Do you remember the S1?
Shipping from stock, not from farm...
No pre-orders....
No delays....
the blessed auctions? pretty sure i got units from the first and/or second auction that paid for themselves and resold at good value for S3 |

man this all got out of hand quick. yeah, i agree that in a large installation a battery backup is not really necessary unless you have some reason to believe that your power may be intermittant/inadequate and having even a 20-60 second backup battery to prevent needing a full restart (can take a minute or two) or otherwise affecting the chips via thermal changes (unlikely, but still has some effect on the overall product life)
Anyways, seems like a whole lot of speculating and waiting for a reveal

"Ready to accept SP50's, I assume they should be off the assembly line." Well that answers some of our questions: SP50s are actively being produced, the pictures weren't renderings, queue up now for hash rate. I just see a bunch of empty racks and transformers. Who knows if they are anywhere near close to production. you dont drop several hundred thousand (maybe a million+?) on racks, cooling, and transformers unless you have a near-term plan to use them (and BTCS=SP-Tech, so be sure they are gonna be the first) http://www.emersonnetworkpower.com/en-CA/Products/ACPower/LargeFacilityUPS/Pages/LiebertSeries610OnLineUPS1001000kVA.aspxthats what they have in the second hall, 225kVa (208V i presume) UPS systems. Point me to any other mining facility (besides legit datacenters/colocations) that use these to prevent electrical downtime okay after a bit of extra searching it seems emerson offers both 225KVA UPS and 225KVA PDU. I was a bit hasty in my googling, but i imagine this is the *correct* PDU: http://www.emersonnetworkpower.com/documentation/en-us/products/acpower/powerdistribution/documents/sl-20045.pdfIt offers the benefits of acting as a transformer, fuse panel, and PDU all within a single unit. fewer cables and devices, better efficiency, and no battery. that said, having a UPS (or even a capacitor-based backup) would be useful in areas where theres a risk of power fluctuations or 'blips' that could otherwise disrupt operations or cause reboots in the miners. The number of times ive corrupted SD cards in an RPi due to a 'flicker' (even in an office building) is insane, and some devices cant handle fluctuations very well |

Australia and China actually(Type I). After looking into it further, it seems that China also uses a type A and C, so it could be type A without a wider neutral pin like we have in the US. I'm not sure if this means an R1 with Type A plug wouldn't fit snugly in a US outlet. I guess we'll have to wait to find out.
http://www.stayonline.com/reference-international-plugs.aspxif you scroll down you'll see that the common chinese 2P is exremely similar to the north american NEMA 5-15, with the difference being a fraction of a millimeter dimensions-wise. The China GB1002 and GB2099 standard 2 pin 15 amp non-grounded appear to be physically identical to the NEMA 1-15 found in North America. In many cases a North American plug will mate with China receptacles without an adapter. However, the China standard holds to tighter dimensional measurements than those in North America. This means that in some cases North American plugs will not quite fit into China receptacles. tldr; chinese 2P is slightly smaller, and will fit most north american outlets, possibly with a bit of wiggleroom (so be sure it wont slip out of the outlet) |

This is gotta be one of the sexiest mining pictures ever. For sure! Good I idea though using the heat form the miner to help the plants out. Very interesting can I ask where (country/state) this is in? Never thought of the two mixing thanks for sharing. my guess is in north america with a medical card or grower license. The plants look nice and healthy, probably 3-4oz/ea if they are put into flowering soon only thing that confuses me, is what the temperature of the plants was already? I grew in a similar vinyl tent years and years ago, with my lighting in a ducted glass tube t draw the heat out of the tent (typically 30C exhaust, with 20-25C in the tent and 15-20C outside) It seemed like heat removal was way more important than adding heat |

I repeat, the only real photo of the backside of the unit is this: looks like a US plug tucked away there at the side...why do we need an extra usa adapter for $1 usd then?  It looks like a pair of fold-away metal prongs. BLADED prongs, parallel to eachother. Bitmain's own pictures of the front show slight dips in the case where prongs would likely fold away. It seems safe to say there are built to fit a typical US outlet format, without grounding (common for most small electronics). whatever, i ordered 2 of them anyways  |

Why would it be 800W? Posted chip specs are 0.14, not 0.2
The S5 can push upward of 500W without chipside heatsinks.
The S1 was 350-400W originally. The S5 uses the same heatsinks so we know more heat is possible. 5 chips is more like a small pod miner than an S1 blade.
oops, you're totally right, S1 could handle 400W in that case would love to see 2.5TH that i can use with an S1 frame and not worry about excessive noise |

A picture of my modest mining facility  It may look like a mess, but everything runs like a charm and is properly identified! so thats where you've been putting the 16awg PCIe cables I sell you |

