Two of my six Antminers. I've made custom covers for all of them, which helps force a lot more air over the heat sinks and chips.
My brother actually suggested that i should do the same about a week ago. He said it will work out much better to reduce heat that way. So, how is it going? EDIT: Doesn't the hot air coming out from one Ant affect the heat of the other? I mean because you have them facing the opposite direction. I usually have them facing the same direction, I just turned one around to take the picture. I have a IR temp gun and found that without the cover, the chips closest to the fans get up to about 103^F and the chips furthest away get up to 135^F. With the covers on, the chips all seem to settle around 118-122^F. Without the cover the heatsink end gets up to 120-123^F, but the cover brings the heatsink down to 115-118^F. If people are interested in covers, I am considering making them for sale. I think they would sell for around BTC .018 - .020 depending on exchange. Powder coated .025" aluminum, would include a bottom plate, back cover with cable pass-thru and top cover. I think you should but you should do it now. Summer is just around the corner, and when something can help bring the heat down.... Have you considered starting up a group buy and see how that goes? EDIT: I can start one for you if you want  |

8 Ants @ 4BTC = 32BTC - Total: 1440 GH/s
27 Ants @ 1.16BTC = 31.32BTC - Total: 4860 GH/s
What would you choose?

I don't think it affects anything else. But I wouldn't rule it out. I disabled NTP on my Ants and I have no problems with my speeds |

I fixed it  Apparently I didn't notice the cnt=0 before all the rest. That has to be commented out as well for it to work. So if you want to manually remove the NTP in the v1.5 Ant you should comment out all the following: cnt=0 if [ ! -f /tmp/cgminer-ntpd-done ]; then while [ "$NTPD_RET" != "0" ]; do ntpd -d -n -q -N \ -p 0.openwrt.pool.ntp.org \ -p 1.openwrt.pool.ntp.org \ -p 2.openwrt.pool.ntp.org \ -p 3.openwrt.pool.ntp.org cnt=$ (($cnt+1)) if [ $cnt -gt 2 ];then echo cnt break fi NTPD_RET=$? done touch /tmp/cgminer-ntpd-done fi |

I reverted all the changes I did to /ect/init.d/cgminer which was nothing but #
Now cgminer starts but unless I disable NTP my miner won't mine.
Why is that?
I didn't have this problem with v1.4
Any body know how I can disable ntp without getting this error?
Could you post your cgminer file? or just the part that you edited for ntp? perhaps some of the script logic has changed. I found replacing "0.openwrt.org" etc. with local ntp servers in the cgminer file sorted all my non-hashing problems out, but only when deleting the "0." also. OK, I have checked both version of my /etc/init.d/cgmirer file and THERE IS a difference. The older version is like this: # if [ ! -f /tmp/cgminer-ntpd-done ]; then # while [ "$NTPD_RET" != "0" ]; do # ntpd -d -n -q -N \ # -p 0.openwrt.pool.ntp.org \ # -p 1.openwrt.pool.ntp.org \ # -p 2.openwrt.pool.ntp.org \ # -p 3.openwrt.pool.ntp.org # # NTPD_RET=$? # done # # touch /tmp/cgminer-ntpd-done # fi The New one: if [ ! -f /tmp/cgminer-ntpd-done ]; then while [ "$NTPD_RET" != "0" ]; do ntpd -d -n -q -N \ -p 0.openwrt.pool.ntp.org \ -p 1.openwrt.pool.ntp.org \ -p 2.openwrt.pool.ntp.org \ -p 3.openwrt.pool.ntp.org cnt=$ (($cnt+1))
if [ $cnt -gt 2 ];then
echo cnt
break
fi NTPD_RET=$? done touch /tmp/cgminer-ntpd-done fi Does anybody know how I can go about it? |

Thanks for the video but that is the procedure I am following and it won't let me update the firmare.
I get the error I have mentioned plus the file input box get's cleared and says: Select a file.
Also, VERY IMPORTANT.
I just checked the System - Startup and CGMINER is disabled.
I click on start but it won't start.
Any ideas why?
If you have a chance, can you check the md5 checksum on the antMiner_openwrt20140207.bin image file? It should be c9e05ef08538f4ed017e611b8ec43a56 cgminer runs as part of the /etc/init.d/cgminer and gets checked by a cron job and restarted as necessary. Did you edit your /etc/init.d/cgminer file? or your /etc/config/cgminer? Are you OC'ed and did you edit /etc/config/asic-freq? Just trying to find out if any of the files are "mistyped" and preventing cgminer from starting up. I have copies of the original files above from factory, but again, my latest Ant was over a month ago, so I don't know if Bitmaintech has changed them.... Yes, I have modified /etc/init.d/cgminer to disable NTP. You think that might be the reason? I have done it on the other Ant and it works just fine. Here is a picture of the startup:  |

Guys I am having trouble with my new Ant.
It doesn't hash!
Everything is all set up properly and I can ping and change whatever I want on it.
However is NOT mining.
I tried to update the firmware but it won't let me.
I get an error: The uploaded image file does not contain a supported format. Make sure that you choose the generic image format for your platform.
I think this might be a firmware thing since this one is a newer version v1.5.
How can I update the firmware?

