The bit I don't get is how come the BA team failed so miserably to assemble the miner but two guys in a flat somewhere in Bulgaria can?

Also, I can smell another  communication cockup in the making, you need to have a crystal clear process for telling people how to register what they want to do bob!

yeah bothers me. but  as Long as no more cash leaves my pocket I ill hang in till the end on this.

bob tom and dz have done very well for me on more then 1 occasion.

So after a 3.08% jump does mining look better?

   Some More reasons  mining can become profitable:

 super mining centers may be  a victim of terror , earthquake, fire, flooding.

Too many eggs in a basket run big losses.

We all should remember what happened when WD hdd plant flooded.

Or right now as I type Israel and Gaza are tossing missiles back and forth.

God forbid one drops into the sp30 plant.

Or the next Tsunami hits and floods something in china.

Concentration of large power sucking btc mines is asking for a plant to be destroyed one way or another.

some big mines here at this link are all in 1 spot.  

http://blockchain.info/pools

there is a solo address with 5%

another solo address with 4%

 a third solo address with 1%


this trend will lead to a crash and burn of a big plant  it is just the way things work.

To say BTC mining will never be profitable is silly.  

To say BTC mining may be hard to make a profit is better.

But if you are in position like right now (next jump is 10 or more days) and coins jump overnight to 1200usd  you make a ton of money in the next 10 days or so.



I don't think it was your intention but it sure seems like you're hoping for terror attacks, destructive war and devastating natural disasters to keep bitcoin mining marginally profitable for a few more months.

Maybe I'm a bit to "peace & love" to see death and destruction as a temporary cure to mining woes.

no I rather it all hashes.  But the op chose the never word  . Thus I can list hundreds of ways the never word would be wrong in his example.

Here is a peaceful one  world wide bank interest rates continue to suck.

 Thus a few big  investors decide to pump btc to the moon.

 3 people with about 250 million  each would be able to boost the price to the moon.

Little miners like myself  With 10  coins and a few th mining score nicely when coins go to 6000 usd. 

Sounds like the sept to dec 2013 runup all over again.  coins soared 10 fold.    that certainly make the never in the title pretty wrong.  And no violence
42303  Bitcoin / Hardware / Re: [GUIDE] Undervolt antminer s1 [1.19W/GH at the wall] on: July 13, 2014, 10:41:25 PM
Hello,
this is my first post, I am mining novice in BTC
I got 2 used ants S1 for cheap and I tried the voltmod to ramp up the efficiency. It works, thanks for pointing it out! Great job!  Cool
(I live in germany and power cost is pretty horrible here: ~ 0,27€/kwh // ~ 0,36 in US$)

But I still have a few questions:

1. How do I set the frequency correctly?
option 'freq_value'    '0A81'  #275M <- What does this exactly mean? It changes with chip-freq setting as I have seen in the config.
option 'chip_freq'     '275'  <- Can I adjust it in 1MHz-steps, by simply putting in the desired freq.-value?
option 'timeout'       '45' <- This seems to be just for booting up the ant, until chips are ready?

2. HW issue: The ants show much HW (in my opinion). After running the same time with mod@~0,85V they show the following in the browser interface:
Ant#1: ACC:1381  REJ:3  HW:796 . In stock condition (180GH/s@350MHz) this ant had 0-10 HW even after running for 24h or more.
Ant#2: ACC:1364  REJ:2  HW:2699 . Also in stock condition it had almost double HW of ACC. It got about 4°Celsius hotter than Ant#1
But the pool (BTCGuild) always shows the correct speed for both ants. Now around 140GH/s each. This is calculated by the submitted ACC+REJ shares, right?
Or does the antminer also submit the #HW to the pool?

