If I were to run one of these, and get at least 8GH/s from it, and I joined a pool - how many bitcoins would I be looking at? A few pennies a day? A dollar a day? I know it's hard to guess accurately, but I'd like a rough estimate. Also, how exactly would I go about increasing it's hashing power to 16GH/s or more?
I'll give you an idea on this: on kano.is, with my 180GH/s i got about 50c a day or 0.001btc. so if you divide that by 10, so 18GH/s, that would make it approx. 5c/day, or 0.0001btc, divide that by half again, so its 9GH/s that's 2.5c/day or 0.00005btc/day.. so about 1/200 days you might RoI.. |

heh, everyone pipes up once you mentioned 5TH unit.. to rich(probably more then what i can fish up in a day, and ~1.5KW to much for my electricity bill) for my usage though..
Since you said the card inside the system would be standard USB, sound like I could buy up 1 or 2 of them cards and run them standalone. 120mm by 120/240mm card would be nice, could just strap 2 large fans to it no problem. if its a 120mm2 board, could even encase it inside an old PSU chassis, or CD drive..
None the less, your projects, I'll wait and see how things turn out.

need more advertisement? mentioned on other forums? reddit even? I think its the chicken/egg scenario, yes, you had the demos out, but since they are not available to obtain yet, people are sitting back and waiting.
on the otherhand, wishlist (waiting on my next paycheck), 20 more to buy up, get them on ebay or something (or just strap to every computer I have here..)

ignoring all the red flags... 0.6 W/GH - Ingenious Power Efficency
C'mon now. That wasn't efficient last year, let alone now. Common man! you want a $2300 room heater that looks like some old macpro painted black and a screen attached! doing a little googling, this company seems to be coming out thick and fast as a mud volcano, and everyone is calling them a scam, they have been around a little doing cloudmining and resale, but their prices are to far off to be legit. |

If anyone is interested in this "technology", this is a little spiel on his thoughts about it. http://thememoryguy.com/micronintel-3d-xpoint-raises-more-questions-than-answers/on the other hand Intel and Micron unveil 3D Xpoint™ technology and create the first new memory category in more than 25 years. [Citation needed]Over the last 25 years there has been many memory types been developed (eg:CBRAM, SONOS, RRAM, Racetrack memory, NRAM, Millipede memory and FJG) by not only intel, but basically all major memory companies, eg, Hynix, Sandisk, Corsair, etc.. now I thought this might of been a processor development (some quantum quadrant bit process) that may have just thrown Any calculation process to the dirt, Thank goodness I was wrong! i think the only thing that could throw the asic's for a 6 would be quantum processing. |

At least that one has one with a coloured cable band on it to show it is for power and the other one is data. The other linked one does not and i have a sneaking suspicion it may have both as data throughput, so one HAS to be connected to only power output! |

All this talk here about fab'ing some GPL'ed Bitcoin calculation cores onto silicon, is it wrong to think maybe making a new post about making a Bitcoin calculation core from scratch? Basically what I want to know is how a core works, what is required to make a core do its job, then go from there, making a prototype core (discrete logic), making a software version of it (programmable logic) etc, etc. I'm probably using the wrong words for this, but I know what I mean  |

A pool goes for a week without finding a block and things must be wrong with the pool itself. Yet, when the pool finds many more blocks than it should, nobody's yelling that something is wrong with the pool.
Too many blocks. There must be something wrong with the pool. yep, time to format the server, reinstall os, maybe do a BIOS update too, could be malware worms in the BIOS, its stealing peoples blocks |

I've paid for the 10, if there is more people popping up, after some in the next week, i'll put in another order for 10 more.
Good job man! Cheers!!! Just have to wait for sidehack now, hasn't been on all day, 'prolly neck deep in fab'ing the sticks |

All this talk about USB2/3, and no one talking about USB Type-C standard? these are the high speed, enough power to charge a laptop, plug it in up-side-down, can hold 5KG on the solder points, super duper end of all connections.. and its also "usb3 standard" with its comms.
One one hand we could just quote the Wikipedia page: USB 1.x and 2.0 500 mA 5 V 2.5 W
USB 2.0 with Type-C 500 mA 5 V 2.5 W
and ask "what's the point of Type-C without USB3?" But on the other hand you have a market segment with money burning in their pockets and literally demanding "go ahead and take my money and rip me off!" I think sidehack mentioned earlier that he isn't interested in "making another toy for hipsters," which I understand and agree. But on the other hand, who's left in this market, beside hipsters with money burning their pockets? [/quote] Well, according to wiki: https://en.wikipedia.org/wiki/USB_Type-CUSB Type-C devices also support power currents of 1.5 A and 3.0 A over the 5 V power bus in addition to baseline 900 mA; But hey, its wiki, and there is no source citing this.. and yes, its has the pins for usb2 differential paired lines. also the differential usb3 TX and RX lines. The only time i use USB3 is when one of my customers have a usb3 port and i can use my usb3 hdd dock to backup their data. imo there is no need for usb3 unless there is big data to move around, you don't see printers or keyboard or mice going into usb3 realms. Still, i think this is getting a little out of hand, i had to poke the fire a little with the usb type-c sick, the way i see it, sidehack/novak does not need to do usb3 support, its the drivers on the system that need to properly work out the usb2 side off the 3 port. |