You have a nice way of saying things.
Well educated, as I can see.
I will ask you the same question as one of the other members:
Do you work for NSA?
Or ANY other agency?
Yes S4VV4s, i work for Milli İstihbarat Teşkilatı, or MİT OK. And what got you guys interested in Bitcoins? So we can monitor you arkadaş! ;-) LOL OK |

I love bitcoin, but I also admit that it has no long term future and it's basically rich nerds trading pogs...that said, I will HODL because some smart guy once said: be nice to nerds, one day they'll be your boss / run the world (can't remember). I'm not saying by bitcoiners are nerds, just that I don't see a value proposition that can't be defeated...but I'm also not divesting I think it was Bill Gates that said that to some students. |

If you check the news http://bitmine.ch/?page_id=863, you should know bitmine is just in co-operation with some Chinese company. They just bought the chip from the Chinese company and name it as "Coincraft A1" chip. The Chinese company can also sell the A1 chip. They can call it any name they want like "ABC A1" chip. So the question comes: Does the "Coincraft A1" chip means "A1" chip？I don't think so. This is something like Mcdonalds can make their hamburger and KFC can make their own too. We do NOT buy chips from bitmine and have no business with them. From that link: Designed from scratch, Bitmine’s Coincraft A1 is a third generation Bitcoin Mining IC developed by Bitmine in co-operation with a team of expert engineers from Innosilicon.
Doesn't say bitmine bought the chip from a Chinese company. I'm assuming that the R&D funds came from bitmine and it's customers and that Innosilicon was contracted by bitmine for R&D, ergo, bitmine retains IP rights of the A1 chip. Unless the use of the A1 chip in these Chinese 28nm miners has been authorised by bitmine, what we're seeing here is corporate theft and entities being in possession of or receiving these miners, liable for a criminal offence. Precisely, we are the owner of the IP inside the A1 chip and the major contributor to the know-how of the inner workings that led to its development. We are aware of things like the one happening here and we even made a press release news concerning this matter: http://bitmine.ch/?p=5178Whoever purchases these does that on its own risk and may be liable in its own country since we hold IP on that. Yes, that's China. Yes, that is China. But China happens to have working 1TH miners and you guys don't yet. So either they are better manufacturers than you are or you already have the miners ready and you are mining with them. So? |

Warren buffet declared bitcoin as useless and strongly believes bitcoin and Cryptos will die in 10 years. He also thinks bitcoin is a terrible investment. This guy has been right ALL THE TIME and is smarter than the piglets and peasants on this forum Also confirms my theory that bitcoin has run its course as an investment Don't underestimate him, Big money will now stay away from bitcoin and I speculate that the price won't return 500% or more http://www.coindesk.com/warren-buffet-bitcoin-currency/Warren Buffet is probably the smartest investor that ever lived. He knows very well how to go about things. And he once said: "I never attempt to make money on the stock market. I buy on the assumption that they could close the market the next day and not reopen it for five years." That being said, have a look at this: https://bitcointalk.org/index.php?topic=498558.0 |

I have no idea of what you are talking about....
I should have probably mentioned that I haven't totally discounted your prediction, just searching for clues. This happened only minutes ago, and I immediately wondered if you two had shared knowledge of what was coming. It's a lot easier to make a bold sounding prediction when you know about something that is coming down the pipes. Did you mean to put a little winking smiley at the end of this post? Like I said, I have no idea of what you are talking about...  |

Really a prediction without some reasons given is not very interesting. And a prediction without a reason is just a guess.
I think that Rawted is saying if you do have a prediction, then you need to share the reasoning with us, otherwise, its just not worth the space of a post.
I mean, I can start a post saying "I'm the greatest" but thats not interesting either. This is bitcointalk, we'd all like to know why you think this and then we might get some interesting discussions going.
Man, you put things in a proper way. Maybe Rawted should follow your example and not go directly to calling me an idiot and stuff. That being said, I cannot share my thoughts for business reasons. Though I could be wrong, I am not expecting anybody to believe me. I have just made a prediction and a statement. If I am proved to be wrong so be it. Does that make me an idiot? No, it just proves me wrong. CEO of blockchain tweeted that there would be big news tomorrow. Were you privy to this news when you made the prediction? I have no idea of what you are talking about.... |