Info about my rig:
Both ants show the same fanspeed 1920rpm now and temp. 38-40°C. Room is 28°C, I will put my rig in a cooler place when everything is set up. Each blade is wired with 3 1sq-mm (~17AWG) wires for +12V and 3 for GND. Power is provided by 2 strong HP Proliant DPS-800GB (12V 82A each), which also run my ~170W scrypt rig. So I guess power is adequate.


 here is my thread on freq settings


https://bitcointalk.org/index.php?topic=589429.0

here is a you tube


 https://www.youtube.com/watch?v=72FU4Z_n0B4

use both to set at 275 or 300
42304  Bitcoin / Hardware / Re: ANTMINER S3 Discussion and Support Thread. on: July 13, 2014, 07:48:39 PM
Anyone one else a little concerned that Bitmaintech hasn't giving us an update on shipping or updated their support page with S3 info and firmware?

And to anyone who would expose their miners to outside air, keep humidity in mind. I had an old Avalon unit I stuck outside in a screened in porch area. It was away from any rain however, after a couple of months the circuit boards started to build up corrosion and the miner stopped working, until I cleaned the corrosion off. I keep it indoors, in the A/C after that.

the miner will not be exposed to outside air.

 It will blow the exhaust outside .

 the inside will be right under a central ac vent in a spare bedroom.

once I get it set up you will see what I mean.

All the hot warm air will blow out the window.

All of the btc world is waiting for this gear.

Well the delay will make my 1th  dragon miner earn more money.  so I have a silver lining to the clouds.
42306  Bitcoin / Group buys / Re: [Closed]R17x: Black Arrow Prospero X-3 <DZMC Exclusive> $130 / 40GHS on: July 13, 2014, 06:19:36 PM
It looks like we should start seeing X3s next week, possibly the week after.

As is stands right now, R17 has 15 machines left on order, plus 8 compensation machines with PSUs paid for.

That gives us a low end estimate of 38TH over 765 shares left, high end estimate of 50TH [1TH/Module to 1.2TH/Module] ; so 49.67GH per share to 65.35GH per share, minus colocation. This assumes no change to compensation from here on out

Our second option is to convert the 15 units to 1500 chips, and pay 750 to have them assembled into marto74's technobit boards. This would obviously increase the colocation costs, and possibly delay the online-time, depending on when the X3s are delivered. The benefit would be an increase in speed from 38-50TH, to 75TH-86TH. We [Minersource] Will provide all the PSUs needed for the duration of the colocation, but the cost of the heatsinks will need to be paid for out of mining revenue. We are open to both options.
My previous maths was flawed (based on the minion performance when running at 0.5w/GH), I now think the boards are our best bet, but only if we pay for the boards in cash not chips. Is that option still on the table bob? (Obviously I could do it direct, but that 20% discount swings it). Also can you lock the techno guys into a delivery timeframe? It will make no sense unless delivery is guarenteed.

We can pay cash with the 20% discount, (cash being BTC or USD) or with chips it makes no difference to I or Marto. Delivery should be pretty quick, as we have sent a decent number of chips already from minersource chips, and we can use those as a quicker start while we wait for these chips. I will ask marto.

The lack of posts/information has been deliberate, we got tired of posting news after news only to have BA prove it false, and as such declined to post till I had something concrete to offer.

well upping our hash could work but  we can't lose a lot of time.  so much has been lost time wise.

 and my skin in this game is 5 of 765.  I go with the majority whatever it is.


  (btw I am on the wrong pc I am philipma1957)

I go with the flow.  I am back on my other pc and can access my philipma1957 account.

My main concern is no delays.  I would hate to  delay hashing another 10 or 15 days.

 I also don't want to lay out more cash.
42307  Bitcoin / Group buys / Re: [Closed]R17x: Black Arrow Prospero X-3 <DZMC Exclusive> $130 / 40GHS on: July 13, 2014, 04:19:55 PM
Thanks for the round-up, bobsag3, that's great, and for keeping the option open.

1. Had no idea there were so few loyal ba customers left, though some call us chumps.

2. Personally reluctant to go to a fourth party, however competent, and complicate matters.

3. Think we have a better position to wrangle with blackarrow for compensation. They need to be seen to sort out loyal old R17 properly, or do they not?

4. Quite see the contrary arguments too, though would need exact figures for W/Ghs, heatsinks and increased hosting sorry collocation. Someone remind me?

