My eagle schematic is a bit sloppy, but I hope it is clear enough to understand the general idea. I'm using the ever popular atmega328p in a less popular tqfp package for the microcontroller, the slightly esoteric ds1302 for timekeeping and the wildly popular ws2812 led for readout.

This step was a lesson in eagle-fu for me, as I learned how to use a few handy scripts and techniques. Chiefly, the cmd-draw.uld script for creating the circular pattern of led's, and the witchcraft that are ground planes. Sparkfun's tutorials are an excellent resource for learning these. That is, if you wish to continue an unhealthy addiction to a product with inflating prices.

I also followed sparkfun's tutorial on making new part packages, as my choice of RTC had no surface mount eagle part. If you'd like to cheat, you'll find the library I made attached.

Next, I'll show you how I prepared my design for printing and toner transfer... After my homework is finished.
