Sorry if I'm asking in the wrong thread but here it goes:
Are there any significant differences between batches #1 and #2? any expected for #3?
Batch 2 units cost $140 more, after you account for shipping. Batch 2 units "might" have 6 module slots instead of 4, but would still ship with only 3 modules initially installed. A different payment processor is used for each batch. |

Probably. I imagine the restart will be the easy part. Detecting the failure condition programmatically will be the harder part.
Of course not ... my API has all sorts of information that will show the condition ... and if the API isn't working, you take that to mean the condition exists also. Of course there are updates to the API but ... Cool. I'm not too familiar with it. Is it JSONRPC just like bitcoind? Care to give a cookbook query string to get the current hashrate? |

Any idea what kind of DHL delivery they're using? Express or otherwise? And what are they declared as? What was the origin point, Beijing?
DHL Worldwide Express. Declared as Industrial Controller (engineering sample). Shipment appears to originate in Hong Kong, though the return address on the invoice shows a Beijing address. |

I encountered the fan/temp bug again this morning. I noticed it cycled the fans on maximum speed for about 200ms, and when I checked the cgminer status page again the temp and fanspeed readings showed non-sane values that varied rapidly and were sometimes negative.
It also stopped hashing. I presume as a safety measure.
I let it go like this for about 3 minutes this time to see if it would recover. It cycled the fans onto maximum for 200ms a few more times, but never did.
When I restarted cgminer via System --> Startup in the web UI, it then mined normally again and showed normal sensor values.
is there a way to automate the cgminer restart? Probably. I imagine the restart will be the easy part. Detecting the failure condition programmatically will be the harder part. |

Anyone have such high HW errors? What does this indicate?
[Getworks] => 1963
[Accepted] => 27062
[Rejected] => 963
[Hardware Errors] => 866
[Utility] => 30.57
[Discarded] => 3649
I did when I was overclocking with --avalon-options 115200:24:10:45:300 Changing to --avalon-options 115200:24:10:42:300 cleared it up for me (thanks to luffy for suggesting it). Supposedly the fourth parameter is a "controller timeout". I'm not sure why reducing it helps. |

About that WiFi antenna.... can I connect by a normal ethernet cable without using WiFi ?
Yup, there's an RJ45 on the back. That's how mine is connected. I never even attached the antenna. |

Physical copper? Wouldn't you'd have to buy loads of the stuff to stack up much significant value?
1 short ton looks like it would be about $7000 today, if I'm reading things right.

Sctyh3 wanted to buy mine for $10k, but I decided I'd rather keep it.
$10k I would take that 10K and buy a stack load more then again $10k for the unit will bew made in a few weeks time lol I thought of that, but there's a lot of risk involved. I would have to wait for batch 3 to order again, and who knows when that will open. At the rate things are moving along it could be a while. By the time batch 3 delivery rolls around, the landscape could look very different. A few months is a long time in Bitcoin land. Then there's the question of even being able to get an order into batch 3. The way the previous 2 batch sales have gone, I wouldn't want to count on it. |
