Well, that's shameful. My impression was that Bitmain was the most reputable asic company out there. I was shocked that Yoshi would even tell me that my miner was working when it clearly wasn't - like somehow he was going to convince me otherwise. Eager now to see what comes out of 21 Inc.
I posted a link to this thread in the main S5 thread. If it gets deleted, I'll repost this thread over there.
Thank you!

It really does look like downward trend is causing less hash:

Bitcoin Difficulty:    47,427,554,951
Estimated Next Difficulty:    46,444,875,248 (-2.07%)
Adjust time:    After 612 Blocks, About 4.4 days

Very interesting I wonder how many miners are turning on/off with difficulty changes.

Currently a little under 270 on price.

When my Antminer C1's get old, I plan to use them to heat the swimming pool water.

So someone working on the wiki just asked for BM1384 pictures. Guess I'll have to do that tomorrow then. Also I think we have enough info to start work on a test single-chip board to start getting software ironed out. After that it's only a few stages to a test string/matrix and a working full design. Tomorrow will be a miner day (tentatively named the TypeZero) but after that I'll have to get back to the inline regulator project (tentatively named the Chuckwagon) because the prototype's been overdue for weeks because of various "this doesn't work, what the heck", "where did our R&D budget go" and "being really busy sucks" type problems. But progress is being made.

One of these days I'll start an actual dev thread for the TypeZero, and one of these days I'll have a Chuckwagon prototype for Philipma to play with. Only been promising him one since about Christmas.

But if what we want to do is possible (and affordable, and we get enough money to actually make a batch) we'd be looking at what amounts to an S1 Upgrade kit to the tune of 1.3TH <600W, which can software-underclock/volt (using cgminer flags) to a 600GH ~160W miner. Or the boards can be run individually as ~300GH 150W units clockable down to 150GH <50W and run off a brick, which if you add a quiet 120mm fan could make a pretty decent Jalapeno-formfactor desk miner. Boards would be USB-connected to a controller, so each "S1" would require a 4-port hub but several should run off one host (Pi or whatever). That's the goal, anyway.

If we were able to pull it off, how many folks would be interested in a Prisma chassis refit? I'd shoot for the same power draw (~1KW) at stock settings, so if it scaled directly with the current idea's expected limits you'd have a range from 2.4TH@1KW to 1.1TH@300W.

I think you might be right. The spreadsheet is now showing the estimated difficulty to be -1.92%, although the 3 day moving average is lower at -3.71%

If this drop is being caused by the DDOS attacks, then I am surprised that it is lasting this long, although it could be that pools that were being used by a large corporate farm(s) were affected, and all their miners were effectively kicked offline and for whatever reason were never brought back online.

I would say that if I do not end up winning then the contest will likely roll over because the difficulty will probably decline by more then what I predicted.

If they're rating them at 550W, you could get away with 2x on each Evga 1300W G2. There isn't really a non server PSU, sensible option to run 3 of these.

That linked to there out of stock hell have to buy them off of  newegg or the other place i linked.

Somebody please point me in the right direction.

I have 3 - Antminer S3's and want to power them with Evga-Supernova-1300-G2 which did not come with evga cables.

Someone please provide me with a link to amazon or ebay or newegg for the proper power cables that I need.  I already bought a set
that will not fit because it has the "mini" 6 pin connector on one end.  Seems like most of the power cables I see are the wrong sex.  Anyway, this has to be simple for someone who regularly uses antminers.

Thanks in advance.

I bought one of these from a Chinese reseller on Alibaba.  The power supply died and I can't find a replacement anywhere.  The P/S has no 24 pin connector.  Just a 8-pin to the PCB and then 6 6-pin connectors to the mining boards.  Now that selling miners is hard my reseller stopped offering them and won't respond to me.  I need to buy a replacement power supply jst like the one in the picture.  Can anyone point me in the right direction?

I want to invest in mining, And I want your advice :

1- Would I buy this product or not :
...

And if the answer is no, How would you advise me about other products.


2- Or invested in mining Cloud.(And any companies advise me , and why)

Thank you 

Yeah that's what the rational side of my brain thought at first but then I thought it would be nice to break through $300 and keep the difficulty down.

It might happen, maybe if we see a 2nd wave of DDOS attacks  

Bitcoin Difficulty:    47,427,554,951
Estimated Next Difficulty:    47,508,999,644 (+0.17%)
Adjust time:    After 820 Blocks, About 5.7 days

And BTC around 290.  Looking like another nice difficulty jump so far.

And that is one of the great things about mining community being so big.  I know at around 10 cents I decided to get rid of S3+'s before summer heat.  But with cheap and "free" there is a market for them still.  And the S3's are built pretty rock solid.
