Can't really say.
In one mining area I have 8x s5's running between mid-50's up to 63C with most in high 50's and right underneath them are 6x s7's running 52 up to 65 mostly around the same high 50's.

I'm impressed...
Aside from the delay caused by CNY, Bitmain replaced my dead s7b8 hasboard exactly 7 days after they got it. I waited until the 18th to send it, UPS shows it received on Feb 22 and I just got the replacement today. Different board, slightly older rev but what the hay, that's what is expected for warranty replacements. It works fine and now that s7 is up to full speed for the 1st time.
Also have to add that after I sent the dead board I got no further word from Bitmain about it's status much less the replacement being on its way...
According to the RMA information it can take up to 1 month so needless to say,Congrats on the fast service.

<snip> Bitfury already has a more efficient chip available 0.1 j/GH http://bitfury.com/products I do like that containerized 16PH mining system they offer ... now only if I could build a nuclear power plant in my back yard ... Overkill. Just need a more convenient 3kHP diesel generator... |

Excuse the noob question, but does the S5 controller need to be extracted from a S5, or does it have "extra" hook ups so you can tie into an already mining S5 with your pod?
I would buy one for <$100, put me on the interested list.
Believe it depends on if your controller board has the extra(unused) sockets on it as well as unused fan connectors. Someone else here was selling extra long data cables just for this. Along those lines... do the later ones sans unused connectors still have the board traces so connectors can just be soldered in? (and anyone have a link to those long controller/hashboard data cables?) EDIT: Found it. https://bitcointalk.org/index.php?topic=1173573.msg12359304#msg12359304J4bberwock was doing them for both the s5 and s7's. Ya'd have to PM them to see if any are still avaiable. |

As ya know, I still have more than a few s5's running with 5 hosted by you ... What would the pod or boards hashrate & power be at lowest power setting?
After the Halving think they'd (as pods or retrofits) still at least pay for themselves at your place?

Query: Can a 'real' Beagle be flashed with Bitmains firmware and would it be a drop-in replacement for theirs? Newark/Element14 is having a clearance sale on them right now.
Of course you would still need Bitmain's interface board tho.

Real records (Vinyl) is still a big business with many current artists releasing on Vinyl as well as the usual media and a few have done releases on Vinyl only. Over New Years in New Orleans my GF and I spent $264 at http://www.peachesrecordsandtapes.com/ . There is a lot of new pressings of old albums, from the greats like Led Zeplin, Deep Purple, ect. to just about any genre there is. One record we got was a new pressing of harmonica tunes from the 1920's. A few others records we got is some mighty fine classic Blues  My turntable is a Technics manual direct drive I got in the early 70's, a Heathkit preamp feeding 2 Tigersaurus 250w mono-channel amps I built. http://www.tigersthatroar.com/?page_id=59 System is still in many ways equal to the best you can get even today unless you spend the kind of $$$$ on the stuff posted earlier |

I've seen TSSOP and QFP with belly pads.
Good to learn something new. Makes sense since there is all that otherwise unused real estate under it. |

Since I haven't used the AntMiner PSU before, without adding a switch, the only way to turn it off is to unplug it? Is that correct? Is that the way people without a switch turn theirs off? Since I am not very electrically minded at all, are there some instructions or tutorial somewhere that I could follow to add this switch to the PSU using the green/yellow wires? Thank you so much for any info you can provide! To switch it on/off I just unplug the jumper plug. Yes you can just plug/unplug the main power feeding it but not best way to do it. To add switch to it: Got to hardware store and buy a small simple push or twist single pole switch with wires on it. From the same aisle in the store get some small electrical wire twist caps for 18ga wire. Go home. Remove the jumper from the green/white wire pair. In the middle of it cut the wire loop on the jumper. Carefully strip back about 1/2" of the insulation on the 2 wires. Twist one wire from the switch and one from the jumper together. Twist clockwise. Twist on of the small electrical wire caps. Do same for the remaining switch and jumper wires. Done. |

Bitstream or GTFO....  Now seriously, on your next 16nm chip you need to do two main things, if and only IF you want to dominate the bitcoin mining business: - Sell it on small quantities: 3-packs (no problem with markup here) or even have a sampling program (look at TI's or Microchip's program, you get the drift). TSSOP or
QFNQFP versions would make you my personal heroes, like, really heroic. - Release a GOOD, CLEAR AND INFORMATIVE SPEC. Bit-level timing, SPI commands, application notes with usual circuits for working the chip.
These two points aren't really that hard, and would show your commitment to a real decentralized, hobbyist oriented business. I just want to get my iron, solder and create my own money making machine. Is it that too much to ask? I fully agree on the info release aspect. How do chip makers like TI, Linear Technologies, Intel, BM, et al sell their chips? By putting out data sheets and offering sample lots of chips and eval boards. |

Unless in the future they get the per-chip power needs below ~1 or 2watts at most you can't use TSSOP or QFP packages. I've never seen any used to remove that much heat from a die without slathering their bottoms with compound to let the board pull more heat away. Even then, iffy at best for power chips. QFN package are not only smaller but have the large contact pads to give direct bonding for power feed and heat removal.