To clarify - I think I said I didn't want to put a micro on a stick miner but that it'd be necessary for a future [larger multi-chip] miner with integrated digital voltage control, temp sensing and fan speed. I'd rather not stick a 32-bit ARM on something to do a job a 4004 could handle. If in the future we shift to a USB3 interface with good driver support for primitive serial interface and a bundled micro I'd be a fool not to use the micro, but as you said, that's in the future. Yes, USB3 will eventually subsume USB2. But in the meantime we also have a butt-ton of <5W SBCs with USB2 that folks already have and would like to keep using.
My stated opinion - anything I'm working on right now will be USB2 exclusive unless Novak wants that to change. The future is the future and subject to change.
8051/2s are cheap.. all you need is something to manage data and switch between chips, or if they are stringed enough data to give all the chips something to calculate, then push the data back to the host. you're right, you don't need something expensive. Can you even buy a 4004? Now I have something to look up.  Looked it up. Evidently these old CPU's have become collector's items Selling for as much as $1,000 each. Had I only known. thats if you're buying the genuine Intel branded thing (i wonder when the old fable 80286-12 is going that way, i own a working system with one them) .. but you could get in-bedded type cheaply enough.. ATtiny should do the data push/pull easy enough |

Sadly, I just had a SP20 die after a power outage, so that's 1.45T less from here  I'm working on it now, but it doesn't look promising. I can get it to SD boot, but only inside an air conditioned environment. As soon as I put it next to the other miners (~30C) it will not boot. That sucks. Try clocking it lower. It may work. I had an ASIC I had to disable on a SP20E recently. Lots of issues cropping up with these little miners lately. So much for the "professional" and "carrier grade" designations... they are all about a year old now, for something pumping at 100% most of the time, i expect it to go pop, laptops, even business class don't last any more then 1.5 years. if you were close to my shop, i'd ask to look at it and maybe clean the heatsinks and reseat them, see if that would help.. I'm always amazed at how biased people's understanding truly is. A pool goes for a week without finding a block and things must be wrong with the pool itself. Yet, when the pool finds many more blocks than it should, nobody's yelling that something is wrong with the pool.
does people yell at a car that takes them to work? or do they yell at them when the battery goes flat when they try and start it? people celebrate when things go right and work good, and anger when it doesn't. none the less, its all about trying to find a usable pattern in a world of chaotic noise. just to find a nonce in a doubled sha256 "block" once its been found and confirmed, new block gets generated.. Hell, you could do this calculation on pen&paper if you want, 0.05hashes/minute if you're good at math. |

I wonder how hard it'd be to integrate level shifting for string comms?...
didn't newrbox do this this? ..wait, or was it just multiplexing? dang it, i don't have one in front of me, i could look up that silly chip.. (there is a little dual lead flat pack just down and to the side of the controller, next to it is a few resistors in a little network on a mount for another one of them chips. there is 2 of these, one set is also below the fan headers). |

Bit of disclosure (as I've stated before that I only intend to get 2 from GekkoScience direct): I'm in for 1 (one) via AJRGale's group buy for a receiver in Australia, txid in PM.
Updated, Thanks. |

Well, Wednesday 6AM (Sydney time) sales open on the Compacs. As per https://bitcointalk.org/index.php?topic=1126705.0sidehack is quota queueing, we pay, its manufactured and shipped. If you want to pay for them now, and wait it out, BTC Address is: 17z2no9upjzgqjYfuG2Z72Ezyg4KEmeq53 Just PM me with your TX and your details. Or you can wait for them to be shipped to me to pay for it, so I post them out to you. Also, Escrow is your responsibility, I'm happy if you want to escrow, but you are to take up the escrow fees. So far, there is 10 on order, that is $35aud, and $25 postage from sidehack's workshop, totalling $375aud (or rounded to 1BTC because I cant be bothered with the little numbers ) to sidehack. Also, I have set myself a limit of 50 stick (unless otherwise stated). |

Why not both?..
Well, you're right, we don't need the extra com ports, or multi power rails for redundancy/load balancing.. Its the customers fault that it catches fire, they turned the voltage up that 1mV to high Regarding other chip makers
Yeah, fare enough, spondoolie i expected to be a lot of work to even get one chunk o' silicon to get running. just looking at pictures of the layout looks insane! looks to be 6/8 rails going into one chip? and then cooling the 100w odd chip.. i would like to see your run of the "bitcoin Dice," but the r&d would take some time And avalon would be a fun little chip to play with, would be nice to see if you could improve over their "Avalon nano v2" As for the pick-and-place, I can say "we bought a pick-and place" but I can't actually say "we have a pick-and-place" quite yet.
Well, that sucks some, get into a F100, go to the shipping yard, borrow their forklift, load up and go! or say "Screw you Guy! my money back Now!" ether way someones head should roll over it :| Also, AJRGale, I got an engine-shaped miner sketch for you but apparently the scanner doesn't like me.
well show that scanner who the boss is! i wanna see this entertainment! |

