The DIY Smartwatch

This is one of those kinds of DIY projects that excite us. Simple, straightforward and unbelievably effective.

This wearable smartwatch has four function based sections – 1) a battery charging circuit 2) a vibrating motor for silent alerts 3) a programmable Arduino-compatible core with power modulation 4) a Bluetooth LED and an OLED display with pushbuttons.

Jonathan, a hacker by night and an amateur artist, instructs in a plain no-nonsense manner how to go about building it. The circuit diagrams are in plenty, and as detailed as they can be.

The result is a low powered open source watch in a 3-D printed case that can display time, text, alerts and room (large spare memory) for add-on features. It has a battery life of minimum 1 day and a 100% arduino compatibility.
