So Bkkcoins: will you be producing K64 boards (4 K16 all on one PCB board) or no? Wondering how Terrahash will be getting the K64 boards for the DX large boxes...

I doubt I'll actually produce any boards or design layout for K64 - though technically I kind of have one in my hand right now. A 4up panel of K16 boards. A good layup of a K64 would join the klego pins and remove extra connector pads to save parts. However, joining together all the 12V power is difficult and would require a connector assembly that could take 4x as much current. It is probably is feasible to join each pair of K16s into one PCIe connector and save on 2 anyway. I don't think K64s should be built until working K16s are tested in chain configuration.

BKK UPDATE:

I picked up first revised K16 samples from Bkk yesterday and will be working to build a final test unit now. Also, my first bulk board order arrived in Bkk today but I won't be able to get them until Monday (after I build one here).

Other notable updates:

Have solder paste and tweezers for web orders but need to pick up SD cards still. I ran out of time yesterday - but no worries yet as the final firmware and driver are not ready anyway. I did a test of solder paste before going to Bkk to confirm between two batches. Turns out the cheaper batch was garbage. I mean literally - hardly no solder in the paste. So scratched that place off my list and went with the stuff that balls up and makes nice silver joints as it should. Unfortunately I'll be selling for about the same price I buy at now - which isn't a problem as I wasn't really expecting to make anything off these accessory add ons. Just so people know the solder paste I got is XG-50 not MCN-300. Apparently this is the new version and the jars I have are all June 2013 instead of Sept. 2012 (which is what MCN-300 would be). Checking again once home I saw that XG-50 is what I used on my boards and MCN-300 is the jar I took a photo of. Doh! And getting finicky it looks like the jars have 42g now not 50g - but that's better than getting older paste.

I have Klego connectors in hand now and Klego PCBs arrived today in Bkk along with my K16 boards. K1 boards still 5-7 days out probably.

And for anyone who wants I'll have a PIC16LF1459 breadboard adapters in the K1 batch too. Allows mounting the PIC with USB and power reg. in a breadboard. Size is 16mm (0.6") x 50mm (2"). I just made these up to fill a void in the order and allow me to have a platform for doing the PIC programming without messing up K16 boards, and they'll be handy for future prototyping projects.

All the PICs, both QFN and SS, arrived as expected. So now it's mostly a matter of finishing firmware changes so I can program them ready to ship with boards next week.

Oh ya, this one's important. I couldn't get K1 Heat Sinks this time. All the stock had been bought up and they didn't know what I wanted (my Thai is not so good, actually it's pretty terrible). I'm going back with my sample pieces again but I may be looking for an alternate supply now. which is a real drag as I thought I had a good supply worked out.

Word I got from Microchip is that they are making PIC16LF1459 to order. So they won't appear on store shelves if you're waiting. You need to place an order with Microchip Direct to trigger the production allocation needed. If people had placed their orders back in June they would be on hand now.
