The latest pool performance is completely dope, i joined at the 666.666% block and since then overall we've had sick luck. Who made a pact with the Devil? *Eye people around suspiciously*;  I mean you got to notice the irony. We get a 666.6666% block and then we get the devil's luck. Oh well, well done pool. |

Discussion on the rackable unit was coming down to figuring out how best to stack seven or eight of the S1-sized board and heatsink combo in a 4U and allow for both external power cabling and internal interchangeable server PSUs in the 1Ux2U scale.
Sandwiching a PCB between two heatsinks is going to have a problem of now you're limited to a single-sided board with no components taller than your ASICs, or you have to mill out channels in your heatsinks or use individual stick-on chipsinks. In any case it's not really something I look forward to requiring. My goal for the TypeZero board is a max power dissipation around 320W, stock settings probably more like 250W or under, and able to run off an unmodified S1 chassis. Might need outside panels like the S3's housing or S5 provide but that's not really difficult.
I don't really want to build something like the S7. Power density may be great for folks whose costs go by the square or cubic foot, but it sucks for anyone trying to keep a rig quiet and stable and those are more likely my target customers.
Ah, yeah i can see the problem with that idea. And I don't personally mind the space efficiency that much, for my own devive i was thinking more of it creating an ease of airflow direction to dump it outside, since imo, home mining is all about cheap electricity and no cooling cost. If the air flow straightforwardly like pretty much any of the Antminers, its easier to dump. Since the miner itself push air, you just need to have the exhaust already outside your place when it exit the miner. I guess its probably best come to that "problem" when we have some specs out. |

I'm actually impressed, that make it super simple and super modular. How do you cut the plastic? With a wood saw? And where do you get those... "Egg Crates" for cheap? Then you just tie wrap the miner stuff and maybe hot glue or screw the plastic in place.
Right now i just put my stick on the hub and put it on the side so that the USB fan sticking out from the mobo blow air on it.
Egg crate is made of stiff polystyrene plastic, so it's easy to cut. I typically use diagonal cutters. The plastic easily splits along the cut line. Very easy to work with. Got the idea to use this stuff from a very different hobby (salt water aquariums). I bought a big panel a couple of years ago and have built out three small scale rigs out of the stuff. Usually I just tack down the power supplies, hubs, etc. with zip ties. Once the components are in place, the rig is effectively portable. It's typically used as paneling for lighting fixtures, especially comercial fluorescents, in the US at least. Any building supply or lighting company should have it for pretty cheap. If you search for "egg crate plastic" you'll find a ton of options. Thank you, this is great, i found this; http://www.homedepot.ca/product/egg-crate-white-louver-2375-inch-x-4775-inch/924867Its like 10$USD for 24*48inch~ thats a ton of material and its hella cheap. I'll have to pick some up next time i got the car. I will definitively use this as base from now own instead of the convoluted stuff i came up with for my GPU rig. And on top you can have air from go through. Great find! With this i might even be able to afix the Sidehack stick to my GPU rig that has a box fan blowing air between the GPUs. Wont need to use the USB Fan. |

The pod board would not be designed for S1 compatibility. They'd be two separate PCBs.
If we get far enough into pod to make it viable, I've been needing to talk to a couple people that shipped me a few cases of Freezer 7 coolers last year for about fifty Technobit Minion boards that never got shipped. The coolers are still sitting in boxes on my hosting shelves, been there over 13 months by now. I could look into buying them off the guys and making that an optional sale alongside a pod PCB.
I think four chip is going to be easiest to wrangle, which leaves a 500GH top-end for the pod. I say top-end but until I get some actual chip data beyond the one operating datapoint Spondoolies has on the SP50 product page I don't really know. Could be higher, could be lower, but I don't want to build more than about 100W into it. A decent air cooler should be good for 100W. That might mean five chips but I don't have enough info yet so we're talking over various configurations of four chips. I've talked to Novak about building it to sell in the $200 range, so a 1BTC price point I'm preliminarily confident is doable.
I'm not too much on package design, but if someone wants to volunteer to help, I can share mechanical specs as they get ironed out.
If I build something bigger than the S1 scale, it'll probably be something along the lines of the rack machine that was being discussed in another thread, using seven or eight of the same boards. I'm not sure my little shop is up to the task of designing and manufacturing a whole product line of electronics quite yet, but a pod and the TypeZero board in various configurations should meet most needs between 50W and about 2500W. I don't feel like competing in the 1200W Jet Turbine or 17KW Shipanchor market sectors.
Sound good to me, i hope more people follow the thread and decide to at least mention their interests in the project. I didn't see the stackable rack you mentioned but basically, if you make a small PCB and then lay a heatsink and then sandwich the heatsink between another PCB and another and another, you could probably just use a quiet but bigger form factor fan to push air between the PCB's, a bit like the S7 design, it could allow interesting scaling and efficient space usage. It would also make directed airflow easier any maybe even use vinyl tubing to take the final exhaust outside or something. And i hope you don't try to compete in the 1200W+ range, a smaller stackable/compact/space-wise unit of any kind that you can easily fit physically and electrically, that is quiet and relatively cost efficient sound like a great niche to work in. |

