I had it for more then a week.  but I buy a lot from them with 0 issues.   So maybe a new buyer does not get one for a few orders.

As an edit could lead to fraud, if your account was hacked and the order was put to a new address.

Even if black arrow has tons of chips they are not efficient.  So they are not much to worry about.

I run 9 usb sticks there for shits and giggles.

 i run 1th  and have 1th on order running at btcguild.

plus 55mh mining ltc

I will tell you what go to


http://bitsolo.net


 mine there with 1 usb stick  and have some fun.

or buy this


https://asicpuppy.com/magentoPuppy/index.php/rockminer-r-box-32-37gh-s-40-50-watt-miner.html


and mine it here

https://bitminter.com/

great idea.  pool ops won't do it.  I could show the math and rant and rave why every miner should so some solo mining.  this pool is just that some solo mining.

I could say that
btcguild
bitminter
slush
eligus

should all offer a server link with this or something like this.

100% share
75%   share
50%   share
25%   share
0%     share

I could also say wemineltc should do it.  but they won't.  pools don't want to offer this for lots of reasons.

I won't go into the why of it.  But they wont offer it.

 I mine 15 gh here
http://bitsolo.net/my-account/

I mine 1 th here

www.btcguild.com

I belong to ups choice so I get notice of all ups shipments. so far no notice.

I will post photo give me 1 minute it was under the top view that is in highlights

yes my edit left yesterday.

I could list about 10 reasons for s-3's over s-4'

1) I have 7 psu's
2) s-3's cost less
3) s-3's will downvolt + downclock run quietly
4) s-3's will ship easier due to lower weight
5) an s-3 cost .725 btc this is under 450 usd.  I run a business btc sales under 600 usd involve less paper work
6) I have a spot in an office that will allow for 2 s'3 at 400gh 480-550 watts price for power 2.24 cents a k-watt
7) Im my home I can place them in 5 different rooms when the weather is cold reducing my heating bill by a few hundred usd each month.
no rasp pi needed means no card corruption
9) no rasp pi means auto booting after power failure is fixed
10) no rasp pi means auto booting after net failure is fixed
11) smaller units are easier to sell in 3 -5 months

My home was rewired during 1998 to 2001.

I did every circuit in 10 gauge wire .  I went from 20 circuits to 40 circuits  from 100 amp to 200 amp.

My home was built during the Vietnam war copper shortage. 1970  it was all aluminum wiring except the ac 220 line.

I replaced it all with copper.  I was into music ht subs  and ran many power circuits extra. My garage has 5x  20 amp circuits did it for a speaker building setup a lot of power tools etc.  I had no idea that doing all this would pay off 10 year later as I can run 6k in asics.

 I can run lots of gear and have run 23 gpus using 11 pc's in 2012  .. 6000 watts hot hot hot  earned 1 coin a day.

good I am glad you have a better power number now.   BTW a q-tip with 90% alcohol rubbed across the  8 POWERED DOWN resistors.

Will clean off the pencil and set you back to the higher volts.

I just sold my 3  after I set them back to full power.  The buyer had free power and wanted the higher speeds.

https://bitcointalk.org/index.php?topic=675598.msg7716943#msg7716943   here they are back to full speed. less then 20 minutes time

yeah spot mining at home with a power discount will work.

 figure ways that the heat works for you not against you.

 make deals with people that have access to low power costs.   >>>>  big upside if you find them.. 

I have the one spot 14 cent power is discounted 84% down to 2.24 cents.

  I must not run more then 800 watts.
  I  must make the gear quiet.
 There are places that  s-3's will pay to run.
 I know of 2 developments near my home in Howell NJ that use electric power to heat their home. 

 Old school  baseboard heat  heating bills are 300 a month in small 4 room homes.
 I am attempting to have s-3's mining in one or two of these homes.  This could make nice money for me and the home owner's that I recruit.

you need to understand.  that power has a lot to do with mining


the s-2 can be run on a single 15 amp circuit with power to spare.  in fact if you pull one of the 10 blades and run 9 blades it is very reliable .

  also realize 400 usd coupons are still around.

the gridseed sucks hard on power.

