Hi
I bought one. Order: #1064

How can I pay with BTC?
Juan please make this 51 units. I paid for 3 already. Yes I have few units more anyway May 23 00:00 EST I have to close the group to be sure we have time to finish all the administrative processes on time to avoid delays. email sent - interested in 1 or two units shipped to Ontario, Canada |

is it just me, or does it seem like there's something wrong with the sticker on the bottom? was it not put on perfectly, been handles, etc?
sticker looks normal, the laser-etched webbing can sometimes have a weird appearance. so long as its continuous theres no issue |

will buy it 0.05
ill give this 12hrs to see if anyone is interested in a higher bid. Then i will PM you. |

I sell a board for that supply http://www.gigampz.com/ we are out of stock but expect more in next week. I have two of these - nice build quality - simple but effective |

Well I can't explain the next diff jump. I mean every ASIC on the market ROIs very very hard. Even S1. So who keeps adding power?
Might be ASIC companies that couldn't sell their gear like Spoondolies. Maybe even Black Arrow started mining with their X3. Some S2 were sold, some S1 and some SP-10 but they don't account for the upcoming 14-18% jump.
asicminer chips are just now getting out into the wild - its likely some of these companies are premining with the chips and/or building private farms before they focus on public sales (hashratio.com for example, which seems to have mimicked the S1 design, but can probably achieve 300-400GH in the same power/footprint |

If your interested in selling this how much for shipping in the US?
i am shipping from canada, so it would be about $6 by regular post with a little padding. |

In my opinion it is just bad luck\timing on your part. It's no surprise that miners loose value quickly, in order to be competitive you need to be able to respond to competition. I don't think Bitmain ever gave money back, just coupons to entice you to order more product. Perhaps Spoondoolies will do the same. Have you asked them?
when bitmain dropped prices from ~0.87 to ~0.65 overnight due to an obvious disparity between good and bad pricing, they issued coupons for 0.2BTC to the affected buyers from the prior 2-3 days. that said, caveat emptor. you knew the price and paid it. |

Anyone interested in setting up a not-for-profit data center for miners in the Montreal area?
The reason for Montreal is cheap electricity prices.
The goal will be to have a space where miners can co-locate at cost. Every miner will be responsible for their own electricity costs. Common expenses such as rent will be split based on space usage.
I am definitely interested - but be warned that it will take significant startup money/power use to make it viable. Expect the costs of rent/oversight/internet/cooling/power to average about $0.22/kWh for a ~30kW power draw and about $0.175/kWh for a 50kW power draw. How did you calculate $0.22/kWh? I know that 10 kWh running 24/7 costs $683 + HST in Montreal. That's about 9c per kwh. Data center colocation costs are quite a bit higher. a bit of price estimation. location (500-900sqft) : $1200 internet + other monthly costs: $100 overhead budget (maintenance, small fee for operator): $200 $1500/30kW = $50/kW/month = $0.07/kWhPower = ~ $0.14/kWh when drawing such large quantities Cooling = +10% with minimal AC, +40% with closed-circuit AC = $0.015-$0.05/kWhif you are trying to cut all costs as low as possible, with tremendous amount of airflow through the building to keep venting heat (especially in summer), you are looking at: $0.14 + $0.015 + $0.07 = $0.225/kWhlocating in Quebec you could shave off about $0.05-0.07/kWh from power and cooling costs. I am visiting a small location in Toronto later this week that used to be used for a body/paint shop and presumably has a significant number of 8" vents and exhaust piping. If all goes well I might be able to offer some hosting there for a reasonable price in the $0.22-0.26/kWh range depending whether the heat could be managed with little/no use of an AC |

What's the function of the tiny fan on the front just below the LCD?
probably to coolthe PSU cables if anything - its not really pointed anywhere critical but at the PSU. (it might also balance the airflow that the psu exhausts) |

Needs shipping to UK and escrow
i still have the ring, and am willing to sell it for that price - i am fine with escrow (at your cost) but also have history on this site of successful sales (incl. casascius coins) without it. shipping is extra 0.01BTC though |

