Kicad BRD files --> Gerber Files for OSHPark Service!

So as I reverse engineer one circuit, I really REALLY want to send this led heart one off to be made, even if when I get it back, I'll realize I've done something dumb :p.

OH.WELL.  It's time to go and be made.

So that's the *.brd file from KiCad.  According to directions posted: http://reprap.org/wiki/KiCad and https://code.google.com/p/opendous/wiki/KiCADTutorialCreatingGerberFiles I need to go to Plot then select:

Once you hit Plot,  you end up with those messages.  Essentially one file per layer.

Back.gbl + Front.gtl + SilkS_Back.gbo + SilkS_Front.gto + Mask_Back.gbs + Mask_Front.gts + PCB_Edges.gbr

Now it's time to generate the drill file - all I did was uncheck "Mirror Y Axis":

Alright. So now I press OK and choose a file name for it.  Next to do some proofing!

Evolution of the Heart Project Schematic

So I'm working on that heart project and trying to make a pcb for it.  But to do it, I need to make a schematic for it.  So by just thinking about what I needed, I drew out the following:

Pretty isn't it?  It doesn't really have the labels but Brown is the Propeller chip, and going counter clockwise, green is the crystal, red is the EEPROM, light purple is the programming pads. Teal is the voltage regulation, blue is the switch, and the magenta is the LEDs.  The weird pukey yellow is the battery and ground.

So then I got some initial feedback which was like "Uhhh....":

It's important to hook up all 4 sets of power and ground on the SMT 44 pin Propeller and to put decoupling caps near each pair.

The EEPROM needs to go to power and ground as well.

Pull-up/down resistor on the reset button.  As the pin connects to ground through a resistor, the switch connects it to power to toggle the state

So here I'm feeling pleased as punch, and then I got "uhhhh...":

Need to add in the reset and ground pin to the programming pads.

Put the BOE to ground as well

Change where the resistor is in relation to ground and the switch.

Need to change how the decoupling capacitors work since decoupling capacitors go between ground and power rail.

Woot.  So I'm still looking for feedback on functional items I need to add in.  I know that I have /way/ too many separate lines going here and there to ground and that they can be consolidated.  But for my first one, I prefer to know exactly what's going on with each pin.
