer, three temperature sensors, a pressure sensor and an ambient light sensor.
Meanwhile, power is supplied by a 180mAh LiPo battery, and audio can be emitted through its built-in speaker or a set of headphones. OwnWatch is equipped with two tactile buttons that allow a wearer to navigate through the main menu and switch between various functions like the time, calculator, image viewer and settings, as well as return to the home screen. A pair of programmable indicator LEDs can also be found on its frontside.