Except for the watercooling part (and double-sided chips), the thing you just described is pretty similar to the thing I was thinking about last night.
well, i was going overboard with it, i've never seen watercooling for longevity, even engines needs a good flush and waterpump change after 100,000kms (or 5 years of driving). so simple watercooling for electric components, running a waterpump and fluids for 24/7, just seems like a job to take care of every 3 months. but hey, you know you want to go overboard With the exception of the large chip purchase (which, recall, was partially funded by community loans), the total budget for the project so far, which has produced a single-chip test board, a dual-chip test board capable of parallel or string, an 18-chip base string board (with no integrated power or control, but all node-level and inter-node requirements met) and prototypes of two revisions of the stickminer, has been less than $1000. We can work pretty lean, which we do because there ain't a lot of money.
That said, we don't have a lot of interest in getting money from a venture capitalist. Maybe if I already had a demonstrably working final product and only needed money for production, but didn't want to coordinate a group preorder that size (which is riskier) we'd talk about it.
I'm pretty sure I can finish out a BM1384-based functional 18-chip and 30-chip board (as planned), probably also with a functional 4-chip pod as a dev step on the way, for about another thousand bucks. If by the time I have that working someone's gotten us samples of a chip worth playing with, it shouldn't be difficult to retool for the new chip. If we go Bitmain, likely the protocols would be basically the same so the only requirement would be redoing footprints and routing, maybe adjusting power systems a bit. Avalon uses a similar primitive IO with a different control structure, which means new footprint, swapping the IO chip and redoing drivers. In either case it wouldn't be difficult. I'm willing to risk a thousand bucks and work time over the next month to finish the BM1384 project on the assumption that I'll be able to get new-gen chips and end up with the best miner money can buy, and then I'll be able to get someone with money to buy it.
Joys of being small and flexible dev team. Large companies would look at what you're doing and may copy, if not they'll just ignore you. im almost tempted to say there are some people with many bitcoins and their thumb stuck up their butts wouldn't even care, they would be content with a warehouse full of dense miners.. but im not in the best mind frame to say that... One thing that's going to help people ride out the halving is getting a miner well beforehand that can run profitably at top clock, and can also run both profitably and longevitously at lower clocks afterward. A fixed-operating-point miner like the S5 couldn't do it. My TypeZero is designed specifically to meet that need. If it behaves how I think it'll behave, the top-end efficiency should be a few percent less than the best-case with a string miner, but the bottom-end efficiency should be a few percent better than a typical re-voltable miner, and that it can make all those adjustments in software isn't terribly common. Spondoolies does it, sure, but I'm pretty sure my boards will do it better - more efficiently and a whole lot cheaper.
Being able to build a good chip would be pretty great, but we've zero VHDL experience and don't know anyone capable. If the community, or someone friendly to the community, can pull off a chip I'm more than willing to help wherever I can.
all i can say is i'm content with my 160GH/s pulling 170W and only getting 0.0003btc a day, so im not the type to whinge about getting my return investment. the way i see it, don't skimp out on making a miner cheap so people RoI, make it so it doesn't catch fire after 3 months of use. laugh at me with this, but the U3 is built better then the NRB, for starters, it has 3 other ways to talk to the chips if something goes wrong. (rs232, i2c, and direct chip coms). i do have a question, have you talked to the other 2 chip fabs? avalon and Guy/spondoolie? if all else fails, would it hurt to retool to one of them? If not, im happy to start a Open source bitcoin ASIC core (i've basically watch a few hours of people explaining Verilog, that thats my grasp of hardware description language, all i could do is start the movement) Margins on the Compac aren't amazing but if we end up selling all 1000 sticks there'll be more money available than is required to finish out the project. One thing that helps cut costs is "vertical integration" - we were able to scrape up enough for a pick-and-place and decent oven so we'll be doing all the assembly at almost zero cost instead of hiring out at probably several dollars per stick. It also helps timelines because we can work 20-hour days to get stuff done if we need to (the week I fetched 31 Tubes for hosting customers I worked 110 hours and slept about 20 in six days, and Novak has many similar stories) and most hirees wouldn't be willing to do stuff like that for free.
I think chips in September and having a product by Christmas is certainly doable.
Well done getting the P&P+Oven, the sweet smell of cooking solder, why do you want to sleep though that? Also - Bitmain did respond to email overnight. No chips to sell at the moment, but they may let me know if anything comes up. I'm not terribly optimistic but that's certainly better than nothing.
that it is, but i think his PR department should be sacked, they suck! holy hell, i opened this to reply at about 11pm, it is now 12:40am.. need more beer |

i just had a baaaad idea, v8 shaped container, the daughter boards in between the head and blocks, daughter boards have dual sided chips, massive cables, for power/data, hid inside the "exhaust" tubes, using the block and heads to allow water, Yes, Water cooling over the chips, and a 120mm/140mm fan strapped to the same sized radiator. At the back of the "v8" is control board with gauges/led light bars/ with throttle control etc à la Conley Precision Engines  |