5. Think the 1+T/hs blackarrow modules will be more saleable on ebay (Philip?), and we should get on with selling them off sooner rt later while 1 ths still looks like something to the wider chumpatron.

tl;dr railzand vote hold

We could take the 38th-50th  of built machines.  Since speed helps  and they get here faster. mine them and list one at a time on ebay.  

 trying to add more cash to double the hash would only be an option if it was the exact same time to get it.



 so if we have 23 machines each with 2th mining power  selling them one by one on ebay. as we mine may work out.

in usd fiat 765 x 130 = 99,450  

   a 2tb machine may get 2.5k  and we have 23 of them…  If we list 1 at a time to sell them. we can pull in some coins with the remaining ones mining.

We can only make a usd /fiat profit if coins go way up.  So if we get back 50 cents on the dollar fine just get it over with. If we are mining as fast as we can and selling one by one on ebay.  we could get lucky and coins could jump up in price.  we could then raise the ebay selling price and do better then 50 cents on the dollar.



 As I understand each machine gets 2 modules of 1 to 1.2

below  is   a list of 2th machines

http://www.ebay.com/sch/i.html?_odkw=asic+miner&_udlo=1800&_osacat=0&_from=R40&_udhi=4000&_trksid=p2045573.m570.l1313&_nkw=cointerra+asic+miner&_sacat=0

Well, I just went ahead and pulled the trigger on two of these from you guys.  I have PSU's ready and waiting.

I believe in you, Benny!  Don't let me down!




it takes amazon payments?  that is really good.

 I have an amazon visa I get 3%  so it is almost as cheap as direct from bitmaintech. 500 - 3%

 is 485 a unit  pretty good.

Just checked out the site and it looks like I can pay with my amazon visa.

So 485 will be my net cost.  I am still waiting on info on my order for two from bitmaintech.
42309  Bitcoin / Hardware / Re: ANN: BITMAIN has Tested Its 28nm Bitcoin Mining Chip BM1382 on: July 13, 2014, 03:56:24 PM
Wow, give them time to ship, they are not late, they are still within their advertised timeframe.

Batch 1 will get sent out soon i'm sure, once they get batch 1 out the door they'll be pumping out like theres no tomorrow!



Why should we give them (more) time... Huh

I already gave them my money...on June 30 ...2 weeks ago...Capisco...?

ZiG

Because they did make it clear when you ordered about delivery schedule?

 Roll Eyes


They stated from July 10 to July 20  …  It is  Just about July 14th in china   so they are still in the first half of the time frame ..  

I am guessing that  16-20 hours from now which is 4-8 pm July 14th in china we may see some tracking info.  Which would still have them be all good for the first estimate they gave.

I hope this is the case as the clock ticks on the window for it to arrive on the 18th of July to my home in NJ is closing. I would like to get it not later then  friday.

But with the dates they gave I may get it in  weds or thurs the 23rd or 24th of july.  if that is the case maybe we get coupons.

You know what would really suck:

 the s-3 are garbage  worse then the s-2's  that would fucking suck.
42310  Bitcoin / Hardware / Re: ANTMINER S3 Discussion and Support Thread. on: July 13, 2014, 03:39:11 PM
I want to buy one of these. I have a corsair power supply that i run 2x r9270's on.

Could i use this for the antminer? If so would i still be able to use both the video cards or would that be over power. I don't know anything about electricity except not to dick with it.


Edit: corsair 1000


yeah trying to run 2x gpu's the rest of the pc and the antminer will be pushing your limits.   if you are running 1 s-3 you can use quite a few different psus to get her done.


completely aside from your question:

I have come up with a design idea for summer use.    think of a  window air conditioner.

I believe  2 or 3 s-3's  with just some plywood and a piece of sheet metal could mount in a window blowing all hot air directly out to the street.

A bottom piece of plywood.
a top  Piece of plywood .
a sheet of metal as a rain shield.

 the psu in between the 2   s-3's mounted fan down with the psu exhaust  out the window.  the top sheet of plywood needs to have 8 holes each one lines up to the pcie jacks on the s-3's

 most noise and heat will go out the window.