The hard part to is I get around 8gh when I run normal. Once I run OC i will get around 16gh(some have shown 20 I have not gotten that high yet but it's possible). So you can get 2x as much from running hot. I think that is still fair as it's a compac.
It would be easy for someone to game the system. But if we suspect anyone of doing it we can easily ask for picture of sticks. Hopefully no one will do it as it would ruin their rep. Also I am hoping this club is a long term thing. Chances of hitting a block are slim so hopefully we get to know everyone within the club as I hope it turns into a social aspect.
That would be nice, we could have a sub thread with a list of users with proof picture, maybe, i guess its not important to think about it for now. The club could get pretty big if most users that get a stick decide to join, since i think the total amount of sticks will be 1000~? But i expect it to stay relatively small since i doubt that many user know or wish to keep track of this now instead of just do the lottery on their own with no one to answer to. |

I measured it at 0.5A, so 6 Watts. This was by measuring with 2 hash boards Connected & then with 1 Hash Board connected. The difference is the current that a single hash board is taking. Multiply by 2 and take it from the number you first thought of  & the have the Controller current. Someone else measured it at between 8 & 11.2 Watts. So it somewhere around there. Rich Gotcha, based on your electrical knowledge and seeing how much power is available to the board, are you able to extrapolate how much juice it can give to fans without blowing up? It's pretty obvious that Bitmain will eventually release an "S7+" - already did most of the engineering for it between the S7 and the S5+.
Has anyone actually tried running an S5 hash board on an S7 controller yet, or a S7 hashboard on an S5/S5+ controller?
Now that there are quite a few S7's out there it would be good to have an answer to this question? Rich Yes. Biggest S5, which is been made.  Click to enlargeS5 BBB with S5+ software, S7 base plate with 9 long data cables. That put my 2xS5 project to shame. So thats with a S5+ controller? I would very much like detailed pictures of this, any thoughts on starting a thread and showing off everything? For the long cable, i'm still waiting on Jabberwock to get back to my PM, i will definitively need a couple. If you know another source, i'd be interested to know. |

I would probably just hold. The 21 bitcoin computer seems to new and not tested yet, most cloud mining operations are scams nowadays. So the safest way would be to just hold.
Yes, hold. And i don't think the 21's "Bitcoin Computer" is necessarily a scam, its just that its application and use is very questionable and sound gimmicky, just like the Antminer R1 aka Antminer Router. And neither option sound particularly ROIable so i'd get another S4 for that price long before i would buy either of those first two option. I'm not super keen with option 3 either but its probably the best in the choices given. I never said that the 21 bitcoin computer was a scam, I only said that the 21 bitcoin computer might be to new not tested yet by users. If someone would consider to buy one should wait until trusted people could review it and post their thoughts on it. Sure and i should of said "Vaporware-y, unclear, shady, or gimmicky at that time." i didn't mean to call you out. The notion of that 21 Bitcoin computer is just extremely vague and its function isin't even properly addressed, so i'm not even sure its about waiting for trusted user to vet it, its just about knowing what the hell its supposed to do. |

hi, has any one still have S7 batch2 coupon ?  if you have these, i want to buy 3 S7. so i need 3 coupon  my id : Turgan also i will publish S4 efficiency & chain problem solution pdf soon. thanks... Well there's no "Batch 2" coupon, the coupon all expire on 12th of October. If batch 2 hit by then, then i have one to sell to you at market price, 0.1BTC, feel free to take it to my thread or in PM; https://bitcointalk.org/index.php?topic=1194780.msg12538795#msg12538795 |

Didn't they catch the guy? And wasnt some insider worker revealed all of it? I just figured by now if it was true, Karpeles would of confessed by now? I have to admit i didn't entertain the thought the guy could be innocent but if it wasnt a scam, why did he run with millions of dollars in BTC?
He hasn't confessed to anything. He strikes me as so far moved from reality he probably wouldn't give up anything after decades of exacting torture. He's being charged with embezzling $2.6 million of customer funds. As for those hundreds of thousands of coins, that remains a mystery. http://www.coindesk.com/mt-gox-ceo-claims-to-be-victim-in-bitcoin-exchange-demise/Thats crazy and i think the biggest damage it did to Bitcoin isint all that capital but all the FUD about how Bitcoin is for criminals, untrustworthy and stuff. Half the people i met in life that heard of Bitcoin replied stuff like. "Yeah i don't buy in that BTC stuff, its shady as hell" or "What? The thing criminal use to transfer and launder money?" ;_; But i guess if i was him, and betting on BTC in the future and i had 1.whatever million BTC stashed somewhere, i would also just do the few years in prison and then be covered by the stature of limitation. A few years doesn't sound so bad when you think you might be billionaire if BTC rise, by the time you get out. Whats a few years of lazing around, being fed and lodged behind bars, to 50 years afterward of gluttony? |

