What is better than making your own smart watch? Making one with an OLED display. This is exactly what [Jared] set out to do with his DIY OLED smart watch, which combines an impressive build with some pretty cool hardware.
When building a DIY smart watch, getting the hardware right is arguably the hardest part. After a few iterations, [Jared's] OLED smart watch is all packaged up and looks great! The firmware for his watch can communicate with the PC via USB HID (requiring no drivers), contains a “watch face” for telling time, includes an integrated calendar, and support for an accelerometer. His post also includes all of the firmware and goes into some build details. With the recent popularity of smart watches and wearable electronics, we really love seeing functional DIY versions. This is just the beginning. In the future, [Jared] plans on adding Bluetooth Low Energy (BLE), a magnetometer, a smart sleep based alarm clock, and more! So be sure to look at his two older posts and keep an eye on this project as it unfolds. It is a very promising smart watch!
With Android L including support for smart watches (in the near future), it would be amazing to see DIY watches (such as this one) modified to run the new mobile OS. How great would it be to have an open hardware platform running such a powerful (open source-ish) OS? the possibilities are endless!
