An OSS Watch for your wrist!

At OSS Watch, our name means we get a lot of spam offering to sell us watches, so I decided to find out if there really is an “OSS Watch”. It turns out there is, or at least, an “OS Watch” since it’s more about the watch being open than the software it runs.

The Open Source Watch website provides details of the components to buy, the tools you’ll need, and schematics for 3D-printing the casing. It then has detailed step-by-step guides with photos showing assembly of your own homebrew smartwatch.

The device as built on the site features a 1.3″ OLED screen (the site also suggests other options), bluetooth connectivity, vibration and LEDs for notifications. The whole thing is powered by an Arduino-compaitble microduino (underclocked to save power), and runs off a 500mAh battery with micro USB charging. You get 3 tactile push buttons, a power switch and a port for programming the arduino.

The site doesn’t provide dimensions for the finished device, but by my esimates the face is 40x60mm, and the casing is about 30mm deep. So it’s fairly chunky as you’d expect from a smartwatch, but doesn’t look over the top considering it’s a DIY job.

The software to run on the watch is in development and available on Github. There’s currently some code to display the “watch face” using the arduino, and the beginnings of an iOS app which will presumably send notifications and data via bluetooth.