We've done preorders for two products so far, the first batch of DPS2000 PSU boards and the first batch of Compacs. The DPS2000 boards started shipping I think 7 days behind schedule, but the PCBs arrived from the etch house 9 days late (2 days after our product's ship date). The Compac started shipping 10 days late, but the pick-and-place arrived about 50 days late (seven days after our product's ship date) and the heatsinks arrived 14 days late (three days after ship date).
I don't like taking in money on things I can't deliver immediately or awful close to it. But sometimes it's necessary to get enough cash in hand to buy parts for a full batch.
The problem I'm running into right now is having enough money to fund the development process. I really don't want to take on debt for that. Hopefully I can get everything working in short enough time and when sales on 750W PSUs and Compacs are doing good that we aren't put in a bind.
Also, the rough numbers we're looking at right now would put an S1-sized miner at 28 chips, about 4TH topend.
4TH, or ~800W? sounds like that could be slightly tricky on an S1 (which was 180-220W originally) without secondary heatsinks for the PCB. I was expecting 4-5 chips/board (500+GH) and 2 boards/S1. |

clipped image
its a good question. I actually beleive that you do not need the adapter. look at it: clipped image It looks like it adds a grounding pin, but otherwise serves no purpose (that grounding effect wont transfer to the R1 AFAIK) Is it just me? That plug does not look like it fits that adaptor. It looks like the 2 pins on the R1 flip out (like a lot of wall-wart devices do) and completely compatible with the typical 2-pronged (L,N) 110-120V sockets in North America. The adapter looks to simply convert that to include a grounding pin as per 3-pin (L,N,G) outlets. Only reason you would otherwise use it is if it features a 115->230V converter (which i doubt) |

I bought 6 of them.
There is already 4 of them sold.
I will have 2 to sell.
If you want some let me know.
Not sure what adapter ew need for the unit. I just saw a picture of the device in the Hardware thread. It doesn't look to be a regular power adaptor but more like an Apple power supply device or router. Double metal header that you have to slide in to switch from US to EU but i'm not sure. looks like a US plug tucked away there at the side...why do we need an extra usa adapter for $1 usd then? its a good question.

I went ahead and ordered two, without plug adapters.
Might just sell the 2nd one locally (Toronto/Vaughan) or via ebay

I would love to see bitmain produce a mining bitcoin node, possibly with the same router capability

Sign me up for one, if shipping to toronto can be done <$10
I guess this could be hard since the stick compac cost me more than that to ship. Dont think I would be able to ship the R1 for that price. no worries, at that point it almost just makes sense to buy 2-3 of the R1 myself since the shared UPS shipping drops to $8-10/ea |

Well it increases the hashrate of the network and makes it just a bit more secure
but I find it a funny idea and it helps securing the network...
No, this thing absolutely does NOT "increase the hashrate of the network" by any measurable amount, nor does it do anything to "secure" the network. Are you guy just repeating buzz words or what? This is like the agrument that "one vote doesn't count so why vote".. Sure 1 repeater is next to nothing, 100 000 repeaters though... HOWEVER, due to the fact it's tied to ant pool the extra security to the network depends on bitmain not wanting to launch a 51% attack... I cannot see why they would do that. 100,000 repeaters (~$2,900,000) is still half the hashrate of a single SP50 (~$45,000 estimated price) it does slightly help the network, but the amount is absolutely trivial and furthermore if it is fixed to antpool then you are actually only helping out someone who already controls nearly 20% of the hashrate |

I certainly hope so, otherwise this thing is totally useless and a gimmick.
And knowing Bitmain their fork of cgminer on the R1 will have crap messed up in it and it won't be efficient as it could be and Kano will have to write an updated R1 version...
Totally useless? I think that is quite the overreach, if it can give ethernet only devices (Many miners) connection to a wifi signal, power a phone or pi and mine I think is worth the extra 10$ over a tplink that I use just to connect a miner to wifi. So you have "thing A" that does the exact same thing as "thing B", except "thing A" costs more to purchase, and costs more to operate (because of the ASIC), and both "things" have basically the same chance of solving a solo block (0 for "thing B", essentially 0 for "thing A" and getting closer to 0 with every + diff adjustment)? I am failing to see where I overreached here. You probably thought the bitfury lightbulb had merit, too. its a novelty, but its ideal for a future where someone who doesnt know how to easily buy bitcoin can have a small wifi router that gives them small lottery odds. personally, i want it to be pool-customizable. The above scenario works way better when the user can instead make a few cents a day for use in online tipping or micropayments but mostly, its a novelty thing. It pairs perfectly with the U3 as a cute "look im mining bitcoins!" doohicky and otherwise would look nice added to the stack of old/collectible antminer hardware |

I'll be legitimately surprised if the SP50 comes in under $50K each. Buying 22x S7 to get the same hashrate would cost you over $40K, plus PSUs, plus the premium of having about 40% lower power consumption and, if it's like everything else SP has ever released, undervoltability (but this is very questionable given the released specs). $50-60k seems about right, which puts the 1MW cost around $3M.
don't forget that you are also paying for 22xcontrollers ($~40/ea?), about 38 extra fans (44 vs 6 IIRC)(~$10/ea), and other costs related to the case, pcie sockets, more heatsink weight, larger individual shipping boxes (probably costs $500 more to ship those S7 units then to ship a single SP50). The Sp50 shaves around $2000 in costs by being a singular device with only one controller. Enough to make up for the 10x power supplies almost. Add in the "bulk" aspect, and i would assume $40-45k also: i would put at least 10BTC towards a well-orchestrated GB with colocation at GND. I would risk more, but I believe holding BTC>$400 might be a better investment |