No need to shill. It's clearly a carrier issue. All pictures show the case itself bent. Unless you think they manufactured a bent case, the package had to be hit with enough force to go through box, padding and still be hard enough to bend a metal case.  this - that is more damage than what an upside-down/sideways shipping box would ever cause. that said, bitmain obviously needs to step up the standards a little bit if there are such rampant reports of damaged miners in shipment. there is an very easy way to know if the miner and its packaging will survive transit (and prove it to your customers): Pack it up, tape the box shut, and then roll it off the top step of a large staircase. Do this on video and then film the unboxing. If the unit is banged up and cards came loose you have an issue, since UPS will treat it no better than you just did. I'm 100% serious - really give the shipping box a hard shove so it gets some bounce. You have no idea how badly UPS and other couriers handle 'fragile' items. If the packaging is done right the unit should survive courier. Seriously? How bad do you think it is? How many S2's have they shipped vs the number of damaged miners recieved? Do you have the numbers, do we even know the scope of the number of shipped S2's? I imagine its a pretty big number. I only ordered one personally, and it arrived problem free and has been running stable at 1100GH (overclocked) for weeks. But this thread is evidence that there are lots of units getting banged up, moreso by poor courier handling then poor workmanship. this means a better box/foam is needed generally, and i bet a lot of issues would be avoided |

Is there any easy way to modify files for this (the two asic-freq files and crontab) on all my miners simultaneously?
Simultaneously not, but there is faster way then edit everything again and again. You can copy files directly from one antminer to another. For example: scp /etc/config/asic-freq-high 192.168.something.something:/etc/config I imagine I would do this from the SSH (putty) instance on the machine that i have modified already? ie: scp /etc/config/asic-freq-high 192.168.1.201:/etc/config
scp /etc/config/asic-freq-low 192.168.1.201:/etc/config
scp crontab 192.168.1.201:/ I imagine that it the crontab copy method will not work like this though? is it possible to do something like this to have it operate to all IP addresses with antminer units (and is a user/pass not needed for each?)?: scp /etc/config/asic-freq-high 192.168.1.201-192.168.1.220:/etc/config
scp /etc/config/asic-freq-low 192.168.1.201-192.168.1.220:/etc/config
scp crontab 192.168.1.201-192.168.1.220:/ |

Rough numbers!
By dropping your 200Gh down to 115Gh for the 6hrs (11am-5pm) saves $0.32 day or $9.60 mth in electric costs BUT you lose 0.001225BTC per day worth ~$0.55 or $16.50 mth with BTC at $450.00
Is it worth it?
IMO, not *yet*. I plan to undervolt starting late next month unless the BTC/USD ratio keeps climbing. |

When this will stop? 0.10BTC per miner? Maybe 0.05 more?
Probably when shipping costs meet or exceed any profit margin. That's the official EOL imho. It probably wont go under $75 usd shipping the S1 alone costs them about $50 |

Earning are off, I immediate dialed into that. Also the rejects are fantasy land. GG

Check out the number of sig figs too. oh god, you are right. 10 decimal points. lets just call them centoshis? |

2 files : asic-freq-high with high clock. asic-freq-low with low clock # reduce frequency at noon (00:00 default shanghai time)
0 0 * * 1-5 cd /etc/config && cp asic-freq-low asic-freq && reboot
# increase frequency at 5pm (05:00 default shanghai time)
0 5 * * 1-5 cd /etc/config && cp asic-freq-high asic-freq && reboot
thank you  I just set this up on one of my miners to run noon->5pm at lower speed to see how it works out. if all goes well this would pair nicely with a voltage mod to use the least power when TOU is $0.12/kwh and maximum speeds when it is only $0.07/kwh Is there any easy way to modify files for this (the two asic-freq files and crontab) on all my miners simultaneously? |

Any chance of getting updated pictures? The OP shows invalid image?
Thanks
fixed - guess the uploaded link died after a certain time period. |

little bit of digging and my above post should be possible, but i need input from someone a bit more practiced in UNIX/cron step 1: SSH and login (root/root) step 2: type "crontab -e" step 3: create this pair of new entries: # reduce frequency at noon (00:00 default shanghai time)
0 0 * * 1-5 /vi /etc/config/asic-freq *specify line of code to edit* *reboot*
# increase frequency at 5pm (05:00 default shanghai time)
0 5 * * 1-5 /vi /etc/config/asic-freq *specify line of code to edit* *reboot*
cron reads itself every minute so this should work fine. My biggest issue is I have no idea how to gracefully merge the commands of editing specific lines in the asic-freq file and rebooting the miner afterwards |
