First off, started using this monitor Saturday and it works/looks great! Very good job. Got it running on a Beaglebone black using Bfgminer as a proxy and every
thing is smooth. One thing I have noticed though is the weird way error and reject rates are calculated. Seems it is based on difficulty 1 shares. My proxy is set to
accept diff128 shares so these figures are waaay inflated. Is there a way to edit the way these are calculated. I also use Anubis and was able to change these figures
in the Php code with it. Could this be done here?

I've been round and round with my 2 tubes trying to hash at Eligius. Tons of disconnects at the controller. BFGMiner4.7 keeps popping "Error from buffer event". Sometimes it will continue working with out a hard reset. Has anybody else been experiencing the same problem? There is an ISP programming connector on the controller. I'm wondering if anyone has tried to connect to it serially with a usb to serial adapter? Its probably a terminal connection. Oops there it goes again, gotta go reset them.
As I understand it the prisma comes with a USB CP2102 based serial adapter. Asicminer/Friedcat has released a tube/prisma specific version of Cgminer that works with this. I have been trying myself to modify some old block erupters into serial adapters. I used Eligius for a long time but got so fed-up with the controller and Bfgminer as a proxy disconnecting that I switched to Ghash.io. Maybe the Cgminer version will allow me to hash at Eligius again! |

I have had a memory leak since using version 4.7.0. This is running as a proxy only on a Windows 7 x64 machine. The memory use grows to over 600Mb over about 2 days. It is a proxy for 4 Raspberry Pi's using Cgminer 4.3.4 with the Bab driver. About 2.2Ths. I restart it and repeat. This behavior is happening with the 32 and 64 bit versions. Pool is Ghash.io (I know...)  Also, I do not know if this memory use issue started with 4.7.0 as I replaced 3.10.0 with it. Version 3.10.0 did not do this. |

I have noticed that there are a considerable number of orphaned BTC blocks in the last 48 hours. I haven't really payed attention to it before but is this normal?
I am beginning to feel as if their servers are overloaded. My miners are getting bounced around to three different servers even though I have specified us1.ghash.io. This results in higher stales. I do not know if the two are connected but it would be logical. |

Awesome! Are you going to offer these as a kit? Would love to assemble one.

My small farm is still profitable. And now with winter just around the corner I can have subsidized heat for a few months! About half of my miners have been running in outdoor temps all summer but are going to get brought in to stay at their "winter home". Also if you have enough hardware of different sorts running as a home miner, it starts to become a lot like a second job. Maybe I just fiddle with my equipment too much.  |

If mining becomes unprofitable I will indeed turn some of my equipment off. However, If everyone does this and the difficulty drops, I can just turn it back on!
I think a lot of persons would do this also. I believe we are reaching the point where the "arms race" is coming to an end. The risk to develop/design/plan/manufacture
new hardware is just not worth the return. Most of the big money in mining hardware has already been made. Maybe this downtrend is the hardware makers cashing out
some of their coins.

I was just curious. I am a hardware guy so the details of this stuff interest me.

Chips on the V1/V2 blades were BE100 - gen 1. Chips on the V3 cubes were BE100 but shrunk - gen 2. Chips on Tubes are BE200s - gen 3.
Hmm. What process where the V3 cubes? 65nm? I always thought they where the same chips. But I have never seen a V3 cube in person. |
|
|
|
Would it not be gen 2.  The original block erupters where BE100 and these are BE200. Why does everyone refer to it as gen 3? Did something come before the BE100? Maybe FPGA? Can anyone enlighten me? |

I wish it was just experimentation. More like "repair". Got a bad tube blade and having trouble getting an RMA. I have thought of that.  Edit: anyone have a 5 chip rockminer for sale cheep? |

Looking to buy around 5 BE200 chips. PM if you can sell this low of quantity. Offering $6-$7 per unit. Can pay with Bitcoin at Coinbase rate as well.

+100 @ philipma1957 I turned handles "outward" and added a fan, FINALLY got these Tubes to stop with the thermal runaway. Also +1 @ friedcat "they" handled the RMA on my burned up board, no additional costs.  How did you get an RMA? I purchased through Canaryinthemines's GB and can't get a response from him. Did you E-mail help@bitquan.com? It has been 2 days and not a peep from anyone.  |

Still have not heard anything at all. Starting to get worried. Maybe he is on vacation? Sent E-mail to canary.btc@gmail.com twice. Sent E-mail to help@bitquan.com. Anybody got any spare chips? Looks like I am going to have to fix this myself. |

PM'ed and E-mailed yesterday, and haven't heard anything yet. He is most likely just busy.

Has anyone had this happen:  Put unit together, powered up with power supplies that had been running another tube for about two weeks, about 10 minutes and POP! Now the first tube is back in that spot hashing nicely. The one with this bad chip is elsewhere hashing on three boards. Does anyone have any experience with the RMA process? |

I have a board with one burnt out (popped) chip. Would Friedcat/Asicminer be willing to ship me bare chips to cover an RMA. I can replace the
bad chip myself. This would be much cheaper to ship I think.

Anyone notice block #320234 showing up 16 times! Looks like 16 payments also.  What the heck is going on? |
|

I did. Set Bfgminer to present 128 diff to the tubes. Poolside is set to 1024.