Right now I'm more likely to get SPTech chips than I am BM1384, and given they're not talking to me about BM1385 either I doubt that'll happen. If I come out with anything it'll be new chips from someone and be capable of operating in the 0.15-0.25W/GH neighborhood. I'm not competing with the S5 - it's old news. I won't, and can't, compete with used hardware prices on new hardware with new chips a year old. If Bitmain and SP stay in the 80dB consumer and 17000W industrial products, it seems likely the "niche market" of people who want to be able to run miners like they've had access to for the two and a half years before right now will be wide open.
If Bitmain doesn't release a S7 mini, Bitfury continue being picky about who they sell their stuff to and SP just keep building bigger and bigger ASIC, then i very much hope you can get those SP chips to make something custom. (Or get a very big crane to move those silly SP units >.>) I don't intend for you to specifically compete at the S5 level, if you compete at the SP50/S7 level, thats a okay too, we might be looking at the need for 0.37$/GH + or less 5 cents at current values, and thats a-ok. Bitfury also allegedly have 0.06W/GH iirc? If you had some 4-5 chip pod that did 600-750GH/s for 0.2W/GH i would gladly fork something around one BTC for one and i'd probably take a couple per month. Assuming we can find a cost efficient quiet-ish Heatsink to slap on that, i'm sure many others wouldnt mind loosing their pockets a bit. A nice feature the community could come up for such miner would be it fitting in a stackable plastic frame maybe? Then you have their fan pull the air into the heatsink, outward, in one direction ish for easier dumping of hot air. Or whatever. |

My 4 Compcac "Cube".
Thanks for sharing! Very cool use of the old block erupter cube. I have been playing wit the Y usb still some to get more speed. I need to find a nice way to let them sit infront of the fan's. Looks very nice with usb direct on hub but y cable means I need a new design. I'm a big fan of egg crate for smaller rigs. It's not pretty, but it's super versatile. Here's what my stick rig with Y cables looks like (repurposed from running a bunch of DualMiners recently):  I'm actually impressed, that make it super simple and super modular. How do you cut the plastic? With a wood saw? And where do you get those... "Egg Crates" for cheap? Then you just tie wrap the miner stuff and maybe hot glue or screw the plastic in place. Right now i just put my stick on the hub and put it on the side so that the USB fan sticking out from the mobo blow air on it. |

A majority of the posts here are like that and have been for a long time. From what I can tell this is perfectly fine here so nothing will be done. You are allowed to post only to get paid here so long as you make it over a few words. Useless walls of text are also fine so long as they are somewhat on topic and not just a copy/paste from elsewhere. I am sure that guy probably has several accounts to farm the campaigns with.
This is very disappointing. I do not think his posts are adding anything to any of the conversations and can be generally be described as useless. The fact that he was making one post every 106.05 seconds, on average should be fairly solid evidence that he was not even reading the threads he was posting on. I agree with you, but thats the way it is around here. As long as "low post quality" is okay for the campaign he signed in, then he's clear. He's not breaking bylaws and he's absolutely not the only one. Like i just said, more than half the posts in Bitcoin Discussion is like that. Pages and pages of nonsense, so i don't blame legit people doing discussion from skipping the pages by the dozens. The topics are much more rich in hardware, market and support threads. Not really, a lot of people get banned for low quality posting, even if they are not spamming but i agree that some of the campaign managers are a little bit too, well they are not doing their job correctly. Ban from what? The campaign? Because according to the forum rules, low quality posting isint spam/flooding. If the campaign manager are supposed to be kicking users with bad quality posts from their campaign, then i would gladly like they start tightening the screw. There's some pretty interesting topic i'd like to actually discuss but my posts are stuck between a flood of different meaningless posts. |

Bit-x too paying once in a week at monday by a bot  and somewhat yobit signature too paying daily. Refer their thread i think that the bit-x campaign is full and has been for a while, they do have the best rates on the forum so it wouldn't surprise me, but i am not 100% sure :/ The Bit-X campaign is still open! Nice timing for the sale pitch.
As long as you don't rely on the payout to be always very accurate, its probably the best signature campaign(?).
Yes. It's very, very well run compared to others and they always come through eventually. And i very much hope so the campaign will continue for a long time. In my situation of being in-between positions with stuff going on, this is pretty good money that i can put in hours very versatility, so it could pretty much make the difference to get the best outcome. |

