A project log for 6 inch Pi E-ink display

Make a board to interface the Raspberry Pi with a surplus Kindle screen. The smaller and cheaper, the better

I already have all of the components ordered, the only thing holding me back is designing the PCB.

I have the schematic (mostly) made in Eagle, but the board layout is where I'm having trouble. Also I ordered a bunch of different sized components which was a major mistake on my part. I have to keep referencing the packing list when placing the parts on the schematic to make sure I get the right footprint. And a few of the parts I'm using aren't available in any Eagle library I could find. I did find the connector for the display, without which this wouldn't have been possible. I know you can make a part, and it seems relatively straightforward enough, I just don't trust my limited skills with this software.

The LM78L15ACMX isn't available, so I'm using this similar part for the footprint. The only thing I'm worried about is that it may not be numbered the same and I might be routing all these pads wrong. Either way, it's a learning experience, and I have plenty of time before the deadline to get something up and running. I'm going to do some work on it today and try to get the schematic and board finished. After perusing it to make sure all my connections are correct and all my parts are in the proper footprint, I'll send it off to OSH Park to be fabbed and cross my fingers.