I need to find the video of it, but I remember that a university evaluated the difference between static panel vs rotating panel and they determined that the power to rotate the panel is bigger than the power you get from doing it. So not sure if you should go that way. Will try to find the video.  don't see why it would eat much power. Just google 'solar tracker add DIY to that and you will fnd dozens of ways to do it. Simplest is 2 photo cells with a diffuse image of the sun shining them feeding a comparator. When image is centered between the cells the comp is in balance and motors are off. If the image favors 1 cell or the other the motor is powered on to move the right way to center the image. All in all depending what you set the in-balance window to, very little power is expended. The at-dusk/nighttime rewind to morning position is just as easy. |

So, after skimming the thread a little... i only have one question to y'all:
Why the fuck aren't we organizing to get a community chip done?
I know, i know, scary asic costs and such, but does anyone have idea of the process? is anyone informed at all?
PlanetCrypto once suggested on another thread that they could deal with the asic side, if sidehack was willing to build the miners, did this die off? is someone around up to snuff for FPGA to ASIC design?
For a start. perhaps someone here can do an ASIC die layout. If so, Then the real expensive part comes: I don't know first-hand about TSMC but - we work with the #1 chip packaging company in Taiwan - folks that mount the silicon die into the final chip package - and they will not even talk to a customer without a 100k$ up-front minimum to even look at the design & mfg of it. That is just to get past the initial sales meeting and have them evaluate the feasibility of your product with no guarantees of it being viable. If going for 16/14nm node I'd bet TSMC and any other foundry is going to ask for no less to look at producing the dies. Also based solely and explicitly on what you tell them to do they will do it, even if the design itself is wrong or not properly spec'd to the last detail. If you want design suggestions from them regarding your design specs and expectations - that costs extra and you MUST ask for their input. |

'Prolly should say that my extreme conservative approach to pcb layout comes from first making boards using tape on Mylar then cut Rubylith back in the 60's through pretty much the late 80's, virtually all analog from damn near DC through RF. You learn fast to be up on best-practices eg. Be Damn Careful and never assume - verify it. When them durn newfangled PC's showed up and eventually combined with photoset machines for making the layout masks it made correcting problems/errors a lot less painful... Nowadays, just get a 4-board proto run from PcbExpress or whoever and not bad at all to make changes. But Lessons learned stick. My favorite and now deceased columnist who perfectly mirrors my views on the electronics design process http://electronicdesign.com/author/bob-pease Pay special attention on using sims like Spice. eg, how-to and how not-to. His works should be mandatory coverage in any EE program. This is only one side of the coin. But this coin has two sides. I believe that no amount of breadboarding or soldering would lead to things like https://en.wikipedia.org/wiki/Chua%27s_diode, https://en.wikipedia.org/wiki/Chua%27s_circuit and https://en.wikipedia.org/wiki/Memristor . He is also the inventor and namesake of Chua's circuit one of the first and most widely known circuits to exhibit chaotic behavior, and was the first to conceive the theories behind, and postulate the existence of, the memristor. Twenty-seven years after he predicted its existence, a working solid-state memristor was created by a team led by R. Stanley Williams at Hewlett Packard.
But lets be realistic. This is a Bitcoin mining board. Here people who never attempted to plug Type-A USB into Ethernet RJ-45 socket are considered computer experts. Try it, they'll fit and won't break. I challenge you. Since this is the place to be free to wander a bit, No doubt sims/tools are needed these days. However, even running a logic sim through an FPGA does not mean the on-silicon equiv will work right. <holds up picture of the A1> By what the archived A1 Dev site says, Zeffir had it working perfectly on his FPGA rig. Come Inno's first engineering sample chips and bzzzt...Power & freq specs way off. Pease's topic http://electronicdesign.com/analog/what-s-all-spicey-stuff-anyhow-part-25 emphasizes that tools are only as good as the (known or all too often assumed ) data and conditions fed in. They definitely have their need but: Ya know - GIGO. Now is my (conservative) approach overkill? Well for Consumer grade electronics probably so. <yes> We still support several systems I personally built in the late-70's. They still run 24x7x365 making parts for chips and other things in the everyday world around us. So ja, I do overkill a bit... On USB-A/RJ-45... or if <cough> someone is trying to reach around the back of a PC to plug one in. Ya know 4 of them are right around... next to the RJ.... |

During the summer the area those are in gets up to low 90'sF and all is happy there.
Like your setup.
