I'm pretty sure Claymore isn't going to release anything for linux anymore. Perhaps he will, but i don't think so..
I'm running claymore's v9. 3 ZEC miner on linux (ethOS), but can't speak for any of his other miners running on linux. I probably should upgrade since v9.3 is out. I probably should to do a comparo between the latest from optiminer and claymore. Edit: I just upgraded to claymore v9.3 and will check to see what flypool reports as my 24hour hash rate. Currently it reports 141.4 H/s. upgrade from 9.2 to 9.3 produced a yawn. rate is the same at the pool after almost 24 hours. |

not sure they can do that make a 18-19 inch rack mountable unit due to with or length of mobo.
the wire shelf systems with 24 inch wide 14 inch deep 72 inch tall look perfect.
agreed, they would need to change the exterior width dimension of the case by ~21mm from 503.5mm to 482.6mm to get it to fit, and judging from the pictures the mobo is already a tight fit. yep, looks that way. It would be an interesting engineering exercise to see how many GPUs they could fit in a standard 2U full depth (87.3mm high x 445.5mm wide x 730.2 mm deep) enclosure. This would fit in a standard datacenter rack (dimensions taken from an HP DL380G9 without a bezel). |

The only issue for me is I need that density to fit inside an enclosed rack. Don't have option of using shelves as described, wish I had more room at home.
that's good feedback for Pandaminer, i.e.: make the enclosure so it fits in a standard 42U rack, and include mounting tabs. https://en.wikipedia.org/wiki/Rack_unitIn the meantime could you put shelves in the enclosed rack and put the miner in so the 20" dimension is front to back? Yeah, the fans wouldn't be facing in optimal directions, but it might work. |

Good effort But I think it will be a drop in the ocean. I hope I'm wrong  Unfortunately you were right, but luckily a few hours after my rentals ended someone else found a block  https://blockchain.info/block-height/443907which is showing as orphaned Block is good.  edit: changed block state |

I found an Antminer S7 with bad firmware ending soon on ebay that is currently at a price I can afford. I think the fact that I can save on the shipping fees living in the same city as the miner is located in, may make this a great deal for me. My questions are: 1) Is the idea that I could save money on an S7 with bad firmware sound? 2) How difficult would it be to get a s7 with bad firmware up and running? 3) What are the steps involved in relishing the bad firmware if I do not have a way to access the miners I.P.? I will post a link to the Antminer so you guys may have a better idea of what I am looking at, Thank you in advance. http://www.ebay.com/itm/Bitmain-AntMiner-S7-Was-hashing-at-over-4-7-TH-s-as-is-not-working-NOT-S9-/232191226447?hash=item360facf24f:g:pRUAAOSwnHZYZwASIt's only a great deal if you can get it working. Maybe. Start by using the search feature on this site to see if anyone else has figured out how to "fix" the problem described. The S7 has been around for a while so someone has probably had to recover one from an upgrade gone wrong. Check the Mining Hardware sub-forum to start. If you plan to run this in your house just know that it is LOUD and produces a lot of heat. Oh, and that heat is produced by burning electricity. If electricity is free and you don't care about your hearing, it might be an OK deal. I have an S7LN which was lower noise (and lower hash rate) to start, but which was then made even quieter by sidehack (a user here) who hacked the power code to run at a lower voltage reducing the power draw to just 450 Watts which lets me run the miner with the fans at 20% which makes it quiet enough to be in the home office next to me, and helping to heat my home. YMMV and you'd be well served by doing you research first. Cheers, - zed |

