I believe that I have waited long enough and that I am the last. I am sad to report that i still have not received my boards and unfortunately I ordered 10 sets. I have asked Quanghao in a private email and not received a response so I am now asking here in the open.

1. Could you please confirm the shipping address you used when sending out the boards to me?

2. Is there any reporting to your mail carrier that can be done to begin a trace on the package?

3. If there is a second run could my order be filled from that?

4. Can I please get the files to make my own boards?

Lastly a thought for all who participated.
I realize that shipping problems are not your responsibility, but in the group interest of pooling resources to save it seems that shipping losses might be shared, sort of a group insurance. Just as it seems unfair for Quanghao to make good on the loss since there is no profit it seems unfair for me to have paid and received nothing. As this could potentially happen to any of us we might as a community consider how we can help each other out in this regard.

Thanks for listening.

You're out of luck!
As such, I will try to get you on the 2nd, because now I do not have PCB!
In group 2 times this size and smaller motherboards will not run at 1A

~50mm shorter. Well done.

I do not like the way you have connected the rectifiers to the +ve & -ve supply lines.

The rectifiers should supply the smoothing cap and then the smoothing cap should supply the +ve & -ve feeds to the regulator.

The sense traces are still spread across the width of the PCB and do not sense the output terminal.

Considering that over 6% of the orders were never delivered and almost 11% of the boards went missing, would it be possible to ship via a method that allows tracking? It would also be nice to offer insured shipping for the larger orders, or break up the shipment into multiple smaller ones. In all of my years of ordering and shipping I only know of one instance of a package being lost in the US mail. Others can report their experiences.

Alternatively we could all decide to self insure adding a 10% surcharge to everyones order to cover apparently expected and "acceptable" losses. The spirit of a group buy is for like minded individuals to band together toward a common aim. Sort of a one for all and all for one idea. Sharing information and pooling resources saves everyone time and money, but if everyone isn't supplied the benefit the real costs are not being shared. I don't think I am prepared to gamble again and don't see why any of us needs to.

Lastly I have already purchased the parts for 10 sets of the original 4 circuit board layout. Assuming that there is no problem with this design as people start to build them up, I don't want to loose the low voltage board. This was in fact a large part of why I ordered so many. If the new round isn't going to include this then I would be happy to price out a run here in the US for the original design, assuming it can be used.

P.S. I might also suggest that IMHO there is little benefit to the Gold other than cosmetic. If it was a significant cost factor I at least would be happy to not include it. Others thoughts about any of this?
