I'm willing to bet that in the fine print the 'within 24hrs' is after it clears their orders system and shows up in your account orders as 'paid'.

My b3 took a full 28hrs before I got the Paid email from them. Based on the Paid email date/time technically it took another 26-30hrs before I got the Shipped email but they got it close enough for me.

Now as to the Scenic route that UPS decided to send it on which added another day. Plus the import fees kerfuffle...

I tried using OPE (over Powerline Ethernet) to run a link from my house to garage using TPlink's latest modules. Worked great until the garage got to ~95F. Then they dropped the connection to each other. Odd thing is the lights on them are merrily blinking away like there is traffic but the miner beeping says otherwise.... Have to unplug it for a minute then plug back in,modules find each other and all is well until temp gets too high again.

Even the one in the house runs rather warm so add a hot environment and the dice are tossed.

Hmmm... So when did AntPool start looking at Eth and LTC??? https://www.antpool.com/home.htm

Your proposal is far outside my interests so I'm out.

Hmm. Still, looking at the next nodes makes sense and now is the time to start playing with ideas that could take advantage of what those noes could offer. Emphasis on 'could'.

That is then followed by when will the 10/7nm nodes be viable for mass production of ANY chip? My crystal ball says, "Not for a minimum of 3 years away".

The single problem with mono heatsinks as usually done (on the back of a board) is one of thermal transfer. If a chips is dissipating more than 10-15w then great care has to be taken regarding thermal vias and contact bumps on the board/heat sink interface to make sure enough heat can flow from the chip through the board/vias to the sinks. Even if done properly a naked chip is still going to run a fair bit hotter than one with a topside heat sink which in turn will directly set what the maximum speed/Vcore can be.

Now maybe if the chips can be mounted on one side of the board and all other components in the other to allow a single large heatsink contacting the tops of the chips-- that could work as it takes the boards thermal resistance right out of the picture.

Normaly, at most an hour or so. But - my last order for a b3 when they were available again took just under 24hrs to show up on the Bitmain site. It too had previously been marked as unpaid/unshipped..

That would be one way to look at it. The complexity and circuit density of the process so far is dictating that the dies will be fairly large/high value. IMO probably because they can fit so much into the dies that the cost to connect simple circuits to the outside world makes them a moot point. ref the threads here a while ago about IBM announcing a 7nm test chip https://bitcointalk.org/index.php?topic=1508382.msg15196056#msg15196056 and https://bitcointalk.org/index.php?topic=1508382.msg15197990#msg15197990

<facepalm>
14nm ain't gonna happen from Bitmain as that process is available only from Samsung or GloFo foundries. 12 or 10nm chips of any sort will not be available from anyone for several more years, on top of that, so far looks like <12nm is going to be reserved for high complexity chips and not simple boutique ones like mining ASIC's.

Don't have a dog in this fight but, do keep in mind that Innosilicon is first and foremost an ASIC design company. Not just a mining ASIC maker. Their main business goes far beyond coin miners and that is why no mining farms. http://www.innosilicon.com/html/about/about-us/

Yes. All of it.

This is not about building an ecosystem or changing the world, it is simply about building a miner based around the best suggestions/ideas presented here. Nor are the plans for said miner to be mass produced per se which removes the need for most of the Corporate overhead you call for.

I mean, "design , prototype, test and deploy cycles under quality control and management supervision"? The final design is not up to a vote, it is up to the head of the project, Sidehack. Period.

Folks behind this thread have seen previous hardware projects fail and fall apart precisely because of the design-by-committee approach and worse yet -- direct investor input/pressure from folks with little to no skills on the technical matters they are pushing their wants/idea for -- that you are advocating. For one example, WASP is a great Poster Child for that. It's end result was endless discussions over minutia, continual scope-creep and tons of wasted time and monies all of which finally drowned the project in bureaucracy and killed it.

I for one am all for the Lone Ranger (cowboy) approach. Then again, like Sidehack I am one as well (though my biz is industrial lasers).

Now, does Genius need backers to fund building/testing/implementing their ideas? Sure. I for one am grateful to have hooked up with one back in the 70's when I was at Photon Sources, he was their head of aftermarket sales. We soon left together to form our own company and have not once looked back ever since. He was also wise enough to let me do what I do so well with zero interference while he concentrated on sales of what I come up with and build, running the business, and finding capital to fund the R&D toys, er, equipment I need.

Well put. The only flaw I see is:
    "This could be managed using GPIO to activate/deactivate relays that feed power to the hashing boards."