  I will make a lot of photos of this once I build it.  I think 20 bucks tops to make it.

  bfgminer -o stratum+tcp://stratum.bitsolo.net:3334 -u my btc address -p my password

crashes so If I want to solo mine on bitsolo.net

 I would like to just click on the start.bat file

philipma - with a .bat file is exactly how I run my bfgminer and that should work just fine - if not you should post a note on the bfgminer thread as there are more people watching it which could help with troubleshooting it.

I've now switched to using a bfgminer.conf file and I start bfgminer directly - no need of a bat file. If you haven't created a config file you can tell bfgminer to save its current running configuration to a .conf file - press [ S ] to go to the settings screen and [ W ] to write the .conf file.

sounds goods

 I did the s I did the w  here is a screen shot my skill at writing is all cut and paste.  I do not know how to write the file.
I would need a screen shot of one written so I could copy it and add in my solo btc info.

Dude - you were right there - all you had to do was hit ENTER! :-)
Or enter a new file name and then hit ENTER.
 duh if you only knew the about of time I have wasted because it took me from sept 2013 to now to learn this.

I must have written in ten thousand words on set ups of bfgminer in the last 10 months.

 Well I finally learned  thanks.

A question about the 6 chip unit what is the lowest power watt per gh  you got .

  set at 45 or 40 freq and tweaking the volts with a different resistor.

 these units could be sold as a long term lottery ticket mined at bitsolo.net


 silent and cool at 40 freq if you could do lower watts per gh .

get one of these with  a bfgminer 4.4.0  program on a usb stick for the programmed challenged.

did you assemble these your self?

 I would love to have one capped at 10 or 9 gh but lower power use due to a different resistor.
 And have the standard one for comparison.

 thanks dave works fine.

 I feel stupid that I have never asked this question.  I did not know it was so easy to do it.

I could do this again and put in a roll over pool correct?

42316  Bitcoin / Hardware / Re: Can this power supply power the Rockminer? on: July 13, 2014, 01:28:10 AM
Im looking to buy possible 2 Rockminers to mine bitcoins 24/7. The one part that im wondering about is the power supply. It seems that everyone uses a BlackArrow power adapter connected to a PSU then they use the 2.5mm barrel jack to power the device. I don't see the difference between that method and simply using this power cable.

The power supply im looking at http://www.amazon.com/Adapter-Power-Supply-LCD-Monitor/dp/B003TUMDWG/ref=pd_sim_op_4?ie=UTF8&refRID=0JXRQGJFNZZSJ9H35RG9

The Rockminer http://www.amazon.com/gp/product/B00KLQHSM6/ref=olp_product_details?ie=UTF8&me=

Another quick question if anyone is familiar with these miners, do i still need to find that special driver online (i forgot the name) or will the device install it after i connect the USB cable?

(If for some reason this double posts im sorry, was having some issues).

that power supply could work the problem is it burns power like a mother fucker.  also it may not be 2.5mm on the inside.

this guy here on bitcointalk makes  cables  

cablez


https://bitcointalk.org/index.php?topic=74397.0


he should be able to make a custom cable for you that snaps into a psu.

I can't wait to try out my 1300w evga power supplies this is my first time using them so i'm looking forward to setting them all up. Anything new regarding batch 1?

waiting and it is hard to wait.

   they are slow because they can not be punished.  they are selling the best miner in the game…  and they have no need to ship it.  the delayed shipping will keep the next jump low.

 we just had a low jump 3%.  so every orders they sold out batch 1 batch 2 batch 3.

 they will list batch 4 sell it out in 2 days. 

then they will ship s-3's batch 1.

 So even though I ordered 17 minutes into the batch 1 open it will ship on the 14th at 11:50 pm china time.  I will be lucky to get it on fri the 18th east coast usa time.


Maybe if I am lucky they will offer a coupon for the delay.  And guess what I will use it and buy two more. 

Just like Oliver in the play. ' Please ,sir, I want some more'
