At LCA2012, I spent some time learning about the poster child of the Open Hardware world, Arduino.
Here’s a demo video I made of a Raining display on the LCD.
It uses the Pebble v2′s 20×4 LCD display and custom characters to display a “rain” effect (the LCD needs to be mounted sideways, as shown in the video). It could readily be extended to have different levels of rain based on CPU load or net traffic, or some other monitorable metric.
I have a new hobby!
