I think we safely topped the 200 cap. We could probably even go for a good 300-350 Smiley

I'm curious for the update on the pricing. I'm looking to get a few hashing here fast and I'd rather get them near cost than through another groupbuy at "retail" Wink (or at least, get more miners from this buy for the same amount of money elsewhere)
If we'd have a concrete delivery schedule I'd be looking at a few more to buy Smiley

I am the same as yourself, it is all dependent on the additional costs. If it is low enough then I will happily add to my order.

Excellent, what is your VAT number?

I'll post it on Monday when I'm back in the office

It may have slipped your memory Smiley

And the VAT number is?

Has anyone had an antminer that the fan starts at 100%?

I have one in a very cold room that runs at 100% from the start, I fiddled with the fan wire.. unplug replug etc. no help

Is there a fix for this?
Swap the fan controller leads between the blades to see if the fault follows, if it does you are likely to have a problem fan, if not then the problem is in the blade and providing you do not have any dead chips then just physically swap everything about and it is a s good as new  Smiley

A step in the right direction, now we need peer to peer client hardware with a decentralised location services. A world without the ISP, cable carrier, get closer but is a long way, away yet.

yeah I  admire meshnet and its goals in getting rid of ISP's.

But the core dev/founder of maidsafe has a few criticisms of meshnet which can be found in this video here:

http://www.youtube.com/watch?v=HUHtfkvurFM&list=UUhDck5R_C9i6XTrS66tbwOw#t=629

Not surprised, peer to peer client hardware with decentralised location services are an exceptionally hard thing to do. It is quite a few years away before it even gets out of the data centre.

Is the payment in BTC, Paypal or bank transfer?

Probably:

BTC
Bank Transfer



Then I would be interested in 10 to 20 with controllers

As a noob, one question I have is: I have been able to SSH to the AntMiner. Is there a way to view the cgminer screen?

Same question here Smiley

I'd love to be able to see cgminer output through screen too !
screen -r doesn't work, maybe its in the code but I don't know what the command is

Screen, as already told, isn't installed
We need to know what process is doing the multitasking, or if cgminer is run in a "silent mode" that is not showing outputs

cgminer is fired up as part of the boot process from init.d with the --quiet option

So no cgminer screen? Sad

The script is open to edit and there should be more than enough memory left to run screen, the is also a package for it at http://downloads.openwrt.org/snapshots/trunk/ar71xx/packages

I was going to play with better cooling this weekend but now I have multiple choices, cooling, screen or wash the cars  Smiley

I was also interested in the cgminer screen and been playing around with it.  The way the Antminer S1 is setup is quite complex.  Convoluted is a word that comes to my mind, but it's because it's too difficult for me to follow.  I had to face up to it, as I really wanted to play around with the idea of a multi-pool strategy and luckily for me giletto already started a thread listing the files that were needed to be modified and in doing so, I had to deal with the logic ("flow") of how the Antminer is setup.  I now have a working load-balance strategy with quota on both of my Antminer S1's (all 3 pools are active with percentage settings for each pool).

Back to the post subject.  Antminer S1 "daemonizes" the cgminer application via busybox tool start-stop-daemon during the boot  (/etc/init.d/cgminer) and sending it to the background.  If we modify that, the cgminer may "freeze" the boot up process as it continues to stay in the foreground.  We need screen to replace the start-stop-daemon as we don't wanna have a risk of  bricking the device if it doesn't finish the boot up.

The Antminer S1 has a recovery mechanism by way of a cron job that checks the status of the cgminer and start/stop as necessary and restarts the process, through a series of checks of application logs (shares completed, time stamps, etc.).  Nice.

So, for fun as I wanted to see the cgminer active screen; I ssh'ed to the Ant, killed the crond application and the cgminer application.  Started cgminer with the --bitmain options and 1 pool setting, and the screen shot is below.  My password has a $ in it which messed up the pool login, so my hash didn't show up on the pool.  The miner status Antminer web page showed empty everything, but I can clearly see the miner is very active.  I brought up my Anubis, but it couldn't connect to this particular Antminer, only to the other one.
...

Okay, it was raining so I played with this.

The short answer is that it looks as if the binaries were built without curses so without a new build this is never going to display the standard looking screen for cgminer.


The scripting side of the Antminer is messy, leaves a lot to be desired but does work. It also setups a lot of options but doesn't use them, I find that really irritating because it is easy to clear up. I suspect that during development they set everything from the scripts and as time went on enabled or forced the option in the build instead but never cleaned up the scripts.

Open circuit boards, thermal grease paint again.

The thermal grease that Bitmain uses is silicon based, it is not conductive.

If you price in USD then you might want to state that the price is including or excluding UK VAT as you USD buyers will be able to claim it back.

We are already VAT registered and our listed prices are inclusive of VAT. We also have an EROI number for exporting from the UK.

Well..I have flashed three of the miners back to 3.8.5 and nada..................................

will they mine to other pools??

What router do you have, older cable or sat ones have limitations set on the number devices?
What is the response from the Nslookup diagnostic, some routers will allow ICMP protocol, ping and traceroute regardless of the number of device limitation but not TCP?

Anyone in the UK received one yet, how much was the invoice for and the taxes, charges that had to be paid?

Just to clear up a couple of points:

Are prices are displayed in dollars online for quick price comparison but during checkout your payment will be made in GBP as we are registered in the UK

Our prices might not be the cheapest on the market (We are working hard to reduce this) but we will be delivering within 3 weeks from order not months

I can now confirm out units will be shipped without a PSU, the website will be updated to reflect this on Monday

So as you are expecting to have more than £19,250 of sales next quarter you will have registered for VAT, what is your VAT number and do your prices include or exclude VAT?
78  Bitcoin / Hardware / Re: 750 GH/s - 3TH/s Miners from $3565 - www.bitcoinultra.co.uk on: February 22, 2014, 09:33:21 AM
why in dollers?

Although we are based in the UK the market for Bitcoin mining hardware generally quote prices in USD.

BEWARE! Don't price/buy in $, if there is a contract dispute you'll have to duke it out in a US court, because it's not legal tender in the UK, your trade will not be recognised by the UK courts! US also taxes all $ based barter trades (commodity swaps)  Wink

 

It has nothing to do with the currency it is price in, it could be priced in jelly beans.

It is where the sale occurs that is used to decide the jurisdiction and the UK Distance Selling Regulations are very clear. The company is registered in the UK and the company offices are in the UK therefore all sales regardless of the currency used, or final destination of the goods come under UK jurisdiction and any dispute will be held in a UK court. It also means that if the company goes over the VAT threshold of £19,250 of sales per quarter then thy must register for VAT and 20% extra needs to be added or taken from the price, non EU residents can claim that back.

The only caveat is if the company has an overseas office and can prove that the invoices and receipts for the online presence and sales are paid to and from the accounts of that overseas office, then the jurisdiction is expected to be in the overseas location but even that can be appealed against.

I think that you should call it Stuart.

I thought George would be a better name.

For those of you that use their Ants wirelessly, I have a question:

if I connect a 5Dbi antenna and put my Ant downstairs one floor beneath the router, directly underneath the router, I should be able to get a good signal right?

That depends on how think your floor is, how much metal is in it, how good your router is, and, and, ,,,, try it and see.
