I got approached by PCBway who wanted to sponsor a batch of assembled prototypes.

It was a rather significant amount, so thank you again! PCBWay went out of their way to sponsor it, way to go!

PCBs have just arrived from PCBway, many thanks for supporting this project by sponsoring the PCB's. They have come out looking great, everything is very sharp and the finish is good. Their customer service was very helpful and responsive which was great.

The board worked as soon as I plugged it in. So far I haven't tested all sensors, that will come later., 

Other then that I don't really have much else to report, everything works and its been a great success, I couldn't have hoped for a better outcome so far. Now I'm just back to writing firmware which is going to take forever for me. If someone has many of hours of free time on their hands good, I don't. Thanks again to PCBway for supplying pcbs for this project, I do really appreciate it. 

The PCBs are rather costly due to being fully SMD flex-PCB, which is a really challenging process.

Attached is a macro of the flex PCB.

One good thing about PCBWay is that they will source all components for you, you don't have to rely on pre-sourced in-stock components and separately buy them, as with other PCB manufacturing outfits. Also, my PCBs arrived sealed in antistatic bags, which was a nice touch.

One last thing, PCB Way will send you pictures of the assembled product before shipping, for you to visually check the assembly. This is very helpful if you know certain component orientation is tricky, such as photodiodes, diodes, or other small polar components. I've had cases in the past where some component were rotated incorrectly and seeing a picture before shipping helped.
