Chris Burns wanted a project to sit on his desk and be a conversation starter. He had an interesting idea centered on using a business card holder to display his project.
Out of this concept, the LEDC was born. It is a tiny LED Matrix clock chock full of features.
At first glance, it is deceptively simple -- a display, a couple buttons, a battery, a PIC18, and not much else. Chris has packed this unassuming package with a ridiculous amount of features in the firmware. He shared his project on Dangerous Prototypes and highlighted the following features:
Low power battery operation
Traditional digital clock mode
24 hour military style digital clock
Binary coded decimal clock mode
Binary Clock mode
Scrolling Date text mode
Hour Glass count down timer
Dice rolling mode
Scrolling text message mode
Built in buzzer for alerts with selectable volume
3 independent alarms
Multiple chime options
Multiple power saving options
As you can see, it really looks right at home in a nice business card holder. Chris has shared his schematics and firmware on his personal blog if you want to replicate this fun little time keeper.