@Zed
Thank you for setting the realistic explanation of what to expect and for the tips! I will definitely start with Bitcoin but will also keep an eye on the other SHA-256 coins to see which one may return a better return. I've tried most of the sea-256 coins, and had no luck. Probably me, but my S7LN was not reliable on any pool until I pointed it at a P2Pool node. The Compac on the other hand has similar "issues," but eventually get shares accepted at pools. Heh, yeah at first multiple GH sounds good...until I notice that the network is in PH :-O. check the number of digits in the network hash rate, and I think you will see that you are off by three orders of magnitude.  The current network rate is ~2.48 EXAhash (10 18). The idea of the "lotto" mining sounds pretty fun :-P GL with the pool, let me know if you'd want some other miners! Sure. The node is still syncing the blockchain. It's on block 440,750 as I type this, but man is it slow. I'll post when the P2Pool node is "sane." Lottery mining keeps the lights on. On the miner that is.  @spazzdla
Yep, just a hobby....for now. This is pretty much for fun until I can build a good gaming PC, which I will use for mining occasionally. I am kinda nervous about the set-up because I have practically 0 coding experience, but hopefully a friend can help with that. Since the rPI I am proposing comes with an OS, that should help quite a bit.
If you are going to mess around with GPU mining and altcoins (Ethereum, Zcash, etc.) be sure to check out the altcoin sub-boards. There is a ton of info there, and is where I got started. Don't bother trying to mine Bitcoin with a GPU unless you like pain. GPUs don't have enough horsepower compared to an ASIC. Gaming and mining don't necessarily go together, but they can if you do not care about return on investment (ROI). phillipma1957 and eliovp are two people who have a boatload of info and know what they are talking about from my experience. There are others, but you will figure that out when you start reading. I went down the path of a dedicated single GPU mining rig. I've posted the setup in a few places, and there is a link in my sig to "live" data from it. As long as it is fun, and you aren't too serious, you'll be OK. Cheers, - zed |

This is just for a hobby right?
I have had a hell of a time attempting to get my ACIS's running on my Raspi.. still haven't got it working.. I am not very good at Linux though.
Try here: https://github.com/michelem09/mineraseems like a pretty straightforward install (says the bozo without a RPi) and includes the latest bfgminer and cgminer code built-in. Cheers, - zed |

Thank you both very much for your advice! I will look into Sidehack projects as well as substitutes to bring the costs down on what I listed above.
FWIW, I forgot to say in the OP but I plan on joining a pool for either Bitcoin or other SHA-256 currencies. Also, my plan would be to start off with one USB miner and pick up miners along the way.
Sidehack sticks are well worth it- bought one so far and I plan on buying one of the BF16s (if you want better bang for your buck wait for the BF16 as it's cheaper per GH and more efficient). You're also supporting the community instead of some company more focused on profit than the miners. I started with S3's in 2015 and now I have 2 S7s and a S5 in my house hashing away. Glad to see someone taking a similar path as me I started with CPU/GPU mining in late 2011/2012 at the cusp of FPGAs and ASICs in bitcoin, but went down the path of litecoin which I could mine with my computers with crappy GPUs. I came back to the bitcoin world about a year ago and now have a Gekkoscience BM1384 Compac and a Bitmain Antminer S7LN that sidehack tweaked to adjust the power so it draws 450 Watts and generates 2 TH/s relatively quietly (fans at 20%). I, too, will be looking to purchase some of the BF16s as well. I'm waiting for a full bitcoin node to complete downloading/syncing the blockchain and then I will start my own P2Pool node where I will point my miners. Welcome to the club of hobbyist miners. Supported by sidehack and others. Cheers, - Zed |

Good luck. The challenge with most of the USB stick miners is that they don't have a high hash rate. Yes, multiple gigahash may sound like a lot, but in the grand scheme of the bitcoin mining universe it's almost unnoticeable. This site gives you a reasonable idea of what the bitcoin network looks like: https://bitcoinwisdom.com/bitcoin/difficultyIn the top left corner is the bitcoin network stats, and in the top right is a way to estimate how much you might earn before factoring the cost of your electricity. Here is a screen capture of the details for my Compac that has been overclocked to 325 MHz and turning out ~17.8 GH/s:  I updated the price per bitcoin (BTC/USD) to 1021 which I got from this web site: http://coinmarketcap.com/currencies/views/all/As you can see my Compac miner might earn me 10.07 US cents per week before I factor in the power to run the hardware miner and the power to run the computer where the mining software runs. If you look at the fraction of a bitcoin/day, 0.00001409, please note that's not much at all. It's considered "dust", and in fact wouldn't be paid out by most pools. So what I, and a number of others do is use these Compac miners as "lottery miners" running them on a solo pool, I use solo.ckpool.org (see the link in my sig) and "play" in the gekkoscience fun-run on gekkorun.de: https://bitcointalk.org/index.php?topic=1452817Cheers, - zed |

