Hello! Welcome to another Other Machine project tutorial! I'm Sam DeRose, a former Other Machine Co. Summer Intern. I created the Nerd Watch last summer while working at OMC.
The Nerd Watch displays the time in binary when the button is pushed. The watch shows the hour and minutes by flashing two LEDs in sequence to represent two 4-bit binary numbers (in big-endian format). Here's a great description of how to read binary numbers.
I'll show you how to build a Nerd Watch from scratch with a few electronics components and an Othermill.
This tutorial presumes you have previous experience working with surface-mount electronic components and that you're no stranger to a multimeter and soldering. It's also helpful to pick up a little information on how Arduino works.