1300 watts for 1.1th

 more like 1350 watts for 1050gh.

you do not have the ability to pull a blade and drop 10%  since it has 5 blades.

so one unit can do 900gh at 900 watts>>> with over head and a spare blade.

the other  1050 gh at 1350 watts

other reasons to get the s-2  a direct upgrade to an s-4 may occur very soon.

Frankly I would not want either one .

 I want a few s-3's  4 to 8 of them.  I have 2 on order right now.  i will wait for them to arrive and get setup then order more.

I sold my 3 s-1's for .2btc each the buyer paid for shipping.   an s-1 to s-3 upgrade will be .5 to .6 btc not .4 .  but i am guessing.


back to shipping of batch 1.   has anyone had a shipping update. it is 11:30pm in china the 10th of July.

 I have to think shipping has started. I placed my batch 1 order in the first hour. so Maybe my gear is on its way.  one can dream.

        https://bitcoinwisdom.com/bitcoin/difficulty        btcwise says  =   17,691
            http://bitcoincharts.com/                              bitcoin charts =   17,140
                                                                             Total             =    34,831 / 2 =   17,415.5   which is  3.55 percent



So with 371 blocks left still under 5 percent.

What this does for me is help my  bottom line on my dragon miner purchased on april 20.

It is getting close to btc roi.  It has done usd roi due to price rise in btc. 

you would need to use the hot air from the miners to heat a coil. then use a fan to blow on the coil.

  thus the air used to cool the miners never touches the food.  I have penciled a few designs that use this approved rack


http://www.lemproducts.com/product/stainless-steel-dehydrator/jerky-food-dehydrators

this is an 800 watt rack .

 if you do no use the heating element   and use 3 s-3's the key would be to transfer the heat and not the air. I have a few ideas on how to do it.

This is an invention waiting for this industry  here is an item that burns 800 watts of power for heat.

Combine the s-3 with this and make a safe dehydrator.

no it does not.  you need a work around.    they are quite a few ways to work around it.     A switch like this

http://www.newegg.com/Product/Product.aspx?Item=N82E16833156251&cm_re=trendnet_teg-s80g-_-33-156-251-_-Product


and this item


http://www.newegg.com/Product/Product.aspx?Item=N82E16833109056


this will allow up to 7 s-3's

I happen to have the switch and  cables for it .  I do not have the tp-link

My listing for the switch is here

https://bitcointalk.org/index.php?topic=683435.msg7751340#msg7751340

I charge the same and toss in free cables.  my switch is new and sealed

yeah if this is possible .  I would do 2 sets…. I have the psu's .

 running 3.2th at 1920 watts  should last into march of 2015 and still pay for the power cost.

No miner pays off in a few months.

Exceptions  are:

 your power is really cheap and or free.

You run a business  that uses electrical power to dehydrate food.

You use electrical kilns to dry lumber.

You buy today and coins go up like mad.-------------mining in this case makes usd / fiat profit.  not btc profit.     say 1 coin at 620 usd   or .5 coin at 2000 usd.  buying and hold a coin may do better but faces different tax law then mining for a coin.

yeah I will just sit on the 5 shares as i am not sending in more money.

  I have a lot gear in house.  maybe I get 300gh for 5 shares I don't know what they are giving.  and maybe coins go to the moon.  but  This looks poor right now.

you are assuming quite a bit saying a dragon will not do roi in btc.  it could.   you have no idea of power cost for someone.  put in 1th with 0 power cost  it will get a lot of coins.
also there is a power wall for asics.  and it will be reached when it is reached growth will slow to a crawl.

if power wall is .2 watts diff will max near 600g   since no one could earn money  even with 8 cents a watt.

and if the power wall is .35 watts diff maxes near 400g at 8 cents

so at a diff of 600g and free power the dragon keeps earning money.

So free power people with smaller rigs will never disappear.

 I made roi with s-1's purchased in may

3 for 1.15 btc     how did i do it.  power at an 84 % discount.  14 cents a kwatt  cost me   under 2.5 cents.   So I will never be fully pushed out of mining due to my power discount.