I agree with notlist3d, you could save a few bucks by changing what you get, and unless you hit a lottery solo block, you will never earn anything with the miner. Definitely look into getting on the list for one of sidehack's new 2Pac miners. Check out the thread that notlist3d provided for details. There is also this thread with more info: https://bitcointalk.org/index.php?topic=1651958.0 and somewhat more of a roadmap of his USB home/hobby miner project(s). I don't think that the USB hub that you have chosen will be sufficient to power the Compac miners. According to the description on Amazon: "Each USB port on our 12 Port hub will only provide 5 volts 250 Milliamps," which isn't a lot of power per port. The good powered hubs can provide 5 volts and more than two amps per port. I have a Superbpag 7-port USB hub: https://www.amazon.com/Superbpag-Portable-Charger-Transfer-Samsung/dp/B013OK10YMIt is not the cheapest, but it works great and my Compac, which has the voltage turned up to 0.800 and is overclocked to 325 MHz, has been hashing away since 29-November without a single hiccup. It would have been up for longer, but I was helping -ck test his new pool code, and that required stopping and restarting the miner. https://bitcointalk.org/index.php?topic=1173963.msg17225686#msg17225686Cheers, - zed |

Btc is just about 1000 usd
I sold 1.007 coins at coinbase.
I wonder if rally gets us over 1000 today.
It's close. Last check a moment ago showed $999.82 |

You can actually help the miners on your node. Right now, you are relying upon the node to determine the share difficulty it will accept. Standard p2pool code will base the difficulty on the combined hashing power at the node. When there is a great disparity (like yours), the smaller miners are subjected to a much greater variance. Sure, each share found is weighted higher, but the larger variance means the small miner might miss out on payments because they don't have any of the heavily weighted shares on the chain. The solution is easy, and is something you can do to help. P2Pool allows a miner to determine his own share difficulty. This will override the node's setting. You implement this by using a "/" at the end of your BTC address. For example, if you want the node to only accept shares from you above 100,000,000, then you would put the following as your username: This way the other, smaller miners on your node aren't penalized. The node won't count your hash rate in the calculations of share difficulty. Now, the smaller miners will find more, less-weighted shares, and you will find the more heavily-weighted shares. Everyone wins. Thanks Jonny. That's pretty cool, and good to know. I have not had time to dig into the P2pool code yet, but may have some time now that the holidays are upon us. |

yeah, looks like I got shares from ~6:30am - 9:30am (EST) when it looks like all of your miners had stopped. There was another break that looks like ~6:15pm - 8:00pm (EST) where I got a few more shares.

Looking at the only miner besides myself with 2th, I assume it's zed, he should expect to find about 1 share per day on my node, whereas if he set up his own node or mined on another node that was smaller he should expect to find shares more often although they carry less weight than when found on my node. That is indeed my 2th machine. When I pointed the miner at your node I started looking at p2pool stuff, and am, in fact setting up my own p2pool node. I have set up a full bitcoin node which is in the process of syncing now, but seems to be taking forever or at least longer than I thought it would... When the sync completes I will start the p2pool node and point my miner at it. We'll see how that goes. |

I have this USB hub and it's solidly built and my lone Compac is happily hashing away in it. I had another 60watt hub and it wasn't very good. The Compac hashed, but was constantly having issues. It may not have been the hub, but rather the power supply provided with the hub. That power supply was always overly warm to the touch. |

With the addition of the wireless from the raspi all you would need is a power lead coming out of it for the psu. (yes I know a wired connection is better but if its close enough to a router then why not lol).
I have heard that wifi on the RPi3 is merely adequate due to the onboard antenna. Putting the RPi3 inside a grounded metal case would make it worse. Now, if you modded the RPi3 with an external antenna... |

I'm seeing 6-14% improvement (the numbers are bouncing around from 120-130 on the miner output) from my 24hr average (113.8 ) on flypool.
