Oh my, oh boy, oh great! You may recall that I went cray cray over the O Watch developed by my fave young engineer Omkar. Well, the watch is now out and people are hacking this open source beauty to make it their own, including the name. This D Watch was developed by Dennis Ward and you can check out his details for this extension on Hackster.io. He’s got the watch reading out temperature as well as relative humidity, so now people can give weather details on the fly.

Omkar’s watch uses TinyScreen with a TinyDuino platform, which makes sense since this all fits in a small case. The new menu option makes use of the additional sensor board, which uses a few Adafruit libraries. The right button on the watch is re-purposed to show the temperature and humidity information, which Dennis attributes to the simplicity of Omkar’s design.

This is a very simple extension of the O Watch code and is meant to be a proof-of-concept to show how this device can be customized in as little as 30 minutes by anyone who was able to install and run the O Watch sample code.

Although this hack centers on the code, the O Watch also includes information to 3d print a case at home, as well as create a watch band. So, there are many ways to customize, whether it be for function or fashion. If you are a watch fan, you may want to also check out our Solder: Time II DIY Watch. It’s also Arduino powered using an ATmega 328P, so you can have fun customizing with graphic messages, crazy characters or whatever is trending in your life. Have fun showing off your maker style with a DIY watch of your own.
