I sent out the Headband Sensor Package Version 0.89 PCB's to OSH Park, Got three purple PCB's back, and they look great!

The top and bottom of the boards look pretty good. I could have flipped the resistor silkscreen (the R1, R2 and R3), along with the infrared receiver text so it all aligned, and the capacitor soldering pads may be a bit farther apart than I want, but all in all, it's a good first board. And, it's the first thing I did in upverter. I'll solder one up once I get the arduino shield PCB's in, and then I'll have the soldered version 0.89! (If you're wondering, there was already a soldered version, 0.42, but that one had some issues. It was made in Fritzing, and it was easier to make the boards again in upverter than try to fix the boards in Fritzing).

It's really easy to see the traces on the board. You can see how things are connected without trying too hard, which is pretty cool.
