Use jumper wires between blades. This reduces the number of pci-e power connectors needed. I made small jumpers and ran them from the yellow/black screw terminals.
One pci-e 6-pin will easily handle the load of two blades at these levels.

I want to update the firmware (MM) of my Avalon 3 blades. What is the easiest way to do this. The instructions here : https://github.com/Canaan-Creative/MM indicate that you need ISE to do this. Would it be possible to just remove the EPROM and flash it with the appropriate hex/bin image? Anywhere I could download a pre-built image? Thanks! |

@PlanetCrypto
I have an electricians clamp meter I got at Lowes that works well. If you have access to one side of your 240V feed, just measure the amps and multiply
times voltage measured with an ohmmeter. What I measured for some of my gear was 12A X 248V =2976W. I measured this right at the circuit breaker.

Arcing is not possible in the senerio. The voltages are WAY to low. You would need hundreds of volts or even thousands to jump even a small amount. http://en.wikipedia.org/wiki/Paschen's_lawThis was current runaway. These chips are most likely a "chained" design used to obtain maximum efficiency. If one chip in the series "chain" shorts internally, it can cause a great increase in current through the other chips in the chain thus causing the temperature to rise suddenly and dramatically. This would literally set them on fire! Somewhere on here I have seen a picture of a heavily burned "one string miner" that used Bitfury chips. These use 14 chips and run directly off the 12Vdc feed in series. So if one ship shorts, it starts an overcurrent condition that very quickly pops all of the others. |

This!
Please bring these servers back up.
Stales are high here in US using UK servers.

I have LOTS of block erupters. They have the original boxes. How many are you looking to buy?
|
|
|
|

I have a TON of old Block erupter USBs. Could these be modified to work? They appear to be cp2102 based and the extra parts can easily be removed with a rework
station.

Where are you located? Interested.  |

Pulled link as requested. I was wondering do you know if FC plans to update the controller's software. To have an auto pool switch option like the antminer s-3's have?
You can do it manually via BFG proxy if its critical for now The BFG proxy starts showing "error from bufferevent" and crashes the controller. Known bug, only solution is to hard reset BFGMiner and the controller for now. This doesn't occur with other pools? O.o Any idea what triggers it? Network solving a block it seems. Had to switch to Ghash.io because of this. |

Pool is down because of this: From: DD4BC TEAM < dd4bc@outlook.com> Hello Your mining server is extremely vulnerable to ddos attacks I want to offer you info how to properly setup your protection, so that you can't be ddosed, at least not with so little power. My price is 2 Bitcoin only. Right now I'm running small (very small) attack which will not crash your server, but you should notice it in logs. Just check it. If I increase the attack size, I could completely crash, it would drop all connections and damage would be big... Don't worry, I will not do it. I want to offer you info on how I did it and what you have to do to prevent it. If interested pay me 2 BTC to 17aLGgw8AwJdqiBtMMG1QtQJgNQQkiyEsp Thank you. I suggest using a backup pool until the situation is resolved. Extortion, nice. People like this are the problem. |

Typical...  My good luck! I just switched to this pool 1 day ago. Last time I mined here it was called Bitparking. Now I am back to Ghash.io  |

HYPster, it happens We're pretty friendly here, unlike a lot of BCT. Do you have any experience compiling windows wallets? +10 love it, by the way do you? Me? no. I'm trying to learn, but I've had so much going on, and no dedicated Windows machine, that I can't say when I'll get it done. I'm pretty good with Linux wallets, QT and daemon. Well Bio, the way you are going with playing with compilers and code you might end up being a coder yourself. Would not surprise me you might be a gifted coder as well.  Looking forward to your 1st project ! I've definitely caught the bug It's likely that I'll learn programming the way I've learned nearly everything else about computers. I will find EVERY way to break it first HA! no kidding! |

Can we "print" our own label and send it to you. I really would not want to spend BTC on shipping. Just name your carrier and give package details.
For me, this would make your equipment much more attractive pricewise.
|
|
|
|
If you got a PM from me yesterday, send me that label. Shipping Monday.
Is this the shipment your already paid for arriving Monday? Are any of the units arriving unspoken for? I generally only buy equipment I can have in my hands within 5 Business days. |

|

Seems like its going up then down now. I will see my miners getting a little hash they drop back to different pool.
^^Seeing the same thing. |

|

whats your rate on a broken s1? just to have an idea..
Depends on what is wrong with it. The amount I would pay is determined by how much work/money I would need to get it functional again. Just PM me with Pictures and what you hope to get for your hardware. |