Relays that can handle the currents involved are not cheap. However, use the same idea but talk to the MC to trip the voltage regulators run/stop pin just like a PC's PWR_OK line from ATX and other psu's so the Vcore regulator(s) simple shut down until all is well again..

Since early 2014 I gotten around 80 miners in total from Bitmain, this make only the 4th time I had to pay.

So, methinks something in the Customs rules deciding business (fees) or personal might have changed. Or, their monitoring/tracking software is now looking at how many/total value of goods you get in a month or so.

The IRS does the same regarding the banks having to report deposits over $10k. They now track it on a per-month basis and if a business it making a lot of deposits just under 10k the Feds get -- interested shall we say, and start talking to each other. In Michigan alone there have been several arrests and property/money seizures of folks running rural small business like a hardware store. Later thrown out of court but - good luck getting property/money back. t is often held for ages as 'possible money laundering evidence'.

Query: How is the miner connected to the home network?
Hardwire only using jacks and cat5 cables?

Any chance for a WiFi option as well as the hardware (for setup) connection?

Hmm, might also be a good chance to reuse the WiFi boards and hardware from s1's... I ask because it seems the OPL LAN bridge between house and garage is acting up again -- it runs warm to start and doesn't seem to like a hot garage So, need to setup a WiFi link from my home router to there... Side note to this is that my s7b6 normally draws 1090w as reported by the UPS feeding it, when in loss of internet 'safe' mode power drops to 390w. So far fans always stay running at my set 85% but if they ever stop....

For the new miner - how about the MC having a safe mode to have the V regulators feeding the ASICS to shut down when the network connection is dropped and the ASIC's are just twiddling their thumbs?
 
Along those lines, Why did Bitmain change drop using OpenWRT? I loved the data traffic graphing it offered.

Yeah, I coulda. Even brought my checkbook yesterday when it was supposed to show up before UPS decided it should take the scenic route. But it dinna show in the morning so I used their phone ccard payment. Nice agent btw. Anywho, just said screw it and them figure it out by Monday.

Only real significant bitch is that I was going to take my last 4 s5's at work offline to send to Sidehack for his Compacs and replace with the s9 still coming out ahead by >6th with 1/2 the power use.

Mine sort of did...
UPS showed up at work to drop it off but... It was still tagged as COD for the customs/brokerage fee despite me paying UPS with a CCard around noon on Thursday.

I have the receipt and UPS clearance conf# but he said since their delivery system hasn't released it yet if it clears he'll be back around our normal pickups time to drop it off, if not, should be Monday.

5:00p came and went, no miner 
WTF is wrong with UPS's accounting systems?

Mineral oil and 3M's Novec fluids are totally different things. The higher viscosity and much poorer thermal transfer properties of mineral oils means that great care has to be taken to ensure enough heat is pulled fast enough from the chips. With 3M's thermal xfr fluids, they are thinner than water so flow very well (rather like butane in a lighter) and more to the point, when in the phase-change range (boiling) heat xfr ability goes through the roof because the fluid in contact with the heat source wants very much to stay at the phase-change temp.

That said, oil is still a tempting idea.

Gotta love how Bitmain made the extruded cases to be able to lock together in a row or in cubes for easy handling
On the s7b1, mine has been simple great! It's been OC'd ever since I got it to run at 700MHz and according to Kano holds average of 5.3THs with common Pk of 5.7 to > 6THs. Astounding. I have a b5 running the same. The other s7's seem already near max performance at stock speed and do not take well to OC. Oh well. After I do the Sidehack under-volting/clocking of them won't matter.

Damnnit... I paid UPS yesterday for fees owed, truck came today with the miner on it and -- driver said it was COD. Showed him the receipt and UPS conf# and doesn't matter 'cause the system still has not been updated for it...

Hopefully by time of the days-end pickup it will have cleared so I can get it today vs Monday.  Grrrrr..........

First, how I do my filter/siren killers:



Most of my main Ant colony heat removal. I'm using a 12"  true ventilator blower with flex ducting https://www.globalindustrial.com/p/hvac/fans/blower/portable-ventilation-fan-12-inch-with-16-feet-flexible-ducting to move the heat from the (upstairs) room out to the main production floor.

Gotta say that despite having 18.2kw worth of s7's up there, so far max temps in that area have only hit 85F. Not bad at all.








83 cubic meters/min = 2931.117 CFM
Best thing is that being made for use with ducting CFM does not suffer to much. Cost $190.70 inc shipping.
