101  Bitcoin / Group buys / Re: [GROUP BUY3] Bitmain AntMiner S1 180GH/S Ships on 12/20 & 12/21 on: December 17, 2013, 03:06:52 PM
Questions about hosting.

1. Who does the hosting? bitmain or sushi?
2. Can i ask my hosted device (and psu) to be shipped to me anytime? If so is shipping fee included?
3. Do i get http and/or ssh access to "my" device?
4. At end of 3 months what happens to device?

I am finding that it locks up once in a while requiring a reboot.

u can set it to autoreboot if it locks up...

Is there a way to query cgminer or enable --api-enable --api-network as to monitor the hardware?

api is already enabled. By default it only accepts api requests from local hosts.

edit the file : /etc/config/cgminer

it should have a line
Code:
        option api_allow 'W:127.0.0.1'

To allow api calls from say 192.168.1.2, edit it to

Code:
        option api_allow 'W:127.0.0.1,W:192.168.1.2'

Then restart cgminer...

Well I find this http://www.cybtc.com/thread-3396-1-1.html

www.diginforce.com leads to a default apache web server page.

What is the serial/vga cable for?

That's a massive heatsink for 1 chip! The fans don't look like they are soldered to anything either!  Shocked

I am glad that i got my boards and they work well, and looks like good build quality... but if given the chance to go back in time... i would stop myself from making this order.

So you are +1 .............
With a man that did ordered assembly service without having chips to ship and then

No. I don't know his story... +1 to the fact that you were a nightmare to deal with... and treat buyers like shit.

a Lucky Buyer!!!
* 1 AntMiner purchase will enter you 1 ticket in to the total of 300 drawing pool.  After the final miner ships, the winner will be announced by Bitmain.




I bought 4 units from second auction. Does this mean i already have 4 tickets? Or are the tickets only for later purchasers?

The "LAN" interface confused me a bit at first.  I assume it's completely inaccessible and not used for anything, correct?

I think "LAN" interface is the wifi interface. This seems like a tp-link wifi router... So the WAN interface is what gives it internet, and the LAN interface is the local network this router serves. Now the confusion is due to the fact that we arent using this tp-link module for its intended purpose, but rather like a linux computer.

But there's a separate WiFi interface shown, with its own configuration tab.

A total of 3 interfaces are shown: LAN, WAN, and WiFi.

hmm.. ur right...

br-lan = dunno "br" is usually for "bridge" ( marked LAN in web ui)
eth0 = wifi most likely .. or maybe not. the wifi setup shows "radio0".. but even ifconfig -a doesnt list it.
eth1 = ethernet ( marked WAN in web ui)
lo = loopback.. i.e. when device wants to talk to itself (127.0.0.1)

Having never played with openwrt, id guess that the "LAN" interface is probably some kind of virtual bridge interface to patch itself(or WAN) to the wifi...

Interesting sidenote... the br-lan and eth0 share the same mac address...

In fact, I have been forced to move my HEX16A2 board on a Ubuntu 12.04 x64 machine with your cgminer 3.8.4, due to the fact HexMiner 1.0.0.3 for Windows was too unstable.

Some questions (apologies if they are answered in chilli thread, didnt have patience to read the entire 44 pages).

1) How much max Watts per chilli ?
2) Do they come preflashed? Or i need to prepare a windoze computer to run the flash utility?
3) Is Chilli supported by mainline cgminer? Or need to use a custom fork? If fork then can i see the source?

Our Hardware Machine, BTCO Poseidon is hardware lock. You pay half on website and half on delivery. After the hardware is received, you send us Poseidon unic ID and pay the second payment step and we will send you the unlock serial key.

No way im buying anything with such kinds of locks. Even if this is legit and not a scam, whats to say that there isint any timelock and later they asking for more money to renew the serial?

On the flip side, there is no way a hardware vendor, especially in bitcoin world, would ever agree to such terms. Theres no shortage of people trying to get their hands on it for half the price and then reverse engeneering the design/firmware or just cracking it.

Let's teach them a lesson and get them at half price then (or maybe free if we pay by paypal and we chargeback). But we don't know the prices.

Then you would be the scammer.

My current rig in the morning sun today  Cool

That's 2x BFL 60 Gh/s and 2x BFL 7 Gh/s, all with new arctic cooling fans. I also have 30x usb erupters (not pictured), totalling 144 Gh/s now heating my room.

(previous post about this rig here: https://bitcointalk.org/index.php?topic=7216.msg2999470#msg2999470)



Anyone walking pass, realizes that its mining gear, they will have it in a flash, even though they might have to make arrangements for a ladder  Roll Eyes

That's risky, i thought of the same thing.

I thought on where to get the ladder!!! Cheesy

Oh that's one of those Cougar fans, I just bought 2 of them for my case since the stock ones died after 4 years of continuous use. They're really nice and quiet with the rubber mounts.

they really are. I am strongly considering replacing the other stock PWM fan with one. They look AWESOME and are very quiet, but unfortunately have lower airflow. (box says around 75CFM, while the stock fans must push over 100CFM).

BTW: anyone have good liquid cooling ideas or methods? It would be pretty sweet if the antminer boards could be placed into immersion cooling, but i know that they would require a radiator capable of >400W for each antminer which i imagine is costly and semi-complex to install

AFAIK liquid cooling (waterblocks) are not really ideal for ~200W (per blade) spread over a large area. The blocks would tend to be expensive. They are usually made for higher densities. For an ant you would likely need to get slabs custom built... then mount the blades onto it. I did see some early avalon threads where someone got custom waterblocks made... and used a chiller to cool the water.

Immersion cooling could work, just need to figure out how to keep the solution cool...

I think liquid cooling is waste of money... unless you can overclock it to the point of justifying your investment.

edit: found the thread https://bitcointalk.org/index.php?topic=211825.0

wow thats a massive aluminum heatsink lol. I was thinking along the lines of immersion cooling (single or dual phase, though single phase would obviously be cheaper and simpler to build and seal)

if it would work with the heatsinks removed, you could put 4 antminer blades (total 400GH in aircooling, ~900W) into a tank as small as [12"L x 6"W x 8"H] and have space for liquid to circulate. With the heatsinks, the width would be closer to 12".

I think heatsinks still needed for single phase.

The big problem still is how u gonna cool the liquid... You still have to deal with the same amount of heat to remove. Immersion is good for 2 things.
1) Have a buffer zone. If u generate heat in bursts, like typical computing, gaming, etc where you run it at max power for short times and not 24x7. You only have to deal with the average. - Not applicable here.
2) Channel heat elsewhere where you can exchange it more efficiently.
