I've finally gotten around to making a printed circuit board for the midi controller.  It took a fair amount of time because I had select and learn how to use both schematic and pcb design programs.  There are quite a few out there but I ended up using Cadsoft Eagle PCB.  It's free, pretty simple to use, has an autorouter, and it can generate either gerber or Eagle files.  I had the boards made at OSH Park which accept Eagle files directly which really makes it easy to upload once you are finished.  


When I created the board I hadn't yet learned how to manually route traces so I used the autorouter feature.  I later learned that alot of people don't like autorouters because of the inefficient way it might route your traces.  This is especially true if you want to do something like place decoupling caps next to your IC's.  The traces should run as direct to the power and ground pins as they can, but if you use the autorouter they might end up snaking their way all over the place.  Now that I know how to manually route traces I can at least do the important stuff first by hand, then use the autorouter to finish the rest and adjust any traces I need to when it's done.

OSH Park makes PCB fabrication very affordable.  They may not be the cheapest around but I had 3 boards made for about $33 bucks.  You have to buy them in lots of 3 so I figured in addition to the few signals I needed from the Teensy Microcontroller, I'd breakout the rest of the signals onto IDC header connectors so I could use the remaining boards for other projects.

So, here is the OSH Park Rendering. I just got word that it's been shipped so I'm eagerly awaiting it's arrival.