It is really difficult to say, I arguably think that the MT.GOX incident was the biggest scam that happened to bitcoin. Many people lost thousands of bitcoin and it damaged the reputation of bitcoin itself.
Pretty sure its factually MtGox? But personally i would say PayCoin for how long they/he managed to control all those people by the nose, that continued giving him money over and over and over until he was long gone on some nice tropical island sipping his martini. (Biased as hell) Well you can argue that MT.GOX was a scam. Some will say that the actually got hacked and some will say that karpeles did it on purpose. Didn't they catch the guy? And wasnt some insider worker revealed all of it? I just figured by now if it was true, Karpeles would of confessed by now? I have to admit i didn't entertain the thought the guy could be innocent but if it wasnt a scam, why did he run with millions of dollars in BTC? |

Donation vs sticks matters in that only the 'sticks' actually partake (at least in this round) should this club hit a block, the donation ones are just that, donation. Mostly up to phil - I really wouldn't mind a fixed forum post (e.g. the first post), if phil's most comfortable with that.. should be able to get the bot to parse it out, at least as long as it's somewhat consistent (again, e.g. "philipma1957s7" isn't clear if that's a stick or donation, from a bot's perspective - could assume anything that isn't 'stick' is donation, but then there's e.g. "kipper01") - json is cleaner, but might not exactly be second nature to him will try to get a sorted neat list out on the top page want to be loose and easy the first 30 days so you can donate and get a share. we are 11-26 15 days in. OK. We'll keep things simple and as-is for now. We can figure something out that works for everyone once we're on the other side of the 30 days. In the meantime, I'll give this some more thought. But I'm back to thinking that a shared dropbox link of an unformatted text file is the simplest approach. It's easy to share the file for editing. And following redirects in Python is no problem, so the notification script can easily read a dropbox file. Under the hood, I might use a list like this myself just to make it easier to update my instance of the notification script. I can share the link with TheRealSteve if he's interested. Anyway, we can return to this when the time is right... In the meantime, I finally got my Y connectors and time to use them. Yesterday I doubled the output of my 2 sticks to a whopping 33.8 GH/s! Yea it looks like they can OC from 8 pretty nicely. I'm still working on my setup to OC them. The only thing I think for sure we should keep is base hash power on sticks not donation if we ever did hit a block. I'm not sure how to do it fairly but donation count to somehow. As it's awesome of Phil to do so much donation hash. Just don't want it where big hashing machines crush the stick ratio. One S3 even is a lot of sticks. Again none of this matters till after first 30 day's. Having multiple stick entry would be kind of trouble some. Tho rewarding for people, unlike me, who have gotten multiple sticks. Already of course, a user could make multiple entries with other sticks since we weren't required to prove the uniqueness of our sticks, but if you let people just say "Oh yeah those 120 gh? Totally 20 sticks" while its just a underclocked S1 for instance... xD People will eventually catch on to both how to hack the system and us who cheat but iunno. I always assume people will come that have ill intentions. Another system regardless of what we do in the future would be to do a verification of trusted owner with a pic and your name with a TXID, the TXID being there to prevent a user from making a pic with the same sticks over and over for his alts. |

The Bit-x payouts can be a bit cranky. My original payment slot was on a Tuesday. Due to multiple delays that's now slithered across to Sunday morning. They always pay out but it can be a little hit and miss. I think it's often something to do with the blockchain.info API.
Happened to me this week, shifted from Wednesday 6 to Friday 3. It was a bit odd because i was overpaid as if post made between that time frame did count, but only if i remove about 10% of the overall payment. I was shorted 10% the week before again so it could be possible, but its hard to say now or pretty much impossible because of the shift. Now with the limit removed i'll have to take note of my posts counts and make screen shot to not forget. But it's not too bad because sooner or later, Marco comes through and give you the dosh. As long as you don't rely on the payout to be always very accurate, its probably the best signature campaign(?). |

I wish I had the bollox to gamble with 12BTC for one day.  Ugh i feel icky inside just thinking about gambling all that BTC. Though I aknowledge that is not a lot of money to everyone and many gamble with a much grander magnitude pile of cash... but still, damn. However statistically if you keep repeating this in favorable conditions, the laws of average would dictate that you would win by x% overall, so this could be an investment if you have a big enough roll over... or a strait gamble if you don't. |

Great guide Dogie..
I really like your comprehensive check list you made that depict which feature the miner has or not. I really hope you keep using that in all your review/guides from now on.
Anyhow, my biggest worry about getting an S7 is the noise. I'm surprised that beast only does 61dB at max fan. Is that actual reading with a sound meter or a reading taking from the manufacturer's fan taken in a sound proof room?
The S5 is noisier and with double the TDP for the same formfactor-ish i can't imagine the S7 being any quieter.
