Interested in making a simple, but useful circuit? This article will help you to design and build a watch that shows the time in the binary format. The design is pretty simple and only a few components are involved. Read on to know more about this.

The requirements of the project are listed as follows:

• LCD interface
• eZ430 development board
• CR2032 power source for the development board
• Ipad Nano watch case

All the components are fitted inside the Ipad case which gives a watch-like look and feel. To achieve the binary codes for the current time, C programming has been used.This ensures that the user is able to learn and modify the code as per his/her requirements.

The display can be used show the alphanumeric data, text messages or other details too. But as themsp430-2013 has been used in the project, it is very difficult to sum up that many details on the display. Moreover, if needed the user can use a larger development board in order to display more information on the screen.

The source code that has been used in the project can be downloaded from http://41j.com/blog/wp-content/uploads/2011/09/msp430_watch.tar.gz
