I've been putting more updates on Crowd Supply on the state of manufacturing etc, while keeping things here on Hackaday.io more technical, but I thought I should put something about it here as well.  Manufacturing is an important part of every project that makes it to becoming a product, so it's important to share the good and the bad of that as well.

After some initial stumbles with the quality of the first article, PCBWay did better on the second try so I had them produce the rest of the 1000 piece order. So after not too long a wait I received a large shipment:


Very nicely packaged. And good quality product. I have not run into too many issues after testing and final assembly of several hundreds of these boards. I had one board that needed reflow of the TPS61236P boost converter. A couple of panels had this weird issue where the mouse bites to separate the boards weren’t all drilled:

And there was one board that had some cosmetic damage:

But overall, production has been running smoothly. The red light issue fix I implemented on the revision 5 boards seems to have completely solved that problem, which is a relief. Demand for the product is looking good and with the quality boards we received we are able to keep up with it comfortably.
