Block Erupter Tube Sales Information Thread [Round4, Price at <1btc per TH/s]

[xhomerx10]

Just out of curiosity, have you tried BTC Guild yet?

[philipma1957]

cool is that while mining? if so which pool?

where do you buy them then? if you order fewer than 10 can you go direct to FC?

yes while mining @ approx. 800 GH/s on the pool that shan't be named.io unfortunately will not connect to eligius.st..  yet!

  any help with how to flash it?

[CanaryInTheMine]

I can handle smaller orders if it's domestic.  I ship same day as long as I have inventory.

I'd pull a 1000W PSU for each if you got 'em.

thanks, they look power hungry

+1   943 Watts for 1 Tube @ stock 270 clock, power eff. was over stated by 10-15%

Looks like round 2 will ship before I receive round 1.

You need to create a subnet of 192.168.0.x on your router...  OR you may need to just change router to ip 192.168.0.1.. Similar to antMiner setups.

Once there you do as FC states @ the beginning of thread type 192.168.0.254:8000/FlashMega into browser, I did this each time I added a new tube set to the chain.

[whonesta]

Another half-dozen on their way. Reselling these looks sketchy so I may as well run them into dust.

oh good i get a break my router is .0. it is a dlink  thanks for the answer  I will book mark this.

I have a place that I pay 15 cents a kwatt then get an 84% discount on the bill  so I pay 2.4 cents a kwatt.  

I can only use about 1000 watts maybe 1200.  I think I will run the one into the ground.

that is the miners psu for sure I have 2 along with some more expensive seasonics

i was looking at the same PSU - note: it's available on newegg http://www.newegg.com/Product/Product.aspx?Item=N82E16817438011  and they accept bitcoin with a $30 rebate.

How to run on pools other than ghash.io and btcguild with Raspberry PI and bfgminer

    1.Modify /etc/apt/sources.list on your Raspberry PI

    deb http://mirrors.ustc.edu.cn/raspbian/raspbian/ wheezy main non-free contrib
    deb-src http://mirrors.ustc.edu.cn/raspbian/raspbian/ wheezy main non-free contrib

    2.Update the aptitude package on your Raspberry PI

    sudo apt-get update

    3.Download bfgminer

    wget http://luke.dashjr.org/programs/bitcoin/files/bfgminer/4.7.0/bfgminer-4.7.0.zip

    4.Uncompress

    unzip bfgminer-4.7.0.zip

    5.Install dependencies

    sudo apt-get install autoconf libtool libncurses-dev yasm curl libcurl4-openssl-dev libjansson-dev pkg-config libudev-dev uthash-dev libusb-dev libevent-dev

    6.Enter bfgminer directory

    cd bfgminer-4.7.0

    7.Run configuration

    ./configure

    8.Compile bfgminer

    make

    9.Run bfgminer

    ./bfgminer  -o stratum+tcp://stratum.f2pool.com:3333 -u <workername> -p 123 --stratum-port <port(3333 by default)> --set-device PXY:diff=<difficulty(16 or above recommended)>

    10.Set static IP for Raspberry PI(modifying /etc/network/interfaces)
    Take the IP address 192.168.0.100 as an example. Replace iface eth0 inet dhcp as:

    iface eth0 inet static
    address 192.168.0.100
    netmask 255.255.255.0
    gateway 192.168.0.1    

    netmask and gateway are decided by your Raspberry PI's local network settings.

    11.Configure ethernet controllers

    Same example as above. Modify the pool address on ethernet controller to 192.168.0.100 with port 3333.

So, news. I talked to ckolivas earlier and he helped me out. I directed a Tube through his hardware and he tracked down the issue. For one, there was indeed exactly the problem of the extranonce2 field always returning 4 bytes (I had mistakenly supposed 8 bytes but after looking at some source when it says '8 chars' in the error it means hex characters, two per byte) when the pool requests something other than 4 bytes. He also noted a lot of corrupt hex in the packets and it looks like the code was generally a botch job designed to work on their own pool, or maybe just ghash, whatever. In any case, not very good for actual customers.

So he patched the proxy in ckpool (https://bitbucket.org/ckolivas/ckpool) to truncate the extranonce2 and generally fix what was going wrong. I've got an instance testing now with a functional tube and so far it's looking good. At least, it works with ozcoin and slush that I've tested so far. Pools that don't use BFG software, best we can figure.

Yeah I got one from newegg last week, also microcenter had $30.00 rebate, BUT!!  you can only get 1 rebate regardless of store you buy from  . So if you have already used your 1-shot, B&H have lowest un-rebated price and free shipping.

I am attempting to power 5 - Tubes with 4 evga 1300 G2..  fingers crossed!

sidehack make sure I am understanding this right as I am not as technical as you are:

To mine on Slush for example I need to download CK's proxy and run the tubes through the proxy on a linux machine or as FC explained above purchase a Raspberry and make the described changes and basically proxy through it???

Thanks in advance.

[sidehack]

I've had one of these on stock clock running off one of my D750 PSU setups for just shy of 10 hours straight, behind ckpool proxy pointed at ozcoin. Currently a 7-order difference in accepted shares versus rejected, reporting 816GH on the device and about 900GH at the pool, 98.4% efficient and 0.11% hardware errors. I'll test it out on some other pools later and see what looks like it should work. Probably any pool reported earlier with the same error response as ozcoin (so probably based on the same stratum backend code) would work just fine. I noticed some other pools, eligius and others using BFG stratum code, seem to hose the works again.

Install ckpool's proxy on a linux machine and punch in your pool and worker info into ckproxy.conf, point your Tube at the proxy.

I haven't ever messed with BFG as a proxy, but I don't think it requires a pi to run. If you got a linux machine the instructions probably aren't that different for installation.

Can you  make some photos  of your Asic-miner tube ? I'd like to see it at work . Thanks .

[sidehack]

Maybe once I'm done assembling them all. I got 31 total to put together and it's a five-step process, one step involving the installation of 156 screws.

Wow those are some good PSU's my kill-a-watt reading for 1 tube is 940+ Watts at stock 270 clock, I would not feel comfortable running that much juice over PSU rating.

[sidehack]

Yeah I read about 930W, which would be around 10% over rated output but these server PSUs are pretty good. I've not pushed one of the 750W that hard before, but the 2000W we've run at 2500W for seven days continuous without issue.

My tube arrives tomorrow.  From reading this thread am I correct in my current assumption that If I don't get a ras pi or Linux machine I have very limited pool choices ie 2 pools?  There is no windows or direct mining solution yet?

BFG 4.7 is windows compatible, it is in the software thread. I am going to give it a try with the command line FC posted above when mine come in.
Here is the cmd file I made to launch it:
Cd\
cd Bit/BFG
bfgminer -o stratum+tcp://stratum.bitcoin.cz -u xxxxx.worker9 -p xxxxxx--stratum-port 3333 --set-device PXY:diff=825
