Oh and be extremely careful with the micro usb jacks. One if mine broke clean off when I first disconnected it. (cold solder joint? the whole area looks quite matte and rough)

What kind of oscillators are people using?  I see different types (TXCO, MXCO etc) different min/max voltages and capacitance.  I also can't find one the same size.  Do the 5x3.2mm ones fit?  Are the package pinouts standard?

I was thinking the people who are having problems (e.g. BE not working, very little increase with a 16MHz oscillator) could have one of these specs wrong.  Can the people who have done the mod post specs or links and whether theirs are working as expected?

I think you misunderstood him.

Thanks for the clear tutorial for RPi - would have saved me a lot of time if I knew about it before!  I will check out Arch but I've actually been using stock Raspian with my CM1s and have no problems at all.

Unfortunately though due to this "unless you give us free hardware" policy I can no longer use cgminer with my CM1s so have had to switch camps to the BFGminer which remains open and cooperative with any hardware manufacturer.  I understand that you want to test hardware directly but many people have offered to debug, provide you whatever info you need, and even provide remote access to systems with miners - yet it seems you actually just want free hardware  If that's your commercial model, then I get it - just wish I knew upfront before buying into cgminer.

CGMiner used to work like a dream, then they rewrote the USB stack and broke it (but is much more efficient for those it works for) - and now won't fix it because nobody gave kano a free CM1.  Cautionary tale  - other miners are available  ;-)

Yeah, considered that once. But the vaccum packers are not exactly cheap (like $1000), you can't get them at your store around the corner, and lastly I dropped the idea since it looked like an overkill for packing ~50 bags. In retrospect, it might turn out to have been a good investment...

But.... if it is a research project you can check out my work here...

At least at the end of it you will have a scrap board that has a significant amount of memory, PSU's and a PCI interface...

I was hoping to get them in reels and be able to cut them easily in smaller portions. With the 26x10 QFN48 trays they are delivered in, distribution becomes difficult. I tried hard to get empty reels to split them in smaller chunks, but could not find a distributor for low volumes. Now I'll have to ship them in small ESD bags - like I did with the samples.

Yes, that's right. I was using a cable to avoid stressing the PICKit3 connector/board. To make good contact you have to press quite hard, for about 6 seconds, or it will indicate an error. Holes for pins would have been easier but I did not want to have thru-holes exposed to the heat sink on board bottom, and it needs to be fast enough for production so soldering pins by hand takes more time.

For mass programming I think some kind of lever with the header pins attached in the correct positioning and board reference guides on each side, would allow quickly sliding a board in pressing down, and pushing a button. I don't know if anyone will take the extra effort to set that up but there are various hand operated press type tools around that could be adapted.

When I make my own PnP machine some day I'll put a programming pin header on it so the parts placement and flashing can be automated in one step.

The connector area is cut away . On the projected view you see the radius on the inner edge, that is needed to avoid additional side operation on CNC mill

It appears I have a v1.5 control board.  There is no USB hub.  USB cable goes directly from control board to router.

Have you read and understood my OP? I stated at least 10 times in this thread to NOT use MtGox or any other services that use addresses you do not control (i.e. can not sign with). The has to be the same address where the chips were paid from, coins will go back to sender (that's why it is important to control the address). You need to sign your request to prevent false claims.

Does this help?

Buy backs and Refunds
I have currently more folks interested in buying more chips than those asking to get them refunded. Therefore I am opening a limited buy-back window for all of you who changed their minds. The current demand is for ~4k more chips, so here is the process how to get your coins back:

• PM me your refund request with
  
  • a single CVS formatted line: ; <-N>; <-C>;
    Note:
    
    • this is the exact same line you bought your chips with, but now with negative number of chips N and negative number of coins C
    • all or nothing - no partial refunds, i.e. if you bough 100 chips with one particular order, you can't get only 60 chips refunded
  • a signature of that line signed with

for me personally, package arrived without any customs, fees or another costs. (4 boards, central Europe, DHL) - great.)

I am planning to repair it myself. This is why I bought it in the first place.

Does anyone know if there are SMT "three pin headers" available?
These (and the PCIe-power connector) are the only through-hole parts, which I will try to avoid (to put the board on one big heatsink). If not, I'll use wires to daisy-chain, or "SMT-bent" pins or something.

How can you fix these shorts with an soldering iron?
