1  Economy / Service Announcements / Re: BITMAIN's website and online store are open-promotion with limited 30 AntMiner on: January 11, 2014, 07:52:43 PM
Looks like they have reached the 30 valid orders - the page is now showing 'Sold Out'.

My order just switched to 'Paied' as well Roll Eyes - pretty much right after the 6th confirmation came in. Since they seem to be waiting for all 6 confirmations the 60 minute limit is indeed quite tight. So far I have not received a (payment) confirmation email either.

It looks like they have already received payments for quite a few more than 30 orders, closer to 60. Payments are immediately forwarded to this address:

I am wondering if the website is not enforcing the 30 unit limit, or if 30 or so of these payments are not considered to have been received in time (and will be refunded?).

So, I've read thru the comm. specs and we're golden. All looks like it will work ok, and is pretty darn close to expectations.

I'd optimized out one RES line and will have to put it back in as the data is encoded across both lines. ...

It looks like there is a absolute timing dependency between the DATA_P and DATA_N signals, are you sure that you will be able to interpret the data correctly with the PIC controller? Is there are way in a PIC controller to get a timing relationship between two captured serial streams?
4  Bitcoin / Development & Technical Discussion / Looking for test data on: May 13, 2013, 07:05:42 PM
Does anybody have any test data for regression testing optimizations for a hasher implementation? Something like the inpute state on one side and then all valid nonce values, if there are any, that yield a valid solution, preferrably for a low difficulty?

I know I have a whole blockchain with thousands of test cases on my disk, but maybe somebody has already gone through this parsing exercise to create some nicely formatted test cases?

Thanks in advance for any feedback.

It looks like the hash chip sends back the report data asynchronously. Is a PIC controller capable of concurrently clocking in results from multiple chips?
It's a wired OR bus, all outputs join together into one PIC input. The PIC does have a UART and amazingly I just hooked REPORT_P to that pin. Smiley Smiley What's even better is it has IOC (interrupt on change) so I don't have to poll it.
Are you assuming only one chip will report data at a time (i.e. data is never being sent concurrently by more than one chip)? I have a feeling all chips will report some kind of status not just when a good nounce was found. But I guess we won't know for sure until the communication protocol is released.

The result data gets back from the ASIC to the PIC via a secondary route as serial data. It is only a 4 byte nonce (I believe), and so is a very small amount to return back to the USB host.

According to other posts regarding this topic, assuming the sync is completely stuck even after shutdown and restart, the database files may have become corrupted. Other folks have recommended starting from scratch, after saving the wallet.dat of course, assuming you have already have some BTC in your wallet:

In the bottom right corner - does it show active connections to the Bitcoin network?

So you are gambling with $150+ for a coin flip (50% odds, your intended bet), accepting a $150+ loss for potentially turning it into $300?

Sorry, but that kind of cost/benefit ratio is not very appealing to me ...

It's the same as betting it on blackjack.

Well, for a $150 bet I want at least a free drink - then I would call it fun again  Wink

As far as I observed the processing is not done in a single step, so even after the 'Processing ...' message for a block has disappeared the 'Your BTC reward' value will change for a while. The first value shown is always something really small and then it increases until the reward computation for all shares is complete.
